Floor Panel Holding Structure with Anchoring Portion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holding structures for mounted parts on floor panels do not allow for easy attachment and adjustable adhesive thickness between the floor panel and the body.
Innovation Solution
A holding structure featuring a floor panel with an adhesion surface and an anchoring portion, where the mounted part is anchored to the anchoring portion, and a connecting component fixes the mounted part to the body, allowing for adjustable adhesive thickness by setting a desired clearance between the adhesion surface and the body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mounted part is held on a floor panel using a clamp and anchoring structure, then the mounted part can be securely held, but the thickness of the adhesive agent between the floor panel and the body cannot be easily controlled
Solution Approach 1:
A spacer member is introduced as an intermediary component between the floor panel and the body. This spacer member has a predetermined thickness that directly controls the adhesive thickness, allowing precise control of the adhesive layer while maintaining secure holding through the anchoring portion that protrudes into the mounted part.
Solution Approach 2:
The anchoring portion is formed in advance on the floor panel during molding, and the spacer member is positioned beforehand with a predetermined thickness. This preliminary preparation allows the adhesive thickness to be controlled before the actual assembly, ensuring manufacturing precision without compromising holding strength.
2Device complexity
If the mounted part is directly anchored to the floor panel, then the structure is simple, but the adhesive thickness between the floor panel and the body cannot be adjusted to a desired value
Solution Approach 1:
The spacer member serves as a simple intermediary component that enables adhesive thickness adjustment without significantly increasing structural complexity. The anchoring portion remains integrated with the floor panel, maintaining simplicity while the spacer member provides the necessary thickness control functionality.
3Adaptability or versatility
If the anchoring portion is formed separately from the floor panel, then it can be adjusted independently, but the number of components increases
Solution Approach 1:
The anchoring portion is merged with the floor panel as an integral structure formed during molding, reducing the number of components. The adaptability is maintained through the spacer member that can be independently positioned and that provides the necessary adjustment capability for adhesive thickness control.

AI summary
A holding structure for holding a mounted part on a floor panel includes: a floor panel that extends in a vehicle front-rear direction and in a vehicle width direction, the floor panel including an adhesion surface that is joined via an adhesive agent to a first portion of a body, and an anchoring portion that protrudes from a surface on an opposite side from the adhesion surface; a mounted part that is anchored to the anchoring portion; and a connecting component comprising a first portion that is fixed to the mounted part, and a second portion that is fixed to a second portion of the body.
