Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the tester manually inputs numerical data for transmission power variation through the operation unit, then the transmission test can be performed, but errors in setting the transmission power variation are likely to occur
Solution Approach 1:
The patent applies feedback by displaying a graph that visually represents the transmission power variation based on the numerical values input by the tester. This graph provides immediate visual feedback, allowing the tester to verify whether the input values correctly represent the intended transmission power variation pattern, thereby preventing setting errors
Solution Approach 2:
The patent uses visual representation through graphs where different visual elements (such as line positions, heights, or colors) correspond to different transmission power levels. This visual encoding helps the tester intuitively understand and verify the transmission power variation settings
2Reliability
If the tester inputs correct numerical data again after errors occur, then the test can be re-performed, but additional time is consumed
Solution Approach 1:
The graph display provides immediate visual confirmation of the transmission power variation settings, allowing the tester to detect errors before executing the test. This prevents the need for re-testing and reduces time loss
3Loss of information
If the tester wants to understand the transmission power variation settings, then detailed numerical data must be examined, but intuitive understanding becomes difficult
Solution Approach 1:
The patent transforms the one-dimensional numerical data into a two-dimensional graphical representation where the x-axis represents time and the y-axis represents transmission power level. This dimensional transformation makes the transmission power variation pattern immediately visible and intuitive while preserving all the numerical information
