Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If plastic bubble packaging paper is used, then cushioning and protective properties are improved, but environmental pollution and non-degradability worsen

Engineering Contradiction:

Improvecushioning and protective propertiesVSAvoidenvironmental pollution

Core Design Contradiction:

StrengthVSObject-affected harmful factors

Solution Approach 1:

The patent changes the material parameter from plastic to paper, transforming the packaging material into a biodegradable alternative while maintaining the bubble structure for cushioning protection

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite structure combining paper base layer with air-filled bubble packages, achieving both environmental friendliness and effective cushioning performance

Inventive Principle:

Principle #40Composite materials

2Shape

If high-temperature extrusion process is used for bubble film production, then bubble structure formation is improved, but energy consumption and production complexity worsen

Engineering Contradiction:

Improvebubble structure formationVSAvoidenergy consumption

Core Design Contradiction:

ShapeVSUse of energy by moving object

Solution Approach 1:

The patent replaces the thermal extrusion process with a mechanical cold-forming process, using pressure and molding to create bubble structures without high-temperature heating

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent forms bubble structures during the papermaking process itself, creating the cushioning structure in advance rather than through a separate post-processing extrusion step

Inventive Principle:

Principle #10Preliminary action
