Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If static divert mechanisms with single functionality are used, then device complexity is reduced, but adaptability and versatility deteriorate
Solution Approach 1:
The patent applies multi-functionality by enabling a single divert mechanism to perform multiple functions through programmable control. The divert can be configured to divert objects to different locations, adjust diversion angles, and operate in various modes (timed diversion, continuous diversion, selective diversion) without requiring multiple separate mechanical devices, thus improving adaptability while managing device complexity through software-based control rather than hardware proliferation
2Power
If heavy motorized components are used for divert mechanisms, then power and driving capability are improved, but weight and maintenance requirements worsen
Solution Approach 1:
The patent replaces traditional heavy motorized components with a linear induction motor system that uses electromagnetic fields to drive the divert mechanism. This substitution reduces mechanical weight while maintaining or improving driving capability through non-contact electromagnetic actuation, thereby reducing the weight of moving components and associated maintenance requirements while preserving the necessary power for effective object diversion
3Ease of operation
If static divert mechanisms are used, then ease of manufacture is improved, but ease of operation and system flexibility deteriorate
Solution Approach 1:
The patent applies dynamics by transitioning from static divert mechanisms to a dynamically controllable system. The divert mechanism can be programmed to operate in real-time based on object characteristics, timing requirements, and desired diversion parameters. This dynamic operation allows the system to adapt to varying operational conditions without requiring complex manufacturing, as the flexibility is achieved through software control rather than complex mechanical design
4Reliability
If frequent maintenance is required, then reliability deteriorates, but device complexity and component quantity worsen
Solution Approach 1:
The patent applies self-service by designing the linear induction motor-driven divert mechanism to minimize maintenance requirements through non-contact electromagnetic actuation and reduced mechanical wear. The system maintains higher reliability by avoiding the frequent maintenance needs of traditional motorized components, achieving this through a cleaner, more robust design that reduces the complexity of maintenance operations rather than increasing device complexity to enable easier maintenance

Implementation Method 1
By applying current to a stator in a defined polarization or direction and/or at a particular frequency, the spherical rotors may rotate about a specific axis and at a particular angular velocity

AI summary
Linear induction motor-driven divert mechanisms may be installed or associated with conveying systems and may cause a change in velocity of one or more objects (i.e., a change in direction and/or a change in speed) to passing through the conveying systems. The divert mechanisms may include one or more spherical rotors including magnetizable slugs, and the spherical rotors may be rotatably positioned above positioned above one or more stator plates. Energizing one or more of the stator plates causes the corresponding spherical rotors to rotate in a given direction. Therefore, the divert mechanism may be used to transport or direct objects within conveying systems by controlling the rotation and angular velocity of one or more of the spherical rotors, which may impart motion to the objects.
