Description

The present invention relates to an information processing method for a mattress, a method for manufacturing a mattress, an information processing system, and a program.

In recent years, high-resilience mattresses using a binder (filament three-dimensional binder) obtained by three-dimensionally fusion-bonding filaments made of a thermoplastic resin as a cushion have been attracting attention. A mattress using a three-dimensional filament composite has a high repulsive force, which makes it easy to turn over, and also has excellent breathability and body pressure dispersibility, so that it is hard to get stuffy and a soft feel can be obtained. As described above, the mattress has essential features for a comfortable sleep.

As a method for producing such a filament three-dimensional conjugate, for example, the methods disclosed in Patent Document 1 and Patent Document 2 are known. According to this method, a molten thermoplastic resin is extruded vertically downward from a plurality of horizontally arranged nozzles, and then a molten filament having a diameter of about 1 mm is dropped into cooling water and looped by the buoyancy of water. At the same time, a plurality of molten filaments formed in a loop are three-dimensionally fused and bonded to each other to produce a filament three-dimensional bond.

Japanese Patent No. 4966438 JP-A-2010-154965

However, even if a mattress using a filament three-dimensional conjugate having excellent body pressure dispersibility is used, the body shape and the like differ from user to user, so the optimum mattress specifications will differ from user to user. ..

For example, when a user with a wide shoulder takes a lying posture, the weight of the shoulder is concentrated on the shoulder in contact with the mattress and the pressure increases, so that the body pressure dispersibility is easily impaired. On the other hand, if the repulsive force of the filament three-dimensional bond is reduced so that the body can easily sink into the mattress, the body pressure dispersibility is improved, but the buttocks sink and the natural body (upright posture) sleeps. It is not possible to maintain a posture, it is difficult to turn over, and it is not possible to obtain a comfortable sleep.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic perspective view of the mattress 1 according to the present embodiment. Further, FIG. 2 is a schematic exploded perspective view when the mattress cover 2 is disassembled into a top surface side cover 2a and a bottom surface side cover 2b. The vertical, horizontal, and front-back directions of the mattress 1 are as shown in FIG. 1 and the like. Further, in FIG. 1, in order to make it easy to understand the internal configuration of the mattress 1, the approximate positions of the first to third mattress units 3a to 3c are shown by broken lines.

The mattress 1 includes a mattress cover 2 that covers the entire outer surface thereof, and a mattress cushion (composed of the first to third mattress units 3a to 3c) contained therein. As a whole, the mattress 1 has a rectangular shape having sides in the front-rear direction (length direction), left-right direction, and up-down direction (thickness direction), and the left-right direction dimension is slightly smaller than the front-back direction dimension. The vertical dimension is sufficiently smaller than the horizontal dimension.

The first mattress unit 3a, the second mattress unit 3b, and the third mattress unit 3c have the same thickness (vertical dimension) and width (horizontal dimension), and are arranged side by side in the front-rear direction. The mattress 1 is usually placed on a horizontal floor, a bed, or the like, and is used in a form in which the user lies on the upper side. When used in this way, the vertical direction of the mattress 1 coincides with the vertical direction. As described above, the mattress 1 is set to have a longer size in the front-rear direction (length direction), and can be suitably used in a form in which the front-back direction substantially coincides with the height direction of the user.

The mattress cover 2 in the state shown in FIG. 1 has a substantially rectangular parallelepiped shape having a space inside as a whole, and a fastener 4 is provided on the peripheral surface portion. Further, as shown in FIG. 2, the mattress cover 2 can be separated into a top surface side cover 2a and a bottom surface side cover 2b by opening the fastener 4. By putting the mattress cushion 3 inside in this state and connecting the covers 2a and 2b with the fastener 4, the mattress cover 2 can completely accommodate the mattress cushion 3. As the cloth for the mattress cover 2, cotton, silk, linen, nylon cloth, double raschel, mesh cloth, or the like can be used.

The fastener 4 has a structure that is harder to stretch than other parts of the mattress cover 2, and also has a role of preventing the mattress cover 2 from stretching in the length direction (height direction) (role as a stretch prevention member). Fulfill. The fastener 4 is provided so as to make one round of the peripheral surface portion when viewed from above, with the vertical position (height) being substantially constant.

In the present embodiment, a fastener 4 using a woven tape is used as the stretch prevention member, and the fastener 4 is arranged so as to cover the entire joint portion between the top surface side cover 2a and the bottom surface side cover 2b. By opening the fastener 4, the top surface side cover 2a and the bottom surface side cover 2b can be completely separated from each other on the peripheral surface portion. The fastener 4, which also functions as a stretch prevention member, prevents the mattress cover 2 from stretching in the length direction, and prevents the gap between the first to third mattress units 3a to 3c from expanding due to the stretch of the mattress cover 2.

FIG. 3 is an exploded perspective view of the mattress unit 3a housed in the mattress 1. The first mattress unit 3a is a substantially rectangular parallelepiped, and includes a mesh-shaped inner cover 5a that covers the entire outer surface thereof, and a filament three-dimensional bond 6a housed therein. In the present embodiment, the inner cover 5a is provided with a fastener 7a on the peripheral surface portion as an opening / closing member for making the filament three-dimensional coupling 6a detachable. Since the basic configuration of the second mattress unit 3b and the third mattress unit 3c is the same as that of the first mattress unit 3a, detailed description thereof will be omitted here.

The filament three-dimensional coupler 6a is an elastic member obtained by three-dimensionally fusion-bonding molten filaments of a thermoplastic resin to each other. In the process of manufacturing the filament three-dimensional coupler 6a, the molten thermoplastic resin is extruded vertically downward from a plurality of horizontally arranged nozzles. As a result, the molten filament having a cross-sectional diameter of about 1 mm is dropped into the cooling water to form a loop by the buoyancy of the water, and at the same time, the plurality of fused filaments formed in the loop are three-dimensionally fused and bonded to each other. A filament three-dimensional conjugate 6a is obtained. As a method for producing the filament three-dimensional conjugate, the method disclosed in Patent Document 1 or the like can be adopted.

The thickness (vertical dimension) of the filament three-dimensional bond 6a is preferably in the range of 10 to 25 cm. Further, in the filament three-dimensional bond 6a, the filament diameter (diameter of the cross section) is preferably in the range of 0.5 to 2 mm, and the bulk density is preferably in the range of 30 to 150 kg / m ³ . By keeping the thickness, filament diameter, and bulk density within the above ranges, relatively good body pressure dispersibility can be obtained without impairing the drainability and drying property of the filament three-dimensional bond 6a.

In the present embodiment, the filament three-dimensional bond 6a uses a filament three-dimensional bond continuously formed in the vertical direction (vertical direction), but the vertical direction (vertical direction) or the horizontal direction (vertical direction) ( A plurality of filament three-dimensional conjugates that can be divided in the height direction / shoulder width direction) may be used. When the thickness of the filament three-dimensional bond 6a is less than 10 cm, it becomes difficult to obtain body pressure dispersibility in the lying position, and conversely, when the thickness exceeds 25 cm, the filament three-dimensional bond 6a becomes heavy and difficult to transport. Become.

As shown in FIG. 8, the mattress 1 supports a human body in a sleeping posture with its head facing forward vertically upward. The first mattress unit 3a is arranged at a position supporting the shoulder of the human body in the lying position, and the second mattress unit 3b is arranged at the position supporting the buttocks of the human body in the lying position. The third mattress unit 3c is arranged at a position that supports the legs of a human body in a lying position.

The position P0 shown in FIG. 8 is a vertical position on the upper surface of the mattress 1 in the initial state before the mattress 1 (each mattress unit 3a to 3c) supports the human body. Further, the position P1 shown in FIG. 8 is a vertical position of the lower end of the shoulder portion in a situation where the mattress 1 supports a human body in a lying position. The first mattress unit 3a supports a part of the human body in a lying position (the part on the first mattress unit 3a) in a state where the portion at the position P1 is most subducted. The vertical distance between the position P0 and the position P1 is the subduction depth of the shoulder portion in the first mattress unit 3a (the depth of the deepest subduction portion in the shoulder portion, and hereinafter, the “shoulder subduction depth”. It is sometimes called "DP1").

Further, the position P2 shown in FIG. 8 is a vertical position of the lower end of the buttocks in a situation where the mattress 1 supports a human body in a lying position. The second mattress unit 3b supports a part of the human body (the part on the second mattress unit 3b) in the lying position in the most depressed state at the position P2. The vertical distance between the position P0 and the position P2 is the subduction depth of the buttocks in the second mattress unit 3b (the depth of the deepest subduction point in the buttocks, hereinafter referred to as "buttock subduction depth DP2". It may be called). The vertical distance between the positions P1 and P2 corresponds to the difference between the vertical positions of the shoulder and the buttocks of the human body in the lying position.

Further, the position P3 shown in FIG. 8 is a vertical position of the lower end of the leg (near the calf) in a situation where the mattress 1 supports a human body in a lying position. The third mattress unit 3c supports a part of the human body in a lying position (the part on the third mattress unit 3c) in a state where the portion at the position P3 is most subducted. The vertical distance between the position P0 and the position P3 is the subduction depth of the leg in the third mattress unit 3c (the depth of the deepest subduction point in the leg, and hereinafter, "the subduction depth of the leg". It is sometimes called "DP3").

Further, the mattress units 3a to 3c are assigned different model numbers according to the repulsive force (see FIG. 10), and it is possible to form the mattress 1 by using any model number. The first mattress unit 3a has different repulsive force characteristics depending on the model number, but the shape and dimensions are the same even if the model number is different. This point is the same for the first and second mattress units 3b and 3c. Mattress units having the same shape and dimensions but different repulsive force characteristics can be obtained by adjusting the characteristics related to the repulsive force of the filament three-dimensional bond 6a, such as filament density and filament diameter. Further, as will be described in detail later, the adopted model number is determined from the model numbers of the mattress units 3a to 3c in consideration of the user's body shape and the like, and the mattress units 3a to 3c of the adopted model number are suitable for the user.

Next, a method of manufacturing the mattress 1 using the information processing system of the present embodiment will be described below with reference to the flowchart shown in FIG.

First, as a step of step S1, a step of measuring the user's head width Dh, shoulder width Ds, and buttock width Db and inputting the measured values obtained thereby to the user information input device 10 is performed. The measurement and input work may be performed by a store worker or the like, or may be performed by a user. When this step is performed, the user information input device 10 is in a state of accepting the input of the measured value, and the measured value can be input by using, for example, the touch panel 12. The methods for measuring the head width Dh, the shoulder width Ds, and the buttock width Db will be described again. Also, at least one of the measurements and inputs may be automated.

Next, as a step of step S2, the user's shoulder weight Ws, buttock weight Wb, and leg weight Wf are measured using, for example, four weight scales as shown in FIG. 7, and the measured values obtained thereby are measured. The step of inputting to the user information input device 10 is performed. The measurement and input work may be performed by a store worker or the like, or may be performed by a user. When this step is performed, the user information input device 10 is in a state of accepting the input of the measured value, and the measured value can be input by using, for example, the touch panel 12. Also, at least one of the measurements and inputs may be automated.

Next, as a step of step S3, a step of inputting user ID information (information that can identify the user), which is information such as a user's name and address, into the user information input device 10 is performed. The input work may be performed by the user, or may be performed by a store worker or the like on behalf of the user. When this step is performed, the user information input device 10 is in a state of accepting the input of the information, and the information can be input by using, for example, the touch panel 12.

Next, as a step of step S4, the user information input device 10 performs a step of transmitting the user information UF to the mattress information processing device 20 through the Internet line INT. This user information UF includes information on each measurement parameter shown in Table 1 and user ID information.

Next, as the step of step S5, the mattress information processing apparatus 20 performs a step of receiving the user information UF transmitted from the user information input device 10. Next, as a step of step S6, a step of calculating the target buttock subduction depth Tb from the buttock weight Wb is performed by the mattress information processing apparatus 20.

Here, the target buttock subduction depth Tb is the target value of the buttock subduction depth DP1 and corresponds to the target value of the maximum downward deformation amount of the second mattress unit. The larger the target buttock sinking depth Tb, the larger the contact area between the buttock and the mattress, and while the body pressure dispersibility can be improved, the buttock is more likely to sink, so change it according to the size of the body shape. Is desirable. For users with a small body shape and a small buttock weight Wb, the target buttock sinking depth Tb is set small, and for users with a large body shape and a large buttock weight Wb, the target buttock sinking depth Tb is set large. It is desirable to do.

In the present embodiment, the target buttock subduction depth Tb is uniquely calculated from the buttock weight Wb using the following first equation consisting of a simple linear equation. Kb in the first equation is a predetermined coefficient (in this embodiment, as an example, a fixed value of 0.05). In the first equation, the coefficient Kb may be changed in order to suit the user's preference (for example, whether he / she prefers hard or soft) and a wide range of user body shapes. Further, the target buttock subduction depth Tb may be calculated by using an equation different from the first equation within a range not deviating from the gist of the present invention.
Tb = Wb × Kb ・ ・ ・ (1st equation)

Next, as a step of step S7, a step of calculating the protrusion distance Vsb between the shoulders and buttocks from the shoulder width Ds and the buttocks width Db is performed by the mattress information processing apparatus 20. Here, the protrusion distance Vsb between the shoulders and buttocks corresponds to the difference in the vertical direction between the shoulder subduction depth DP1 and the buttocks subduction depth DP2. In the present embodiment, the protrusion distance Vsb between the shoulders and buttocks is calculated from the shoulder width Ds and the buttocks width Db using the following second equation. According to this second equation, half of the difference between the shoulder width Ds and the buttocks width Db is calculated as the protrusion distance Vsb between the shoulders and buttocks, and the shoulders are calculated using the information of the shoulder width Ds and the buttocks width Db. It is possible to easily calculate the protrusion distance Vsb between the buttocks.
Vsb = (Ds-Db) / 2 ... (formula 2)

Next, as a step of step S8, a step of calculating the target shoulder subduction depth Ts from the target buttock subduction depth Tb and the protrusion distance Vsb between the shoulder buttock is performed by the mattress information processing apparatus 20. Here, the target shoulder subduction depth Ts is the target value of the shoulder subduction depth DP1 and corresponds to the target value of the maximum downward deformation amount of the first mattress unit 3a. In the present embodiment, the target shoulder subduction depth Ts is calculated from the target buttocks subduction depth Tb and the protrusion distance Vsb between the shoulder buttocks using the following third equation. According to the first to third equations, the difference between the target shoulder subduction depth Ts and the target buttock subduction depth Tb (Ts-Tb) is the protrusion distance Vsb between the shoulder buttocks. It will be set to match.
Ts = Tb + Vsb ... (Equation 3)

Next, as a step of step S9, a step of calculating the target leg subduction depth Tf from the leg weight Wf is performed by the mattress information processing apparatus 20. Here, the target leg subduction depth Tf is the target value of the leg subduction depth DP3, and corresponds to the target value of the maximum downward deformation amount of the third mattress unit 3c.

The larger the target leg sinking depth Tf, the larger the contact area between the leg and the mattress, and while the body pressure dispersibility can be improved, the leg is more likely to sink. Therefore, it is desirable to change the target leg subduction depth Tf according to the size of the body shape. For users with a small body shape and a small leg weight Wf, the target leg sinking depth Tf is set small, and for users with a large body shape and a large leg weight Wf, the target leg sinking depth is set. It is desirable to set Tf large.

In the present embodiment, the target leg subduction depth Tf is uniquely calculated from the leg weight Wf using the following fourth equation consisting of a simple linear equation. Kf in the fourth equation is a predetermined coefficient (in this embodiment, as an example, a fixed value of 0.05). In the fourth equation, the coefficient Kf may be changed in order to suit the user's preference (for example, whether he / she prefers hard or soft) and a wide range of user body shapes. Further, the target leg subduction depth Tf may be calculated by using an equation different from the equation 4 within a range not deviating from the gist of the present invention.
Tf = Wf × Kf ・ ・ ・ (4th formula)

Next, as a step of step S10, a step of determining the first adopted model number αUs, which is the adopted model number of the first mattress unit 3a, from the shoulder weight Ws and the target shoulder sinking depth Ts by the mattress information processing apparatus 20. Will be done. The first adopted model number αUs is determined so that the sinking depth of the shoulder of the first mattress unit 3a is as close as possible to the target shoulder sinking depth Ts when the user takes a lying posture. To.

In the present embodiment, 10 types of first mattress units 3a having different repulsive force characteristics are prepared, and different model numbers are assigned to each. More specifically, as shown in FIG. 10, 10 types of model numbers Us1 to Us10 are provided as model numbers of the first mattress unit 3a, and the larger the value of x in the model number Usx (x is an integer of 1 to 10), the larger the value. , The first mattress unit 3a has a high repulsive force. The model number Us1 is assigned to the first mattress unit 3a having the lowest repulsive force, and the model number Us10 is assigned to the first mattress unit 3a having the highest repulsive force.

Further, FIG. 9A shows a pattern showing which model number is determined as the first adopted model number αUs from the respective values of the shoulder weight Ws and the target shoulder sinking depth Ts. According to this pattern, among the model numbers Us1 to Us10, the one whose shoulder sinking depth DP1 is closest to the target shoulder sinking depth Ts (that is, the one most suitable for the user) is the first adopted model number. It has come to be determined as αUs.

For example, according to the pattern, when the shoulder weight Ws is 21 kg and the target shoulder sinking depth Ts is 5.2 cm, the model number Us4 is set as the first adopted model number αUs as shown in FIG. 9A. It will be decided. According to the mattress 1 using the first mattress unit 3a of the first adopted model number αUs (model number Us4), the shoulder sinking depth DP1 is used when the shoulder weight Ws is 21 kg. Can be as close as possible to 5.2 cm (target shoulder subduction depth Ts according to the user).

According to the pattern shown in FIG. 9A, if the value of the shoulder weight Ws is the same, the larger the value of the target shoulder sinking depth Ts, the smaller the repulsive force (easier to sink) is adopted first. It is determined as the model number αUs. Further, if the value of the target shoulder sinking depth Ts is the same, the model number having a larger repulsive force (difficult to sink) is determined as the first adopted model number αUs as the value of the shoulder weight Ws is larger.

In the pattern shown in FIG. 9A, a loader is placed on the first mattress unit 3a of each model number, and the relationship between the weight of the loader (corresponding to the shoulder weight Ws) and the sinking depth is investigated in advance by experiments. It is created based on the results of the investigation. Since the subduction depth of the loader changes depending on the horizontal cross-sectional area of the loader, the loader used in the experiment is unified to a rectangular parallelepiped loader having a rectangular bottom surface of 10 cm in length and 20 cm in width. In addition, in order to fit a wide range of user body shapes, a loader having a curved surface shape may be used as the loader, or the size of the bottom surface may be changed according to the weight of the loader.

Next, as a step of step S11, the mattress information processing apparatus 20 performs a step of determining the second adopted model number αUb, which is the adopted model number of the second mattress unit 3b, from the buttocks weight Wb and the target buttocks subduction depth Tb. .. The second adopted model number αUb is determined so that the buttock subduction depth DP2 is as close as possible to the target buttock subduction depth Tb.

In the present embodiment, 10 types of second mattress units 3b having different repulsive force characteristics are prepared, and different model numbers are assigned to each. More specifically, as shown in FIG. 10, 10 types of model numbers Ub1 to Ub10 are provided as model numbers of the second mattress unit 3b, and the larger the value of x in the model number Ubx (x is an integer of 1 to 10), the larger the value. , The second mattress unit 3b has a high repulsive force. Model number Ub1 is assigned to the second mattress unit 3b having the lowest repulsive force, and model number Ub10 is assigned to the second mattress unit 3b having the highest repulsive force.

Further, FIG. 9B shows a pattern showing which model number is determined as the second adopted model number αUb from each value of the buttock weight Wb and the target buttock subduction depth Tb. According to this pattern, among the model numbers Ub1 to Ub10, the one whose buttock subduction depth DP2 is closest to the target buttock subduction depth Tb (that is, the one most suitable for the user) is the second adopted model number αUb. It is supposed to be decided.

For example, according to the pattern, when the buttock weight Wb is 24 kg and the target buttock subduction depth Tb is 1.2 cm, the model number Ub6 is determined as the second adopted model number αUb as shown in FIG. 9B. Will be. According to the mattress 1 using the second mattress unit 3b of the second adopted model number αUb (model number Ub6), the buttock sinking depth DP2 is set to 1 when used by a user having a buttock weight Wb of 24 kg. It is possible to make it as close as possible to 2 cm (target buttock subduction depth Tb according to the user).

In the pattern shown in FIG. 9B, a loader is placed on the second mattress unit 3b of each model number, and the relationship between the weight of the loader (corresponding to the buttock weight Wb) and the sinking depth is investigated in advance by an experiment, and this investigation is performed. It is created based on the results. Since the subduction depth of the loader changes depending on the horizontal cross-sectional area of the loader, the loader used in the experiment is unified to a rectangular parallelepiped loader having a rectangular bottom surface of 15 cm in length and 25 cm in width. In addition, in order to fit a wide range of user body shapes, a loader having a curved surface shape may be used as the loader, or the size of the bottom surface may be changed according to the weight of the loader.

Next, as a step of step S12, a step of determining the third adopted model number αUf, which is the adopted model number of the third mattress unit 3c, from the leg weight Wf and the target leg sinking depth Tf by the mattress information processing apparatus 20. Will be done. The third adopted model number αUf is determined so that the leg subduction depth DP3 is as close as possible to the target leg subduction depth Tf.

In the present embodiment, 10 types of third mattress units 3c having different repulsive force characteristics are prepared, and different model numbers are assigned to each. More specifically, as shown in FIG. 10, 10 types of Uf1 to Uf10 are provided as model numbers of the third mattress unit 3c, and the larger the value of x in the model number Ufx (x is an integer of 1 to 10), the larger the value. , The third mattress unit 3c has a high repulsive force. Model number Uf1 is assigned to the third mattress unit 3c having the lowest repulsive force, and model number Uf10 is assigned to the third mattress unit 3c having the highest repulsive force.

Further, FIG. 9C shows a pattern showing which model number is determined as the third adopted model number αUf from the respective values of the leg weight Wf and the target leg sinking depth Tf. According to this pattern, among the model numbers Uf1 to Uf10, the one in which the leg subduction depth DP3 is closest to the target leg subduction depth Tf (that is, the one most suitable for the user) is the third adopted model number. It is designed to be determined as αUf.

For example, according to the pattern, when the leg weight Wf is 9 kg and the target leg sinking depth Tf is 0.45 cm, the model number Uf5 is set as the third adopted model number αUf as shown in FIG. 9C. It will be decided. According to the mattress 1 using the third mattress unit 3c of the third adopted model number αUf (model number Uf5), the leg sinking depth DP3 is used when the leg weight Wf is 9 kg. Can be as close as possible to 0.45 cm (target leg subduction depth Tf according to the user).

In the pattern shown in FIG. 9C, a loader is placed on the third mattress unit 3c of each model number, and the relationship between the weight of the loader (corresponding to the leg weight Wf) and the sinking depth is investigated in advance by experiments. It is created based on the results of the investigation. Since the subduction depth of the loader changes depending on the horizontal cross-sectional area of the loader, the loader used in the experiment is unified to a rectangular parallelepiped loader having a rectangular bottom surface of 8 cm in length and 30 cm in width. In addition, in order to fit a wide range of user body shapes, a loader having a curved surface shape may be used as the loader, or the size of the bottom surface may be changed according to the weight of the loader.

The information of each pattern shown in FIGS. 9A to 9C is stored in the mattress information processing apparatus 20 in advance as a part of, for example, the adoption model number determination program 32, and the adoption model numbers αUs, αUb, and αUf are determined using the information. It is possible to do. Next, as the step of step S13, the mattress information processing apparatus 20 performs a step of displaying the first to third adopted model numbers αUs, αUb, and αUf determined in steps S10 to S12.

Next, as a step of step S14, a step of manufacturing the mattress 1 by using the displayed first to third adopted model numbers αUs, αUb, and αUf is performed. More specifically, the first mattress unit 3a of the first adopted model number αUs, the second mattress unit 3b of the second adopted model number αUb, and the third mattress unit 3c of the third adopted model number αUf are each of the mattress cover 2. A step of arranging and fixing the inner predetermined position (see FIG. 1) is performed. This arrangement and fixing work may be performed entirely by workers or the like, and may be partially or wholly automated. After that, a step of closing the fastener 4 of the mattress cover 2 is performed, and the mattress 1 is manufactured.

Next, as a step of step S15, a step of calculating the protrusion distance Vsh between the shoulder temporal regions from the shoulder width Ds and the head width Dh is performed by the mattress information processing apparatus 20. Here, the protrusion distance Vsh between the shoulder temporal regions corresponds to the difference between the height of the lowermost vertical portion of the temporal region and the height of the lowermost vertical portion of the shoulder in a user who takes a lying posture in a lying position. do. In the present embodiment, the protrusion distance Vsh between the shoulder temporal regions is calculated from the shoulder width Ds and the head width Dh using the following equation 5.
Vsh = (Ds-Dh) / 2 ... (Equation 5)

Next, as a step of step S16, a step of calculating the lying pillow height Ph from the shoulder-temporal protrusion distance Vsh and the target shoulder sinking depth Ts is performed by the mattress information processing device 20. Here, the pillow height Ph for the lying position corresponds to the vertical distance between the temporal region of the user who takes the lying position in the lying position and the first mattress. In the present embodiment, the lying position pillow height Ph is calculated from the shoulder temporal protrusion distance Vsh and the target shoulder subduction depth Ts using the following equation 6. The value of the pillow height Ph for the lying position calculated in this way is a good value as the height of the pillow used with the mattress 1 by the user who takes the lying position in the lying position, and is useful for manufacturing such a pillow. It becomes information.
Ph = Vsh-Ts ... (Equation 6)

Next, as a step of step S17, the mattress information processing apparatus 20 prints the user ID information, the first to third adopted model numbers (αUs, αUb, αUf), and each information of the pillow height Ph for lying down on the tag. The process of processing is performed. Next, as a step of step S18, a step of attaching the printed tag to the mattress 1 is performed. This step may be performed automatically by, for example, the mattress information processing apparatus 20, or may be performed manually by a person.

The mattress 1 is manufactured by the above series of steps (steps S1 to S18). After that, by packing the manufactured mattress 1 and shipping it to the user's address, the user can obtain the mattress 1 suitable for his / her body shape. According to the above-mentioned manufacturing method of the mattress 1, an appropriate adopted model number of each mattress unit 3a to 3c is determined according to the body shape of the user, and the mattress 1 is manufactured by using the corresponding mattress units 3a to 3c. Can be done. Therefore, it is possible to manufacture a mattress that can give a sleeping posture close to a natural body to each user having a different body shape without impairing the body pressure dispersibility in the lying posture. Further, according to this manufacturing method, it is possible to cope with the difference in body shape for each user only by combining the mattress units 3a to 3c of the adopted model number determined by the predetermined procedure, and the mattress 1 suitable for the user can be provided. It is easy to manufacture efficiently.

The measured head width Dh, shoulder width Ds, and buttock width Db will be described in more detail with respect to the process of step S1 described above. FIG. 6 is a front view of the user's upright posture, and is a conceptual diagram showing the head width Dh, the shoulder width Ds, and the buttocks width Db. In the present embodiment, the head width Dh is the horizontal distance between the user's both heads in the upright posture, and the shoulder width Ds is the horizontal distance between the user's shoulders in the upright posture, and the buttock width Db. Is the horizontal distance between the left and right ends of the user's buttocks in an upright posture.

The shoulder width in the lying position is narrower than the shoulder width in the standing position. Therefore, in order to approach the shoulder width when lying down in the lying position, two parallel plates are brought into vertical contact with both shoulders, and the two plates are narrowed with a force of about 100 N (shoulder narrowing). It is desirable to measure the shoulder width Ds in such a posture.

Regarding the process of step S2 described above, the shoulder weight Ws refers to the weight applied to the shoulder in the sleeping posture in the total weight of the user, and the buttocks weight Wb refers to the weight applied to the shoulder in the sleeping posture in the sleeping posture. It refers to the weight applied to the buttocks, and the leg weight Wf refers to the weight applied to the legs near the calves and heels in the sleeping posture among the total weight of the user. Each of these weights can be measured using, for example, four weight scales 100 to 103 as shown in FIG. In the case of this example, the measured value of the weight scale 101 supporting the shoulder of the user who takes a sleeping posture is the shoulder weight Ws, and the measured value of the weight scale 102 supporting the buttocks of the user is the buttocks weight Wb. The measured value of the weight scale 103 that supports the user's legs may be the leg weight Wf.

Although the weight of the head is not taken into consideration in the present embodiment, by providing the weight scale 100 that supports the head as shown in FIG. 7, the head weight Wh (in the sleeping posture among the total weight of the user) It is also possible to measure the weight on the head). This measurement can be used, for example, to determine the repulsive force of the pillow suitable for the user.

As described above, the information processing method performed by the information processing system according to the present embodiment is formed by using the first mattress unit 3a and the second mattress unit 3b to which different model numbers are assigned according to the repulsive force. , The first mattress unit 3a supports a part of the human body in a sleeping position in a state where the first part (corresponding to the "shoulder" in the present embodiment) is most submerged, and the second mattress unit 3b The first mattress unit 3a used for forming the mattress used by the user with respect to the mattress that supports the other part of the human body in the state where the second part (corresponding to the "buttock" in the present embodiment) is most submerged. It is an information processing method in which each of the model numbers of the second mattress unit 3b and the second mattress unit 3b is determined as the adopted model number.

And this information processing method is information that makes it possible to specify the difference between the vertical position of the first part and the second part of the user (corresponding to the information of "shoulder width Ds" and "butt width Db" in this embodiment). The difference between the user information acquisition step (corresponding to steps S1 to S3 in the present embodiment) for acquiring the user information UF including the user information UF and the vertical position specified by the user information UF (in the present embodiment, the "shoulder portion"). A determination step (corresponding to steps S6 to S12 in the present embodiment) for determining the adopted model number based on (corresponding to the protrusion distance between the buttocks Vsb) is included. According to the information processing method, it is possible to determine the adopted model number so that, for example, the user's sleeping posture is as horizontal as possible in consideration of the difference in the vertical position between the first part and the second part. It is easy to efficiently manufacture a mattress that can give a sleeping posture close to a natural body to each user having a different body shape such as shoulder width without impairing the body pressure dispersibility in the sleeping posture.

In this embodiment, consideration is given so that a user who takes a lying posture can be given a sleeping posture close to a natural body, but other sleeping postures (such as a supine or prone sleeping posture). It may be possible to give the user a sleeping posture close to the natural body. In this case, the first part and the second part may be appropriately defined according to the sleeping posture.
Further, as the information that makes it possible to specify the difference between the vertical position of the first part and the second part of the user, in addition to the form as in this embodiment, for example, the difference in the position such as the user's photo or video information. Various information related to can be adopted.

Further, the determination step is a target value of the subduction depth of the first portion in the first mattress unit 3a (“shoulder subduction depth DP1” in the present embodiment) when the user uses the mattress 1. A certain first target value (corresponding to "target shoulder subduction depth Ts" in this embodiment) and subduction depth of a second portion in the second mattress unit 3b (in this embodiment, "buttock subduction depth"). The difference between the second target value (corresponding to the “target buttock subduction depth Tb” in the present embodiment), which is the target value of the DP2 ”), coincides with the difference in the vertical position. (Refer to the above-mentioned "Equation 3" etc.). Further, in the determination step, the model number Us of the first mattress unit 3a, which is expected to have the subduction depth DP1 closest to the first target value, is determined to be the model number αUs adopted for the first mattress unit 3a, and the second part is described above. The model number Ub of the second mattress unit 3b, which is expected to have the subduction depth closest to the second target value, is determined to be the model number αUb adopted for the second mattress unit 3b. Therefore, it is possible to give a sleeping posture close to a natural body so that the sleeping posture is as horizontal as possible while setting each of the above target values so as not to impair the body pressure dispersibility in the sleeping posture.

Further, the user information includes a partial weight of the first portion of the user who takes a sleeping posture (“shoulder weight Ws” in the present embodiment) and a partial weight of the second portion (“buttock weight Wb” in the present embodiment). In the determination step, the adopted model number αUs is determined based on the first target value and the partial weight of the first part, and adopted based on the second target value and the partial weight of the second part. Determine the model number αUb. Therefore, it is possible to reflect the weight of each part of the user as accurately as possible in the process of determining the adopted model number, and to determine an appropriate adopted model number more accurately. For simplification of processing and the like, the simply obtained partial weight and the like may be adopted as the information of these partial weights. As an example, fixed values x and y are set in advance, x% of the total weight of the user (acquired as a part of the user information UF) is the partial weight of the first part, and y% is the part of the second part. It may be the weight.
