Variable Drop Start Timing Mechanism for Adjustable Flush Water Volume
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional discharge valve apparatuses have a fixed opening time for the discharge port, limiting the ability to adjust flush water volume according to different toilet types, and there is a need for a solution that allows for adjustable flush water volume to accommodate varying toilet requirements, especially with the trend towards water conservation.
Innovation Solution
A discharge valve apparatus with a variable drop start timing mechanism, which includes a buoyancy adjustment mechanism on the float, allowing the timing of the valve body's drop to be changed, enabling adjustable flush water volume discharge by altering the buoyancy through a reservoir portion and adjustment portion, allowing the apparatus to be adaptable to various toilet types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the discharge valve apparatus uses a fixed opening time for the discharge port, then the structure is simple and reliable, but the flush water volume cannot be adjusted according to different toilet types
Solution Approach 1:
The patent applies the dynamics principle by making the float's buoyancy adjustable rather than fixed. The float includes a variable drop start timing mechanism that can change its buoyancy characteristics, allowing the discharge valve to adapt to different toilet types by adjusting when the float drops and opens the discharge port. This transforms a static system into a dynamically adjustable one.
Solution Approach 2:
The patent implements parameter changes by modifying the buoyancy parameter of the float through the variable drop start timing mechanism. By changing the buoyancy parameter, the system can adjust the timing of the valve body drop and consequently control the flush water volume, enabling adaptability to different toilet types without fundamentally changing the overall structure.
2Adaptability or versatility
If the flush water tank size is increased to enable adjustment of flush water volume, then the flush water volume can be adjusted, but the device complexity and space requirement increase
Solution Approach 1:
Instead of changing the physical size of the flush water tank, the patent changes the operational parameters of the discharge valve apparatus. By adjusting the buoyancy of the float through the variable drop start timing mechanism, the system can control the timing and duration of water discharge, thereby adjusting the flush water volume without modifying the tank's physical dimensions.
Solution Approach 2:
The patent uses dynamic adjustment of the float's buoyancy characteristics to control flush water volume. This allows the same fixed-size tank to provide variable flush volumes by changing when the discharge valve opens and how long it remains open, avoiding the need for multiple tanks of different sizes.
3Reliability
If the discharge valve apparatus is designed for a specific flush water amount, then the structure is optimized for that purpose, but it cannot be applied to other types of toilets with different flush water requirements
Solution Approach 1:
The patent maintains structural optimization for reliable operation while adding the capability to change the buoyancy parameter of the float. This allows the discharge valve apparatus to be optimized for performance in its basic configuration while also being adaptable to different toilet types through parameter adjustment, rather than requiring different designs for different applications.
Solution Approach 2:
The patent creates a universal discharge valve apparatus that can serve multiple toilet types. By incorporating the variable drop start timing mechanism in the float, a single device design can be adapted to different flush water requirements, making the apparatus multi-functional and universally applicable across different toilet configurations.
