Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual assembly techniques are used for pressing and aligning modules with outer casings, then operational flexibility is maintained, but alignment accuracy and press force uniformity deteriorate due to large manual alignment errors

Engineering Contradiction:

Improveoperational flexibilityVSAvoidalignment accuracy

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

The patent replaces manual mechanical alignment and pressing operations with an automated positioning and pressing device that uses mechanical structures (positioning plates, pressing assemblies) to achieve precise alignment and uniform press force, eliminating manual alignment errors while maintaining operational control

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the operational parameters from manual control to automated control with fixed positioning parameters, where the positioning plate and pressing assembly use predetermined geometric parameters and forces to achieve consistent alignment accuracy and press force uniformity across different assembly operations

Inventive Principle:

Principle #35Parameter changes

2Device complexity

If manual assembly techniques are used for pressing and aligning modules with outer casings, then device complexity is reduced, but press force uniformity deteriorates due to uneven manual pressure application

Engineering Contradiction:

Improveassembly process simplicityVSAvoidpress force uniformity

Core Design Contradiction:

Device complexityVSStability of the object's composition

Solution Approach 1:

The patent replaces manual pressing operations with an automated pressing assembly that uses mechanical structures (pressing plates, positioning mechanisms) to apply uniform press force, eliminating the variability of manual pressure application while maintaining a relatively simple device structure

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent segments the pressing function into distinct modular components (positioning plate, pressing assembly, support structures) that can be independently designed and adjusted, allowing for uniform force distribution while keeping the overall device structure organized and manageable

Inventive Principle:

Principle #1Segmentation

3Manufacturing precision

If automated positioning and pressing devices are implemented, then alignment accuracy and press force uniformity are improved, but device complexity increases

Engineering Contradiction:

Improvealignment accuracyVSAvoidstructure complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent designs the positioning plate and pressing assembly to perform multiple functions (positioning, alignment, pressing, and maintaining pressure) within a single integrated structure, reducing the need for separate components and thereby limiting the increase in device complexity while achieving improved alignment accuracy and press force uniformity

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Productivity

If automated positioning and pressing devices are implemented, then assembly yield rate is improved, but production cost increases

Engineering Contradiction:

Improveassembly yield rateVSAvoidproduction cost

Core Design Contradiction:

ProductivityVSEase of manufacture

Solution Approach 1:

The patent designs a multi-functional automated positioning and pressing device that can handle different assembly operations with a single apparatus, reducing the need for multiple specialized devices and thereby limiting the increase in production cost while improving assembly yield rate through automated precise alignment and pressing

Inventive Principle:

Principle #6Universality (Multi-functionality)
