Integrated Attachment Member Structure for Compact Vehicle Interiors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing member attachment structures in vehicle interiors require a large space for separate resin clips, leading to a significant attachment portion size in depth, width, and height directions, which is inefficient.
Innovation Solution
A member attachment structure where the attachment member is integrated with a narrow hole, sandwiched portion, and wide hole on an attachment receiving plate, allowing for movement in the depth direction, with a protrusion and recess configuration that locks the attachment member in place without the need for a separate clip, reducing the attachment portion's size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate resin clip is used to attach the attachment member to the attachment receiving member, then the attachment member can be positioned in depth, width and height directions, but the attachment portion requires a large space for clip accommodation and elastic deformation
Solution Approach 1:
The invention merges the attachment receiving plate portion with the attachment member by integrating the insertion portion directly into the attachment member. This eliminates the need for a separate resin clip, thereby reducing the attachment portion size while maintaining positioning capability in depth, width and height directions through the integrated insertion portion and locking mechanism
Solution Approach 2:
The invention extracts the separate resin clip from the attachment system and replaces it with an integrated insertion portion that has the same positioning function. The insertion portion is directly formed on the attachment member, removing the need for external clip components and their associated accommodation spaces
2Reliability
If a separate resin clip is used for attachment, then the attachment member can be securely locked, but the attachment portion becomes large in depth, width and height directions
Solution Approach 1:
The locking mechanism is merged into the attachment member through the insertion portion that integrates positioning and locking functions. The insertion portion includes a locking hole that directly engages with the attachment receiving plate portion, eliminating the need for separate clip components and reducing attachment portion dimensions in all directions
Solution Approach 2:
The insertion portion serves multiple functions: it positions the attachment member in the depth direction, provides lateral support in the width direction through the narrow hole, and enables locking through the locking hole. This multi-functional integration replaces the separate clip's multiple functions within a more compact structure

AI summary
A member attachment structure, in which an attachment member is attached to an attachment receiving plate portion formed on an attachment receiving member, is provided. The attachment member includes an attachment body portion, and an insertion portion configured to be inserted into a wide hole of the attachment receiving plate portion. The insertion portion includes an insertion body portion, and a sandwiching portion configured to sandwich a sandwiched portion of the attachment receiving plate portion together with the attachment body portion from both sides in the height direction. A recess n is formed in one of the attachment member and the attachment receiving plate portion, and a protrusion is formed in the other. One of the attachment member and the attachment receiving plate portion is provided with a locking portion locked to a locked portion provided on the other of the attachment member and the attachment receiving plate portion.
