T-Shaped Dispensing Tap With Concealed Cam Actuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensing taps for liquid containers, particularly those with T-shapes, are complex, prone to debris accumulation, and require multiple parts, making them difficult to actuate and maintain.
Innovation Solution
A two-piece dispensing tap with a T-shaped body and a cap or knob, featuring camming protrusions and grooves that allow for easy actuation in less than one full turn, concealed camming mechanisms, and a simple, two-piece construction with a continuous surface for easy assembly and reduced debris accumulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple parts are used to form the valve cap and camming mechanism, then the valve can be actuated, but the device complexity increases and debris accumulation is promoted
Solution Approach 1:
The patent combines the valve cap and camming mechanism into a single integrated component. The cap includes an integrated camming surface that directly engages with the valve stem, eliminating the need for separate camming components. This merging reduces the number of parts while maintaining the valve actuation function, directly resolving the contradiction between ease of operation and device complexity.
Solution Approach 2:
The valve cap serves multiple functions: it seals the valve opening, provides the camming action for actuation, and acts as a user interface for operation. By making the cap multi-functional, the patent eliminates the need for separate dedicated camming components, reducing overall device complexity while preserving operational capability.
2Ease of operation
If multiple parts and exposed camming mechanisms are used, then the valve can be actuated, but debris accumulation increases and maintenance difficulty increases
Solution Approach 1:
By integrating the camming mechanism into the cap structure, the patent creates a smooth, continuous surface without exposed joints or gaps where debris could accumulate. The camming surface is formed as part of the cap's outer surface, eliminating crevices that would trap particles and facilitate easy cleaning.
Solution Approach 2:
The cap is designed with a smooth, continuous outer surface that acts as a non-porous barrier, preventing debris from penetrating into internal mechanisms. The integrated design ensures no gaps or openings on the exterior surface, making the structure resistant to debris accumulation and easy to wipe clean.
3Ease of operation
If conventional screw threads are used for the camming mechanism, then the valve can be actuated, but more than one full turn is required reducing productivity
Solution Approach 1:
The camming surface is pre-configured with an optimized pitch angle that converts rotational motion into axial displacement more efficiently than conventional screw threads. The cam profile is designed to achieve full valve actuation within less than one full rotation, eliminating the need for multiple turns and improving operational speed.
Solution Approach 2:
The patent changes the geometric parameters of the threading mechanism by using a camming surface with a specific pitch angle rather than conventional screw threads. This parameter change allows the valve to be actuated more quickly with less than one full turn of the cap, directly improving productivity while maintaining ease of operation.
4Ease of manufacture
If a two-piece construction is used, then manufacturing is simplified, but the structural integrity may be compromised
Solution Approach 1:
The valve cap and camming mechanism are merged into a single monolithic component that is injection molded as one piece. This eliminates the need for assembly between multiple parts while maintaining structural integrity, as the integrated design removes potential weak points at joints and interfaces.
Solution Approach 2:
The patent uses a single material formulation for the integrated cap that combines the structural and functional requirements. The material is selected to provide both the necessary mechanical strength and the appropriate surface properties for camming action, ensuring structural integrity is maintained while simplifying manufacturing.

AI summary
A two piece, molded tap is contemplated. The tap is includes a T-shaped body with a rotatable cap serving as a valve element. Camming means are provided on opposing but concealed faces of the cap to enable the smooth and easy rotation of the cap between open and closed positions while rotating the cap less than one full revolution in comparison to the body which remains fixed to a flexible pouch or container.
