Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If plastic collation shrink film is used to bundle articles, then strong bundling force and stable structure are achieved, but environmental impact increases and production costs rise

Engineering Contradiction:
Improvebundling forceVSAvoidplastic material usage
Core Design Contradiction:
StrengthVSQuantity of substance

Solution Approach 1:

The connector flaps are designed to be detachably connected to articles, allowing the packaging to be easily disassembled and the articles to be recovered without damaging the packaging material, which can then be recycled

Inventive Principle:
Principle #34Discarding and recovering

Solution Approach 2:

The packaging uses a composite structure combining paperboard material with adhesive connectors, creating a strong yet environmentally friendly alternative to pure plastic packaging

Inventive Principle:
Principle #40Composite materials

2Stability of the object's composition

If plastic packaging film is heated for shrink wrapping, then articles are securely held in place, but articles may deform or become useless due to heat exposure

Engineering Contradiction:
Improvearticle positioning stabilityVSAvoidheat-induced deformation
Core Design Contradiction:
Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The invention replaces the thermal shrink wrapping process with a mechanical folding and adhesive bonding system. The connector flaps are folded around the articles and secured using adhesive, eliminating the need for heat exposure while maintaining secure article positioning

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

An adhesive intermediary is introduced between the connector flaps and the articles to achieve secure bonding without heat. The adhesive acts as a mediator that provides strong attachment while avoiding the harmful thermal effects of shrink wrapping

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If conventional plastic bundling is used, then articles are securely packaged, but fire risk increases due to heat exposure requirements

Engineering Contradiction:
Improvepackaging reliabilityVSAvoidfire risk
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The invention replaces the thermal process with a cold-process mechanical folding and adhesive bonding system, eliminating the heat source that creates fire risk while maintaining packaging reliability through the structural design of the connector flaps

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The packaging uses a disposable paperboard-based connector flap system that is safe to manufacture and use without fire risk, replacing the need for repeated heating cycles associated with plastic shrink wrapping

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

4Strength

If thicker plastic films are used to maintain mechanical properties, then bundling strength is maintained, but manufacturing costs increase

Engineering Contradiction:
Improvefilm mechanical propertiesVSAvoidproduction cost
Core Design Contradiction:
StrengthVSEase of manufacture

Solution Approach 1:

The packaging is segmented into multiple connector flaps that work together to provide the required bundling strength. This segmentation allows the use of thinner, less expensive material while achieving the same overall strength through the combined action of multiple structural elements

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention changes the structural parameters of the packaging from a single thick film to a multi-flap configuration with adhesive bonding, achieving equivalent or superior mechanical properties while using less material and reducing manufacturing costs

Inventive Principle:
Principle #35Parameter changes
