Sliding Plug Dispensing Fitment for Universal Fluid Containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensing systems lack a universal design for connectors, making it difficult to switch between different types of fluid containers, and often contain non-recyclable metal components that complicate safety and recycling procedures.
Innovation Solution
A dispensing fitment assembly with a slidingly movable plug and a dispensing probe that can be easily engaged and disengaged to allow fluid communication, featuring a universal design and recyclable materials to facilitate use with various container shapes and sizes, while preventing user exposure to fluids.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If connectors are sized and shaped according to specific container types, then fluid dispensing function is ensured, but adaptability to different container types is reduced
Solution Approach 1:
The connector is designed with a universal interface that can accommodate multiple container types (rigid bottles, flexible bags, inverted containers, upright containers) through a standardized coupling mechanism, allowing one connector design to perform multiple functions across different container configurations
2Reliability
If metal springs and valves are used in connectors, then fluid control function is improved, but environmental friendliness and recyclability are reduced
Solution Approach 1:
The metal spring component is completely removed from the connector design. Fluid control is achieved through alternative mechanisms such as diaphragms, flaps, or elastic membranes made from recyclable materials, extracting the problematic metal spring while maintaining the essential fluid control function
Solution Approach 2:
The material composition of the connector is changed from including metal components to being entirely composed of recyclable polymers or elastomers. This parameter change in material selection maintains functional performance while improving environmental compatibility and recyclability
3Manufacturing precision
If connectors include multiple components, then fluid control precision is improved, but ease of operation and safety are reduced
Solution Approach 1:
Multiple separate components (body, cap, valve mechanism) are merged into an integrated single-piece or few-piece connector assembly. This reduces the number of parts users must handle and assemble, improving ease of operation while maintaining fluid control precision through integrated design features
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 solution provides a user-friendly, environmentally friendly dispensing system that can be used with various container orientations and types, ensuring safe operation and easy recycling by eliminating metal components and allowing for controlled fluid flow.
Implementation Method 1
The engagement between the dispensing probe and the interior surface of the plug is configured to move the plug from the closed position to the open position. The dispensing probe is disengageable from the interior surface of the plug, and the disengagement between the dispensing probe and the interior surface of the plug configured to move the plug from the open position to the closed position.
