Insertion Device Spring Conjunction Mechanism for Gap Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insertion devices for synchrotron radiation face challenges in precise gap control due to moments induced by compensation spring mechanisms, leading to deformation and degradation of magnetic-field intensity distribution, and increased device size.
Innovation Solution
The insertion device incorporates a spring conjunction mechanism with a guide mechanism to absorb moments from compensation springs, preventing their influence on gap driving mechanisms, and is designed to maintain stability and reduce size, featuring coupling beams and spring supporting frames that move relative to each other to cancel attractive forces between magnet arrays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If compensation spring mechanisms are used to support magnet arrays, then the magnetic-field intensity distribution is stabilized, but moments induced by the springs cause deformation of gap driving mechanisms and degradation of precise gap control
Solution Approach 1:
A rigid connection structure is introduced as an intermediary between the compensation spring mechanism and the gap driving mechanism. This structure includes a connection beam that rigidly connects the spring supporting frame to the gap driving mechanism, and a connection portion that rigidly connects the beam to the magnet supporting member. This intermediary structure transfers and stabilizes the compensating forces from the springs while preventing the moments from deforming the gap driving mechanism, thus resolving the contradiction between stabilizing magnetic-field distribution and maintaining precise gap control.
2Stability of the object's composition
If compensation spring mechanisms are added to support magnet arrays, then deformation of magnet supporting members is suppressed, but device size increases
Solution Approach 1:
The connection structure is merged with the existing magnet supporting member and gap driving mechanism. The connection beam is integrated into the supporting structure, and the connection portions are combined with existing mounting interfaces. This merging approach allows the compensation spring mechanism to be incorporated without significantly increasing the overall device volume, as the new components share space with existing structural elements.
3Manufacturing precision
If rigid connection structures are used to couple gap driving mechanism and magnet supporting members, then precise gap driving is maintained, but loads from magnet arrays are not effectively compensated
Solution Approach 1:
The connection structure is segmented into distinct functional components: a connection beam that handles force transmission, connection portions that handle moment compensation, and a rigid coupling that maintains precision. This segmentation allows each component to be optimized for its specific function - the beam provides structural rigidity for precision gap driving while the connection portions accommodate the compensating forces from the spring mechanism, thus resolving the contradiction between maintaining precision and achieving effective load compensation.
