Rearview Mirror Bezel With Integrated Lighting and Protected Electronics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rearview mirror assemblies have inefficiencies in space utilization and manufacturing costs due to separate modules for different functions, leading to exposed components and lost installation space during adjustment, which limits the integration of additional features and information for drivers.
Innovation Solution
A multi-function rearview device with a bezel that integrates multiple light assemblies and electronic components, including a camera and display, attached to a movable housing that adjusts as a single unit, allowing for enhanced space utilization and additional feature integration behind the rearview element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate modules are used for different functions in rearview mirror assemblies, then each function can be independently implemented, but space utilization is reduced and manufacturing costs increase
Solution Approach 1:
The patent integrates multiple separate functional modules (turn signal indicator, blind spot indicator, approach light, puddle light, logo light, and cosmetic mirror light) into a single integrated circuit board. This merging eliminates the need for separate modules, reducing overall space requirements while maintaining all individual functions within the mirror assembly housing.
2Adaptability or versatility
If separate modules are used for different functions in rearview mirror assemblies, then each function can be independently implemented, but manufacturing costs increase
Solution Approach 1:
The patent consolidates multiple light sources, control circuits, and connection terminals onto a single integrated circuit board. This reduces the number of separate components that need to be sourced, assembled, and tested, thereby lowering manufacturing complexity and cost while maintaining full functional capability.
3Ease of operation
If the rearview element is moveable for adjustment, then driver positioning is improved, but components are exposed to environmental conditions during adjustment
Solution Approach 1:
The patent nests the integrated circuit board containing all electronic components and light sources within a protected housing that remains stationary. The moveable rearview element is mechanically coupled to this protected assembly, allowing the element to adjust while the sensitive electronic components remain enclosed and shielded from environmental conditions throughout the adjustment range.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides improved space utilization and reduced manufacturing costs by integrating multiple functions into a single, sealed unit, enabling additional features and improved driver information without exposing components to environmental conditions during adjustment.
Implementation Method 1
at least one light assembly positioned within the interior space of the bezel
