Inside Rearview Mirror Bracket Structure Against Assembly Breakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bracket structures for mounting inside mirrors in vehicles are prone to breakage due to unintended external forces during assembly, leading to frequent damage of fastening members.
Innovation Solution
A bracket structure incorporating a press member with greater tensile strength than the housing, featuring specific accommodation and mounting areas, and a fastening mechanism that distributes forces to prevent breakage, including inclined protrusions and angled support structures to enhance durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional bracket structure is used for mounting the inside mirror, then the assembly process is simple, but the bracket is prone to breakage from unintended external forces during assembly
Solution Approach 1:
The bracket structure is divided into two separate components: a bracket and a press member. The press member is inserted into the bracket's accommodation area and fastened independently. This segmentation allows each component to be optimized for its specific function, with the press member absorbing assembly forces and the bracket providing structural support, thereby preventing breakage without significantly increasing overall complexity.
Solution Approach 2:
The press member acts as an intermediary component between the bracket and the base member. It absorbs the unintended external forces during assembly through its higher tensile strength and specific mounting area design, protecting the bracket from breakage. The press member mediates the force transmission, ensuring that assembly forces do not directly stress the bracket's fastening members.
2Reliability
If the tensile strength of the bracket is increased to prevent breakage, then durability improves, but manufacturing cost and material requirements increase
Solution Approach 1:
Instead of increasing the tensile strength of the entire bracket structure, the patent applies local quality by concentrating the high tensile strength requirement only in the press member, which is the specific component subjected to assembly forces. The bracket itself maintains its original material properties, reducing overall material consumption while ensuring durability where needed through the press member's enhanced tensile strength.
3Stability of the object's composition
If the bracket structure is designed with higher rigidity to prevent deformation, then structural stability improves, but the bracket becomes more susceptible to breakage from concentrated forces
Solution Approach 1:
The structure is segmented into the rigid bracket (providing structural stability) and the press member (absorbing assembly forces). The bracket maintains its rigidity for stable mounting, while the press member's design with curved mounting areas and higher tensile strength allows it to flex and absorb concentrated forces during assembly, preventing breakage while preserving overall structural stability.
