Seat Hooking Structure With Replaceable Slide Fastener
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle seat designs require replacement of the entire base trim cover when a slide fastener breaks, leading to increased repair costs.
Innovation Solution
A seat hooking structure featuring an open-type slide fastener with a fastener part and slider part, along with an anchoring member that secures the fastener to the seat member in a groove, allowing only the fastening member to be replaced without affecting the base trim cover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the slide fastener is sewn to the base trim cover, then the fastening is secure and reliable, but when the fastener breaks the entire base trim cover must be replaced increasing repair costs
Solution Approach 1:
The fastening system is divided into separate components: the base trim cover with groove, the anchoring member that secures to the groove, and the slide fastener that attaches to the anchoring member. This segmentation allows the slide fastener to be replaced independently without replacing the base trim cover, resolving the contradiction between reliable fastening and ease of repair.
Solution Approach 2:
The slide fastener is extracted from direct attachment to the base trim cover and instead attached to the anchoring member. This extraction allows the fastener to be removed and replaced independently, enabling cost-effective repair while maintaining the secure anchoring system.
2Ease of repair
If the slide fastener is made detachable to enable replacement, then repair cost is reduced, but the fastening strength may be compromised
Solution Approach 1:
The anchoring member combines two functions: it anchors securely to the groove in the base trim cover and provides attachment points for the slide fastener. This merging ensures that the detachable fastener maintains strong fastening strength through the robust anchoring mechanism while remaining replaceable.
Solution Approach 2:
The anchoring member is pre-installed and securely anchored to the groove in the base trim cover before the slide fastener is attached. This preliminary action ensures that when the fastener is replaced, the anchoring structure is already in place to provide immediate strong fastening, maintaining strength while enabling easy replacement.
