Engineering Contradiction Analysis
1Adaptability or versatility
If infrared communication is used for remote control, then wireless control capability is achieved, but interference occurs when multiple devices with the same IR protocol are in the same space
Solution Approach 1:
The patent segments the communication process into two distinct phases using different communication methods: a first communication method for forming communication channels (pairing) and a second communication method for transmitting control signals. This segmentation allows the system to establish dedicated communication pathways between the remote control device and the target electronic device, preventing interference from other devices while maintaining wireless control capability.
Solution Approach 2:
The patent introduces an intermediary communication channel mechanism that establishes a dedicated pathway between the remote control device and the target electronic device. By forming a communication channel through the first communication method before transmitting control signals via the second communication method, the system creates a private communication corridor that isolates the control signal from potential interference by other devices in the same space.
2Device complexity
If a single communication method is used for all operations, then device complexity is reduced, but control precision and device identification accuracy deteriorate
Solution Approach 1:
The patent applies dynamics by making the communication method selectable based on the operational phase. The system dynamically switches between a first communication method for channel formation and a second communication method for control signal transmission. This dynamic adaptation allows the system to optimize for device identification accuracy during pairing while maintaining simplicity during actual control operations, resolving the contradiction between complexity reduction and precision maintenance.
Solution Approach 2:
The patent changes the communication parameter (method type) based on the operational context. By selecting different communication methods for different phases (channel formation vs. control signal transmission), the system optimizes both device identification accuracy and overall system simplicity. The parameter change allows high-precision identification during pairing without permanently increasing device complexity.
3Measurement precision
If communication channel is formed before control signal transmission, then device identification accuracy is improved, but communication time is increased
Solution Approach 1:
The patent applies preliminary action by establishing the communication channel through the first communication method before transmitting control signals. This preliminary channel formation ensures accurate device identification and prevents interference, though it does add some time delay. The benefit is that once the channel is established, subsequent control signal transmission is efficient and reliable.
Solution Approach 2:
The patent implements periodic action by using distinct communication methods for distinct phases: first for channel formation and second for control signal transmission. This periodic switching between communication methods allows the system to optimize for identification accuracy during the pairing phase without permanently increasing communication time, as the efficient second method is used for all subsequent control operations.
