Vehicle Window Display Assembly With Moisture-Protected Signal Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle window assemblies with display functions are prone to moisture ingress, which affects the display functionality by entering the display panel or signal elements, necessitating a protective solution.
Innovation Solution
A vehicle electronic device design featuring a vehicle window assembly with a display panel sandwiched between protective substrates, where a first signal element is electrically connected to the display panel and covered by a protective element, such as a waterproof material, to prevent moisture intrusion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle window assembly includes a display panel and signal elements, then the display function and signal transmission are improved, but moisture ingress occurs affecting reliability
Solution Approach 1:
The signal element is nested within a cavity formed by the first and second protective substrates. The first protective element is positioned within this cavity structure, creating a nested arrangement where the protective element is housed within the space defined by the protective substrates, providing moisture protection without adding external structural complexity
Solution Approach 2:
The protective structure is segmented into multiple functional components: first protective substrate, second protective substrate, and first protective element. Each segment serves a specific protective function, allowing the system to address moisture ingress at multiple levels while maintaining modular design that avoids excessive overall complexity
2Reliability
If protective substrates and protective elements are added to prevent moisture ingress, then reliability is improved, but the device structure becomes more complex
Solution Approach 1:
The first protective substrate serves multiple functions: it provides structural support for the display panel, creates a cavity for housing the signal element, and works in conjunction with the second protective substrate to form a moisture barrier. This multi-functionality reduces the need for additional dedicated protective components
Solution Approach 2:
The first protective element covers at least a portion of the signal element, providing sufficient moisture protection for the critical signal transmission areas without requiring complete encapsulation of all components. This partial protection approach achieves adequate reliability while minimizing the number and complexity of protective components
