Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the solar generator module is directly and slantingly fixed to the cylinder, then the structure is simple, but the structural strength is insufficient to withstand strong winds

Engineering Contradiction:
Improvestructure simplicityVSAvoidstructural strength
Core Design Contradiction:
Device complexityVSStrength

Solution Approach 1:

The support structure is segmented into multiple independent components: middle column, first support arm, second support arm, and cable system. This segmentation allows each component to bear specific loads and provides structural flexibility to withstand strong winds while maintaining overall stability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention combines multiple support mechanisms (middle column, support arms, and cable system) into a unified hybrid support structure. This merging of different structural elements creates a composite system that achieves both structural strength for wind resistance and controlled adjustability for tracking.

Inventive Principle:
Principle #5Merging (Combining)

2Stability of the object's composition

If the solar generator module is fixed in a fixed manner, then the structure is stable, but the ability to adjust to the azimuth angle of the sun is limited

Engineering Contradiction:
Improvestructural stabilityVSAvoidsun tracking capability
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The support structure incorporates dynamic elements including the rotatable middle column, adjustable support arms, and cable-controlled positioning mechanism. These dynamic components enable the solar generator module to adjust its orientation to track the sun's azimuth angle while maintaining structural stability through controlled movement.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system enables parameter changes in the solar generator module's orientation and position through the adjustable support arms and cable tensioning mechanism. The middle column's rotation capability and the support arms' angle adjustments allow the module to change its azimuth angle to follow the sun's movement throughout the day.

Inventive Principle:
Principle #35Parameter changes

3Power

If the solar generator module area is increased, then the power generation capacity is improved, but the module may be damaged by strong winds due to insufficient connection strength

Engineering Contradiction:
Improvepower generation capacityVSAvoidwind resistance
Core Design Contradiction:
PowerVSReliability

Solution Approach 1:

The support structure is segmented into multiple independent components: middle column, first support arm, second support arm, and cable system. This segmentation allows each component to bear specific loads and provides structural flexibility to withstand strong winds while maintaining overall stability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cable system acts as a pre-configured cushioning mechanism that provides additional support and load distribution before strong winds arrive. The cables are tensioned in advance to create a protective support network that prevents excessive movement and reduces stress on the connections during high-wind events.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)
