Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surfable wave generator systems face issues with the generation of rear waves, which cause splashing, flooding, and increased energy consumption due to the need for complex synchronised mechanisms to compensate for water elevation changes.
Innovation Solution
A tilting generator system with a top axis of rotation and a convex face that minimizes rear wave formation by integrating wave generation and compensation into a single solidary block, eliminating the need for additional synchronised displacers or compensators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple wave generators are deployed to increase wave generation capacity, then wave generation effectiveness is improved, but device complexity and coordination difficulty increase
Solution Approach 1:
The system is divided into multiple independent modular wave generators, each capable of autonomous operation. Each module contains its own power take-off system, hydraulic circuitry, and control capabilities, allowing them to function independently while contributing to collective wave generation effectiveness.
Solution Approach 2:
Each modular wave generator is designed with universal interfaces and standardized components that enable them to perform the same wave generation function while being easily replaceable and scalable. The modules can be deployed in various configurations and locations, providing flexibility in system deployment and maintenance.
2Stability of the object's composition
If fixed wave generators are installed in specific locations, then wave generation stability is improved, but adaptability to different water conditions deteriorates
Solution Approach 1:
The wave generators incorporate adjustable mechanical components including variable pitch propellers, adjustable flap angles, and controllable oscillation frequencies. These dynamic adjustments allow the fixed installations to adapt to varying water depths, currents, and wave conditions while maintaining stable operational characteristics.
Solution Approach 2:
The system enables modification of operational parameters such as oscillation frequency, amplitude, and phase relationships between modules. Power input parameters can be adjusted to match different water conditions, allowing the fixed generators to optimize performance across varying environmental conditions.
3Stability of the object's composition
If wave generators operate continuously to maintain consistent wave patterns, then wave generation consistency is improved, but energy consumption increases
Solution Approach 1:
The wave generation system employs periodic oscillation patterns that can be synchronized across multiple modules. By using periodic action, the system maintains consistent wave patterns through rhythmic, predictable cycles rather than continuous high-energy operation, allowing for energy efficiency while preserving wave consistency.
Solution Approach 2:
The system maintains continuous wave generation capability through modular redundancy and synchronized operation. When all modules operate together, they produce consistent patterns; when some are offline for maintenance or energy conservation, others continue operation to maintain useful wave action without requiring all components to consume maximum energy continuously.
4Ease of manufacture
If traditional propellers or flaps are used for wave generation, then manufacturing simplicity is maintained, but environmental harm to marine life increases
Solution Approach 1:
The system converts potentially harmful high-speed rotating propellers into gentler oscillating motion mechanisms. By using reciprocating flaps and undulating surfaces that move more slowly and predictably, the system eliminates the cavitation and debris ingestion problems of traditional propellers while still effectively generating waves for power extraction.
Solution Approach 2:
The patent replaces traditional rotating propeller mechanics with oscillating flap and undulating surface mechanisms. This substitution changes the fundamental mechanical action from high-speed rotation to controlled reciprocating motion, reducing harmful effects on marine life while maintaining wave generation capability through hydraulic or direct drive systems.
