Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If centralized track planning is used for long transport routes, then comprehensive control of transport units is achieved, but computing power requirements and system complexity increase significantly
Solution Approach 1:
The transport route is divided into multiple transport sections, with each section having its own control unit that independently plans track sections. This segmentation distributes the computational load from a centralized system to multiple decentralized units, reducing overall system complexity while maintaining comprehensive control through coordinated section planning.
2Reliability
If centralized track planning is used for long transport routes, then comprehensive control of transport units is achieved, but computing power requirements increase
Solution Approach 1:
The centralized planning function is segmented into distributed section control units, each handling only the track section within its own transport section. This divides the large computational task into smaller, manageable sub-tasks, significantly reducing the computing power required at any single location while maintaining overall control comprehensiveness.
Solution Approach 2:
Each section control unit performs partial planning action only for its own transport section rather than planning the entire route. This partial action approach reduces computational requirements by focusing resources on local track section planning while relying on coordination with adjacent sections for complete route management.
3Length of stationary object
If transport routes are extended in conventional systems, then longer transport capacity is achieved, but system complexity and cost increase
Solution Approach 1:
The transport route is divided into multiple standardized transport sections that can be independently configured and controlled. When extending the transport route length, additional sections are simply added to the existing modular structure, maintaining consistent control architecture and avoiding proportional increases in overall system complexity.
Solution Approach 2:
Each section control unit is designed with universal functionality to handle track section planning for its own transport section. This multi-functional design allows the same control unit architecture to serve any transport section regardless of position or length, enabling route extension without requiring specialized complex control systems for different sections.
4Reliability
If master-slave control architecture is used for section coordination, then track planning between sections is achieved, but control complexity and communication overhead increase
Solution Approach 1:
Instead of using a hierarchical master-slave architecture where one section controls others, the invention inverts the relationship by giving each section control unit equal status and independent track section planning capability. This peer-to-peer approach reduces control architecture complexity by eliminating master-slave hierarchies while maintaining coordination through standardized inter-section communication protocols.

AI summary
In an electromagnetic transport system, a transport route is divided into transport sections, each including at least one transport segment. A section control unit is assigned to each transport section, and a segment controller is assigned to each transport segment. A logistics unit, specifies a destination of the transport units to section control units via the logistics network. Section control units are connected to segment controllers of associated transport segments via a segment network and are designed to: determine a track section for the associated transport section from the destination, determine target values using the track section and transmit the target values to the segment controllers via the segment network. Segment controllers supply current to drive coils using target values and occurring actual values to generate a magnetic field which interacts with drive magnets of the transport units to move the transport units.
