Vehicle Floor Attachment Structure for Carpet and Insulator Fixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing vehicle floor structure requires multiple members to fix the insulator and floor carpet in two layers, which increases complexity and member count.
Innovation Solution
A single attachment member with a fixation part, harness protection part, and regulation part is used to fix the insulator to the vehicle body side, thereby fixing the floor carpet as well, reducing the number of required members and providing additional protection and positioning regulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple members (stay, side sill scuff, hook) are used to fix the insulator and floor carpet separately, then the fixation reliability is improved, but the device complexity and number of members increase
Solution Approach 1:
The patent combines multiple fixation functions into a single attachment member. The attachment member includes a stay with an insertion groove for fixing the insulator, and a side sill scuff with a hook for fixing the floor carpet. By integrating these previously separate components into one unified attachment member, the patent reduces the number of members while maintaining the fixation reliability provided by multiple attachment points.
Solution Approach 2:
The attachment member serves multiple functions simultaneously: it acts as both the stay for insulator fixation and the side sill scuff for carpet fixation. This multi-functional design eliminates the need for separate dedicated components for each fixation task, thereby reducing overall device complexity while ensuring reliable fixation for both layers.
2Reliability
If a dedicated harness protection member (corrugated tube) is provided, then the wire harness protection is improved, but the device complexity increases
Solution Approach 1:
The attachment member is designed to serve as both a fixation component and a wire harness protection component. The stay portion of the attachment member includes a protection part that shields the wire harness from damage during installation and use. This eliminates the need for a separate dedicated protection member like a corrugated tube, reducing device complexity while maintaining protection reliability.
3Reliability
If the floor carpet is fixed with a separate hook and side sill scuff, then the position regulation is improved, but the device complexity increases
Solution Approach 1:
The patent merges the position regulation function into the attachment member itself. The side sill scuff includes a hook that engages with the floor carpet, and the regulation part is integrated into this structure. This allows the floor carpet to be properly positioned and regulated without requiring a separate dedicated regulation component, thereby reducing the number of members while maintaining position regulation effectiveness.
