Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mirror assemblies for vehicles lack an efficient power distribution system that can simultaneously power lighting modules, heating assemblies, and electro-optic components, leading to potential overheating and reduced functionality.
Innovation Solution
A power hub is electrically coupled to conductive traces on a printed circuit board (PCB) to provide power to both the lighting module and the heating assembly, with an additional trace for the electro-optic assembly, allowing for independent control and efficient energy distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a shared power hub is used to power multiple components, then energy distribution efficiency is improved, but the risk of overheating increases
Solution Approach 1:
The power distribution system is segmented into multiple independent power hubs, each serving specific components. This segmentation allows for isolated thermal management and prevents heat accumulation from affecting the entire system, while maintaining efficient energy distribution to individual components.
Solution Approach 2:
Different power hubs are strategically positioned in areas with varying thermal characteristics. Power hubs for high-heat components are placed in well-ventilated areas, while those for low-heat components are positioned elsewhere. This local quality approach optimizes thermal management for each specific power distribution zone.
2Ease of operation
If multiple components are powered independently, then control precision is improved, but device complexity increases
Solution Approach 1:
The mirror assembly is divided into functional modules (lighting module, heating assembly, electro-optic assembly), each with its own dedicated power hub. This segmentation enables independent control of each component while keeping the overall system manageable through modular architecture.
Solution Approach 2:
Each power hub is designed as a universal module capable of powering any component type. This multi-functionality reduces the need for component-specific power distribution circuits, thereby controlling system complexity while maintaining precise control over each component.
3Area of stationary object
If a compact power distribution system is used, then space efficiency is improved, but heat dissipation becomes difficult
Solution Approach 1:
Power hubs are arranged in a three-dimensional configuration within the mirror assembly, utilizing vertical space and depth rather than only horizontal area. This dimensional arrangement maintains compact footprint while creating thermal pathways for effective heat dissipation.
Solution Approach 2:
The compact power distribution system uses segmented power hubs with integrated thermal management features. Each hub is designed as a compact unit with internal heat sinks and thermal pathways, allowing efficient heat dissipation within a small form factor.

AI summary
A mirror assembly for a vehicle includes a lighting module that is configured to illuminate through a section of the mirror assembly. An electro-optic assembly includes a front substrate having a first surface and a second surface opposite the first surface. A second substrate has a third surface and a fourth surface opposite the third surface. The second and third surfaces face each other to define a gap. A first electrode is coupled to the second surface, and a second electrode is coupled to the third surface. An electro-optic medium is located between the first electrode and the second electrode. A power hub is in electrical communication with and provides power to both the lighting module and the electro-optic assembly.
