Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If a single supporting member is used to support the drive member and driven member, then the device complexity is reduced, but the positioning accuracy and alignment between the drive member and driven member deteriorates

Engineering Contradiction:
Improvepositioning accuracy of drive member and driven memberVSAvoidstructure complexity of supporting apparatus
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The supporting apparatus is divided into a first supporting member and a second supporting member, each independently supporting the drive member and driven member respectively. This segmentation allows precise positioning of each member while maintaining overall structural simplicity through modular design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The first and second supporting members are configured with corresponding shapes and structures, allowing them to perform similar supporting functions simultaneously. This universality enables standardized manufacturing while achieving precise alignment through their coordinated arrangement.

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

2Productivity

If the drive member and driven member are not accurately aligned, then the device complexity is reduced, but the linear movement precision and bending operation efficiency deteriorates

Engineering Contradiction:
Improveefficiency of linear movement and bending operationsVSAvoidalignment precision of drive member and driven member
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

By separating the support functions into two distinct supporting members with corresponding structures, the system ensures accurate alignment between drive and driven members during linear movement and bending operations, thereby improving operational efficiency.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The supporting members act as intermediaries that precisely position the drive member and driven member relative to each other, ensuring accurate alignment without requiring complex direct coupling mechanisms.

Inventive Principle:
Principle #24Intermediary (Mediator)
