Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired connection with additional cables is used for debugging, then reliable data transmission is achieved, but operation convenience deteriorates and time consumption increases
Solution Approach 1:
The patent combines power transmission and data transmission functions into a single USB interface. The test control device integrates a voltage generator and data processor that share the same physical connector, allowing simultaneous power supply and debugging through one cable rather than requiring separate cables for each function.
Solution Approach 2:
The USB interface is designed to perform multiple functions: it can supply power to the device under test, transmit debug data, and establish communication protocols. The test control device can operate in different modes (power-only mode, debug mode, or combined mode) depending on the connection type, making the system universally applicable to various debugging scenarios.
2Stability of the object's composition
If wired connection is used for debugging, then stable connection is achieved, but preparation time and complexity increase
Solution Approach 1:
The test control device automatically detects the connection type (wired or wireless) and configures itself accordingly. The processor identifies whether a USB device is connected and switches between debug modes automatically, eliminating the need for manual configuration and reducing setup time while maintaining connection stability when wired connection is available.
3Adaptability or versatility
If traditional debugging interface is used, then device compatibility is maintained, but interface compatibility problems occur
Solution Approach 1:
The patent uses the USB interface as a universal standard for both power and data transmission. By leveraging the widely adopted USB protocol and connector types, the test control device achieves broad compatibility with various devices while simplifying the interface requirements compared to traditional debugging setups that may require specialized connectors and protocols.
