Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If wave power generation technologies absorb wave energies from one or at least two directions, then the device complexity is reduced, but the adaptability to absorb wave energies from all directions deteriorates
Solution Approach 1:
The swing box is designed to perform multiple functions: it can swing in a first swing direction to drive the swing input shaft, and also swing in a second swing direction (longitudinal rotation) to drive the power output shaft through bevel gears. This multi-functional design allows the device to absorb wave energies from all directions while maintaining reasonable complexity.
2Power
If the swing box rotates longitudinally to the right using a bevel gear, then the power output is achieved, but the rotation power generated by the swing input shaft is canceled out due to reverse rotation, reducing energy absorption efficiency
Solution Approach 1:
The transmission system is segmented into independent pathways: the swing input shaft and swing box form one segment for lateral wave energy absorption, while the bevel gears form another segment for longitudinal wave energy absorption. This segmentation allows each segment to independently convert wave energies without interference, preventing the cancellation of rotation power.
3Ease of operation
If the rotation direction of the swing box is opposite to the output direction of the bevel gear, then the power transmission is achieved, but the stability of the power output deteriorates, resulting in large fluctuation
Solution Approach 1:
The power output shaft acts as an intermediary that receives rotation power from both the swing input shaft (through the swing box) and the bevel gears (through longitudinal rotation). By combining these two power sources on the same output shaft, the system achieves stable power output with reduced fluctuations, as the intermediary integrates and smooths the combined energy inputs.
