Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a spring and water passing hole are added to achieve resettable engine switching, then the reset function is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent extracts and eliminates the spring component from the traditional resettable engine structure. Instead of using a spring to provide reset force, the invention uses a sealing gasket that can be directly actuated by water pressure to achieve the reset function, thereby simplifying the overall structure and reducing manufacturing complexity
Solution Approach 2:
The sealing gasket is designed to be directly actuated by water pressure from the water division chamber, eliminating the need for external spring mechanisms. The water pressure itself performs the work of moving the switching bracket and resetting the engine, making the system self-service and reducing component complexity
2Reliability
If a spring is added to achieve resettable engine switching, then the reset function is improved, but the product size increases
Solution Approach 1:
The spring component is completely removed from the structure. The reset function is achieved through the sealing gasket's direct interaction with water pressure, which eliminates the space requirements for spring mechanisms and allows for a more compact product design
Solution Approach 2:
The sealing gasket serves multiple functions: it seals the water outlet holes, acts as a switching element, and provides the reset function through water pressure actuation. By merging these functions into a single component, the overall product size is reduced compared to traditional designs that require separate spring mechanisms
3Reliability
If water passing holes are added to achieve resettable engine switching, then the reset function is improved, but the manufacturing difficulty and cost increase
Solution Approach 1:
The water passing holes are eliminated from the design. The reset function is achieved through the sealing gasket's ability to block water outlet holes and be actuated by water pressure in the water division chamber, simplifying the manufacturing process and reducing production difficulty
Solution Approach 2:
The water pressure system serves dual purposes: it provides the driving force for the engine and simultaneously actuates the sealing gasket for resetting. This self-service approach eliminates the need for additional water passing holes and complex routing, making the manufacturing process easier and more cost-effective
