Transparent Bezel with Rounded Edge for Rearview Mirror
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rearview assemblies for vehicles lack an aesthetically pleasing and functional bezel design that meets safety and visibility requirements, particularly in terms of edge radius and concealment of structural elements, which affects the overall appearance and usability of the rearview mirror system.
Innovation Solution
A rearview assembly design featuring a partially optically transparent bezel with an edge radius greater than 2.5 mm, flush with the front surface of the rearview device, and a concealing layer to hide structural elements, providing a seamless appearance and enhanced user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional opaque bezel is used to conceal structural elements, then the hiding of structural components is improved, but the aesthetic appeal and visibility are reduced
Solution Approach 1:
The bezel transitions from an opaque state to a transparent state through electrochromic or PDLC film technology, changing its optical properties to reveal or conceal structural elements as needed, thus resolving the contradiction between hiding structural components and maintaining aesthetic appeal
Solution Approach 2:
The bezel incorporates dynamic switching capability that allows it to change between opaque and transparent states, enabling adaptive concealment of structural elements while maintaining aesthetic flexibility to satisfy both requirements under different conditions
2Reliability
If the bezel edge radius is increased to meet safety standards, then safety compliance is improved, but the seamless appearance with the front substrate is compromised
Solution Approach 1:
The bezel incorporates a localized rounded edge region with radius greater than 2.5mm at the perimeter to meet safety standards, while the central region maintains a flush, seamless appearance with the front substrate, thus satisfying both safety requirements and aesthetic continuity
Solution Approach 2:
The bezel edge is designed with a controlled curvature radius exceeding 2.5mm to comply with safety regulations, creating a smooth transition that minimizes visual disruption while maintaining the required geometric form for safety compliance
3Shape
If a transparent bezel is used to enhance aesthetic appeal, then visibility and appearance are improved, but the concealment of structural elements is reduced
Solution Approach 1:
The bezel incorporates dynamic switching capability that allows it to change between opaque and transparent states, enabling adaptive concealment of structural elements while maintaining aesthetic flexibility to satisfy both requirements under different conditions
Solution Approach 2:
The bezel transitions from an opaque state to a transparent state through electrochromic or PDLC film technology, changing its optical properties to reveal or conceal structural elements as needed, thus resolving the contradiction between hiding structural components and maintaining aesthetic appeal

AI summary
A rearview assembly having a mounting structure configured to be operably coupled with a vehicle. A housing is operably connected with the mounting structure and a rearward viewing device is supported by one of the housing and the mounting structure. The rearward viewing device provides a rearward view to a vehicle driver and includes a front substrate and a rear substrate. The entire front surface of the front substrate is exposed and the entire rear substrate is positioned behind the front substrate. A concealing layer is disposed about a periphery of the rearward viewing device between the front substrate and the rear substrate. A partially optically transparent bezel is disposed adjacent to both the rearward viewing device and the housing, the optically transparent bezel having an edge radius greater than 2.5 mm and the optically transparent bezel being substantially flush with the front surface of the front substrate.
