Vehicle Seat Adjustment Device with Direct Brake Ring Welding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle seat adjustment devices with frictional locking mechanisms are cumbersome and increase the weight and cost of the seat, while also occupying more transverse installation space due to the need for adapters and complex structures.
Innovation Solution
The brake ring is directly welded or glued to the seat frame, eliminating the need for adapters and integrating the adjustment device into the seat structure, reducing weight and space requirements, and utilizing an open brake ring design for a sealed interior and a locking mechanism with rollers for secure adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adapters or connecting plates are used to fasten the adjustment device to the seat frame, then the adjustment device can be securely mounted, but the weight and cost of the vehicle seat increase
Solution Approach 1:
The brake ring is directly welded or glued to the seat frame, merging the fastening function into the existing components. This eliminates the need for separate adapters or connecting plates, thereby reducing weight and cost while maintaining secure mounting through direct structural integration.
Solution Approach 2:
The patent removes the unnecessary intermediate components (adapters and connecting plates) from the assembly. By extracting these redundant elements and using direct welding or gluing of the brake ring to the seat frame, the solution simplifies the structure and reduces weight while preserving the essential mounting function.
2Reliability
If adapters or connecting plates are used to fasten the adjustment device, then secure mounting is achieved, but the cost of the vehicle seat increases
Solution Approach 1:
The brake ring is directly welded or glued to the seat frame, merging the fastening function into the existing components. This eliminates the need for separate adapters or connecting plates, thereby reducing weight and cost while maintaining secure mounting through direct structural integration.
Solution Approach 2:
The patent removes the unnecessary intermediate components (adapters and connecting plates) from the assembly. By extracting these redundant elements and using direct welding or gluing of the brake ring to the seat frame, the solution simplifies the structure and reduces cost while preserving the essential mounting function.
3Reliability
If a closed brake ring design is used to seal the interior space, then sealing is improved, but the device complexity increases
Solution Approach 1:
Instead of using a closed brake ring design to achieve sealing, the patent inverts the approach by using an open brake ring design. The sealing function is achieved not through the brake ring's closure but through the natural containment provided by the adjustment device housing and component arrangement, thereby reducing complexity while maintaining sealing effectiveness.
4Reliability
If adapters and connecting plates are used for fastening, then secure mounting is achieved, but the transverse installation space increases
Solution Approach 1:
The brake ring is directly welded or glued to the seat frame, merging the fastening function into the existing components. This eliminates the need for separate adapters or connecting plates, thereby reducing weight and cost while maintaining secure mounting through direct structural integration.
Solution Approach 2:
The patent removes the unnecessary intermediate components (adapters and connecting plates) from the assembly. By extracting these redundant elements and using direct welding or gluing of the brake ring to the seat frame, the solution simplifies the structure and reduces transverse installation space while preserving the essential mounting function.
