Spool-Pin Assemblies TRIZ Cases
- Horizontal-Axis Bobbin Output Structure to Prevent Thread Twisting
A horizontal-axis bobbin lets sewing thread unwind naturally, reducing twisting, shear stress, breakage, and unstitched products.
- Motor-Driven Thread Tension Apparatus for Sewing Machines
Replacing mechanical friction with an electric motor and controller, this apparatus resolves tangling caused by varying machine speeds.
- Spool Rest Thread Path Inversion for Sewing Machine Stability
Inverting the thread path via a polygonal spool rest prevents unwinding and entanglement of thick sewing threads.
- Sewing Machine Thread Guide Partition Wall
Partition wall member prevents thread entanglement with tensioner during high-speed sewing operations.
- Modular Thread Spool Base for Sewing Machines
Segmented thread spool bases reduce physical footprint by allowing users to attach only required pins.
