Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the output state of the adaptor is detected with an oscilloscope using traditional methods, then the detection can be performed, but the detecting process becomes complicated with a large quantity of detecting instructions, resulting in low detecting efficiency and poor detecting accuracy

Engineering Contradiction:

Solution Approach 1:

The patent introduces an intermediary testing system comprising a testing board and host computer that mediates between the adaptor and the detection process. The testing board interfaces with the adaptor through communication lines and executes simplified detection instructions, while the host computer coordinates the overall testing process. This intermediary system transforms the complex oscilloscope-based direct detection into a structured multi-component testing architecture that reduces process complexity while maintaining or improving detection accuracy.

Inventive Principle:

Solution Approach 2:

The detection process is segmented into distinct functional components: the host computer manages test coordination and instruction generation, the testing board executes specific detection routines and interfaces with the adaptor, and the adaptor provides the output signals. This segmentation divides the originally monolithic complex detection process into manageable modular components, each responsible for specific tasks, thereby reducing overall process complexity while enabling more precise measurement through specialized functionality at each level.

Solution Approach 1:

The testing system performs preliminary actions by pre-configuring detection parameters, pre-compiling optimized detection instruction sets, and pre-establishing communication protocols between components. The host computer prepares comprehensive test scenarios in advance, and the testing board is pre-programmed with efficient detection routines. This preliminary preparation enables the system to execute comprehensive detections with fewer actual execution steps, thereby maintaining detection comprehensiveness while significantly improving detection efficiency.

Inventive Principle:

Solution Approach 2:

The testing system implements feedback mechanisms where the testing board continuously monitors adaptor output states and feeds back results to the host computer, which then adjusts subsequent detection instructions based on previous results. This feedback loop enables the system to achieve comprehensive detection coverage dynamically, adapting the detection process to actual adaptor behavior, thereby reducing the total number of instructions needed compared to static exhaustive detection methods while maintaining reliability.
