Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a universal remote controller is used to replace multiple original remote controllers, then the number of remote controllers is reduced and user convenience is improved, but a complicated test procedure is required to find the correct device code
Solution Approach 1:
The patent implements an automated feedback mechanism where the remote controller automatically tests device codes and receives feedback from the controlled device (TV) to determine whether the code is correct. The system displays real-time test results and automatically proceeds through the testing sequence without requiring manual intervention for each code attempt, thereby resolving the contradiction between universal adaptability and test procedure complexity.
Solution Approach 2:
The remote controller performs self-testing and self-configuration by automatically cycling through device codes in the database and determining correctness based on the controlled device's response. The system independently completes the code-finding process without requiring user guidance through each step, eliminating the need for complex manual testing procedures while maintaining universal remote control functionality.
2Reliability
If all device codes are tested manually to ensure the correct code is found, then the correct device code can be identified, but the procedure is time-consuming and strenuous for users
Solution Approach 1:
The patent pre-organizes device codes in a database according to appliance categories and implements a predetermined testing sequence. Before actual use, the system has all necessary codes prepared and arranged in an optimized testing order, allowing rapid automatic testing during setup without requiring users to manually try each code, thus ensuring reliable code identification while minimizing time loss.
Solution Approach 2:
The patent replaces the manual mechanical process of trying codes one by one with an automated electronic testing system. The microcontroller automatically cycles through codes, sends test signals, and interprets responses electronically, substituting the time-consuming manual trial-and-error process with rapid automated electronic verification that maintains accuracy while dramatically reducing time and effort.
3Reliability
If users manually test each function key with every device code, then the correct code can be confirmed, but users need high concentration and the process becomes quite strenuous
Solution Approach 1:
The remote controller performs self-verification by automatically testing each function key with the current device code and determining correctness based on the controlled device's response. The system independently verifies whether codes are correct without requiring user concentration or manual checking, thereby maintaining reliable code verification while dramatically simplifying the operation to merely selecting the appliance type and pressing a start button.
Solution Approach 2:
The system implements automated feedback where the controlled device's response to each test signal is automatically captured and interpreted by the microcontroller. The system displays clear feedback indicators showing which codes are correct and which are incorrect, eliminating the need for users to concentrate and manually determine correctness, thus maintaining verification reliability while improving ease of operation.
