Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If large wave energy systems are used to translate a large portion of total wave energy, then energy capture efficiency is improved, but the system becomes more susceptible to damage from water or wind currents, storms or other inclement weather

Engineering Contradiction:
Improveenergy capture efficiencyVSAvoidsusceptibility to damage from weather
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system divides the wave energy conversion function into multiple small independent floaters (first floater, second floater, etc.) rather than using a single large system. Each floater is equipped with its own lever arm and can operate independently, allowing the system to capture wave energy effectively while reducing the vulnerability of any single component to weather damage.

Inventive Principle:
Principle #1Segmentation

2Reliability

If small wave energy devices are used to reduce susceptibility to damage and maintain minimal offshore presence, then reliability and aesthetic appeal are improved, but energy capture efficiency decreases

Engineering Contradiction:
Improvesusceptibility to damage from weatherVSAvoidenergy capture efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent combines multiple small floaters into a coordinated system where each floater has its own lever arm mechanism. By merging the functionality of multiple small units while maintaining their individual resilience, the system achieves both the reliability of small devices and improved overall energy capture through collective operation.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The lever arms are designed to be rotatable and adaptable, allowing each floater to dynamically adjust its configuration based on wave conditions. This dynamic capability enables small floaters to maximize their energy capture potential while maintaining the reliability advantages of smaller individual components.

Inventive Principle:
Principle #15Dynamics

3Device complexity

If fixed lever arm length is used to simplify system design, then device complexity is reduced, but adaptability to varying wave parameters decreases

Engineering Contradiction:
Improvesystem design complexityVSAvoidadaptability to wave parameters
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The lever arms are designed with rotatable joints that allow them to change their effective length and orientation in response to varying wave parameters. This dynamic adjustability enables the system to adapt to different wave conditions without requiring complex active control mechanisms, achieving adaptability through passive mechanical design.

Inventive Principle:
Principle #15Dynamics
