Seat Backrest Support Assembly for Wrinkle-Free Trim Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bucket-type vehicle seats face issues with upholstery tensioning and fixation, leading to deformation, folds, and accelerated deterioration due to modifications in the seat structure for trim part assembly, which affects the visual appearance and durability.
Innovation Solution
A support assembly for decorative elements on vehicle seat backrests, comprising a main body with fixing elements, receiving elements, and tightening elements, allowing direct upholstery tightening and trim part retention without modifying the seat structure, using through-holes and clips for secure attachment to conventional headrest rods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If trim parts are assembled after upholstery is completed, then the seat structure can accommodate decorative elements, but the upholstery tension is modified introducing additional tensions that impair surface finish and accelerate deterioration
Solution Approach 1:
The support assembly with receiving elements is installed on the seat structure before upholstery is completed. This preliminary installation allows the upholstery to be tensioned and fixed around the support assembly, and only after this proper tensioning is achieved are the trim parts assembled into the receiving elements. This sequence prevents additional tensions that would impair upholstery surface finish and durability.
Solution Approach 2:
The support assembly acts as an intermediary component between the seat structure and the trim parts. It provides receiving elements that accommodate trim parts while allowing the upholstery to be properly tensioned and fixed around it. This intermediary structure enables both the upholstery to maintain proper tension and the trim parts to be securely assembled without directly conflicting with each other.
2Reliability
If specific connection means are used to fix trim support assembly to seat structure, then the trim assembly can be secured, but the seat structure must be modified in a specific manner that increases complexity
Solution Approach 1:
The support assembly is designed with fixing elements that can be universally adapted to conventional seat structures without requiring specific modifications. The support assembly itself serves multiple functions: it provides fixation to the seat structure through its fixing elements, creates openings in the upholstery, and offers receiving elements for trim parts. This multi-functionality eliminates the need for specific connection means and structure modifications, reducing overall complexity.
Solution Approach 2:
The trim support system is segmented into distinct functional components: fixing elements for attaching to the seat structure, the support assembly body that creates openings, and receiving elements for trim parts. This segmentation allows each component to be optimized independently and facilitates easy installation and removal without modifying the underlying seat structure, thereby reducing complexity while maintaining reliable fixation.
