Programme-Controlled Sewing Machines TRIZ Cases
- Sewing Machine Auxiliary Motor Control for Fabric Feeding
Auxiliary motor and encoder decouple drive wheel from roller to prevent fabric deformation during thick material sewing.
- Sewing Machine Display Unit for Embroidery Positioning
A sewing machine display unit shows the embroidery frame and pattern images to help users grasp positional relations directly.
- Quilting Machine Thread Adjuster for Unthreading Prevention
An adjuster mechanism pulls a predetermined thread length from the looper to maintain stitch continuity during automated quilting operations.
- Sewing Machine Work Analyzing Device for Automatic Time Classification
The device calculates pitch time frequency distributions to automatically classify work times, enabling idle ratio analysis and identifying non-essential operations.
- Neural Network Garment Pattern Placement Automation
A neural network model predicts arrangement points for garment patterns to automate 3D avatar simulation.
- Sewing Machine Projector Calibration for Embroidery Accuracy
A sewing machine controller calibrates a projector to define a target area containing the guarantee zone using captured image coordinates.
- Tufting Pattern Yarn Balance via Needle Usage Graph
A pattern design engine generates a yarn usage graph per needle to balance pile height distribution.
- Sewing Machine Coordinate Data Creating Device for Hand-Drawn Aesthetic
A coordinate data creating device adds independent fluctuations to X and Y needle locations to generate new sewing patterns.
- Embroidery Sewing Machine Resume Position Selection
Embroidery sewing machine displays candidate needle positions on a transparent touchscreen for direct user selection.
- Ultrasonic Pen Interface for Sewing Machine Stitch Accuracy
An ultrasonic pen detects wave transmission to specify sewing parameters directly on fabric.
- Sewing Machine Projector for Tapering Pattern Positioning
A sewing machine controller projects a tapering pattern image onto the workpiece to guide needle bar and feed dog movement.
- Zigzag Sewing Machine Variable Adjustment Control
A zigzag sewing machine uses a control section to assign variable minimum adjustment units based on motor operation states.
- Sewing Machine Joystick Control for Free Motion Stitching
A sewing machine uses a tilting joystick to generate precise stitch data for free motion embroidery.
- Sewing Machine Needle Bar Thread Spool Replacement Display
Color-coded display portions indicate needle bar thread spool replacement status, reducing user operation complexity and identification errors.
- Variable Thread Consumption in Sewing Machine Cutters
Processor-controlled thread cutters adjust upper thread length within a predetermined interval to enable fine adjustments during sewing operations.
- Reciprocating Sewing Machines for Curtain Airbag Assembly
Dual sewing units move along a straight guide rail to process long curtain airbags, reducing installation space and boosting productivity.
- Sewing Machine Cutting Needle Rotation Mechanism
A sewing machine integrates a rotating cutting needle driven by a separate motor to perform independent trimming operations alongside standard stitching.
- Embroidery Quilting Apparatus Needle Drop Location Control
An automated examiner calculates exact needle drop coordinates to eliminate manual positioning delays and improve stitching accuracy.
- Sewing Machine Embroidery Pattern Positioning and Scaling
Automated sewing machine adjusts embroidery pattern position, orientation, and scale using selected reference points to eliminate manual retensioning.
