Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing textile processing machine clothing strips are expensive to produce, prone to inaccuracies due to wear and tear, and require complex regrinding processes, with limited flexibility and high rework, leading to difficulties in maintaining precise tolerances and efficient assembly.
Innovation Solution
The clothing strip is composed of toothed segments connected via integral bonding methods like laser or inert gas welding, with a metal strip for flexible attachment to the flat bar, allowing for precise alignment and easy regrinding without disassembling the flat bar, and featuring a magnetic connection for secure and adjustable fitting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If flexible assemblies are used on cover bars, then the carding gaps can be maintained, but the manufacturing cost increases and regrinding potential is limited
Solution Approach 1:
The flexible assembly is divided into individual wire segments that can be independently replaced. Each wire is separated and can be individually ground and reinstalled, eliminating the need to replace entire expensive flexible assemblies while maintaining carding gap precision.
Solution Approach 2:
Instead of discarding entire flexible assemblies after limited use, the invention allows individual wires to be recovered, ground, and reused multiple times. This extends the service life of the valuable wire material while maintaining performance.
2Manufacturing precision
If entire cover bars are disassembled for regrinding, then tolerance accuracy of less than 0.1 mm can be achieved, but production time increases
Solution Approach 1:
The cover bar assembly is segmented into removable wire components. Only the individual wires need to be removed for regrinding, not the entire cover bar structure. This reduces the time required while maintaining the ability to achieve tight tolerances on the wire tips.
Solution Approach 2:
Wires are pre-positioned in the cover bar with precise spacing and orientation. This preliminary arrangement allows for quick removal and reinstallation after grinding, eliminating the need for time-consuming realignment procedures while maintaining sub-0.1mm tolerance accuracy.
3Adaptability or versatility
If hooks are inserted into fabric core, then flexible assemblies can be attached, but the number of refinishings is limited and the process is time-consuming
Solution Approach 1:
The mechanical hook insertion system is replaced with a direct wire mounting system that uses adhesive or friction fit. This eliminates the limitation of hook durability and allows wires to be quickly replaced multiple times without degrading the attachment mechanism, significantly increasing refinishing frequency.
4Strength
If welds are applied across entire surface, then connection strength increases, but post-grinding rework increases to achieve flat contour
Solution Approach 1:
Instead of applying welds across the entire wire surface, welding is concentrated at specific localized areas such as the base of the wire or at discrete points. This provides sufficient connection strength while leaving the majority of the wire surface untouched, eliminating the need for extensive post-grinding rework to achieve a flat contour.
