Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple independent floating bodies are used to increase energy absorption, then energy conversion efficiency improves, but structural reliability deteriorates due to high wave forces causing failures
Solution Approach 1:
The patent combines multiple floating bodies (first and second floating bodies) into a single integrated wave generator structure. This merging allows the system to absorb wave energy from multiple directions simultaneously while sharing structural loads, thereby improving both energy absorption capability and structural reliability compared to independent floating bodies
Solution Approach 2:
The wave generator is segmented into distinct functional components (first floating body, second floating body, shaft, generator) that can independently respond to wave forces while being structurally integrated. This segmentation allows each component to be optimized for its specific function while maintaining overall structural integrity
2Productivity
If traditional wave generators are used in low wave intensity environments, then energy generation is insufficient, but system complexity increases to improve sensitivity
Solution Approach 1:
The patent merges the floating bodies and shaft into an integrated structure where the shaft serves dual purposes: as a structural support and as the rotational element for energy generation. This reduces the need for additional complex components while maintaining sensitivity to low wave intensity
Solution Approach 2:
The shaft performs multiple functions: it connects the floating bodies, serves as a rotational axis for the generator, and provides structural support. This multi-functionality reduces system complexity while maintaining effective energy generation in low wave intensity environments
