Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Linear motor conveying systems face limitations in high-speed transportation due to cogging and limited load capacity, especially in curves, caused by one-sided guidance and magnetic attraction, leading to rapid wheel wear and restricted load positioning.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If one-sided guidance with magnetic attraction is used, then the system can provide guidance and propulsion, but wheel wear increases rapidly and load capacity is limited
Solution Approach 1:
The patent transitions from asymmetric one-sided guidance to symmetric dual-sided guidance. By placing bearing surfaces and electromagnetic motor components on both sides of the carrier module, the system achieves balanced load distribution and eliminates the concentrated wear caused by one-sided magnetic attraction and guidance forces.
Solution Approach 2:
The dual-sided configuration creates counterbalancing forces that offset each other. The electromagnetic attraction and guidance forces on one side are balanced by corresponding forces on the opposite side, preventing excessive localized stress on the wheels and reducing wear.
2Speed
If one-sided magnetic attraction is used for guidance, then the system structure is simpler, but centrifugal force effects limit high-speed curve performance
Solution Approach 1:
The patent employs symmetric dual-sided electromagnetic motor components that provide balanced propulsive forces. During curved motion, this symmetry allows the system to counteract centrifugal forces more effectively, as the opposing sides can generate differential forces to maintain stable trajectory at high speeds.
Solution Approach 2:
The system adds the dimensional aspect of bilateral force application. Instead of unidirectional electromagnetic forces, the dual-sided configuration enables force application from opposite directions, creating a more controllable force vector system that can manage centrifugal effects during curved motion.
3Quantity of substance
If one-sided guidance is used, then the track module structure is simpler, but load capacity and load positioning are restricted
Solution Approach 1:
The patent implements symmetric dual-sided bearing surfaces and electromagnetic motor components on the track module. This symmetry enables the carrier module to support greater loads through distributed contact points and balanced force application, while the modular design keeps structural complexity manageable.
Solution Approach 2:
The dual-sided configuration serves multiple functions simultaneously: it provides guidance, propulsion, and load support through the same structural elements. The bearing surfaces and electromagnetic components on both sides work together to enhance load capacity while maintaining versatile operational capabilities.
