Gravity-Actuated Tap Plunger Sealing for Leakage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional self-closing gravity-actuated taps are not suitable for locations without centralized water systems, are prone to leakage during transport, and require electrical power, making them unreliable and costly, and they do not efficiently dispense water in low-pressure applications or remote areas.
Innovation Solution
A gravity-actuated tap design featuring a plunger with varying cross-sectional sealing surfaces and a connector for attaching to containers, allowing for efficient dispensing of flowable materials without the need for a centralized water supply, with a mechanism that forms seals to prevent leakage and allows easy installation on non-vertical surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional self-closing gravity-actuated taps are used in locations without centralized water systems, then water dispensing is enabled, but leakage occurs during transport
Solution Approach 1:
The tap is divided into separate modular components including a body, plunger, and connector that can be assembled on-site. This segmentation allows the tap to be designed specifically for remote locations while preventing leakage during transport through careful sealing at each interface.
Solution Approach 2:
A connector component serves as an intermediary between the tap body and the water source container, creating a reliable seal that prevents leakage during transport and installation in remote locations without centralized water systems.
2Reliability
If conventional self-closing taps with multiple parts are used, then water dispensing function is achieved, but reliability decreases and cost increases
Solution Approach 1:
Multiple functional components are merged into integrated assemblies, such as combining the sealing mechanism and plunger into a unified structure. This reduces the total number of parts while maintaining reliability through fewer potential failure points and simpler assembly.
3Reliability
If electrical water taps with self-closing valves are used, then water waste is minimized, but complexity and requirement for electrical power source increase
Solution Approach 1:
The electrical control system is replaced with a purely mechanical gravity-actuated mechanism. The self-closing function is achieved through gravitational force acting on a plunger that opens and closes valves mechanically, eliminating the need for electrical power sources while maintaining water conservation benefits.
4Ease of operation
If conventional taps without self-closing properties are used in locations with scarce water, then ease of operation is improved, but water efficiency decreases
Solution Approach 1:
The tap incorporates a self-closing mechanism that automatically closes the water flow after dispensing, eliminating the need for continuous manual operation. This self-service feature prevents water waste while maintaining ease of operation through simple gravitational actuation without requiring complex controls.

AI summary
A tap for dispensing flowable materials. The tap includes a body and a plunger positioned within a channel in the body. The plunger is movable between first, second, and third positions. The plunger and the body form a first seal when the plunger is in the first position, and a second seal when the plunger is in the second position. Flowable material may pass through the channel when the plunger is the third position. The tap also includes a connector to sealingly engage the body with a flowable material source and establish fluid communication between the flowable material source and the channel.
