Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two barrels are used to adjust high and low volume flushing water, then double flow control is achieved, but the drainage volume becomes unstable and the structure becomes complicated
Solution Approach 1:
The patent divides the single float chamber into two separate float chambers (first float chamber and second float chamber), each with its own float component. This segmentation allows independent control of high and low drainage volumes while simplifying the overall control mechanism. Each float chamber can be adjusted independently through its own adjusting component, eliminating the need for complex two-barrel mechanisms.
Solution Approach 2:
The patent introduces adjustable components that allow dynamic modification of the float chamber volume and flowing passage cross-section. The adjusting component can change the volume of the first float chamber, and the control component can adjust the cross-section of the flowing passage, enabling flexible adaptation of drainage volume without requiring fixed complex structures.
2Adaptability or versatility
If two sealing pads are closed for high and low drainage volume, then flow control is achieved, but leakage occurs and operation becomes complicated
Solution Approach 1:
The patent employs a soft touch valve body that automatically closes the drainage opening when the float component rises, eliminating the need for manual sealing pad operation. The system self-regulates the drainage process through buoyancy-driven float movement, reducing human intervention and associated leakage risks from improper sealing pad closure.
Solution Approach 2:
The patent replaces the mechanical sealing pad closure mechanism with a soft touch valve body that responds to float position. This substitution eliminates the need for manual operation of sealing pads and reduces leakage by using a more reliable soft seal mechanism that automatically engages based on water level.
3Adaptability or versatility
If two sealing pads are closed for high and low drainage volume, then flow control is achieved, but operation becomes complicated
Solution Approach 1:
The system automatically controls drainage volume through the float component rising and falling based on water level. The adjusting component and control component enable users to preset high and low drainage volumes, after which the system self-regulates without requiring manual operation of sealing pads or complex controls during actual use.
Solution Approach 2:
The patent allows users to adjust and preset the desired drainage volumes beforehand using the adjusting component and control component. Once preset, the system automatically executes the predetermined high or low drainage volume operation, eliminating the need for complex manual intervention during actual drainage operations.
4Manufacturing precision
If the flowing passage size is adjusted, then drainage volume control is improved, but the control mechanism becomes more complex
Solution Approach 1:
The control component serves multiple functions: it adjusts the cross-section of the flowing passage, controls the water flow into the float chamber, and works in conjunction with the float component to achieve both high and low drainage volume control. This multi-functionality reduces the need for separate complex control mechanisms for each function.
Solution Approach 2:
The patent combines the adjusting component and control component into an integrated system where both components work together to control the drainage volume. The control component merges the functions of passage adjustment and flow control, reducing overall system complexity while maintaining precise drainage volume control.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The mechanism provides stable and adjustable double flow drainage with simple operation, reducing leakage and enhancing applicability by allowing for precise control of drainage volumes through the adjustment of flowing passages and switch elements.
Implementation Method 1
a float component, wherein the float component can move with relative to the base (10) to open and close the drainage opening (11)
Implementation Method 2
water enters the float (110) through the smaller flowing passage to drain a first drainage volume of water; water enters the float (110) through the larger flowing passage to drain a second drainage volume of water

AI summary
A double flow control mechanism of a soft touch drain valve and a double flow control method, includes a base, a float component and a starting component. The base is assembled with a valve body. The float component is has a flowing passage and can move relative to the base to open and close the drainage opening. The flowing passage connects the inside and the outside of the float chamber of the float component. The starting component controls the size of the flowing passage. The first starting switch can open a smaller flowing passage of the float component; the resultant force drains a first drainage volume of water. The second starting switch can open a larger flowing passage of the float component; the resultant force drains a second drainage volume of water.
