Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a traditional temperature control system is used for SSD testing, then temperature control capability is provided, but the process is cumbersome and time-consuming for temperature setting and data feedback
Solution Approach 1:
The patent combines the temperature control function and data collection function into a single integrated testing apparatus. The control circuit simultaneously manages temperature regulation through the thermostatic device and data transmission through communication interfaces, eliminating the need for separate operations and reducing overall testing time.
Solution Approach 2:
The patent implements a feedback mechanism where the control circuit receives temperature data from the thermostatic device and adjusts temperature settings in real-time. The control circuit also feedbacks test data from the device under test to the communication interface, enabling rapid iteration between temperature adjustment and data collection.
2Adaptability or versatility
If multiple communication interfaces with different data formats are used, then compatibility with various devices is improved, but data processing complexity increases
Solution Approach 1:
The control circuit serves as an intermediary between different communication interfaces with different data formats. It receives data from one interface format, processes and converts it to the required output format, and transmits it through another interface, thereby maintaining compatibility without increasing overall system complexity.
Solution Approach 2:
The control circuit is designed with multi-functionality to handle multiple communication interface formats. It can process various data formats from different interfaces and adaptively convert them to suitable formats for further processing or transmission, making the system universally compatible with different devices.
3Measurement precision
If precise temperature control is implemented, then test accuracy at different temperatures is improved, but the system complexity increases
Solution Approach 1:
The patent replaces complex mechanical temperature control mechanisms with an electronic control system. The control circuit uses electronic signals to regulate the thermostatic device, achieving precise temperature control through software algorithms rather than complex mechanical adjustments, thereby reducing physical system complexity.
Solution Approach 2:
The control circuit achieves precise temperature control by dynamically changing control parameters such as heating power, cooling rate, and temperature setpoints. It adjusts these parameters in real-time based on feedback from temperature sensors, enabling accurate temperature maintenance without requiring complex mechanical structures.
