Integrated Suction Lance Canister for Residue-Free Fluid Emptying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suction systems for emptying canisters leave residual substances and pose health risks due to potential contact with the remaining substance, especially when handling empty canisters.
Innovation Solution
A suction system with a canister integrated suction lance and a connector closure that allows for separate sealing and venting of openings, ensuring complete emptying and safe handling by maintaining a closed system during extraction and disposal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a separate suction lance is used to empty the canister, then the substance can be extracted, but residual substance remains in the canister and manual handling is required
Solution Approach 1:
The suction lance is integrated directly into the canister body as a fixed component, merging two previously separate elements (canister and suction lance) into one unified structure. This eliminates manual insertion and handling of the suction lance while ensuring consistent positioning for complete substance extraction without residues.
2Quantity of substance
If the canister is opened for substance extraction, then the substance can be removed, but health risks arise from potential contact with remaining substance
Solution Approach 1:
The connector closure is divided into separate sealing elements that independently seal the filling opening and the suction opening. This segmentation allows the suction opening to remain sealed during substance extraction while the filling opening is sealed separately, maintaining a closed system that prevents health risks from substance contact.
Solution Approach 2:
The connector closure acts as an intermediary component that maintains a closed connection between the suction device and the canister during substance extraction. This intermediary seal prevents direct contact between the operator and the substance, eliminating health risks while enabling complete substance removal.
3Device complexity
If a single opening is used for both filling and suction, then the design is simpler, but the openings cannot be sealed independently
Solution Approach 1:
The single opening is segmented into two separate openings (filling opening and suction opening), each with its own sealing element in the connector closure. This segmentation enables independent sealing of each opening, providing versatility for different operational modes while maintaining a relatively simple overall design.
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 system enables complete and residue-free emptying of canisters, reducing health risks by eliminating the need for manual handling of the suction lance and preventing substance contact during emptying and disposal.
Implementation Method 1
a suction lance for sucking the substance out of the body of the canister
Implementation Method 2
a venting means for venting the inside of the body of the canister, wherein the suction lance is formed integrally as part of the body of the canister
