Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a general air-cooled structure is adopted for high-power motors, then the cooling system is simple in structure, but dust adheres to the surface after long-term use, seriously affecting the heat dissipation performance
Solution Approach 1:
The patent transitions from air cooling to liquid cooling by introducing a cooling water circulation system with cooling water inlets and outlets on the motor housing. Liquid cooling provides superior heat dissipation capacity and is less susceptible to dust accumulation effects, thereby resolving the contradiction between structural simplicity and heat dissipation performance reliability.
2Reliability
If cooling water is used to cool the driving motor box, then the cooling capacity is sufficient, but the cooling water cannot allocate heat dissipation capacity based on the working conditions of each motor, resulting in waste of heat dissipation capacity
Solution Approach 1:
The patent divides the cooling system into multiple independent cooling channels, each corresponding to a specific motor. The cooling water inlet is divided into multiple inlet channels that can independently control cooling water flow to different motors. This segmentation enables differential cooling allocation based on individual motor working conditions, preventing waste of cooling capacity while maintaining sufficient overall cooling capability.
Solution Approach 2:
The patent introduces dynamically adjustable cooling control through independently controllable cooling water inlet channels for each motor. This allows the cooling system to adaptively adjust the cooling water flow rate to each motor based on its real-time working conditions, transforming the static cooling system into a dynamic one that optimizes heat dissipation capacity allocation and avoids energy waste.
3Power
If multiple shunt power generators are used in the main wind power gearbox, then the power generation capacity is increased, but there is no connection between the various shunt power generators, resulting in insufficient overall stability
Solution Approach 1:
The patent merges multiple shunt power generators into an integrated assembly structure where the generators are collectively mounted on a common base plate with unified fastening and positioning features. This merging approach maintains the individual power generation capacity of each generator while providing overall structural stability through the integrated assembly design, resolving the contradiction between power generation capacity and system stability.
