Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If magnets of different shapes and dimensions are used for each power transmission apparatus specification, then the magnetic coupling can meet various specification requirements, but the manufacturing cost increases and magnets cannot be shared between different couplings
Solution Approach 1:
The patent applies universality by designing magnets with a standardized shape and size that can be used across multiple magnetic coupling applications. The key innovation is using magnets of identical dimensions (e.g., 10mm×10mm×2mm) for both the inner rotor and outer rotor, allowing the same magnet design to serve multiple functions and specifications. This standardized magnet design enables sharing between different coupling specifications, reducing manufacturing costs while maintaining adaptability through configurable arrangements.
Solution Approach 2:
The patent applies segmentation by dividing the magnetic coupling system into modular components with standardized magnets that can be independently configured. The magnets are segmented into identical units that can be arranged in different patterns (e.g., alternating polarity arrangements) to meet various specification requirements. This segmentation allows flexible configuration using the same basic magnet unit, achieving versatility without requiring custom magnets for each specification.
2Adaptability or versatility
If magnets of different shapes are used for each specification, then the magnetic coupling can be customized for specific applications, but it becomes difficult to share magnets between magnetic couplings
Solution Approach 1:
The patent eliminates device complexity by using a universal magnet design with standardized shape and dimensions that can be applied across all magnetic coupling specifications. The same magnet geometry (e.g., rectangular prism with dimensions 10mm×10mm×2mm) serves multiple purposes in different coupling configurations. This universality reduces the variety of magnet types needed while maintaining the ability to customize couplings through different magnet arrangements and quantities.
Solution Approach 2:
The patent achieves customization without increasing device complexity by changing the arrangement parameters and quantity of identical magnets rather than changing magnet shapes. Specifications are adjusted by modifying parameters such as the number of magnets, their spatial distribution, and polarity patterns, while the fundamental magnet geometry remains constant. This approach maintains adaptability while minimizing the variety of magnet designs required.
3Manufacturing precision
If magnets are manufactured according to each coupling specification, then the magnetic coupling can meet precise specification requirements, but the manufacturing process becomes more complex and costly
Solution Approach 1:
The patent resolves the manufacturing contradiction by creating a universal magnet specification that can be produced using a single manufacturing process and tooling setup. The standardized magnet dimensions (e.g., 10mm×10mm×2mm) allow for consistent manufacturing precision across all coupling applications without requiring retooling or process adjustments. This universality maintains specification compliance while significantly simplifying the manufacturing process and reducing costs.
