Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If new perfume raw materials and delivery systems are introduced to expand the pool of available options, then variations in odor profiles and longevity are improved, but the complexity of the perfume formulation system increases

Engineering Contradiction:

Improvevariations in odor profilesVSAvoidperfume formulation system

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the perfume delivery system into multiple independent delivery mechanisms including microcapsules, macrocapsules, and free perfume materials. Each component can be independently formulated and optimized for specific odor profiles and release characteristics, allowing perfumers to mix and match components to achieve desired variations without overwhelming system complexity

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent employs universal delivery system components that can accommodate multiple perfume raw materials with different properties. The microcapsule and macrocapsule structures serve as multi-functional carriers that can deliver various fragrance compounds, enabling a standardized platform that reduces overall system complexity while maintaining versatility in odor profile creation

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Duration of action of moving object

If perfume delivery systems use microcapsules and macrocapsules for controlled release, then longevity of scent is improved, but the manufacturing precision requirements increase

Engineering Contradiction:

Improvescent longevityVSAvoidcapsule formulation

Core Design Contradiction:

Duration of action of moving objectVSManufacturing precision

Solution Approach 1:

The patent utilizes parameter changes in the capsule wall composition, thickness, and cross-linking degree to control perfume release rates and longevity. By adjusting these physical and chemical parameters within defined ranges, the system achieves extended scent duration while maintaining manufacturability through standard encapsulation processes

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent employs composite capsule structures combining different polymer materials with varying degradation rates and permeability characteristics. This composite approach allows tuning of release profiles through material selection rather than precise manufacturing control, reducing manufacturing precision requirements while achieving desired longevity

Inventive Principle:

Principle #40Composite materials

3Measurement precision

If amine-assisted delivery and cyclodextrin complexes are used to enhance perfume retention, then odor detection threshold is improved, but the device complexity increases

Engineering Contradiction:

Improveodor detection thresholdVSAvoiddelivery system

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent introduces amine compounds and cyclodextrin molecules as intermediary substances that facilitate perfume retention and controlled release. These intermediaries form reversible complexes with perfume materials, enhancing odor detection threshold through controlled release mechanisms while adding only minimal complexity through the incorporation of well-established chemical additives

Inventive Principle:

Principle #24Intermediary (Mediator)
