Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex additional connecting component is used to connect the motor to the brush head assembly, then the connection is more stable, but the energy consumption increases and the structure becomes more complicated
Solution Approach 1:
The connection system is divided into distinct functional segments: the motor bracket with motor, the sealing ring, the eccentric shaft, and the actuating shaft. This segmentation allows each component to perform its specific function efficiently, reducing overall energy consumption while maintaining connection stability.
Solution Approach 2:
The eccentric shaft acts as an intermediary component between the motor's driving shaft and the actuating shaft. It mediates the power transmission and enables the brush head assembly to rotate without requiring complex additional connecting components, thereby reducing energy consumption.
2Reliability
If a complex additional connecting component is used to connect the motor to the brush head assembly, then the connection is more stable, but the device complexity increases
Solution Approach 1:
The motor bracket, sealing ring, and shaft components are merged into an integrated connection system. The motor bracket combines motor mounting and sealing functions, while the eccentric shaft integrates power transmission and actuation functions, eliminating the need for separate complex connecting components.
Solution Approach 2:
The eccentric shaft serves multiple functions simultaneously: it transmits power from the motor, provides the eccentric motion needed for brush head rotation, and connects to the actuating shaft. This multi-functionality reduces the number of components needed and simplifies the overall structure.
3Reliability
If the brush head assembly is connected with complex components, then the connection is more secure, but the assembly and disassembly process becomes more difficult
Solution Approach 1:
The connection system incorporates dynamic elements that allow for easy assembly and disassembly. The bayonet mechanism enables quick engagement and disengagement of the brush head assembly, while the sealing ring maintains secure connections during operation. This dynamic design allows the structure to be simple during assembly but secure during use.

AI summary
A brush head component connection system, applied in a personal care utensil, comprises: a brush head component and a motor bracket (11) mounted on a personal care utensil casing (13), a motor (10) disposed in the motor bracket (11), and a seal ring (12) located between the motor bracket (11) and the personal care utensil casing (13). A driving shaft of the motor (10) is disposed in holes at the center of the bottoms of the motor bracket (11), the personal care utensil casing (13) and the seal ring (12), and has an end connected to one end of an eccentric shaft (14). The other end of the eccentric shaft (14) deviates from the central position and is connected to the driving shaft connected onto the brush head component. In the brush head component connection system, the motor (10) is connected to the brush head component only through simple components such as the eccentric shaft (14) and the driving shaft, and the motor (40) drives the eccentric shaft to rotate through rotation of the driving shaft, so as to drive the brush head component to rotate; therefore, the energy consumption is low.
