Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If separate devices are used for water injection after perforating, then water injection can be performed, but production cost increases and efficiency decreases

Engineering Contradiction:

Improveproduction costVSAvoidefficiency

Core Design Contradiction:

Ease of manufactureVSProductivity

Solution Approach 1:

The patent combines the water injection function and oxygenation function into a single integrated device that performs both operations simultaneously through shared needle heads. This eliminates the need for separate water injection equipment, reduces production costs, and improves efficiency by performing multiple operations in one step rather than sequentially

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The needle heads are designed with multi-functionality, serving both for oxygen delivery and water injection through the same component. This universal design allows the device to perform perforating, oxygenation, and water injection functions without requiring separate specialized components for each function

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of operation

If manual water injection is performed after perforating, then water can be supplied to mushroom sticks, but labor intensity increases

Engineering Contradiction:

Improvelabor intensityVSAvoidefficiency

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The device enables automated water injection through the integrated needle heads that automatically deliver water to the mushroom sticks during the same operation cycle as oxygenation. This self-service mechanism eliminates the need for manual water injection operations, reducing labor intensity while maintaining or improving efficiency

Inventive Principle:

Principle #25Self-service

3Productivity

If integrated apparatus is used for perforating, oxygenating and water injection, then work efficiency improves and production cost reduces, but device complexity increases

Engineering Contradiction:

Improvework efficiencyVSAvoiddevice complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent merges multiple functions (perforating, oxygenating, water injection) into a single integrated apparatus with shared components, particularly the needle heads that serve multiple purposes. This consolidation reduces the overall number of separate devices needed, and while the individual device becomes more multifunctional, the total system complexity is reduced compared to having separate devices for each function

Inventive Principle:

Principle #5Merging (Combining)
