Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If spur gear transmissions are used to transform motor rotary motion to fin rotary motion, then the driving mechanism can achieve torque multiplication, but the torque impacts on gears become bigger and the structure becomes more complex requiring intermediate transmission shafts
Solution Approach 1:
The patent combines the motor, gear transmissions (spur gears and bevel gears), and fin assembly into a single integrated driving mechanism unit. This merging eliminates the need for separate intermediate transmission shafts and reduces structural complexity while maintaining torque multiplication capability through the combined gear system.
Solution Approach 2:
The patent employs a nested arrangement where the first spur gear pair and second spur gear pair are integrated within the same transmission housing, with the bevel gear pair nested at the output end. This nesting approach compactly arranges multiple gear stages without requiring additional intermediate shafts, reducing overall structural complexity.
2Ease of manufacture
If a modular design is used for easy disassembly and integration, then the ease of manufacture and maintenance is improved, but the device complexity increases due to multiple modular components
Solution Approach 1:
The patent divides the driving mechanism into distinct modular segments: the motor module, the gear transmission module (with spur and bevel gears), and the fin assembly module. Each module can be manufactured, tested, and assembled independently, improving ease of manufacture and maintenance while the standardized interfaces between modules minimize the overall complexity increase.
