Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single engine is used to drive multiple propellers, then the device complexity is reduced, but the power distribution efficiency deteriorates
Solution Approach 1:
The power transmission system is segmented into multiple independent transmission paths through the use of a power distribution device with separate input and output shafts. Each output shaft can independently transmit power to different propellers, enabling efficient power distribution while maintaining a single engine configuration.
Solution Approach 2:
A power distribution device acts as an intermediary between the single engine and multiple propellers. This intermediate mechanism receives power from the engine's output shaft and distributes it to multiple output shafts, each driving a separate propeller, thereby solving the power distribution efficiency problem.
2Force
If multiple propellers are disposed to get bigger thrust, then the thrust increases, but the device complexity worsens
Solution Approach 1:
The power distribution device serves multiple functions simultaneously: it receives power from a single engine, distributes power to multiple propellers, and enables independent control of each propeller. This multi-functionality allows the system to achieve big thrust with multiple propellers while keeping the overall device complexity manageable.
Solution Approach 2:
The transmission system extends in multiple spatial dimensions with input and output shafts arranged at different angles and positions. This dimensional arrangement allows multiple propellers to be positioned optimally for thrust generation while sharing a common power source through the power distribution device.
3Adaptability or versatility
If power is transmitted to multiple loads in different directions, then the versatility improves, but the transmission system complexity worsens
Solution Approach 1:
The power distribution device incorporates dynamic elements such as bevel gears and shafts that can transmit power in multiple directions. The transmission paths are designed to adapt to different spatial requirements, allowing power to be directed to multiple loads in different orientations while maintaining a relatively simple overall structure.

AI summary
A power transmission system includes a power source, a first power transmission distribution device, a first load and a second load. A power outputted by the power source is transmitted to the first power transmission distribution device, is divided into a first transmission power and a second transmission power through the first power transmission distribution device, and is transmitted to the first load and the second load, respectively. The transmission direction for the power to be inputted to a first power input end is perpendicular to the transmission direction of the first transmission power and the second transmission power, and the transmission direction of the first transmission power is opposite to the transmission direction of the second transmission power.
