Electrochromic Rearview Mirror Edge Structure for Stronger Adhesion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrochromic rearview mirrors face issues with the connection strength and aesthetics due to a small, flat outer periphery of the second substrate, leading to easy removal and noticeable chromatic aberration between the decoration fringe and the color-changeable portion.
Innovation Solution
The electrochromic rearview mirror enhances connection capability by incorporating a rough connection face on the second substrate with vertically extending plating layers and conductive glue, along with additional electricity transmission sheets to secure the connection and improve durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a plastic shell or decoration fringe is used to cover the glass periphery, then the aesthetics appearance is improved, but the connection strength is insufficient leading to easy removal
Solution Approach 1:
The invention transitions from a flat, two-dimensional connection surface to a three-dimensional rough connection face with vertical extensions. The fourth plating layer forms vertical turning extensions that extend downward from the flat surface, creating a stepped structure that increases connection area and strength while maintaining aesthetic appearance.
Solution Approach 2:
The invention applies different surface qualities to different regions: the front surface remains smooth and reflective for optimal image reflection, while the periphery features a rough connection face with vertical extensions specifically designed for enhanced adhesion. This localized differentiation solves both aesthetic and connection strength requirements.
2Shape
If a decoration fringe is electroplated on the glass periphery, then the aesthetics appearance is improved, but chromatic aberration occurs between the decoration fringe and color changeable portion
Solution Approach 1:
The fourth plating layer serves multiple functions simultaneously: it provides the decorative fringe function, acts as an electrical connection layer, forms the rough connection face for enhanced adhesion, and maintains color consistency with the electrochromic portion. This multi-functionality eliminates the need for separate decoration fringes that would cause chromatic aberration.
Solution Approach 2:
The invention merges the decorative fringe function, electrical connection function, and mechanical adhesion function into a single integrated fourth plating layer structure. This eliminates the separate decoration fringe that would cause chromatic aberration while achieving all required functions through one unified component.
