Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening systems for compaction modules on spinning machines require additional extraction tubes and struggle with precise positioning, leading to inefficiencies and the need for special sealing elements.
Innovation Solution
A fastening mechanism with clamping elements and a coupling device that allows for quick and exact installation of the compaction module on drafting units, using a clamping element with retaining sections and slots for secure positioning and pivot movement, and a sealing mechanism to connect the suction channel to a suction tube without additional extraction channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a U-shaped end piece is used to slide the carrier onto the suction tube, then the compaction module can be positioned on the spinning machine, but additional extraction tubes and special sealing elements are required
Solution Approach 1:
The patent combines the fastening function and the suction function into a single integrated clamping element. The clamping element directly engages with the suction channel outlet, eliminating the need for separate extraction tubes and sealing elements. This merging of functions resolves the technical contradiction by simplifying the system while maintaining ease of operation.
Solution Approach 2:
The clamping element serves multiple functions simultaneously: it provides mechanical fastening of the carrier to the spinning machine and creates the suction connection through its integrated suction opening. This multi-functionality eliminates the need for additional specialized components, resolving the contradiction between operational ease and system complexity.
2Manufacturing precision
If additional guides are installed on the suction tube for precise positioning, then the carrier can be exactly positioned, but the device complexity increases
Solution Approach 1:
The clamping element features an asymmetric design with a single open receiving slot that guides the retaining element during insertion. This asymmetric geometry provides automatic alignment and precise positioning without requiring additional symmetric guiding structures on the suction tube, thereby achieving positioning precision without increased complexity.
Solution Approach 2:
The clamping element's receiving slot is designed to automatically guide and position the retaining element during the insertion process. The slot's geometry self-aligns the components, providing precise positioning through the fastening mechanism itself rather than requiring separate guiding systems, thus resolving the contradiction between precision and complexity.
3Reliability
If special sealing elements are installed to seal the suction channel, then vacuum conditions are maintained, but the ease of installation and removal is reduced
Solution Approach 1:
The clamping element incorporates a flexible sealing lip or film at its suction opening that automatically seals against the carrier's suction channel outlet. This flexible sealing mechanism maintains reliable vacuum conditions while allowing easy insertion and removal of the carrier, as the flexible seal deforms during assembly and disassembly without requiring complex sealing structures.
Solution Approach 2:
The sealing function is integrated into the clamping element itself, which automatically creates the seal through its own structural features during the fastening process. The clamping element's design includes self-sealing characteristics that maintain vacuum reliability without requiring separate sealing components, thereby preserving ease of installation and removal while ensuring reliable sealing.
