Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional wave power generation device is used, then it can convert wave energy into electrical energy, but it cannot stably produce power due to irregular horizontal and vertical motions caused by irregular waves
Solution Approach 1:
The patent employs a pendulum mechanism that dynamically adapts to irregular wave motions. The pendulum's natural frequency and motion characteristics allow it to respond to varying wave conditions, converting irregular horizontal and vertical motions into stable rotational motion that drives the generator consistently regardless of wave irregularity
Solution Approach 2:
The system changes the parameter of motion conversion by transforming irregular multi-directional wave motions into uniform rotational motion through the pendulum mechanism. This parameter transformation enables stable electrical power generation by decoupling the output stability from the input irregularity
2Productivity
If a conventional wave power generation device is used, then it can be结构简单 (simple structure), but it cannot efficiently convert wave energy due to irregular motions
Solution Approach 1:
The pendulum mechanism introduces dynamic motion transformation that efficiently converts irregular wave energy into usable rotational energy. This dynamic component, while adding some structural elements, significantly improves energy conversion efficiency by capturing both horizontal and vertical wave motions and transforming them into consistent rotational drive
Solution Approach 2:
The pendulum mechanism serves multiple functions: it acts as both a motion transformer and an energy converter, handling both horizontal and vertical wave components. This multi-functionality improves overall energy conversion efficiency without requiring separate systems for different wave motion types
