Vehicle Mirror Spherical Seal Gap for Smooth Adjustment in Cold Conditions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle mirror devices with sliding mechanisms experience increased contact force between components under low-temperature conditions, leading to rough angle adjustments and potential water penetration due to gaps between sliding parts.
Innovation Solution
A vehicle mirror surface angle adjusting device featuring a stationary member with a spherical surface and a movable member, separated by a gap sealed with a sealant, allowing smooth rotation and preventing water ingress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a gap is provided between the sliding site and the contact surface to reduce contact force, then smooth sliding is achieved, but water penetration risk increases
Solution Approach 1:
A seal member is introduced as an intermediary component between the sliding site and the contact surface. This seal member fills the gap to prevent water penetration while allowing the sliding movement to occur smoothly, thus resolving the contradiction between smooth sliding and water penetration prevention
Solution Approach 2:
The seal member functions as a flexible barrier that can deform during sliding while maintaining the seal. This flexible component prevents water from penetrating through the gap without interfering with the sliding motion between the mirror holder and the case
2Object-affected harmful factors
If sliding parts are in direct contact to prevent water penetration, then sealing is improved, but contact force increases causing rough adjustment
Solution Approach 1:
The seal member serves as a mediator that separates the sliding site from direct contact with the contact surface. It provides water penetration prevention through sealing while allowing the sliding parts to move smoothly with reduced contact force
Solution Approach 2:
The seal member is positioned specifically at the gap between the sliding site and the contact surface, providing sealing only where needed. This localized sealing approach prevents water penetration without creating friction across the entire sliding interface, maintaining smooth adjustment

AI summary
The present invention includes a stationary member, a movable member, a holding member, and a driving member. The stationary member has a stationary-side spherical surface. The movable member has a movable-side spherical surface. The stationary-side spherical surface and the movable-side spherical surface together forms a gap. The stationary-side spherical surface and the movable-side spherical surface are interposed with a sealant, which seals the gap. Consequently, the present invention allows smooth adjustment of an angle of a mirror surface, and prevention of water penetrating inside.
