Bottle Extraction Head With Disposable Tube Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing removal systems for fluids from bottles suffer from leak-tight seal issues, allowing vapor escape and contamination between bottles, and expose users to residual fluids.
Innovation Solution
A removal system with an extraction head that forms a hermetically sealed unit using a mounted tube, featuring a releasable actuation mechanism to prevent contamination and ensure a new tube is used for each bottle, employing a mechanical locking mechanism with balls and a guide channel for secure and efficient tube management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a simple lid design with a bore hole is used for the extraction head, then the device complexity is reduced and ease of manufacture is improved, but the seal reliability deteriorates allowing vapor escape
Solution Approach 1:
The extraction head is divided into separate functional components: a reusable extraction head body and disposable tubes with integrated seals. This segmentation allows the complex sealing function to be isolated in the disposable tube component, maintaining reliability while keeping the main extraction head simple and easy to manufacture.
Solution Approach 2:
The patent employs disposable tubes that are discarded after a single use. These tubes incorporate pre-formed seals and are replaced for each new bottle, ensuring consistent seal reliability without requiring complex reusable sealing mechanisms in the extraction head itself.
2Productivity
If the tube is pulled out of the empty bottle for reuse, then the productivity is improved by reusing the same tube, but the contamination risk increases as fluid residues adhere to the tube
Solution Approach 1:
The tube is designed as a disposable component that is discarded after use with one bottle. This eliminates contamination risks from fluid residues adhering to the tube, as each new bottle receives a fresh, clean tube. The low cost of the disposable tube makes this approach economically viable despite reduced reuse.
Solution Approach 2:
The system implements a discard approach for the tube rather than attempting to clean and recover it. The tube is intentionally designed for single-use and disposal, simplifying the process by eliminating complex cleaning procedures while ensuring no cross-contamination between bottles.
3Ease of operation
If the tube is pulled out of the bottle by the user, then the operation flexibility is improved, but the user safety deteriorates due to exposure to adhering fluid
Solution Approach 1:
By making the tube disposable and integrating it with the extraction head, the system eliminates the need for users to manually handle and remove contaminated tubes. The entire assembly can be discarded or replaced as a unit, preventing user exposure to harmful fluids while maintaining operational flexibility.
Solution Approach 2:
The harmful element (contaminated tube) is extracted and isolated in the disposable component that can be easily removed and discarded as a complete unit. This separates the contamination risk from the user, allowing flexible operation without safety compromises.
