Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If water-soluble materials are used for pouches, then environmental sustainability and convenience are improved, but structural integrity and handling durability deteriorate

Engineering Contradiction:
Improveenvironmental sustainabilityVSAvoidstructural integrity
Core Design Contradiction:
Object-affected harmful factorsVSStrength

Solution Approach 1:

The patent uses composite materials by combining water-soluble polymers (PVA, PVOH) with water-soluble plastics to create a pouch material that maintains structural integrity while being environmentally sustainable. This composite approach allows the pouch to have both the desired strength for handling and the solubility for environmental benefit.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent applies parameter changes by controlling the molecular weight, degree of hydrolysis, and crystallinity of the water-soluble polymers used. By adjusting these parameters, the pouch achieves optimal balance between structural strength and water solubility, allowing it to maintain integrity during handling but dissolve effectively when exposed to water.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If water-soluble pouches are designed to dissolve quickly, then convenience and environmental friendliness are improved, but structural stability during storage and handling deteriorates

Engineering Contradiction:
Improvedissolution speedVSAvoidstructural stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The patent controls the dissolution speed while maintaining structural stability by adjusting parameters such as the degree of crystallinity and molecular weight of the water-soluble polymers. Higher crystallinity and molecular weight provide structural stability during storage, while still allowing controlled dissolution when exposed to water.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent applies dynamics by designing the pouch to exhibit different properties under different conditions: it maintains structural stability under dry storage and handling conditions, but transitions to rapid dissolution when exposed to water. This dynamic behavior allows the pouch to satisfy both contradictory requirements.

Inventive Principle:
Principle #15Dynamics

3Loss of substance

If traditional packaging materials are replaced with water-soluble alternatives, then plastic waste is reduced, but production cost increases

Engineering Contradiction:
Improveplastic waste reductionVSAvoidproduction cost
Core Design Contradiction:
Loss of substanceVSEase of manufacture

Solution Approach 1:

The patent applies the principle of disposable objects by using water-soluble materials that can be produced at lower costs compared to traditional plastics. The pouch is designed as a single-use item that dissolves after use, eliminating the need for expensive recycling infrastructure and reducing long-term waste management costs.

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

Solution Approach 2:

The patent implements discarding and recovering by allowing the pouch to naturally dissolve in water, recovering the materials in a harmless form that can return to the environment. This eliminates the need for energy-intensive recycling processes and reduces overall production and disposal costs.

Inventive Principle:
Principle #34Discarding and recovering

4Ease of operation

If water-soluble materials are used in food products, then portion control and convenience are improved, but compatibility with food products (especially those containing moisture or fats) deteriorates

Engineering Contradiction:
Improveportion controlVSAvoidcompatibility with food products
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent uses composite materials by combining multiple water-soluble polymers (PVA, PVOH, and water-soluble plastics) to create a pouch that is compatible with various food products. This composite structure provides resistance to premature degradation from moisture and fats while maintaining the desired water solubility for dissolution.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent applies parameter changes by adjusting the hydrophobicity and chemical composition of the water-soluble materials to improve compatibility with food products. By modifying these parameters, the pouch resists premature degradation from contact with moisture and fats in food, while still dissolving effectively when intended.

Inventive Principle:
Principle #35Parameter changes
