Dual Draw Stick Container Insert for Multiple Dilutions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container inserts with a single draw stick limit the ability to provide multiple dilutions from a single chemical container, requiring separate containers for different dilutions.
Innovation Solution
A dual draw stick container insert with a valve system that creates two separate flow channels from a single chemical container, using concentric flow channels and plastic components to enable accurate dilutions at varying flow rates without the risk of chemical reactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single draw stick is used in the container insert, then the structure is simple, but only one dilution can be provided requiring separate containers for different dilutions
Solution Approach 1:
The container insert is segmented into multiple flow channels, each with its own draw stick (first and second draw sticks). This segmentation allows different dilutions to be drawn simultaneously from separate channels while maintaining a unified insert structure that fits within the container.
Solution Approach 2:
The first and second draw sticks are nested within the container insert housing, with each draw stick positioned in its own dedicated channel. The draw sticks can be concentric or parallel, with one potentially positioned inside or alongside the other, maximizing space utilization while providing multiple independent flow paths.
2Adaptability or versatility
If multiple draw sticks are used to provide multiple dilutions, then versatility improves, but the device complexity increases
Solution Approach 1:
Multiple draw sticks and their associated components are merged into a single integrated container insert assembly. The first and second draw sticks, along with their respective metering tips and flow channels, are combined into one unit that replaces what would otherwise require multiple separate containers or complex multi-component systems.
Solution Approach 2:
The container insert is designed as a universal component that can provide multiple dilutions through a single device. The insert incorporates multiple flow channels with different metering capabilities, allowing it to perform the function of multiple separate containers while maintaining a standardized interface for the chemical container.
3Reliability
If separate containers are used for different dilutions, then each dilution can be optimized, but the number of containers and potential chemical reactions increase
Solution Approach 1:
The single chemical container is served by multiple segmented flow channels within the insert, each channel providing a dedicated path for a specific dilution. This segmentation allows multiple dilutions to be obtained from one container without requiring multiple separate chemical containers, thereby reducing the risk of cross-contamination and chemical reactions between different substances.
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
Enables accurate and efficient dispensing of multiple dilutions from a single container, eliminating the need for separate containers and reducing the risk of chemical reactions, while being completely recyclable.
Implementation Method 1
An elongated and compressible tubular plastic spring, having an upper end and a lower end, with the lower end of the spring being positioned on the body portion of the disc member and with the upper end of the spring being in engagement with the lower end of the third annular shoulder of the valve stem. The spring yieldably urges the valve stem to its upper closed position.
Implementation Method 2
a ring-shaped and flat liner having perforations formed therein which prevent liquid from passing therethrough but which permit air to pass therethrough
