The specific embodiment
Fabric that is proposed and method provide has the fabric that can regulate surface area.
Fig. 2 A shows a preferred embodiment with the fabric 1 that can regulate surface area.Fabric 1 is formed by the textile fabric (not shown) that interweaves and at least one shape-memory alloy fibers 40.In Fig. 2 A, shape-memory alloy fibers 40 is included in the plane of fabric 1 according to the sine curve pattern.Shape-memory alloy fibers 40 serial or parallel connections are connected to current feedback circuit 100, perhaps addressing discriminably.Thereby current feedback circuit 100 is sent at least one shape-memory alloy fibers 40 with electric current causes its bending.Current feedback circuit 100 can be battery or is used to produce any other known devices of electric current.In addition, current feedback circuit 100 also can comprise the current regulator that is used to change electric current.In case at least one shape-memory alloy fibers 40 bends to the maximum of selection, this point may cater to the need.Prevented that like this shape-memory alloy fibers 40 from overbending taking place, and this overbending may cause destroying or it is invalid to use for a long time.In addition, current regulator can be used to control the surface area of fabric 1, for example is used for according to changing surface area with the corresponding pre-selected setting of the different magnitudes of current.In this configuration, the user can be provided with according to various electric currents and little by little change surface area.
Fig. 3 A shows the fabric 1 of Fig. 2 A, and at this moment current feedback circuit 100 stops to transmit electric current to arbitrary shape-memory alloy fibers 40.Each sweep of shape-memory alloy fibers 40 stretches.In this position, fabric 1 has the surface area bigger than the bending position shown in Fig. 2 A.Should be pointed out that Fig. 3 A is not an accurate Drawing in proportion, and the position of stretching do not need straightly fully, be in the slightly little bending of bending in the bending position but can comprise a large amount of ratios.
Fig. 4 B shows the shape-memory alloy fibers 40 that is in bending position (for example from current feedback circuit 100 received currents).In this position, the bending of shape-memory alloy fibers 40 makes textile fabric 60 move.So just the surface area with fabric 1 has reduced certain distance d.Textile fabric 60 is selected and/or be configured to by deflection, physically move or other position shifts gears and adapts with the change of shape-memory alloy fibers 40.For example, in Fig. 4 B, textile fabric 60 can be woven loosely so that make when current feedback circuit 100 transmits electric currents by shape-memory alloy fibers 40, makes more loose or tighter and and then the surface area of minimizing fabric 1 of braided structure thereby each fiber 60 moves their position in braided structure.In stretching position (being Fig. 4 A), textile fabric 6 is forced to separately, thereby has increased the surface area of fabric 1.Textile fabric 60 also can be formed by elastomeric material.
As attached example, shape-memory alloy fibers 40 can physically be connected to each textile fabric 60 and change to the effect of stretching the position so that strengthen from bending position.For example, this physical connection can comprise knotting or tie up or well-known adhesive in this area.If insulator is covered with shape-memory alloy fibers 40, then textile fabric 60 also can be attachable on the insulator.
Refer again to Figure 1A, the whole length of shape-memory alloy fibers 40 can be made up of many away minor segment of shape-memory alloy fibers, and wherein each away minor segment has slightly different angle of bend so that produce the sine curve pattern.Like this, when current feedback circuit 100 transmitted electric current by shape-memory alloy fibers 40, in response to same electric current, the bending of each section will be slightly different.For example, the α of first among Fig. 2 A can have first angle of bend (for example first bending position) that forms a sinusoidal part, and second portion β can have second angle of bend (for example second bending position) that forms opposite curvature.The sine curve pattern of the shape-memory alloy fibers 40 among Fig. 2 A so just is provided.
The many modification that have the configuration of Fig. 2 A.For example, Fig. 2 B shows the fabric 1 of the shape-memory alloy fibers 40 of level together with 50 braidings of vertical shape-memory alloy fibers.If current feedback circuit 100 is each shape-memory alloy fibers of addressing (promptly 40 and/or 50) individually, selectively vertical, the level of the surface area of fabric 1 or not only vertically but also flatly increased then is as shown in Fig. 3 B.
Fig. 2 C shows the fabric 1 that has according to the shape-memory alloy fibers 40 of fish-bone configuration.The section of marmem 40 is can be toward each other crooked, deviates from bending or crooked so that influence the surface area of fabric 1 when the received current according to any alternate manner each other.
The cross section of shape-memory alloy fibers 40 can be circle, ellipse or rectangle, respectively shown in Fig. 5 A, 5B and 5C.Fig. 5 A also shows the insulating barrier 400 around shape-memory alloy fibers 40 in addition.
Fig. 6 A shows a preferred embodiment of the clothing 100 with the shape of selectively regulating.Clothing 100 is a shirt.Clothing 100 comprises at least one variable partition 200,210,220.Variable partition comprises that at least one is woven in shape-memory alloy fibers among the textile fabric so that make at least one part 200,210,220 of clothing 100 to regulate.In the example of Fig. 1, clothing 1 comprises can be regulated collar 200, can regulate sleeve 210 and can regulate torso area 220.Each variable partition 200,210,220 is formed by at least one marmem, and this at least one marmem is regulated variable partition 200,210,220 surface areas when stretching the position changing to from bending position.The fabric that forms clothing 100 comprises textile fabric (not shown) and at least one shape-memory alloy fibers that interweaves.
In Fig. 6 A, shape-memory alloy fibers is introduced according to certain patterns, and this decides according to their positions in clothing 100.For example, the shape-memory alloy fibers in can regulating collar part 200 230 is formed in the plane of fabric 100 according to the sine curve pattern.The definite pattern of shape-memory alloy fibers 230 can be selected to and require corresponding with different variable partitions different.For example, the pattern of the marmem 230 in the sleeve variable partition 210 can be different from the pattern that can regulate in the collar part 200.Any part of the part that comprises appendage or wearer's body of clothing 100 all can comprise variable partition.In addition, the part that does not comprise appendage of clothing 100 also can comprise variable partition.In addition, a plurality of shape-memory alloy fibers can connect by serial or parallel connection.For example, clothing 100 comprises the regulated torso area 220 that the shape-memory alloy fibers by a plurality of parallel connections forms.
Be connected to current feedback circuit 250, perhaps addressing discriminably shape-memory alloy fibers 230 or series, parallel.Thereby current feedback circuit 250 is sent at least one shape-memory alloy fibers 230 with electric current causes its bending.Current feedback circuit 25 can be battery or is used to produce any other known devices of electric current.In addition, current feedback circuit 250 also can comprise the current regulator that is used to change electric current.In case at least one shape-memory alloy fibers 230 bends to the maximum of selection, this point may cater to the need.Prevented that like this shape-memory alloy fibers 230 from overbending taking place, and this overbending may cause destroying or it is invalid to use for a long time.In addition, current regulator can be used to control the adjustable region of fabric 1, for example is used for according to changing surface area with the corresponding pre-selected setting of the different magnitudes of current.In this configuration, the wearer of clothing 100 can little by little change variable partition 200,210,220 according to various electric current settings and required size.
Fig. 6 B shows an away minor segment of the clothing 100 of Fig. 6 A.When current feedback circuit 250 stops when for example being arranged in the shape-memory alloy fibers 230 that can regulate collar part 200 and transmitting electric currents, sweep will stretch as among Fig. 8.In the position shown in Fig. 8, the variable partition of clothing 100 has the surface area bigger than the bending position shown in Fig. 6 A.Should be pointed out that Fig. 8 is not an accurate Drawing in proportion, and the position of stretching do not need fully straightly, be in the slightly little bending of bending in the bending position but can comprise a large amount of ratios.
Shape-memory alloy fibers 230 can be selected to be had unidirectional or two-way memory effect.Under the situation of unidirectional memory effect, mechanically deform takes place in shape-memory alloy fibers 230, and is heated to distortion is returned once more by the shape-memory alloy fibers 230 after will being out of shape.The cooling of shape-memory alloy fibers 230 does not cause any other alteration of form.The temperature that shape-memory alloy fibers 230 distortion will surpass depends on the material character of its composition material.The clothing 100 that comprises the variable partition 200,210,220 with unidirectional memory effect shape-memory alloy fibers 230 can be used for shape and/or size are once regulated.For example, clothing can be produced in batches and sell according to single size.When having bought clothing, the wearer especially at least one variable partition 200,210,220 of heats laundry 100 so that obtain the irreversible size of required customization.So can place current feedback circuit 250.As an attached example, the material of formed shape memorial alloy fiber 230 can be selected to and makes wearer's body temperature can realize unidirectional distortion.Like this, in case the wearer tries on after the clothing 100, variable partition 200,210,220 will be regulated till the resistance of wearer's health overcomes mechanically deform.In this example, clothing 100 will be irreversibly carries out from customization with respect to wearer's health.
Under the situation of two-way memory effect, alternately heat shape-memory alloy fibers 230 and cause the generation distortion and eliminate distortion (for example, two of distortion states).For example, clothing 100 can comprise the variable partition 200,210,220 of the required size that reversibly is customized to the wearer separately.In this example, the single-piece clothing can be worn by a plurality of wearers and optionally regulate, and perhaps sets the such of defined according to presetting in the current feedback circuit 250 and regulates.
Fig. 8 B shows the shape-memory alloy fibers 230 that is in the bending position (for example from current feedback circuit 250 received currents).In this position, the bending of shape-memory alloy fibers 230 makes textile fabric 600 move.So just the surface area with the variable partition of clothing 100 has reduced certain distance d.Textile fabric 60 is selected and/or be configured to by deflection, physically move or other position shifts gears and adapts with the change of shape-memory alloy fibers 230.For example, in Fig. 8 B, textile fabric 600 can be woven loosely so that make when current feedback circuit 250 transmits electric currents by shape-memory alloy fibers 230, makes more loose or tighter and and then the surface area of minimizing fabric 1 of braided structure thereby each fiber 600 moves their position in braided structure.In stretching position (being Fig. 8 A), textile fabric 6 is forced to separately, thereby has increased the surface area of the variable partition of clothing 1.Textile fabric 600 also can be formed by elastomeric material.
As attached example, shape-memory alloy fibers 230 can physically be connected to each textile fabric 600 and change to the effect of stretching the position so that strengthen from bending position.For example, this physical connection can comprise knotting or tie up or well-known adhesive in this area.If insulator is covered with shape-memory alloy fibers 230, then textile fabric 600 also can be attachable on the insulator.
Refer again to Fig. 6 B, the whole length of shape-memory alloy fibers 230 can be made up of many away minor segment of shape-memory alloy fibers, and wherein each away minor segment has slightly different angle of bend so that produce the sine curve pattern.Like this, when current feedback circuit 250 transmitted electric current by shape-memory alloy fibers 230, in response to same electric current, the bending of each section will be slightly different.For example, the first among Fig. 6 B can have first angle of bend (for example first bending position) that forms a sinusoidal part, and second portion can have second angle of bend (for example second bending position) that forms opposite curvature.The sine curve pattern of the shape-memory alloy fibers 230 among Fig. 6 A so just is provided.
The many modification that have the configuration of Fig. 6 A.For example, Fig. 6 C shows the shape-memory alloy fibers 230 that the comprises level clothing 100 together with the variable partition of vertical shape-memory alloy fibers 330 braidings.If current feedback circuit 250 is each shape-memory alloy fibers of addressing (promptly 230 and/or 330) respectively, selectively vertical, the level of the surface area of the variable partition of clothing 100 or not only vertically but also flatly increased then, as shown in Figure 7.
Clothing has all forms and shape.For example, Fig. 9 shows the shirt 608 that comprises variable partition 200,210,220 and 610.Variable partition 200,210,220 and 610 sections of can regulating especially by certain pattern form, and these sections are configured for making clothing and wearer's the adaptive device of health together.For example, can regulate sleeve part and divide 210 to be formed by section 210a, 210b, 210c, wherein each can be by current feedback circuit 250 addressing and comprise at least one shape-memory alloy fibers 230 independently.Can regulate that sleeve part divides 210 can section 210a and 210b be little by little regulated by for example selecting only to regulate.As attached example, collar part 200 be can regulate and section 200a, 200b, 200c, 200d and 200e comprised, can regulate torso portion 220 and comprise section 220a, 220b, 220c, 220d and 220e, comprise section 610a, 610b and 610c and can regulate waist portions 610.The section of the addressing distinguished of any amount can form variable partition 200,210,220 and 610.
In addition, one group respectively the section of addressing can be affected according to the configuration of pre-selected.For example, for wearer A, can be programmed to so that only regulate the variable partition 200,210,220 and 610 that is arranged in section 200a, 200c, 200e, 210a, 220d, 220e and 610c current feedback circuit 250.The wearer can use the programmer that is included in the current feedback circuit 250 to exchange joint itself and programme.In addition, preset size can be programmed in the input current generator 250, so the wearer can select specific dimensions (i.e. trumpet, medium size, large size, extra large size) and corresponding section correspondingly to regulate.
Figure 21 shows by a preferred embodiment with clothing that the fabric 1 that can regulate surface profile forms.Fabric 1 is formed by the fabric (being part I) that comprises interweave textile fabric (not shown) and at least one shape-memory alloy fibers 2100.Figure 22 shows the enlarged drawing of the part I of Figure 21.In Figure 22, shape-memory alloy fibers 2100 is included in the plane of fabric according to spiral pattern.Be connected to current feedback circuit 250, perhaps addressing discriminably shape-memory alloy fibers 2100 or series, parallel.Thereby current feedback circuit 250 is sent at least one shape-memory alloy fibers 2100 with electric current causes its bending.According to the shape of spiral pattern, will cause like this to bend so that regulate the profile of the fabric of the outside, plane that remains flat part.
Figure 23 shows the side view of the Figure 22 when not having shape-memory alloy fibers 2100 received currents.In case current feedback circuit 250 transmits electric current to shape-memory alloy fibers 2100, just bends.Because shape-memory alloy fibers 2100 has spiral pattern, so just cause that zone 2101 raises to the outside on fabric plane, as shown in Figure 24.Shape-memory alloy fibers 2100 is woven among the textile fabric according to spiral pattern, so that make when received current them with bending and regulate the profile of fabric.
Fig. 6 shows the fabric 1 as current feedback circuit 25 Fig. 5 when shape-memory alloy fibers 40 transmits electric current.Some sweep at least of shape-memory alloy fibers 40 stretches.In this position, fabric 1 has compares the profile of regulating with bending position.Should be pointed out that Fig. 6 is not an accurate Drawing in proportion, and the position of stretching do not need fully straightly, be in the slightly little bending of bending in the bending position but can comprise a large amount of ratios.
Figure 25 shows the shape-memory alloy fibers 2100 that is in the bending position (for example from current feedback circuit 250 received currents).In this position, stretching of shape-memory alloy fibers 2100 makes textile fabric 2102 move.So just regulate the surface profile of fabric 1, produced the zone 2101 that raises.Textile fabric 2102 is selected and/or be configured to by deflection, physically move or other position shifts gears and adapts with the change of shape-memory alloy fibers 2100.For example, in Figure 25, textile fabric 2102 can be woven loosely so that make when current feedback circuit 250 transmits electric currents by shape-memory alloy fibers 2100, makes more loose or tighter and and then the surface area of minimizing fabric 1 of braided structure thereby each fiber 2102 moves their position in braided structure.In bending position (being Figure 25), textile fabric 2102 is moved, thereby has regulated the surface profile of fabric 1.Textile fabric 2102 also can be formed by elastomeric material.
