Heated Camera Bracket Assembly for Defrosting and Glare Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle camera bracket assemblies fail to properly capture objects or scenes under adverse weather conditions due to inadequate defrosting and glare issues.
Innovation Solution
The camera bracket assembly incorporates a heating element attached to a cell foam or a material layer with openings to direct heat towards the glass, and an adhesive and fiber material layer to mitigate glare, allowing for efficient defrosting and improved visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a heating element is added to defrost the glass, then the defrosting capability is improved, but the device complexity increases
Solution Approach 1:
The heating element is integrated into the bracket assembly structure itself, merging the defrosting function with the mounting bracket. This combination eliminates the need for separate defrosting devices and reduces overall system complexity while maintaining effective glass heating capability.
Solution Approach 2:
The bracket assembly serves multiple functions: mounting the camera and providing defrosting capability through the integrated heating element. This multi-functionality reduces the need for additional components and simplifies the overall system architecture.
2Object-affected harmful factors
If a fiber material layer is added to mitigate glare, then the glare reduction is improved, but the device complexity increases
Solution Approach 1:
The fiber material layer is integrated into the bracket assembly, combining the glare mitigation function with the structural component. This integration eliminates the need for separate glare reduction devices and simplifies the system while effectively reducing glare on the glass surface.
3Temperature
If cell foam is used to direct heat toward glass, then the heat directionality is improved, but the manufacturing precision requirements increase
Solution Approach 1:
Cell foam with its porous structure is used to direct heat toward the glass. The cellular structure naturally channels heat flow in specific directions, achieving effective heat directionality through the material's inherent properties rather than requiring precisely engineered geometric features, thus reducing manufacturing precision requirements.
