Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a universal remote control is used to control different electronic device brands, then the adaptability is improved, but the programming complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-loading numerical codes for multiple electronic device brands onto the remote control during manufacturing. This allows the remote to automatically input the correct codes for different brands without requiring users to manually search and enter codes, thereby resolving the contradiction between adaptability and programming complexity.
2Adaptability or versatility
If manual code input is required for programming, then the device can be customized, but the ease of operation deteriorates
Solution Approach 1:
The patent applies self-service by enabling the remote control to automatically perform code input and device identification functions. The remote autonomously searches for and programs the correct codes for different electronic devices without requiring manual user input, thus maintaining customization capability while dramatically improving ease of operation.
3Adaptability or versatility
If a secondary keypad with additional codes is added, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The patent applies the nested doll principle by placing a secondary keypad with additional numerical codes inside the remote control housing, accessible through a removable cover. This nested structure allows the remote to carry extensive code libraries for multiple brands without increasing the external dimensions or overall complexity of the device.
