Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tap dispensers face challenges in achieving high flow rates, particularly for highly viscous fluids, while maintaining effective sealing to prevent flow once dispensing is complete, and often require complex tools for tamper evidence.
Innovation Solution
A tap dispenser design featuring a spring button and valve system with a flexible seal, a larger sealing surface diameter, and optimized guide supports to minimize flow resistance, combined with an anti-tamper cap for user-friendly tamper evidence, enhances flow rates and sealing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the valve sealing surface diameter is increased to improve sealing reliability, then sealing effectiveness is improved, but flow resistance increases and flow rate decreases
Solution Approach 1:
The patent optimizes the valve sealing surface diameter to a specific range (0.6 inches to 1.2 inches) to achieve the best balance between sealing effectiveness and flow rate. This parameter optimization allows the valve to maintain reliable sealing while minimizing flow resistance, resolving the contradiction between sealing reliability and productivity.
2Device complexity
If guide supports are positioned below the channel portion lower wall, then structural simplicity is maintained, but flow resistance increases and flow rate decreases
Solution Approach 1:
The patent repositions the guide supports from below the channel portion lower wall to above it, utilizing the vertical dimension to optimize fluid flow. This dimensional change allows the guide supports to better align with the fluid flow path, reducing turbulence and flow resistance while maintaining structural simplicity, thus improving flow rate without significantly increasing device complexity.
3Reliability
If a complex tamper evidence mechanism is used to provide reliable tamper evidence, then tamper evidence reliability is improved, but device complexity and ease of operation worsen
Solution Approach 1:
The patent extracts the tamper evidence function from a complex mechanical mechanism and implements it through a simple anti-tamper cap with tamper-evident features. This extraction approach provides reliable tamper evidence while maintaining device simplicity and ease of operation, as the cap can be easily removed and its removal is visibly evident without requiring complex mechanisms.
4Ease of manufacture
If the valve stem guide is positioned below the channel portion lower wall, then manufacturing simplicity is maintained, but flow resistance increases
Solution Approach 1:
The patent repositions the valve stem guide from below the channel portion lower wall to above it, utilizing the vertical dimension to optimize both manufacturing and flow characteristics. This repositioning allows for straightforward manufacturing processes while simultaneously improving fluid flow by reducing resistance and turbulence in the dispensing channel.
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
The design significantly increases flow rates for viscous liquids and ensures reliable sealing, while the anti-tamper cap provides evidence of container use without requiring special tools.
Implementation Method 1
The spring button is compressed when the valve is in the open position and extends when the valve is in the closed position
Implementation Method 2
the valve body is in contact with the valve sealing surface preventing fluid from flowing out of the dispensing portion

AI summary
A tap dispenser assembly for use with a fluid container including a tap body, a spring button, and a valve. The tap body includes an attachment portion, a dispensing portion, and a fluid channel with an upper wall and a lower wall. The dispensing portion includes a valve stem guide and a guide support. The guide support is above the lower wall and/or the upper wall. The valve is connected to the spring button and is slidingly inserted into the valve stem guide. The tap dispenser assembly has a closed position where the spring button is not depressed and the valve seals the dispensing portion and an open position where the spring button is depressed and the seal between the valve and dispensing portion is broken, allowing fluid to flow from the tap dispenser assembly.
