Solution Overview

Problem

Traditional cylindrical tins for storing surface coatings are inefficient for use with rollers, generate significant waste, and have cumbersome disposal issues, while alternative packaging solutions often face usability and filling difficulties.

Innovation Solution

A deformable packaging apparatus with an access region and a one-way inlet valve allows efficient filling and easy access, reducing waste and eliminating the need for intermediary trays, with a deformable plastic material ensuring long-term storage and easy disposal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of substance

If standard cylindrical tins are used for storing surface coatings, then the packaging provides structural stability and ease of manufacture, but the packaging generates significant waste and creates disposal problems

Engineering Contradiction:
Improvewaste generationVSAvoidpackaging manufacturing
Core Design Contradiction:
Loss of substanceVSEase of manufacture

Solution Approach 1:

The patent uses a flexible pouch instead of a rigid tin container. The pouch is made from flexible plastic material that can be easily manufactured and disposed of, while still providing adequate protection for the surface coating. This flexible packaging dramatically reduces waste compared to traditional metal tins.

Inventive Principle:
Principle #30Flexible shells and thin films

2Ease of operation

If traditional tins are used for surface coating storage, then the packaging provides long-term storage stability, but the packaging is too small to allow roller insertion and requires intermediary trays

Engineering Contradiction:
Improveroller accessVSAvoidpackaging structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The pouch is designed to be deformable and expandable. As surface coating is removed from the pouch, the pouch naturally deforms and can be squeezed to control the flow of coating material. This dynamic behavior allows easy access with rollers without requiring rigid structural support or intermediary trays.

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If the packaging is designed with easy access for users, then the packaging allows simple opening and use, but the packaging becomes difficult to seal and store after opening

Engineering Contradiction:
Improveaccess to surface coatingVSAvoidresealability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The pouch design allows users to open the pouch by tearing or cutting the seal, then squeeze the pouch to control paint flow directly. After use, the pouch can be resealed by folding the opening back and securing it, allowing the remaining paint to be stored without special sealing mechanisms.

Inventive Principle:
Principle #25Self-service

4Productivity

If the packaging allows efficient filling, then the packaging can be filled without modification of existing filling lines, but the packaging must maintain structural integrity during filling

Engineering Contradiction:
Improvefilling efficiencyVSAvoidpackaging structural integrity
Core Design Contradiction:
ProductivityVSStrength

Solution Approach 1:

The flexible pouch can be filled through a simple inlet that accommodates standard filling equipment. The flexible material allows the pouch to expand during filling without requiring rigid structural support, while still maintaining adequate strength to contain the surface coating.

Inventive Principle:
Principle #30Flexible shells and thin films

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 deformable packaging apparatus provides efficient, waste-reducing storage and application of surface coatings without additional mess or waste, maintaining the coating until use and minimizing environmental impact.

Implementation Method 1

the inlet comprises an inlet valve for receiving said surface coating into the internal volume and for preventing said surface coating from flowing out of the internal volume through the inlet valve

Methodology Applied
Scientific EffectOne-way valve mechanism: Valve

Implementation Method 2

the inlet comprises a cap to seal the inlet. The cap may have an internal thread configured to engage with an associated external thread on a body of the valve to hold the cap in position

Methodology Applied
Scientific EffectMechanical sealing: Mechanical Fastener

Implementation Method 3

The deformable body may be formed from a deformable plastic material. The deformable plastic material would not be likely to degrade over time which would mean that the surface coating would be retained in the internal volume until the deformable body is opened by a user

Methodology Applied
Scientific EffectMaterial degradation resistance:
