Touch Control Panel Dual Wiring Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The reliability of touch control wirings in touch control panels is compromised due to manufacturing defects such as short circuits or open circuits, leading to reduced manufacturing yield and functionality.
Innovation Solution
A dual wiring system is implemented, where a first wiring is connected to touch control electrodes and a second wiring is connected to the binding area, allowing the second wiring to take over signal transmission when the first wiring fails, enhancing reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single wiring system is used in touch control panels, then the device complexity is reduced, but the reliability of touch control wiring deteriorates due to manufacturing defects such as short circuits or open circuits
Solution Approach 1:
The patent implements a dual wiring system where a second wiring is pre-configured as a backup before the first wiring fails. This preliminary action ensures that when manufacturing defects occur in the first wiring, the second wiring is already in place to immediately take over signal transmission, thus improving reliability without requiring complex real-time switching mechanisms.
Solution Approach 2:
The patent prepares compensatory measures in advance by incorporating a second wiring that can compensate for failures in the first wiring. This beforehand cushioning approach ensures that manufacturing defects do not lead to complete failure, as the second wiring serves as a pre-prepared safety net to maintain touch control functionality.
2Reliability
If a dual wiring system is implemented, then the reliability of touch control wiring is improved, but the device complexity increases
Solution Approach 1:
The second wiring is pre-configured during manufacturing as a backup path, eliminating the need for complex real-time detection and switching mechanisms. This preliminary preparation allows the system to maintain high reliability while keeping the overall device complexity manageable, as the backup path is already established before operation begins.
Solution Approach 2:
By incorporating the second wiring as a pre-prepared backup, the patent cushions against potential failures without requiring complex active management systems. The dual wiring architecture provides redundancy while maintaining relatively simple control logic, as the system can operate with either wiring without needing sophisticated switching mechanisms.
3Productivity
If the first wiring is used exclusively, then the ease of manufacture is improved, but the manufacturing yield deteriorates due to short circuit or open circuit faults
Solution Approach 1:
The second wiring is integrated during the manufacturing process as a backup path, allowing for preliminary detection and correction of defects. This preliminary action enables manufacturers to identify and address issues in the first wiring while the second wiring is still accessible, thereby improving manufacturing yield without significantly complicating the manufacturing process.
Solution Approach 2:
The dual wiring system provides a backup path that cushions against manufacturing defects, allowing panels with defective first wirings to still be produced successfully. This beforehand cushioning approach improves manufacturing yield by enabling recovery from defects that would otherwise result in complete panel rejection, while maintaining relatively straightforward manufacturing procedures.
