Hexagonal Stabilizing Framework for Vehicle Seat Cushion Support Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cushion support plates for motor vehicle seat depth adjusters are complex to produce, prone to material fatigue due to high operational forces, and difficult to handle, leading to a short service life.
Innovation Solution
A cushion support plate with a stabilizing framework of hexagons or partial hexagons for weight savings and strength, featuring offset hooking arms with an S-shape design and open structure for easy operation, allowing the operating handle to be accessed externally without reaching under the seat.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional hooking arms are used for seat depth adjustment, then the operating handle can be connected to the cushion support plate, but the structure creates large forces that lead to rapid material fatigue and reduced service life
Solution Approach 1:
The hooking arm is divided into multiple sections (first section, second section, third section) that can pivot relative to each other. This segmentation allows the force to be distributed across multiple joints rather than concentrated in a single structure, reducing material fatigue and extending service life while maintaining the necessary mechanical advantage for operation.
2Ease of operation
If complex hooking arm structures are used to accommodate operating handles, then the handle can be operated in a partially pivoting manner, but the production becomes complex and expensive
Solution Approach 1:
The operating handle is integrated directly with the hooking arm structure, combining two separate components into one. The handle forms part of the hooking arm assembly, eliminating the need for separate mounting mechanisms and simplifying production while maintaining full operational functionality.
Solution Approach 2:
The hooking arm structure serves multiple functions: it provides the mechanical connection point for the operating handle, acts as a structural support element, and enables the pivoting motion necessary for adjustment. This multi-functionality reduces the overall number of components needed and simplifies manufacturing.
3Ease of operation
If the operating handle is positioned under the seat, then it can be connected to the cushion support plate, but handling becomes difficult as users must reach under the vehicle interior
Solution Approach 1:
The operating handle is repositioned from a vertical orientation under the seat to a horizontal orientation on the side of the cushion support plate. This dimensional change moves the handle into a more accessible location that users can reach without bending under the vehicle interior, significantly improving ease of operation.
