Solution Overview

Problem

Existing canister emptying devices often leave residual substances due to inconsistent suction lance positioning, posing health risks during handling, especially when dealing with hazardous materials.

Innovation Solution

A canister design with an integrally formed suction lance that ensures the lower end is always positioned at the lowest point, combined with a connector closure system for safe and residue-free extraction, eliminating the need for manual handling and reducing leakage risks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a separate suction lance is used that is inserted into the canister, then the suction lance can be removed for cleaning or replacement, but the positioning of the suction lance inside the canister is inconsistent every time a canister is used, leaving residual substance

Engineering Contradiction:
Improveconsistent suction lance positioningVSAvoidseparate suction lance component
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The suction lance is merged with the canister body to form an integral one-piece structure. The lower end of the suction lance is formed directly as part of the canister body, eliminating the need for separate insertion and ensuring consistent positioning at the lowest point of the canister interior for complete substance removal.

Inventive Principle:
Principle #5Merging (Combining)

2Object-affected harmful factors

If manual handling of the suction lance is required for insertion and removal, then the suction lance can be positioned correctly, but there is risk of unintended contact with substance and potential health risks

Engineering Contradiction:
Improvecontact with hazardous substanceVSAvoidmanual handling of suction lance
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

By integrating the suction lance into the canister body, the system eliminates the need for manual insertion and handling of a separate suction lance. The integral design ensures the suction lance remains in the canister during transport and use, reducing handling steps and minimizing exposure risk to hazardous substances.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated suction lance design allows the canister to be self-sufficient for substance removal without requiring external manipulation of the suction lance. The suction opening is automatically positioned at the lowest point through the integral design, eliminating the need for manual positioning operations.

Inventive Principle:
Principle #25Self-service

3Quantity of substance

If the suction lance reaches to the bottom of the canister, then complete emptying is achieved, but the suction lance may contact residue at the bottom that is difficult to remove

Engineering Contradiction:
Improveresidue-free emptyingVSAvoidcontact with residue
Core Design Contradiction:
Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The suction lance is formed as an integral part of the canister body, with its lower end positioned at the lowest point of the canister interior. This ensures the suction opening is always at the optimal position for complete substance removal while eliminating manual contact with residue through the closed system design.

Inventive Principle:
Principle #5Merging (Combining)
