Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If existing water intake mechanisms are used, then water intake function is achieved, but device complexity increases and maintenance requirements arise
Solution Approach 1:
The patent employs a spiral valve core geometry that rotates within a cylindrical valve body to control water flow. The curved spiral structure replaces complex multi-component mechanisms with a single rotating element that opens and closes the water intake channel through rotational motion, simplifying the overall device structure while maintaining reliable operation.
Solution Approach 2:
The invention uses a dynamic rotating valve core mechanism that transitions from static multi-valve arrangements to a single dynamic component. The valve core rotates to dynamically open and close water channels, enabling simple structural design with reliable maintenance-free operation through continuous rotational motion controlled by the fire-fighting robot's movement.
2Quantity of substance
If traditional water storage tanks are used, then water supply is provided, but water capacity is limited
Solution Approach 1:
The fire-fighting robot equips itself with water intake capability by rotating its valve core to connect with water sources along its track. The system serves itself by autonomously intaking water from external sources during operation, eliminating the need for large onboard storage tanks and extending operational duration without requiring additional volume for water storage.
Solution Approach 2:
The robot performs preliminary water intake actions by positioning itself at water sources and opening valves before firefighting operations begin. This allows the system to accumulate water in external sources or transfer it to smaller onboard containers, effectively increasing available water capacity without expanding the fire truck's volume.
3Ease of manufacture
If complex water valve mechanisms are used, then water flow control is achieved, but manufacturing complexity increases
Solution Approach 1:
The valve system is segmented into distinct functional modules: a rotating valve core with spiral channels, a valve body with fixed channels, and a control mechanism. This segmentation allows each component to be manufactured independently using standard machining processes, simplifying manufacturing while the assembled structure achieves complex flow control functions through the interaction of these simple modular elements.
