Window Lifter Cable Holder for Parallelogram Guide Rail Noise Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window lifters with 'X' configurations experience noise due to cable transverse movement when the vehicle door is closed, which affects user comfort and perceived vehicle quality, and current solutions like retaining clips complicate assembly.
Innovation Solution
A window lifter design featuring guide rails that form a parallelogram shape with a cable holder to fasten the cable between corresponding ends, reducing lateral displacement and eliminating the need for additional fastening means, thus simplifying assembly and reducing noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a retaining clip is used to prevent cable transverse movement, then cable stability is improved, but assembly complexity increases
Solution Approach 1:
The holder integrates both the cable fastening function and the transverse movement prevention function into a single component. The holder is attached to the guide rail and simultaneously secures the cable while preventing its transverse displacement, eliminating the need for a separate retaining clip and simplifying the assembly process.
Solution Approach 2:
The holder serves multiple functions: it fastens the cable to the guide rail structure and prevents the cable from moving transversely during door closure. This multi-functional design replaces what would traditionally require multiple separate components, reducing assembly complexity while maintaining cable stability.
2Ease of manufacture
If the cable is left unfastened between guide rails, then assembly is simplified, but noise is generated due to cable transverse movement
Solution Approach 1:
The holder combines the cable attachment and transverse movement prevention into a single integrated component that is directly mounted on the guide rail. This allows the cable to be secured without requiring additional fastening elements, maintaining assembly simplicity while preventing noise-generating cable movement during door closure.
3Stability of the object's composition
If additional fastening means are added to secure the cable, then cable transverse movement is limited, but device complexity increases
Solution Approach 1:
The holder integrates the cable fastening function and the transverse movement prevention function into a single component. The holder is attached to the guide rail and simultaneously secures the cable while preventing its transverse displacement, eliminating the need for a separate retaining clip and simplifying the assembly process.
Solution Approach 2:
The holder serves multiple functions: it fastens the cable to the guide rail structure and prevents the cable from moving transversely during door closure. This multi-functional design replaces what would traditionally require multiple separate components, reducing assembly complexity while maintaining cable stability.
