Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for removing excess solution from cleaning and sanitizing dispensers have long drainage times, large footprints, and are complex and costly, making them inefficient and difficult to manufacture, and they do not effectively protect sensitive components from chemical exposure.
Innovation Solution
A small footprint, single piece three-way elastomeric valve system that automatically drains excess solution by using a moveable wall to seal and open a drainage path, minimizing exposure to chemical solutions and allowing for quick and efficient drainage, with a fluoroelastomer material for chemical resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If current automatic drainage systems are used, then excess solution is removed, but drainage time becomes long
Solution Approach 1:
The drainage system is segmented into multiple drainage paths with multiple valves (first valve, second valve, third valve) that can operate independently or in combination, allowing parallel drainage operations to increase overall drainage speed while reducing total drainage time
Solution Approach 2:
The system uses dynamic valve control where valves transition between open and closed states based on operational requirements. The first valve opens to drain solution from the first region, the second valve drains the second region, and the third valve provides additional drainage capacity, creating a dynamic multi-stage drainage process that accelerates fluid removal
2Productivity
If large footprint drainage systems are used, then drainage capacity is sufficient, but device size increases
Solution Approach 1:
The drainage valves are nested within the dispenser structure, with valve housings integrated into the existing device architecture. The first valve, second valve, and third valve are positioned in nested or adjacent configurations that utilize vertical space and existing structural voids, maintaining high drainage capacity while minimizing the horizontal footprint
Solution Approach 2:
The drainage system transitions from horizontal expansion to vertical integration, with valves arranged in a multi-level configuration. The first valve drains from an upper region, the second valve from a lower region, and the third valve provides additional capacity, utilizing the vertical dimension to achieve high drainage capacity without increasing horizontal footprint
3Productivity
If complex drainage systems are used, then drainage effectiveness is improved, but manufacturing complexity increases
Solution Approach 1:
Multiple valve functions are merged into a single integrated drainage assembly. The first valve, second valve, and third valve are combined in a unified structure with shared housing and coordinated actuation mechanisms, achieving effective multi-region drainage while simplifying manufacturing through integrated production rather than separate assembly of multiple independent components
Solution Approach 2:
The drainage system uses universal valve designs that can handle different fluid flow conditions and regions. The valves are designed with standardized components and interchangeable parts, allowing the same basic valve design to serve multiple drainage functions, thereby reducing manufacturing complexity while maintaining drainage effectiveness across different operational scenarios
4Productivity
If complex drainage systems are used, then drainage performance is improved, but manufacturing cost increases
Solution Approach 1:
Multiple valve functions are merged into a single integrated drainage assembly that can be manufactured as one piece or pre-assembled unit, reducing the number of separate components that need to be sourced, inventoried, and assembled. This integration lowers manufacturing costs while maintaining the drainage performance achieved through multiple valve stages
Solution Approach 2:
The drainage system incorporates self-regulating features where the valves automatically open and close based on pressure differentials and fluid flow conditions without requiring external control mechanisms. This self-service operation eliminates the need for complex control systems, sensors, and actuators, thereby reducing manufacturing costs while maintaining effective drainage performance
5Object-affected harmful factors
If sensitive components are exposed to solution, then chemical compatibility issues arise, but protection mechanisms increase complexity
Solution Approach 1:
Sensitive components are extracted from the solution-exposed regions and placed in protected zones. The valve assembly creates distinct separated zones where solution flows through designated drainage paths away from sensitive components, eliminating the need for complex protection mechanisms while preventing chemical exposure through spatial separation

AI summary
A drainage component in fluid communication with the fluid supply line includes a drain channel leading to a drain, the drain channel having an inner wall and an outer wall. The inner wall has a sealing surface approximate a three-way elastomeric valve. The elastomeric valve includes a moveable first wall having a first position when the fluid supply is on and a second position when fluid supply is off and a second wall connected to the moveable first wall, the second wall engaging a drain sealing surface when the first wall is in the first position. The elastomeric valve includes an orifice through which fluid may flow. When the pressure of the fluid on the elastomeric element increases, the second wall of the elastomeric valve engages the drain sealing surface. The elastomeric valve is preferably a fluoroelastomer to ensure both flexibility and resistance to a variety of chemical products.
