Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing mounting bases for in-vehicle components on vehicle glass face challenges in accurately positioning rear-view mirrors and other accessories, leading to potential misalignment and interference with the mirror's function.

Innovation Solution

A mounting base system comprising a mirror base and a component base, where the mirror base is fixed to the component base, with the mirror base having a higher modulus of longitudinal elasticity than the component base, allowing for improved alignment and load distribution, reducing the risk of delamination and damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the bracket and supporting member are each independently positioned on the windshield glass surface, then the mounting flexibility is improved, but the positioning accuracy between the accessory unit and mirror unit deteriorates

Engineering Contradiction:

Improvemounting flexibilityVSAvoidpositioning accuracy

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent combines the bracket and supporting member into a single integrated mounting base structure. The mounting base includes a base body that directly supports the rear-view mirror, eliminating the need for separate positioning of independent components. This integration ensures accurate relative positioning between the mirror and accessory units while maintaining mounting flexibility through the unified structure's design.

Inventive Principle:

Principle #5Merging (Combining)

2Stability of the object's composition

If the bracket is made rigid to ensure stable mounting, then the mounting stability is improved, but the risk of delamination and damage to the glass surface increases

Engineering Contradiction:

Improvemounting stabilityVSAvoiddelamination and glass damage

Core Design Contradiction:

Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The patent specifies that the mounting base be made of a flexible resin material rather than rigid material. This parameter change in material properties allows the base to conform to the curved glass surface, distributing mounting loads more evenly and reducing stress concentrations that could cause delamination or glass damage, while still providing sufficient structural stability for mirror support.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The mounting base uses resin material that combines flexibility with adequate structural strength. This material selection creates a composite solution that balances mounting stability requirements with the need to protect the glass surface from damage and delamination, as the flexible resin can adapt to surface variations without exerting excessive localized stress.

AI summary

A mounting base for mounting in-vehicle components on an interior side of a vehicle glass, comprising a mirror base for mounting a rear-view mirror, and a component base for mounting an in-vehicle component other than the rear-view mirror is provided. The mirror base and the component base are each at least partially exposed on a mounting surface side of the vehicle glass. The mirror base is fixed to the component base, and formed of a material having a modulus of longitudinal elasticity greater than a modulus of longitudinal elasticity of the component base.
