Knitting TRIZ Cases

Amorphous alloy injection molding replaces stamping and bending to make warp knitting needles stronger, tougher, and longer lasting.

Using amorphous alloy injection molding, this warp knitting needle improves fatigue strength and wear resistance while simplifying production.

During doffing, successive fabric images and encoder pulses identify abnormal needle positions for targeted correction and less waste.

A varying center-of-gravity line creates self-cleaning motion in knitting tools, reducing friction, dirt accumulation, and wear.

A compound needle uses a foot extension reaching under the slider channel base to secure the intermediate wall element.

Segmented waste discharge paths in a compound needle prevent slider groove accumulation while maintaining structural strength against breakage.

A latch needle design with a head width below 95% of the shank reduces mechanical wear and prevents thread damage during textile production.

A design system corrects stitch size based on sample aspect ratios to determine knitting courses for target dimensions.

Perpendicular arcuate sawslot end surfaces prevent dirt accumulation and ensure secure latch closing in textile machines.

A knitting method allocator assigns intarsia jacquard or intarsia techniques to specific fabric areas based on pattern shape and width.

Dynamic sinker positioning resolves the trade-off between simple fixed structures and reliable stitch stripping by reducing needle latch wear.

A latch needle pivot pin uses a non-round cross-section to create a form fit that prevents twisting.

Actuated flexible laminas on a knitting needle enable precise stitch transfer while reducing stress on components in high-fineness machines.

A direct injection lubrication system uses pulse and spray modes to deliver oil precisely.

Elastic deformation of the joining part secures the connection while eliminating complex post-processing steps required for strong fixation.

Reduced edge thickness on compound needle side walls enables small bending radii for stable slide guidance without increasing manufacturing forces.

A flat knitting design device displays compressed and non-compressed symbol representations for pattern editing.
