Solution Overview
Problem
Existing display apparatuses face reliability issues due to complex processes and vibration sensitivity when designing printed circuit wiring to connect light sources to circuitry, particularly in implementing local dimming functions.
Innovation Solution
A display apparatus design featuring a light source module with a glass board, a rear chassis, and an electrically conductive supporter that maintains a constant distance between the board and the rear chassis, allowing direct electrical connection of printed circuit wiring to the circuitry without the need for a detour, thus simplifying the process and enhancing reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If printed circuit wiring is designed to extend to the edge of the board for electrical connection, then local dimming function is implemented, but manufacturing process complexity increases and reliability against vibrations deteriorates
Solution Approach 1:
The patent introduces an electrically conductive supporter as an intermediary component between the light source module and the rear chassis. This supporter provides both mechanical support and electrical connection pathways, allowing printed circuit wiring to be routed through the supporter rather than extending to the board edge, thus simplifying the manufacturing process while maintaining local dimming functionality
Solution Approach 2:
The electrically conductive supporter serves multiple functions simultaneously: it provides mechanical support for the light source module, maintains constant distance between components, and establishes electrical connections. This multi-functionality eliminates the need for separate structural and electrical components, reducing overall device complexity
2Adaptability or versatility
If printed circuit wiring is designed to extend to the edge of the board for electrical connection, then local dimming function is implemented, but reliability against vibrations deteriorates
Solution Approach 1:
The electrically conductive supporter acts as a robust intermediary structure that provides vibration-resistant electrical connections. By routing wiring through this supported pathway rather than to the board edge, the system achieves both local dimming capability and improved vibration resistance
Solution Approach 2:
The supporter structure provides pre-established mechanical and electrical support that cushions against vibration effects before they can cause damage to the wiring connections, thereby maintaining reliability under vibrational stress
3Ease of manufacture
If detour of printed circuit wiring is designed up to the edge of the board, then electrical connection to circuitry is achieved, but additional manufacturing process is required
Solution Approach 1:
The patent merges the mechanical support function and electrical connection function into a single electrically conductive supporter component. This integration eliminates the need for separate wiring detours to the board edge, simplifying the manufacturing process while maintaining electrical connectivity
