Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a cleaning robot is used to clean the ground, then cleaning efficiency is improved, but diffusible waste may adhere to the robot and spread to surrounding areas, expanding the contaminated area
Solution Approach 1:
The patent applies preliminary action by equipping the cleaning robot with a contact detection device that detects waste before the cleaning operation proceeds. The detection device includes electrodes that sense changes in electrical parameters when contacting diffusible waste, triggering a control circuit to stop the robot or alert the user, thereby preventing waste spread before it occurs
Solution Approach 2:
The patent implements feedback by using the contact detection device to continuously monitor the cleaning environment and provide real-time information to the control circuit. When waste is detected through changes in electrical conductivity, capacitance, or resistance, the system feedbacks this information to automatically adjust the cleaning operation, either by stopping movement or notifying the user to prevent further contamination spread
2Measurement precision
If contact detection device with electrodes is added to detect diffusible waste, then waste detection capability is improved, but device complexity increases
Solution Approach 1:
The patent applies universality by designing a contact detection device that uses electrical parameters (conductivity, capacitance, resistance) to detect multiple types of diffusible waste including pet feces, liquids, and sauces. The same detection circuitry handles various waste types, and the control system统一管理 the detection signals, thereby reducing overall system complexity while maintaining broad detection capability
Solution Approach 2:
The patent uses an intermediary approach by introducing a control circuit that mediates between the contact detection device and the cleaning robot's driving assembly. The control circuit processes detection signals and generates appropriate control commands, simplifying the interaction between the detection system and the robot's movement system while enabling intelligent waste-responsive behavior
