Vehicle Mirror Visor Trim Positioning Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle mirror devices lack effective stabilization of the relative positions between the bottom faces of the visor trim (housing body) and the visor cover (covering body), leading to potential deformation and instability.
Innovation Solution
The vehicle mirror device incorporates a support body, a housing body, a covering body, an up-down restricting section, a horizontal displacement restricting section, and an engagement section to stabilize the relative positions between the bottom faces, using abutting portions and engagement catches to restrict movement in various directions.

Engineering Contradiction Analysis
1Strength
If anchor tabs are inserted and anchored to communication sections, then deformation in the anchoring direction is prevented, but relative position stability between bottom faces of housing body and covering body is insufficient
Solution Approach 1:
The connection structure is segmented into multiple functional sections: up-down restricting sections with abutting portions for vertical position control, horizontal displacement restricting sections with abutting portions for horizontal position control, and engagement sections with engagement catches for securing. This segmentation allows each section to independently control specific movement directions, achieving comprehensive position stability between the housing body and covering body bottom faces.
Solution Approach 2:
The bottom wall sections of the housing body and covering body serve as intermediary elements that interface with the support body through multiple restricting sections. These intermediary structures transmit and distribute forces evenly, preventing concentrated stress while maintaining stable relative positions. The abutting portions and engagement catches act as mediators that coordinate the positioning between the two bodies.
2Stability of the object's composition
If multiple restricting sections are added to stabilize relative positions, then position stability is improved, but device complexity increases
Solution Approach 1:
Multiple restricting functions are merged into an integrated connection structure where the bottom wall sections, abutting portions, and engagement catches work together as a unified system. The up-down restricting sections, horizontal displacement restricting sections, and engagement sections are combined to simultaneously control vertical and horizontal positions while preventing deformation, achieving comprehensive stability without requiring separate independent mechanisms for each function.
Solution Approach 2:
The connection structure between the housing body and covering body serves multiple functions simultaneously: the abutting portions restrict up-down movement and horizontal displacement, the engagement catches secure the connection, and the bottom wall sections provide structural support and positioning. This multi-functionality reduces the need for additional separate components, maintaining structural efficiency while achieving comprehensive position stability.

AI summary
A vehicle mirror device including: a support body supported on a vehicle body side; a housing body housing the mirror; a covering body that covers the housing body at a back face side of the mirror; an up-down restricting section that restricts relative movement of the first bottom wall section and the second bottom wall section in the up-down direction; a horizontal displacement restricting section that restricts relative movement of the first bottom wall section and the second bottom wall section in the extension direction of the boundary; and an engagement section that is provided at mutually adjacent sides of the first and second bottom wall sections, such that the first and second bottom walls engage with each other in a state bearing tension in a direction to separate the first bottom wall section and the second bottom wall section from each other in a bottom view.
