Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional packaging methods are used for dispensing content from refill cartridges, then manufacturing is simpler, but sustainability and material versatility are limited

Engineering Contradiction:
Improvematerial versatilityVSAvoidmanufacturing complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The actuator is constructed using composite materials including biodegradable polymers, flexible membranes, and rigid structural components. This allows the packaging to achieve both sustainability goals and functional versatility while managing manufacturing complexity through integrated design

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The packaging system is divided into separate modular components: a reusable actuator housing and replaceable refill cartridges. This segmentation allows different materials to be optimized for specific functions while simplifying the overall manufacturing process through standardized interfaces

Inventive Principle:
Principle #1Segmentation

2Object-affected harmful factors

If biodegradable and recyclable materials are used, then environmental impact is reduced, but manufacturing precision and structural reliability may be compromised

Engineering Contradiction:
Improveenvironmental impactVSAvoidstructural precision
Core Design Contradiction:
Object-affected harmful factorsVSManufacturing precision

Solution Approach 1:

The design utilizes parameter changes in biodegradable materials through controlled cross-linking density, crystallinity, and additive formulations to achieve the necessary structural precision and reliability while maintaining environmental benefits

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

Composite structures combine biodegradable materials with reinforcing elements and protective coatings to ensure manufacturing precision and structural reliability are maintained despite using environmentally friendly base materials

Inventive Principle:
Principle #40Composite materials

3Adaptability or versatility

If hybrid structures combining semi-rigid, flexible, and composite materials are used, then functionality and sustainability are improved, but device complexity increases

Engineering Contradiction:
Improvefunctional versatilityVSAvoidstructural complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The hybrid structure is segmented into distinct functional zones: semi-rigid components for structural support, flexible membranes for content delivery, and composite elements for connectivity. Each zone is optimized independently, managing overall structural complexity while achieving functional versatility

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The actuator design incorporates multi-functional elements that serve multiple purposes: the same structural component provides both mechanical support and acts as a sealing surface, reducing the need for additional parts and managing structural complexity

Inventive Principle:
Principle #6Universality (Multi-functionality)
