Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complete motor product is placed in the electronic device, then the motor function is achieved, but the space usage increases and manufacturing complexity increases
Solution Approach 1:
The motor is merged with the electronic device structure by integrating the stator with the circuit board and the rotor with the housing. The base serves as both a structural component and a motor component, eliminating the need for separate motor housing and mounting structures. This merging reduces the overall space required while maintaining complete motor functionality.
2Reliability
If a complete motor product is independently designed and manufactured, then the motor performance is optimized, but the production cost increases due to repeated resource use
Solution Approach 1:
The manufacturing processes for the motor components are merged with the existing electronic device manufacturing processes. The stator is formed as part of the circuit board manufacturing process, and the rotor is integrated with the housing manufacturing. This eliminates the need for separate motor manufacturing steps and reduces production costs through resource consolidation.
Solution Approach 2:
The base serves multiple functions: it provides structural support for the electronic device, serves as the motor housing, provides mounting surfaces for the stator and rotor, and acts as part of the motor assembly. This multi-functionality reduces the number of separate components needed and simplifies the manufacturing process.
3Reliability
If the motor is mounted on the circuit board through a bearing base, then the motor is securely fixed, but the device thickness increases
Solution Approach 1:
The bearing base is merged with the circuit board structure, eliminating the need for separate mounting brackets or extended housing. The stator is directly mounted on the circuit board plane, and the rotor is positioned within the same thickness envelope as the electronic components, minimizing the overall device thickness while maintaining secure fixation.
