Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If fixed azimuth definitions are used for remote control, then the remote control system has a simple configuration, but the usability deteriorates when the remote controller is moved to different positions
Solution Approach 1:
The patent applies dynamics by making the azimuth definition dynamic rather than fixed. The system calculates the azimuth from the current position of the terminal device to the target electric equipment in real-time, allowing the remote control to adapt when the user moves to different locations. This resolves the contradiction by maintaining simple configuration while improving usability through dynamic position-based azimuth calculation.
Solution Approach 2:
The patent changes the parameter of azimuth from a fixed predefined value to a dynamically calculated value based on current position information. By using position information acquiring units and calculating azimuth based on current coordinates, the system allows the azimuth parameter to change with the user's position, thereby improving usability without significantly increasing system complexity.
2Ease of operation
If the remote controller uses position-based device selection, then the usability improves for obstacle-independent operation, but the device complexity increases due to multiple detection and calculation units
Solution Approach 1:
The patent applies universality by making the terminal device perform multiple functions: it serves as both the user interface and the detection/calculation system. The terminal device's existing position information acquiring units, azimuth detecting units, and inclination detecting units are utilized for remote control purposes, eliminating the need for separate dedicated detection devices and reducing overall system complexity while enabling obstacle-independent operation.
Solution Approach 2:
The system applies self-service by having the terminal device automatically calculate azimuth and select electric equipment based on its own position information and detection data. The control unit automatically performs the selection process without requiring manual intervention, thereby improving ease of operation while utilizing the terminal device's existing capabilities rather than adding significant complexity.
3Measurement precision
If the azimuth is calculated based on current position information, then the accuracy of device selection improves, but the loss of time increases due to real-time calculation requirements
Solution Approach 1:
The patent applies preliminary action by pre-acquiring and storing position information of electric equipment and using existing position information acquiring units in the terminal device. The system utilizes already-available position data and detection capabilities, performing calculations based on current positions without requiring time-consuming measurement processes, thereby maintaining high accuracy while minimizing time loss.
