Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If outlets are adjusted using continuous rotation or bending mechanisms, then distance adjustment flexibility is improved, but device complexity and cost increase

Engineering Contradiction:
Improvedistance adjustment flexibilityVSAvoidadjustment mechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The outlet device allows dynamic adjustment of the distance between outlets through movable outlet tubes that can be positioned at different locations along guide paths. The outlets can be moved from an initial position to a final position, providing adaptability while maintaining a relatively simple structural design through the use of guide links and coupling mechanisms.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The adjustment mechanism is segmented into discrete components: outlet tubes, guide links, coupling mechanisms, and holding positions. This segmentation allows for independent adjustment of each outlet while maintaining overall system simplicity, resolving the contradiction between flexibility and complexity.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If outlets are adjusted using continuous rotation mechanisms, then distance adjustment range is improved, but reliability and robustness deteriorate

Engineering Contradiction:
Improvedistance adjustment rangeVSAvoidmechanism robustness
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The system provides dynamic adjustability within a defined range through movable outlet tubes guided by guide links. The outlets can be repositioned along predetermined paths without requiring continuous rotation mechanisms, thereby maintaining reliability while achieving adjustment flexibility within practical limits.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Guide links and coupling mechanisms act as intermediaries between the movable outlet tubes and the fixed mounting structure. These intermediary components transmit motion and force reliably, ensuring robust operation while enabling the desired adjustment range.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Device complexity

If outlets are rigidly coupled via common guide link, then structural simplicity is improved, but adjustment precision and positioning accuracy deteriorate

Engineering Contradiction:
Improvestructural simplicityVSAvoidoutlet positioning accuracy
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The coupling mechanism is segmented into discrete guide links that can be independently positioned at specific holding locations. This segmentation allows for precise positioning of outlets at defined distances while maintaining a relatively simple overall structure, resolving the contradiction between structural simplicity and positioning accuracy.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The guide links and coupling mechanisms enable dynamic repositioning of outlets between defined holding positions. This dynamic capability allows for precise adjustment to specific distances while maintaining structural simplicity through the use of predetermined guide paths and discrete positioning points.

Inventive Principle:
Principle #15Dynamics

4Reliability

If spring force is applied to hold gripper means in position, then positioning stability is improved, but device complexity increases

Engineering Contradiction:
Improvepositioning stabilityVSAvoidpositioning mechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Spring means are used to apply a counteracting force that holds the guide links and coupling mechanisms in their desired positions. The spring force compensates for gravitational and operational forces, ensuring stable positioning without requiring complex locking or actuating mechanisms, thereby resolving the contradiction between positioning stability and device complexity.

Inventive Principle:
Principle #8Anti-weight (Counterweight)
