Definitions

  • the present invention relates to method and apparatus for producing custom manufactured items and has particular utility for producing individually tailored suits by cutting appropriately sized parts from a supply of fabric.
  • the garment industry has been slow in taking advantage of advances in technology to modernize its manufacturing operations.
  • the techniques utilized in fitting a suit vary in only minor aspects from the techniques used 50 years ago.
  • a person familiar with the suit making business in 1900 would not be unfamiliar with the techniques and machinery for producing suits in the 1980's.
  • the reluctance to change by the suit manufacturing industry has placed those manufacturers operating where labor costs are high at a distinct competitive disadvantage in relation to manufacturers who have less expensive sources of labor available.
  • This off-the-rack method of suit tailoring causes inefficiencies which add to the cost of the suit.
  • One inefficiency is the requirement that a large number of suits be stocked by the retail men's clothing store.
  • To increase the odds that each customer entering the clothing store will find an appropriate suit a wide variety of styles, patterns, and sizes must be on the rack so the customer may browse until he or she finds the right combination.
  • the store must carry multiple versions of the same suit for the more popular styles. The result is a high overhead in inventory for the clothing store.
  • a second inefficiency caused by the off-the-rack method of suit selection is a waste in cloth.
  • a man's suit will typically be made with a pair of pants which include enough material for a reasonably long legged individual, and in addition, will include enough material so that an individual can have cuffs added to the pants if he so desires.
  • the waste in cloth for satisfying the added length requirement when multiplied over the millions of suits produced in accordance with the off-the-rack retailing technique is tremendous.
  • An additional disadvantage is that the store clerk may not be able to determine when a particular customer simply cannot wear a given style suit.
  • the trained tailor could advise against a particular choice, but. the clerk may not recognize the difficulty and write up the order.
  • the tailor may or may not recognize the difficulty in this style selection. If the tailor recognizes that these measurements and this style are not compatible, the customer will receive no suit and will have to begin the process of suit selection again. If the tailor does not recognize these limitations, the suit will be tailored but will end up looking and fitting poorly.
  • a second procedure which has received much less acceptance by the suit buying public is a mail order procedure where the customer takes his own measurements and mails them to a mail order house which tailors the suit to fit those dimensions and sends back a finished suit.
  • This mail order technique has certain rather obvious deficiencies. The person taking the measurements is not trained so the measurements he provides the suit maker may be quite different from his actual measurements. If this is the case, the only remedy is to take the poorly fitted suit to a tailor who may or may not be able to remedy the problem.
  • the mail order procedure is also inefficient for the suit manufacturer.
  • the manufacturer receives the measurements from the purchaser and then must cut and sew that suit.
  • multiple numbers of identical suits can be produced.
  • each cut of each piece requires individual attention. While, the mail order suit purchasing procedure cuts down on inventory, the cost of manufacturing increases.
  • custom manufacturing of an item of apparel is accomplished by first measuring a customer's body size and shape as well as analyzing the customer's style preferences. These steps will typically be performed at a retail outlet for the manufacturer. This information will be used to modify the measurements for the item and in particular will be used in generating a relative positioning of a number of pattern points for the pieces which, when assembled, make up the item.
  • a first electronic measuring tape takes a length measurement using a measuring tape connected to a multi-turn potentiometer. As the user unwinds the tape the potentiometer turns and generates an analog output proportional to the length of tape unwound.
  • a user actuated button on the side of the tape causes the potentiometer output to be converted into a communications signal for transmission to a receiver.
  • a second measuring device includes both a mechanism for taking a length measurement and also a mechanism for computing an angle of the device with respect to a reference orientation.
  • the measuring mechanism is a set of calipers with one leg of the calipers coupled to a slide potentiometer that generates an analog output proportional to a length separation between the legs of the caliper.
  • a plumb bob pointer mounted to the device is coupled to a rotatable potentiometer so that as the pointer rotates the potentiometer yields an indication of the tilt of the device with respect to the vertical.
  • the means for storing the measurements preferably includes a video display for prompting the user as to a sequence in which the measurements are to be taken.
  • a measurement request is displayed on the screen, so that the person taking the measurements can position the measuring device in relation to a subject to take this measurement.
  • the user When the user is satisfied that the hand held unit is properly positioned, he'actuates a button which causes the length and in the second embodiment the angle measurement to be transmitted to the storage unit.
  • the invention has particular applicability to the manufacture of a custom tailored suit.
  • the pattern points define the shape of the pieces included in the suit. By knowing the relative positioning of these pattern points, the pieces can be cut from a roll of material along specified lines defined by the pattern points. A more detailed description of the concept of pattern points will be disclosed in conjunction with a preferred embodiment of the invention.
  • the one or more pieces making up the garment are cut by an automated cutting machine, preferably a laser cutter, and then sewn together to produce the suit.
  • the re-positioning of the pattern points is accomplished by a programmable controller such as a computer.
  • the computer generates control data which interfaces with a laser cutter controller so that during the cutting process the laser is cutting parts of custom made suits rather than the off-the-rack suits produced with prior art laser cutters.
  • the retail outlets suit inventory is reduced.
  • Various styles of suits will be included as well as various fabrics from which the customer can choose a suit, but the need for multiple suits of a given style as well as suits of every conceivable fabric are no longer necessary. Once a particular style and fabric suitable to the customer's needs is chosen, measurements are taken and used in manufacturing the suit.
  • the customer can order.more than the standard number of items to the suit.
  • An extra pair of pants with reversible vest to match that extra pair can be ordered and custom manufactured.
  • a large variety of materials and styles is also available with no additional expenditure of retail space or inventory. This flexibility in choice, it is believd, will enhance customer satisfaction.
  • the disclosed invention has applicability for all shapes or sizes of people including situations where large modifications of an off-the-rack garment would be required.
  • the measurements are taken, the pattern points generated, and the suit or other garment cut in exactly the same manner as a standard suit.
  • one object and advantage of the invention is a reduction in inventory and waste in the manufacture of items of apparel by implementing a made-to-measure manufacturing process utilizing an automated cutting mechanism controlled by a programmable controller.
  • Figure 1 illustrates a retail setting 10 where an individual is being measured for a garment by a store clerk using a hand held measuring device 12.
  • a storage unit 16 Supported on a table 14 is a storage unit 16 for storing measurements taken by the measuring device 12.

  • the particular device 12 shown in Figure 1 has a mechanism for taking both a length and an angle measurement.
  • a user positions the measuring device 12 so that two caliper arms 18, 20 are positioned to measure a desired length separation on a subject and then actuates a pushbutton switch 22 on the unit.
  • circuitry mounted inside. the device 12 generates an electrical output corresponding to this length and also determines an angle the device 12 makes with the vertical and generates an elec - trical output corresponding to this angle. These outputs are converted into signals suitable for transmission to the storage unit 16 and sequentially transmitted to that unit.
  • the storage unit 16 preferably comprises a personal computer having a keyboard input 24, a visual display monitor 26 and a printer 28.
  • the storage unit 16 also includes a central processing unit mounted to a motherboard as well as interface boards for coupling various inputs to the motherboard.
  • One interface board provides a coupling between the central processing unit on the motherboard and a floppy disk drive 30 which comprises one suitable mechanism for storing data from the hand held measuring device 12.
  • the storage unit 16 comprises an IBM (registered trademark) personal compu - ter with a hard disk drive 32 that allows rapid data storage as well as a more permanent means of storing that data.
  • the computer prompts the user as to the proper procedures to take in performing the various measurements the device 12 is capable of taking.
  • the operating system of the computer sequentially prompts via the display 26 the user as to which measurement is to be taken.
  • the user then reorients the measuring device 12 to take the particular measurement and actuates the pushbutton 22 so that a length and angle measurement are automatically transmitted to the computer 16.
  • FIG. 8 An alternate hand held unit 34 is illustrated in Figures 8 and 9.
  • This unit 34 is strictly a measuring device for performing length measurements along a straight, curved, or zig-zagging direction. The user must therefore distinguish when a prompt appears on a screen 26 as to which of the two units 12 or 34 is to be used in taking a measurement.
  • Each unit includes its own transmitter portion (to be described), whereas the storage unit 16 includes a single receiver-responsive to transmissions from either of the two hand held units 12, 34.
  • FIG. 1 shows how two caliper arms 18,20 take a length measurement.
  • a first of the two caliper arms 18 is fixed in relation to the measuring device 12 and extends at approximately right angles away from a ruler 42 which extends the length of the measuring device 12.
  • a second of the caliper arms 20 is slidably mounted to the ruler 42 and its position can be adjusted so that the two arms 18,20 are separated by a particular length L of interest.
  • the two arms 18,20 have been manually positioned so that the separation between the neck and chest is measured.
  • the user positions the device 12, adjusts the arm separation, and actuates the pushbutton 22.
  • a manual measurement may also be taken by noting the separation distance between the arms.
  • a contoured end piece 44 similar in shape to the arm support on a crutch.
  • the end piece.44 is positioned under the subject's arm and the movable or adjustable caliper arm 20 is moved along the ruler 42 until it is positioned next to the subject's hand where a coat sleeve would end. The user then actuates the button 22 and this measurement is automatically transmitted to the storage unit 16.
  • a neck piece 46 that couples the ruler 42 to a handle 48 which the user grasps while positioning the measuring device 12.
  • a protractor 51 including visible angle markings and a pivotally mounted pointer 53 for obtaining an angle measurement.
  • the pointer 53 is free to pivot thereby providing an indication of the device's orientation with respect to the vertical. These angles can be helpful in determining the posture of the subject.
  • Figure 1 when determining the length between the neck and chest.position the pointer 53 pivots away from its, position shown in Figure 9 to yield an indication of the angle between the vertical and the orientation of the device 12.
  • this angle measurement is also transmitted when the user actuates the pushbutton 22.
  • the riser can also take a manual reading in the event the transmitter malfunctions by observing the pointer position with respect to the angle markings on the protractor.
  • the protractor 51 and ruler 42 are separated by a gap 55 to allow the slidable caliper arm 20 to move continuously from a position next to the stationary arm 18 to the extreme opposite end of the ruler 42 next to the end piece 44.
  • Each of the caliper arms 18, 20 serves as a mount for one of two cross pieces 57, 59.
  • the cross pieces can either be positioned to aid in the length measurement or can be removed so that only the arms 18, 20 extend away from the ruler 42.
  • the two cross pieces are shown in place but, for example, if the sleeve length were being measured, the cross pieces would be removed and only the caliper arms 18, 20 would be relied upon in positioning the device 12.

  • the notch 67 and finger 63 in combination position the cross piece along one degree of linear movement and the two triangular guides 65 define the position of the cross piece in a perpendicular or orthogonal direction. The mating between cross piece and caliper arm is maintained by an interference fit between the two.
  • Figures 6 and 7 show details of the coaction between the movable caliper arm 20 and the ruler 42.
  • the caliper arm 20 defines a through passage for the ruler 42 and includes a ridge or tongue 71 which mates with a groove defined by the ruler 42. Coupled to the caliper arm 20 are-a pair of electrical contacts 73, 75 which ride against the ridge 71 extending along the length of the ruler 42. These electrical contacts 73, 75 provide an indication of the position of a movable caliper arm 20 in relation to the ruler 42.
  • the ridge 71 comprises two metallic elements separated by an insulator.
  • One metallic element has a very low resistance and provides a ground for one of the contacts 75.
  • a second metallic element has a uniform resistance per unit length and serves as a strip potentiometer.

If the answer to this question is no, a rejection flag 122 is set and saved 124 on the floppy disk storage unit 30. A customer data disk 126 has been schematically illustrated in Figure 3 to indicate a permanent record of this rejection is maintained at the store 10. If a fit is possible, an acceptance flag is set 128 and in a similiar fashion, this information is stored on the floppy disk 126.
  • the information is stored regardless of whether a fit is possible. A file is therefore created for each customer whose.measurements are taken utilizing the hand held measuring device 12. This information is sent to the manufacturer and can be accessed as needed.
  • the rejection data can be useful in the business planning of the garment manufacturer. If enough people need a particular modification to a given style and that modification cannot be accommodated by the disclosed process, it behooves the manufacturer to create that style or allow an existing style to be modified to meet the customer's needs. Thus, if a significant percentage of customers are-rejected for the same reason after selecting a particular style, modifications can be made in the style to accommodate those customers.
  • the computer 16 next prints 130 the customer data and invoice information. This printing step involves separate generation of a customer data report 132 and generation of a customer in-store invoice 134.
  • a communications link (not shown) between the store computer 16 and a factory computer is maintained either along a dedicated link-up or alternately over the public telephone system with the use of a modem.
  • the factory computer is responsible for generating a control tape used by a separate factory computer 138 ( Figure 8) in controlling a laser cutter' 139.
  • the factory computer begins 'the process of generating a control tape by retrieving customer information at a step 140 in Figure 4A.
  • customer data from the floppy disk 126 at the store location is transmitted to the factory computer and this information is transmitted at a step 142 to a customer file 144 maintained on a hard disk unit forming part of the factory computer system.
  • This algorithm utilizes model specifications stored on a disk 148 to make a determination 150 regarding the best model fit for a customer's body type.
  • the computer compares the model specifications with the customer measurements to determine alterations in the model specifications to fit the particular customer. This alteration or delta information is stored on the customer order file 144.
  • the computer prints 154 an interpretation report 156 for future reference.
  • Figure 4B schematically illustrates the steps in modifying the pattern points based upon the interpretation process 62.
  • the pattern is altered before any laser cutting can be performed.
  • Each garment includes a number of different patterns which are sewn together to produce that garment.
  • the reference or pattern points are stored on a pattern file 160 which are repeatedly accessed by the computer in modifying the pattern points.
  • a first pattern is taken to size 162 and a number of pattern points altered 164 until a determination 166 is made all pattern points for a particular pattern have been altered. Details of this alteration process for one pattern, the back piece for a man's suit, are described below in conjunction with Figures 6A and 6 B .
  • the computer loads 168 the altered pattern points for a particular pattern into a marker file 170.
  • a test 172 is made whether all patterns for a particular garment have been adjusted. If all garments have been adjusted, a routing sheet 174 for that garment is printed 176. If all patterns have not been modified, the computer returns to the beginning 162 to access the next set of pattern points from the pattern file 160.
  • the modified patterns stored in the marker file 170 are utilized to layout 178 the garment on a cathode ray tube.
  • This layout corresponds to pattern arrangement from a web of material.
  • the process of building these markers 178 involves an operator sitting in front of a cathode ray tube and moving the patterns for a particular garment to a screen area that represents the material.- As the operator arranges the patterns the arrangement is stored by the computer and used to generate a control tape for the laser cutter 139. Alternately, the process of marker generation can be accomplished automatically by a computer program.
  • Figure 4C summarizes bookkeeping steps that must be performed prior to laser cutting.
  • a plan or order 180 of cutting must be determined.
  • a determination must also be made concerning the amount of materials required by the laser cutter.
  • This determination 182 utilizes a material file 184 and results in the printing 186 of a material requirements report 188.
  • a control tape 192 for the computer 138 to control laser cutting of a number of garments.
  • a materials cut plan report 196 is generated indicating the sequence and timing of laser cutting.
  • a laser cutting station 194 is illustrated in Figure 8.
  • a roll 195 of fabric 197 is unwound and moved by a conveyor 198 beneath the laser cutting 139 at a controlled rate.
  • the computer 138 responds to the control tape 192 and directs the cutter 139 to cut patterns from the fabric 197.
  • Subsequent to laser cutting of the fabric a number of manufacturing steps ( Figures 4D and 4E) are monitored and controlled. Prior to discussing these steps, however, details of the interpretation process 150 and pattern alteration process 164 are described.
  • a first interpreter step 210 the computer accesses model specifications stored on a disk storage 148.
  • the interpreter determines 212 what size the customer needs based upon the measurements and adds or subtracts 214 increments to the master model specifications stored on disk 148. This addition or subtraction is required for a suit, for example, if the customer measurements call for anything other than a size 40 regular.
  • minimum and maximum values are determined for each of the measurements for the particular size the customer needs. Also at this step an ideal value for each measurement is determined.
  • a customer ease is added to a particular customer measurement. This ease factor is the amount a customer measurement must be incremented to give the ideal garment measurement.
  • the customer ease measurement is compared 220 to the model minimum and maximum values. If the customer measurement including ease' is within the minimum or maximum value, the garment need not be altered based upon this measurement. Each measurement in turn is compared in this way until all measurements have been compared with the minimum and maximum values.
  • an alteration delta is generated 224 and this delta factor is compared 226 with alteration limits. If this change or delta is within limits, this alteration delta is stored 228 in memory 229. If it is not within limits, the alteration change is modified 230 to be within the alteration limits and then stored 228. Eventually, either each measurement will have been seen to be within the minimum and maximum value and therefore no change in that measurement is needed or an alteration delta will be generated for that particular measurement.
  • specifications for a different model are accessed 210 by the interpreter and the same process performed for each of the measurements for that.particular model.
  • four different models are analyzed for.each style. One of these models produces the best fit for that customer's measurements.' The model that produces that best fit is used to manufacture the garment. The customer knows that the suit corresponds to a particular style but does not know which model among the four possible choices for a particular style the computer will choose in matching his or her style preferences with his or her unique measurements. The optimum model choice depends on how many measurements are beyond the minimum/maximum values as well as the size of the alteration deltas generated for each of the multiple models.
  • FIG. 6A, 6B and 7 the modification or alteration 164 of the reference points for a particular pattern will be discussed in conjunction with a specific example. This process takes place after a particular garment model has been choosen.
  • the specific example discussed is the modification of the back pattern 310 ( Figure 7) for a man's suit based upon variations from a normal neck dimension.
  • a point reference array 352 is initialized 312.
  • Each of approximately seventy points that define the back pattern 310 has an entry in a point attribute array 314 which tells what position in the point reference array that point occupies. This position is extracted 316 so that the point reference array is filled with the reference numbers of each of the seventy points.
  • Each pattern has a ten digit pattern number 320 with the last three digits corresponding to a part number.
  • the part number can refer to either the cloth back (pattern 011).or one of two (patterns 001, 002) linings for the back. Based upon this part number, certain critical points of the pattern are defined and extracted 353 from the point reference array 352.
  • a pattern co-ordinate array 362 stores the X and Y co-ordinates for each of the points which define a particular pattern and size. Stated another way, the backpiece for a 44 normal (for example) has 70 pattern points to define the backpiece of Figure 7. The X-Y co-ordinates for these 70 points is stored in the pattern co-ordinate array.
  • the Figure 6A algorithm saves 364 the neck and shoulder point co-ordinates by ascertaining the position of these points from the point reference array 352 and then changes 366 the Y co-ordinate (see Figure 7) of each of the pattern points between the neck point and the shoulder point inclusive by an alteration or delta factor 368 based upon the subject's neck dimension. This results in a shift to the right (small neck) or left (large neck) of the curve 369 between the shoulder 356 and neck point 358. These altered point co-ordinates are saved in the pattern co-ordinate array 362.
  • a parameter array is then filled 370 from the co- ordinants of the points defining the old neck hole curve 372 and the new and old end points 358, 360 for the neck hole curve.
  • a reshaping subroutine 374 reshapes the neck hole 372 and fills in co-ordinates for the new pattern into the parameter array. This reshaping is based upon an approximation method using derivatives (slopes) of the old curve and the new or altered endpoints.
  • the parameter array co-ordinates are transferred 375 back to the pattern array 362 and define the altered pattern.
  • the co-ordinates for the original armhole curve 376, and the end points 354, 356 for the new and old armhole curve are entered 378.into the parameter array and the reshaping subroutine 374 modifies the co-ordinate points along the armhole 376.
  • the new armhole co-ordinates are transferred 380 from the parameter array to the pattern array 362.
  • a modification in the back based upon neck size is complete and the computer goes on to make modifications based upon other measurements for other patterns until the. pattern points for the entire garment have been altered.
  • This data is all stored and is represented by the patterns presented to the CRT operator who builds 178 the material cut arrangements. The altered patterns then, of course, become embodied in the computer control tape 192.
  • Figures 4D and 4E schematically illustrates post- laser cutting procedures utilized in the automated garment manufacturing process.
  • a number of garment pieces have been cut using the laser cutter and these pieces are ticketed or marked 410 and sent 412 to appropriate locations for sewing.
  • Routing sheets 174 are.generated to indicate-the particular . path a garment pattern must follow.
  • the routing sheets 174 contain control data used in the manufacture of the garment. This control data is used to insure the proper and precise assembly of the garment since each garment is unique and requires different handling during assembly.
  • the control data is any information needed for the precise assembly of a garment. This data can be anything as specific as the proper positioning of a pocket or button to something as general as whether or not to edge stitch the lapel or a specific way the finished garment needs to be pressed.
  • the control data also includes finished dimensions of the garment. These dimensions are used for quality control during the various phases of the manufacturing process.
  • This control data can be in either a printed form for manual assembly or in a numeric control form for automated assembly.
  • each of the parts or patterns goes to its respective sewing shops where parts are sewn together and sent to a stockroom ( Figure 4E) where all the garment components (jacket, pants, vest, etc) are matched 434 together. The garment is then shipped 437 back to the store and delivered 438 to the customer.
  • the term precision is used. This term is required in the fabrication process since'it would be counter productive for the precision alteration of the various pattern points to be performed under computer control, first in the generation of the control tape and secondly in the laser cutting and then lose this precision by sloppy sewing at the sew shops. If the suit or other garment is made to fit the customer with the aid of the computer, the sewing steps 424, 428, 429 must be precisely carried out with the highest standards of quality control maintained.
  • the generation 435 of a daily shipping list is in conformity with the automated steps described above.
  • that subject is promised a suit on a given delivery day which is coordinated with the back log of orders at the factory.
  • the shipping list generated at the stage 435 after the garment components have been assembled in the stockroom, is based upon that earlier order information and unless production has fallen behind for a legitimate reason the two dates should match.
  • the disclosed invention has been described with a degree of particularity.
  • the choice of computer system and measuring devices for both retail and factory locations is based upon the memory and storage requirements of the manufacturing system. As business needs dictate, this computer system choice can be modified.
  • the manufacturing process need not be limited to a men's suit although certain ones of the manufacturing steps have obviously been described in relation to a man's suit. It is the intent therefore that all alterations and/or modifications falling within the spirit or scope of the appended claims be protected.
