Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If various lead wires and testing equipment are used for different tests at various testing stations, then comprehensive testing of LCD modules can be performed, but the testing table becomes cluttered and the testing process becomes inefficient
Solution Approach 1:
The patent implements a universal testing table that can perform multiple testing functions simultaneously through integrated testing circuits. Different testing stations (brightness, color, response time, etc.) are incorporated into a single table with standardized test interfaces, allowing one table to replace multiple specialized tables and eliminate the need for numerous lead wires and external equipment.
Solution Approach 2:
The patent combines multiple testing circuits, power supplies, and control systems into an integrated testing table structure. The testing circuits are embedded within the table itself, merging previously separate testing functions into a unified system that reduces equipment clutter and simplifies the testing environment.
2Reliability
If multiple testing stations with different testing circuits are used, then comprehensive quality testing can be performed, but the testing process requires manual intervention and becomes time-consuming
Solution Approach 1:
The patent implements automated testing where the integrated testing circuits automatically perform measurements and evaluations without manual intervention. The system self-manages the testing process by automatically connecting to LCD modules, executing test sequences, and generating test results, thereby eliminating the need for operators to manually connect lead wires and operate multiple testing devices.
Solution Approach 2:
The patent enables continuous automated testing operations where multiple LCD modules can be tested sequentially or in parallel without interruption. The integrated system maintains continuous operation by automatically transitioning between test subjects and maintaining optimal testing conditions throughout the process, maximizing productivity while ensuring comprehensive quality testing.
3Adaptability or versatility
If various lead wires are used to connect testing equipment to LCD modules, then different testing parameters can be measured, but the testing setup becomes complex and space-consuming
Solution Approach 1:
The patent extracts the testing circuit functionality from external equipment and embeds it directly into the testing table structure. This eliminates the need for separate external testing devices and their associated lead wires, consolidating all testing capabilities within the table itself and significantly reducing the space required for testing equipment and connections.

AI summary
An exemplary multi-signal input testing apparatus (2) includes a testing table (20), a transfer table (21) slidably positioned on the testing table, and a pair of multi-signal input devices (25) arranged on the transfer table. Each multi-signal input device includes a pair of connect ends (251, 252). One of the connect ends includes a plurality of pinhole terminals for receiving various testing signals, and the other connect end includes a plurality of connectors for supplying the testing signals to a product to be tested. This means that several tests can be automatically performed by a same multi-signal input testing apparatus at any single testing station. This speeds the testing of the products, and helps promote the efficiency of the testing process. In addition, it can simplify the configuration of various testing equipment and save space. Furthermore, there is little or no need for manual work by operators.
