Programme-Controlled Sewing Machines TRIZ Cases
- Sewing Machine Cam Mechanism for Stable Cutting Needle Rotation
Dynamic gap adjustment compensates for dimensional variations to ensure stable and automatic cutting needle rotation.
- Tufting Machine Backing Shifting for Sew-Through Reduction
A shiftable backing feed adjusts lateral needle positioning during tufting to optimize stitch placement and minimize over-sewing.
- Applique Data Management Preventing Stitch Overlap
An applique data management system identifies inner and outer contours to prevent stitch overlap.
- Embroidery Data Creation Using Local Angle Thresholds
A method calculates angle characteristics for pixels based on intensity thresholds to arrange line segments for unique embroidered textures.
- Tufting Machine Yarn Feed Control for Uniform Consumption
A programmable control system manages independent yarn feed profiles to ensure uniform consumption across different tufted carpet stitches.
- Sewing Machine Wireless Operational Code Transmission
Sewing machine transmits operational codes to a terminal device, displaying real-time instructions and next options without manual searching.
- Sewing Machine Speed Control for Free Motion Stitching
A sewing machine controller adjusts motor speed based on consumed needle thread and stitch pitch to enable smooth free motion operation.
- Sewing Machine Dynamic Thread Allocation via Error Notification
A sewing machine processor allocates upper thread data sets to needle bars and notifies users of change-eligible bars.
- Embroidery Data Creation Adjusting Needle Drop Density
Embroidery data creation apparatus adjusts needle drop point density by modifying turning point coordinates based on contour length differences.
- Sewing Machine Dynamic Sampling for Stitch Pitch Control
A sewing machine control device adjusts optical sensor sampling periods based on workpiece movement speed to maintain constant stitch pitch.
- Sewing Machine Camera Vision System for Embroidery Alignment
Camera vision system tiles scanned fabric images to compensate for geometrical distortion and light variations, enabling precise embroidery positioning.
- Sewing Machine Cutting Needle Dynamic Spacing Control
A sewing machine adjusts cutting needle spacing based on detected cloth thickness to optimize cut data.
- Sewing System Needle Center Calibration via Image Processing
A sewing system uses a camera and controller to calibrate the needle center position through automated image processing of stitch positions.
