Seat Track Sensor Assembly With Adjustable Tooth-Lock Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle seat track position sensors face challenges in secure mounting due to variations in dimensions and tolerances of seat tracks and their hollow interior cavities, leading to inconsistent and unreliable attachment.
Innovation Solution
A vehicle seat track position sensor assembly with a bracket featuring interlocking teeth, flanges, and locking tabs that securely engage with the seat track, allowing for adjustable and secure mounting by advancing teeth and using guide rails and fins to accommodate varying dimensions and tolerances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed mounting bracket is used for the sensor assembly, then the mounting structure is simple, but it cannot accommodate variations in seat track dimensions and tolerances
Solution Approach 1:
The bracket incorporates movable adjustment mechanisms including sliding components and telescoping elements that allow the bracket to dynamically adapt its dimensions to match variations in seat track cavity sizes, transforming a static structure into a dynamic one that can accommodate tolerance ranges
Solution Approach 2:
The bracket design includes adjustable parameters such as variable arm lengths, reconfigurable mounting positions, and adaptable engagement point locations that can be modified to match different seat track dimensions, allowing the same bracket to fit multiple track variations
2Stability of the object's composition
If the sensor assembly is made rigid to prevent movement, then positioning stability is improved, but it becomes difficult to accommodate different seat track sizes
Solution Approach 1:
The bracket employs dynamic adjustment mechanisms that allow for stable positioning once adjusted, while the adjustment capability itself enables adaptation to different track sizes, resolving the contradiction between rigidity and adaptability
Solution Approach 2:
The bracket includes nested telescoping elements and layered adjustment components that provide both stability in the final position and adaptability during the adjustment process, allowing the structure to lock firmly once configured
3Manufacturing precision
If custom brackets are designed for each seat track variation, then precise fit is achieved, but manufacturing complexity and cost increase
Solution Approach 1:
The bracket is designed as a universal component with built-in adjustment capabilities that allow a single bracket design to accommodate multiple seat track variations, eliminating the need for multiple custom bracket designs while maintaining precise fit for each application
