Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless communication is performed by various electronic devices around the image display apparatus, then the surrounding communication environment becomes more complex, but the success rate of wireless pairing between the remote control device and the image display apparatus is lowered
Solution Approach 1:
The patent applies dynamics by making the transmission interval adaptive rather than fixed. The RF module dynamically adjusts its transmission interval based on whether pairing is completed, switching from a first interval during initial pairing attempts to a second interval (shorter than the first) when pairing fails, thereby adapting to varying communication conditions to improve pairing success rate
Solution Approach 2:
The patent changes the transmission interval parameter based on pairing status. When pairing is not completed, the system transitions from using the first interval to using the second interval (a shorter interval), effectively changing the communication parameter to improve reliability in complex wireless environments
2Reliability
If the RF module transmits wireless channel information at a shorter interval when pairing is not completed, then the pairing success rate increases, but the energy consumption increases
Solution Approach 1:
The patent uses periodic action with variable periods. The RF module transmits wireless channel information periodically, but the period (interval) changes based on pairing status: using the first interval during normal pairing attempts and switching to the shorter second interval only when pairing fails. This periodic transmission with adaptive period balancing improves pairing success while managing energy consumption
Solution Approach 2:
The system implements feedback by monitoring pairing completion status and adjusting transmission interval accordingly. When pairing is not completed, the system receives feedback and responds by switching to the shorter second interval for subsequent transmissions, creating a feedback loop that optimizes both pairing success rate and energy efficiency
