Two-Piece Valve Dispensing System for Leak-Free Viscous Fluid Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensing systems for viscous fluids, such as laundry detergents, face issues like leakage, force requirements, messiness, and complexity, particularly with press-tap systems, which are not user-preferred due to their operational complexity and inefficiencies.
Innovation Solution
A two-piece dispensing system comprising a body and a valve with an integrated cup-spring mechanism and actuation button, allowing for controlled fluid flow through a liquid-tight seal that can be easily activated and deactivated, along with optional features like an on/off toggle and vent systems to prevent dripping and improve usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If press-tap systems are used for dispensing viscous fluids, then fluid can be dispensed under gravitational forces, but leakage and messiness occur due to improper sealing and control
Solution Approach 1:
The patent extracts the sealing function from the traditional press-tap valve by introducing a separate stop member that forms a liquid-tight seal with the interior wall of the body. This separation allows the valve to control flow while the stop member ensures sealing, preventing leakage and messiness during dispensing operation.
Solution Approach 2:
The dispensing system is segmented into distinct functional components: a valve for flow control, a stop member for sealing, and a spring for actuation. This segmentation allows each component to perform its specific function optimally, with the valve handling flow regulation and the stop member preventing leakage, thereby resolving the contradiction between ease of operation and prevention of harmful factors.
2Device complexity
If traditional valve mechanisms are used, then fluid flow can be controlled, but the system becomes complex and requires multiple steps for dosing
Solution Approach 1:
The patent merges the valve and stop member into a single integrated assembly where the stop member is positioned within the body and works in conjunction with the valve. This integration reduces the number of separate components and steps required for dosing, simplifying the overall system while maintaining flow control capability, thus resolving the contradiction between device complexity and dosing time.
Solution Approach 2:
The spring-loaded stop member automatically returns to its sealing position after dispensing, eliminating the need for manual resetting or multiple操作步骤. The system performs the sealing action automatically through the spring mechanism, reducing the number of steps required for dosing and simplifying the overall operation.
3Ease of operation
If force is applied to actuate the press-tap valve, then fluid flow is initiated, but excessive force requirements make operation difficult
Solution Approach 1:
The spring acts as an intermediary between the user's actuation force and the valve mechanism. The spring stores and releases energy to assist in opening and closing the valve, reducing the peak force required from the user. This intermediary mechanism makes valve actuation easier while maintaining effective flow control, resolving the contradiction between ease of operation and actuation force requirements.
