Vehicle Emblem Attaching Structure to Prevent Grill Backlash
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing attachment structures for attaching an emblem to a vehicle grill may lead to backlash or looseness without a fastening structure at the attached member.
Innovation Solution
An attaching member comprising a first member with a first engaging portion and a second member with a second engaging portion, where the engaging portions are designed to engage with the attached member's frame portions from opposite sides, preventing movement and ensuring stable attachment without additional fastening structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fastening structure is provided at the attached member to stabilize attachment, then attachment stability is improved, but device complexity increases
Solution Approach 1:
The attaching member is divided into two separate members: a first member with a first engaging portion that engages the first frame portion, and a second member with a second engaging portion that engages the second frame portion. This segmentation allows each member to be optimized for its specific engagement function, achieving stable attachment without requiring complex fastening structures at the attached member.
Solution Approach 2:
The first engaging portion and second engaging portion are nested within the same attaching member assembly, with both engaging portions working together to secure the attaching member to the attached member. This nesting arrangement consolidates multiple engagement functions into a single integrated assembly, reducing overall device complexity while maintaining attachment stability.
2Device complexity
If no fastening structure is provided at the attached member, then device complexity is reduced, but attachment stability deteriorates causing backlash
Solution Approach 1:
The attaching member is designed to be self-sufficient by incorporating both the first engaging portion and second engaging portion within itself. This self-service design enables the attaching member to achieve stable attachment to the attached member without requiring any additional fastening structures or modifications to the attached member, thereby reducing device complexity while maintaining reliability.
3Reliability
If engaging portions engage from opposite sides of the second direction, then attachment stability is improved by restricting movement, but manufacturing precision requirements increase
Solution Approach 1:
The first engaging portion and second engaging portion are designed with asymmetric configurations relative to each other, with the first engaging portion engaging the first frame portion from one side and the second engaging portion engaging the second frame portion from the opposite side. This asymmetric arrangement effectively restricts movement in multiple directions, improving attachment stability while distributing precision requirements across different engagement points rather than requiring uniform high precision throughout.

AI summary
An attaching member comprises a first member including an engaging portion and a first engaging portion to engage with a first frame portions from one side of a second direction and a second member including an engaged portion and a second engaging portion to engage with a portion of the first frame portion which is positioned on the other side, in the second direction, of the first engaging portion from the other side of the second direction. The engaging portion includes an inclined portion positioned on the above-described one side of the second direction and extending obliquely from a tip of the engaging portion toward its base portion and from the above-described other side of the second direction to the above-described one side of the second direction. A portion of the engaging portion positioned on the above-described one side of the second direction engages with the engaged portion.
