Flush Actuator Assembly with Variable Displacement Relief Post
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flush valve designs lack the ability to adjust and control the quantity of water used for each flush, leading to inefficient water usage and a constant flush cycle.
Innovation Solution
A flush actuator assembly with a valve actuator having a high rim and a low rim, allowing for different displacement distances of the relief valve post, enabling the selection between a full flush and a reduced flush cycle by moving the actuator in different directions, which varies the duration of the flush cycle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional flush actuator assembly is used, then the flush valve operates with a constant flush cycle, but the quantity of water used for each flush cannot be adjusted or controlled
Solution Approach 1:
The actuator assembly is designed with movable components including a plunger rod that can be displaced in different directions (first and second directions) to dynamically adjust the separation distance of the relief valve post, enabling variable flush quantities while maintaining a relatively simple overall structure
Solution Approach 2:
The invention changes the separation distance parameter between the relief valve post and valve seat by displacing the plunger rod in different directions, thereby controlling the quantity of water flushed. This parameter adjustment is achieved through a simple mechanical actuator design rather than complex control systems
2Adaptability or versatility
If the relief valve post is displaced by a fixed distance, then the valve operation is simple, but the flush cycle duration and water consumption cannot be varied
Solution Approach 1:
The plunger rod can be displaced dynamically in either a first direction or a second direction to achieve different separation distances of the relief valve post, enabling variable flush cycle durations while maintaining simple operational control through directional displacement
3Loss of substance
If a single separation distance is used for the relief valve post, then the device structure is simple, but water conservation cannot be optimized
Solution Approach 1:
The actuator assembly enables dynamic adjustment of the relief valve post separation distance by displacing the plunger rod in different directions, allowing optimization of water consumption for different flush conditions while maintaining a relatively simple mechanical structure without complex control systems
Solution Approach 2:
The invention optimizes water consumption by changing the separation distance parameter between the relief valve post and valve seat through simple directional displacement of the plunger rod, enabling water conservation without requiring complex adjustment mechanisms
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
Enables adjustable water usage by allowing users to choose between a full flush and a reduced flush, optimizing water consumption based on needs, and can be easily retrofitted into existing systems.
Implementation Method 1
water pressure in the valve inlet 12 is communicated to the upper chamber 24 through the by-pass 26 defined in the diaphragm 22. Because the surface area which is subjected to water pressure is greater on the upper side of the diaphragm 22, the water pressure forces the diaphragm down onto the sealing end 21 of the barrel section 18

AI summary
A flush actuator assembly for use with a flush valve having a relief post is disclosed. The flush actuator assembly includes a valve actuator having a first end, a second end, and an aperture extending therebetween. The aperture is adapted to surround at least a portion of the relief valve post. Movement of the valve actuator in a first direction engages the relief valve post at a first location on the post and displaces the relief valve post by a first separation distance. Movement of the valve actuator in a second direction engages the relief valve post at a second location on the post and displaces the relief valve post by a second separation distance. The first separation distance and the second separation distance are different.
