Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a remote control device uses a single antenna to receive infrared signals, then the device structure is simple, but the control reliability deteriorates due to signal blocking by objects in the line of sight
Solution Approach 1:
The patent divides the single antenna into multiple antennas (at least two) arranged in a specific geometric pattern. This segmentation allows the system to receive signals from multiple directions simultaneously, overcoming the limitation of single-point reception and eliminating the blocking problem caused by objects in the line of sight.
2Ease of operation
If a remote control device controls a plurality of controllable devices without positioning information, then the control process is simple, but the ease of operation deteriorates due to complex user interactions required to select the target device
Solution Approach 1:
The patent performs preliminary positioning actions by having controllable devices send out positioning signals that the remote control device receives in advance. The control unit determines the position of the target device before control operations are performed, eliminating the need for complex user interactions during the control process.
Solution Approach 2:
The system implements feedback by continuously receiving positioning signals from controllable devices and updating the position information. This feedback mechanism allows the remote control device to automatically track and identify the intended target device based on real-time positional data, simplifying the user interaction process.
3Measurement precision
If the remote control device uses radio signals for positioning, then the positioning precision is improved, but the loss of time increases due to signal transmission and processing delays
Solution Approach 1:
The patent replaces mechanical or manual positioning methods with radio signal-based positioning. The control unit determines the position of the target controllable device by processing radio signals, achieving high positioning precision through electronic signal analysis rather than mechanical measurement methods.
