Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If two groups of ratchets are used in the button switching structure, then the switching function can be achieved, but the structural error increases and working stability deteriorates
Solution Approach 1:
The patent extracts one group of ratchets from the traditional two-group configuration, retaining only a single group of ratchets on the button. This reduction eliminates the complexity and structural errors associated with multiple ratchet groups while maintaining the essential switching function through the simplified button-ratchet engagement mechanism.
Solution Approach 2:
The patent segments the switching mechanism into distinct functional components: the button with its single ratchet group, the water cavity housing, and the outlet switching mechanism. This segmentation allows each component to perform its specific function independently, reducing overall system complexity and improving reliability.
2Ease of operation
If two groups of ratchets are coupled in the water cavity, then the switching mechanism functions, but maintenance and disassembly become inconvenient
Solution Approach 1:
The patent extracts the ratchet mechanism from the internal water cavity environment and positions it on the button, which is accessible from outside the water cavity. This extraction makes the ratchets visible and accessible for maintenance, disassembly, and assembly operations without requiring disassembly of the water cavity housing.
Solution Approach 2:
The button serves as an intermediary component that bridges the user's external control action with the internal water outlet switching mechanism. By placing the ratchets on this intermediary button rather than directly in the water cavity, the design enables easy external access for maintenance while still achieving the internal switching function.
3Ease of operation
If multiple components cooperate in the switching structure, then the outlet switching function is achieved, but the device complexity increases
Solution Approach 1:
The patent merges the button's pressing function with the switching function into a single integrated component. The button itself, with its single ratchet group, directly accomplishes both the actuation and the switching actions, eliminating the need for separate components that would otherwise be required in more complex designs.
Solution Approach 2:
The button is designed as a multi-functional component that simultaneously serves as the user interface for actuation, the housing for the ratchet mechanism, and the direct driver for the water outlet switching. This universality reduces the total number of components needed while maintaining full switching functionality.
