Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If mobile transceiver units operate continuously in localizing mode to maintain precise position determination, then measurement precision is improved, but use of energy deteriorates
Solution Approach 1:
The system implements periodic position determination instead of continuous operation. The control unit activates transceiver units only when position determination is required, switching them between active and inactive states. This periodic activation maintains measurement precision when needed while significantly reducing energy consumption during idle periods.
Solution Approach 2:
The system dynamically adjusts the operational state of transceiver units based on real-time requirements. The control unit monitors process courses and workpiece positions, activating only the necessary transceiver units for current position determination tasks, thereby optimizing the balance between precision and energy usage.
2Use of energy by moving object
If mobile transceiver units are deactivated to reduce energy consumption, then use of energy is improved, but reliability deteriorates due to potential loss of position data
Solution Approach 1:
The control unit continuously monitors the position of workpieces and process courses, receiving feedback from active transceiver units. Based on this feedback, the control unit intelligently activates or deactivates transceiver units, ensuring that position determination reliability is maintained by keeping necessary units active while saving energy by deactivating unnecessary ones.
Solution Approach 2:
The system activates transceiver units in advance before position determination is needed and deactivates them after use. This preliminary activation ensures that position data is available when required without maintaining continuous operation, thus balancing reliability with energy efficiency.
3Measurement precision
If multiple transceiver units are activated simultaneously to improve position determination accuracy, then measurement precision is improved, but use of energy deteriorates
Solution Approach 1:
The system activates transceiver units based on their specific spatial location and the current position determination requirements. Instead of uniformly activating all units, the control unit selectively activates only those transceiver units that are necessary for determining the position of workpieces in their specific areas, optimizing both precision and energy consumption.
