Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If standard flow testing is performed on terminal products, then testing speed is maintained, but hardware issues such as insufficient soldering are not detected
Solution Approach 1:
The patent applies preliminary action by performing ageing detection before standard flow testing. A temperature-raising module pre-heats the terminal product to simulate long-term usage thermal effects, causing potential hardware defects like insufficient soldering to manifest earlier. This preliminary thermal stress treatment enables detection of latent defects that would otherwise remain hidden during normal-speed flow testing, thereby improving detection accuracy without permanently reducing productivity.
2Reliability
If high-temperature ageing testing is conducted to detect hardware issues, then detection accuracy improves, but testing time increases
Solution Approach 1:
The patent uses preliminary thermal stress application through the temperature-raising module to accelerate the manifestation of hardware defects. By pre-heating the terminal product before formal testing, potential issues like insufficient soldering are exposed earlier in the testing process. This allows the system to identify defective units quickly without requiring extended ageing periods, thus improving defect detection capability while minimizing time loss.
Solution Approach 2:
The patent applies parameter changes by dynamically adjusting the temperature parameter during testing. The temperature-raising module increases the operating temperature of the terminal product to simulate high-temperature environments that accelerate defect manifestation. This parameter change enables faster detection of hardware issues without requiring prolonged testing at normal temperatures, effectively reducing the overall testing duration while maintaining high detection accuracy.
3Reliability
If multiple service tests (data, voice, WLAN) are performed in high-temperature environment, then comprehensive detection is achieved, but system complexity increases
Solution Approach 1:
The patent applies universality by designing a multi-functional testing system where a single integrated platform can perform data service testing, voice service testing, and WLAN service testing. The system uses a unified temperature-raising module and control architecture that supports multiple test types, eliminating the need for separate dedicated testing equipment for each service type. This multi-functional approach achieves comprehensive service detection while keeping the overall system structure manageable through shared resources and modular design.
