Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless communication is used to transmit control signals, then the ease of operation and remote control capability are improved, but the reliability of signal transmission deteriorates due to potential transmission errors
Solution Approach 1:
The patent implements feedback by having the control target device measure communication quality and report it back to the electronic apparatus. The electronic apparatus then uses this feedback to determine whether to adjust the operation plan, creating a closed-loop control system that continuously monitors and responds to communication conditions.
Solution Approach 2:
The patent applies dynamics by making the operation plan adjustable based on real-time communication quality. Instead of using a fixed operation plan, the system dynamically modifies the plan (such as adjusting speed or position) in response to changing communication conditions, allowing the control strategy to adapt to varying transmission reliability.
2Reliability
If the operation plan is adjusted based on communication quality, then the reliability of device operation is improved, but the device complexity increases due to additional measurement and decision-making components
Solution Approach 1:
The patent implements self-service by enabling the control target device to autonomously measure its own communication quality and provide this information to the electronic apparatus. The device performs self-diagnosis of its communication state without requiring external monitoring equipment, reducing overall system complexity while maintaining reliability.
Solution Approach 2:
The electronic apparatus performs multiple functions: it generates control signals, receives communication quality information, determines operation plan adjustments, and transmits adjusted signals. This multi-functionality consolidates control and monitoring capabilities into a single device, avoiding the need for separate specialized components and reducing system complexity.
3Measurement precision
If communication quality measurement is implemented, then the accuracy of control signal transmission is improved, but the loss of time increases due to additional measurement and processing steps
Solution Approach 1:
The patent applies preliminary action by having the control target device continuously measure communication quality in advance and report it to the electronic apparatus before the apparatus needs to make control decisions. This allows the electronic apparatus to receive ready-made quality assessments without performing measurements itself, saving time while maintaining measurement accuracy.
Solution Approach 2:
The patent extracts the communication quality measurement function from the electronic apparatus and places it in the control target device. This separation allows the measurement to occur independently and continuously at the device level, while the electronic apparatus only needs to receive and process the measured data, reducing the time burden on the central control system.
