Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a water-leaving detector with buoyancy device and sensing device is added to detect emergence from water surface, then measurement precision of waterline detection is improved, but device complexity increases
Solution Approach 1:
The buoyancy device is nested within the housing structure, and the sensing device is integrated with the buoyancy device. The buoyancy device moves between first and second positions within the housing, triggering the sensing device to transmit different signals. This nesting approach achieves accurate waterline detection while minimizing additional structural complexity.
2Use of energy by moving object
If the housing design includes separate chambers for water flow optimization, then energy consumption is reduced, but device complexity increases
Solution Approach 1:
The housing is divided into separate chambers that are interconnected, allowing optimized water flow paths. This segmentation enables the robot to reduce energy consumption by controlling water flow through specific chambers based on operational needs, while the modular chamber design integrates smoothly into the overall housing structure.
3Reliability
If a water flow velocity detection system is added to monitor filter clogging, then reliability of cleaning operation is improved, but device complexity increases
Solution Approach 1:
The water flow velocity detection system provides real-time feedback on water flow conditions through the filter. By monitoring flow velocity changes, the system can detect filter clogging and adjust cleaning operations accordingly, ensuring reliable cleaning performance. The feedback mechanism is integrated into the existing control system, minimizing additional complexity.
