Solution Overview

Problem

Users often fail to notice the scale line on an absorber canister when filling it with absorbent, leading to excessive absorbent being added, which prevents the canister lid from closing properly.

Innovation Solution

An absorber canister with an elastic component in the accommodating chamber, allowing the volume to increase when the canister lid is closed, enabling proper closure even with excessive absorbent.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If a scale line is provided on the canister body to indicate the maximum fill level, then the guidance for proper filling is improved, but users still frequently fail to notice it and overflow the absorbent, causing the lid to close improperly

Engineering Contradiction:

Improvevisibility of scale lineVSAvoidease of filling absorbent

Core Design Contradiction:

Loss of informationVSEase of operation

Solution Approach 1:

The scale line is designed with a color contrast that makes it visually distinct against the canister body background. This color change principle enhances the visibility and attention-grabbing effect of the scale line, making it more likely to be noticed by users during the filling process.

Inventive Principle:

Principle #32Color changes

Solution Approach 2:

The scale line is pre-marked on the canister body before use, providing advance visual guidance to users on the correct fill level. This preliminary visual instruction is intended to prevent overfilling before it occurs, though the patent acknowledges users may still overlook it.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If the canister lid is designed to close tightly to maintain sealing performance, then the sealing reliability is improved, but excessive absorbent prevents proper closure

Engineering Contradiction:

Improvesealing performanceVSAvoidease of closing lid

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The canister lid is designed with dynamic closing characteristics that allow it to adapt to varying absorbent levels. When absorbent is present, the lid can close with appropriate force while accommodating the volume, maintaining sealing performance without requiring excessive precision in the closing action.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The lid closing mechanism incorporates a cushioning effect that allows for minor variations in absorbent volume. This beforehand cushioning design ensures that even if absorbent levels are slightly elevated, the lid can still close properly without compromising sealing, as the closing force is designed to accommodate small volume variations.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

3Device complexity

If the accommodating chamber volume is fixed to maintain simple structure, then the device complexity is reduced, but excessive absorbent cannot be accommodated, requiring removal

Engineering Contradiction:

Improvestructure simplicityVSAvoidadaptability to absorbent volume

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The accommodating chamber volume is designed to be variable rather than fixed. The chamber can expand its effective volume when absorbent is added, allowing the canister to adapt to different fill levels without requiring structural complexity or absorbent removal. This parameter change capability is achieved through the interaction between the lid closing force and the absorbent volume.

Inventive Principle:

Principle #35Parameter changes
