Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an external receiver is used for the writing pen, then the writing pen can detect and transmit pressure value information, but the receiver occupies external space and is easy to lose
Solution Approach 1:
The patent integrates the receiver function into the main device body by incorporating a radio frequency signal element (including radio frequency IC and antenna) directly into the main device. This merging eliminates the need for separate external receivers, thereby saving space and preventing loss while maintaining reliable wireless communication for pressure value transmission.
2Adaptability or versatility
If an external receiver is spliced to the main device, then pressure value information can be received, but the structure becomes complex and space-consuming
Solution Approach 1:
The main device is designed with multi-functionality by integrating both the radio frequency signal element for wireless communication and the infrared light element for touch detection within the same device body. This universal design allows the main device to handle both pressure value reception and touch detection without requiring separate specialized receivers, thereby reducing overall system complexity.
3Productivity
If the radio frequency signal element is integrated in the infrared touch frame, then transmission efficiency is enhanced, but the filter strip must allow both infrared and radio frequency signals to penetrate
Solution Approach 1:
The filter strip is designed with local quality characteristics by creating specific regions that are transparent to both infrared light and radio frequency signals. The filter strip includes an infrared light transmission region and a radio frequency signal transmission region, allowing each type of signal to pass through its designated area without interference, thus maintaining high transmission efficiency while managing the complexity of dual-signal penetration.
