Engineering Contradiction Analysis
1Power
If a movable object type wave power generation system is used to generate electric energy from wave motion, then energy generation capability is improved, but energy conversion stability deteriorates due to irregular kinetic energy from waves
Solution Approach 1:
The hydraulic motor stores kinetic energy from wave motion in advance by pressurizing hydraulic fluid in an accumulator before power generation is needed. This preliminary energy storage smooths out the irregularities of wave-driven kinetic energy, providing stable hydraulic pressure for consistent power generation output.
Solution Approach 2:
The patent introduces hydraulic fluid as an intermediary medium between the wave-driven movable object and the power generation system. The hydraulic motor converts irregular mechanical motion into stable hydraulic pressure, which then drives the power generation mechanism, decoupling the instability of wave motion from the power generation process.
2Device complexity
If kinetic energy from wave motion is directly converted to electrical energy, then system complexity is reduced, but energy conversion efficiency deteriorates due to irregular motion
Solution Approach 1:
The patent employs a hydraulic motor to convert the irregular mechanical motion from wave-driven tension transmission members into stable hydraulic pressure. This hydraulic intermediary system efficiently captures kinetic energy during wave motion and delivers it consistently to the power generation unit, significantly improving energy conversion efficiency despite adding hydraulic components.
3Adaptability or versatility
If tension transmission members are allowed to move freely with wave motion, then adaptability to wave characteristics is improved, but energy capture consistency deteriorates
Solution Approach 1:
The hydraulic motor provides feedback stabilization by maintaining consistent hydraulic pressure output regardless of variations in wave-driven input motion. The hydraulic system naturally regulates pressure and flow, ensuring consistent energy capture from the tension transmission members while accommodating the full range of wave motion characteristics.
