Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display systems in motor vehicles face challenges in maintaining structural integrity and minimizing openings in the support structure for electrical connections, which can compromise resistance to user interactions and increase complexity in grounding the display screen to the printed circuit.
Innovation Solution
A display system design featuring an electrically conductive face on the display screen connected to an electrically conductive region of the support via a conductive element, which is then grounded through another conductive element connected to the printed circuit, eliminating the need for additional openings in the support for grounding cables and enhancing structural resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connection cables pass through openings made in the support to electrically connect the display screen to the printed circuit, then electrical connection is achieved, but the support's resistance to stress and user manipulations is compromised
Solution Approach 1:
The patent merges the electrical connection function with the support structure itself by making the support electrically conductive. The support both mechanically holds the display screen and provides the electrical grounding path, eliminating the need for separate cables and openings. This integration resolves the contradiction by achieving reliable electrical connection without compromising structural strength.
Solution Approach 2:
The support structure is designed to perform multiple functions: mechanical support, positioning, and electrical grounding. By incorporating electrical conductivity into the support material or structure, it becomes a multi-functional component that simultaneously provides structural integrity and electrical connection, thereby resolving the trade-off between connection reliability and structural strength.
2Reliability
If multiple openings are made in the support for grounding cables, then complete electrical grounding is achieved, but the structural integrity and resistance to user interactions is reduced
Solution Approach 1:
The grounding function is merged into the support structure itself through electrical conductivity. Instead of requiring separate grounding cables to pass through multiple openings, the support's conductive material provides the grounding path directly, maintaining structural integrity while achieving reliable grounding.
3Reliability
If complex means are used to directly link the display screen to the printed circuit for grounding, then reliable electrical connection is achieved, but device complexity increases
Solution Approach 1:
The support structure serves as both the mechanical mounting element and the electrical grounding path. This merging eliminates the need for separate grounding cables, connectors, and routing mechanisms, thereby simplifying the overall device while maintaining reliable electrical connection between the display screen and printed circuit.
