Leather Sewing TRIZ Cases
- 3D Component Stitching Head for Single-Side Complex Trim Sewing
A synchronized looper and needle-bar setup stitches 3D trim from one side, reaching corners and small radii with lower labor and cost.
- Illuminated Visible Seam Structure for Uniform Thread Lighting
Light is coupled into stitched upper thread portions to create a uniformly illuminated visible seam while blocking direct glare from below.
- 3D Trim Stitching Head for Small Radii and Sharp Corners
A narrow-post stitching head places true stitches on 3D automotive trim, reaching small radii and sharp corners without cut-n-sew.
- Oscillating Sewing Arm and Bushing Layout for Tubular Articles
An oscillating arm and stabilized bushing layout lets sewing machines stitch tubular and complex articles without arm interference.
- Modular Sewing Machine Base with Universal Coupling
Universal coupling mechanisms in a modular sewing machine base reduce unique part counts and manufacturing costs.
- Ultrasonic Stitching of Composite Fan Blades
Ultrasonic stitching joins composite fan blade layers via vibration fusion, preventing delamination under shear strain while preserving material integrity.
