Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single-function testing device is used for electrical connectors, then the device structure remains simple, but the testing accuracy and reliability deteriorate because it cannot simulate different temperature conditions
Solution Approach 1:
The patent combines multiple testing functions into a single integrated testing device. The device merges environmental testing capabilities (temperature control assembly with heating and cooling functions), mechanical performance testing (plug testing device with clamp assemblies), and electrical performance testing into one unified system, thereby improving testing accuracy while managing device complexity through functional integration
Solution Approach 2:
The testing device is designed with multi-functionality to perform various types of tests on electrical connectors. The device can simulate different temperature conditions, perform mechanical plug actions, and conduct electrical performance tests, making it a universal testing platform that addresses the limitation of single-function devices
2Reliability
If environmental testing at different temperatures is added to the testing device, then the reliability of connector performance testing improves, but the device complexity increases due to additional temperature control components
Solution Approach 1:
The temperature control assembly is integrated with the plug testing device and control system. The heating assembly, cooling assembly, and temperature sensors are merged into a coordinated system that works together with the plug testing mechanisms, allowing environmental and mechanical tests to be performed simultaneously or sequentially within a unified device architecture
Solution Approach 2:
The control system acts as an intermediary that coordinates between the temperature control components and the testing functions. The control system receives testing parameters, manages the temperature control assemblies, and orchestrates the plug testing device operations, thereby managing device complexity through centralized control while enabling reliable multi-functional testing
