Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a blocking structure is arranged on the side beam to provide braking force, then the magnet track braking device can be blocked, but a torque is easy to be produced and the strength requirement for the blocking structure is relatively high
Solution Approach 1:
The patent combines the blocking structure and positioning structure into a single integrated limiting seat that is fixed to the cross beam. This merging of functions reduces the number of separate components and simplifies the overall structure while maintaining the necessary braking force and positioning capabilities.
Solution Approach 2:
The limiting seat serves multiple functions simultaneously: it provides the blocking function for braking force transmission, the positioning function to limit movement in the height direction, and the support function for the magnet track braking device. This multi-functionality reduces structural complexity and eliminates the need for separate blocking and positioning structures.
2Stability of the object's composition
If a positioning structure is arranged to limit the movement of the magnet track braking device in the height direction, then the magnet track braking device can be prevented from shifting, but the overall structure is relatively complicated

Function Achieved in This Case
The integrated limiting seats simplify the overall structure, reduce stress complexity, and lower costs while maintaining the necessary strength and braking performance.
Implementation Method 1
suction is generated between the magnet track braking device and the rail surface
Implementation Method 2
When there is a relative movement between the magnet track braking device and the rail surface, the friction is generated between the two, and the friction is transmitted from the limiting seat to the cross beam of the framework
