Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two different motors and two sets of transmission mechanisms are used to drive grinding and powder pressing functions, then the functionality is complete, but the overall size and manufacturing cost increase
Solution Approach 1:
The patent combines two separate transmission mechanisms into one integrated transmission mechanism. The first transmission shaft connects to both the grinding component and the powder pressing component through a shared transmission path, allowing both functions to be driven by a single motor while reducing the overall size of the device.
Solution Approach 2:
The single transmission mechanism is designed to serve multiple functions simultaneously. The first transmission shaft can drive the grinding component for coffee bean grinding, and through the second transmission shaft, also drive the powder pressing component for compacting the ground coffee powder, making the transmission system universal for both operations.
2Adaptability or versatility
If two different motors and two sets of transmission mechanisms are used, then both grinding and powder pressing functions are achieved, but the manufacturing cost increases
Solution Approach 1:
The patent merges two separate motor and transmission systems into one integrated system. By using a single motor to drive a shared transmission mechanism that controls both grinding and powder pressing functions, the number of parts is reduced, assembly complexity is lowered, and manufacturing cost is decreased while maintaining complete functionality.
Solution Approach 2:
The transmission mechanism is designed as a universal system that can perform both grinding and powder pressing operations. This multi-functional design eliminates the need for separate dedicated systems for each function, thereby reducing manufacturing costs through economies of scale and simplified production processes.
3Volume of stationary object
If a single driver and shared transmission mechanism are used, then the volume and manufacturing cost are reduced, but the complexity of synchronized operation must be managed
Solution Approach 1:
The transmission mechanism is segmented into distinct functional modules: a first transmission shaft for grinding operation, a second transmission shaft for powder pressing operation, and a connecting mechanism that coordinates between them. This segmentation allows each module to be optimized independently while maintaining overall synchronization, reducing the perceived complexity of the integrated system.
Solution Approach 2:
The patent introduces a connecting mechanism that acts as an intermediary between the first and second transmission shafts. This intermediary component coordinates the rotation and power transmission between the two shafts, ensuring synchronized operation of the grinding and powder pressing functions while simplifying the overall control architecture.
