Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses face challenges in efficiently connecting circuit patterns on substrates to metal structures, leading to complex circuit designs and increased manufacturing processes, while also risking electrostatic discharge and component protection.
Innovation Solution
A supporter is mounted on the substrate with a body that aligns with through-holes, featuring a circuit pattern portion electrically connected to the substrate's circuit pattern and a metal portion extending to contact the metal structure, simplifying the circuit design and reducing the need for via holes or jumpers, thereby enhancing stability and protecting components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional connection methods (via holes or jumpers) are used to connect circuit patterns to metal structures, then electrical connection is achieved, but circuit design becomes complex and manufacturing processes increase
Solution Approach 1:
The patent combines the supporter structure with the connection function by integrating a metal portion directly into the supporter body. This metal portion extends from the supporter and makes direct contact with the metal structure, eliminating the need for separate via holes or jumpers. The supporter thus serves dual purposes: mechanical support and electrical connection, reducing overall device complexity while maintaining reliable electrical connectivity.
Solution Approach 2:
The supporter is designed to perform multiple functions simultaneously: it provides mechanical support for the optical member, establishes electrical connection between the circuit pattern and metal structure, and offers electrostatic discharge protection. This multi-functionality reduces the number of separate components needed, simplifying both circuit design and manufacturing processes.
2Reliability
If traditional connection methods are used, then electrical connection is established, but manufacturing complexity and process steps increase
Solution Approach 1:
The manufacturing process benefits from the merged design where the metal portion is integrated into the supporter structure. This allows the supporter to be manufactured as a single component that simultaneously provides mechanical support and electrical connection, reducing the number of assembly steps and manufacturing operations required compared to traditional methods using separate via holes or jumpers.
3Reliability
If circuit patterns are connected to metal structures through multiple intermediate connections, then electrical connection is achieved, but connection length increases and stability decreases
Solution Approach 1:
The patent extracts and eliminates the unnecessary intermediate connection elements (via holes and jumpers) from the traditional connection path. By using a direct metal portion extending from the supporter to contact the metal structure, the connection path is shortened and simplified, improving both stability and reducing connection length.
4Object-affected harmful factors
If proper electrostatic protection is implemented, then components are protected, but additional structures or processes may be required
Solution Approach 1:
The metal portion of the supporter serves dual purposes: establishing electrical connection and providing electrostatic discharge protection. By making the metal structure accessible through the supporter's metal portion, the design enables ESD protection without requiring additional protective structures or processes, thus avoiding increased device complexity.
