Solution Overview
Problem
Existing insertion devices for generating synchrotron radiation face challenges in maintaining precise gap control due to deformation of coupling beams caused by attractive forces between magnet arrays, leading to suboptimal magnetic-field intensity distribution.
Innovation Solution
The design incorporates a compensation spring mechanism with an auxiliary frame system that allows for optimal placement of the compensation spring mechanism, decoupling its operation from the gap driving mechanism and enabling relative movement to minimize beam deformation, using a spring conjunction mechanism with guide and auxiliary frames to manage moments induced by the compensation springs.

Engineering Contradiction Analysis
1Reliability
If a compensation spring mechanism is coupled to coupling beams via coupling portions placed between coupling shafts, then the compensation spring mechanism can counteract attractive forces between magnet arrays, but the positions of coupling portions are inevitably determined by coupling shaft positions, preventing optimal placement for minimizing beam deformation
Solution Approach 1:
The patent divides the coupling structure into separate functional components: coupling shafts for transmitting driving forces and auxiliary frames for mounting compensation spring mechanisms. This segmentation allows each component to be optimized independently, with coupling shafts positioned for mechanical coupling and auxiliary frames positioned to minimize beam deformation while providing mounting locations for the compensation springs.
Solution Approach 2:
The patent introduces auxiliary frames as intermediary structures between the coupling beams and the compensation spring mechanisms. These auxiliary frames serve as mediators that decouple the positioning constraints of the coupling shafts from the optimal positioning requirements of the compensation springs, allowing the springs to be placed at locations that best minimize beam deformation.
2Device complexity
If coupling portions are placed between coupling shafts to avoid physical interference, then the structure remains compact, but the compensation spring mechanisms cannot be placed at optimal positions for minimizing coupling beam deformation
Solution Approach 1:
The patent resolves the spatial conflict by transitioning from a one-dimensional arrangement (placing components along the beam length) to a multi-dimensional configuration using auxiliary frames that extend perpendicular to the coupling beam. This allows compensation spring mechanisms to be mounted on auxiliary frames at positions that optimize deformation minimization without interfering with coupling shafts, effectively utilizing three-dimensional space.
3Ease of operation
If the magnet supporting members are coupled to coupling beams via coupling shafts, then the gap driving mechanism can change the gap size, but the attractive forces between magnet arrays cause deformation of the coupling beams
Solution Approach 1:
The patent implements preliminary anti-action by introducing compensation spring mechanisms that pre-counteract the attractive forces between magnet arrays before these forces can cause significant beam deformation. The compensation springs are positioned and pre-loaded to oppose the magnetic attraction, thereby maintaining the coupling beams in a more stable position and preserving the intended magnetic-field intensity distribution.
Solution Approach 2:
The patent employs parameter changes by adjusting the stiffness, pre-load, and positioning of compensation spring mechanisms to optimize their counteracting effect. By carefully selecting spring parameters and their mounting positions on auxiliary frames, the system achieves optimal compensation for beam deformation while maintaining gap driving functionality.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration effectively minimizes deformation of coupling beams, maintains precise gap control, and ensures consistent magnetic-field intensity distribution, enhancing the generation of synchrotron radiation with desired properties.
Implementation Method 1
a compensation spring mechanism adapted to act in a direction in which an attractive force acting between the first magnet array and the second magnet array is cancelled
Implementation Method 2
a guide mechanism for guiding relative movement of the first spring supporting frame and the second spring supporting frame, in the direction in which the magnet arrays are facing each other
Implementation Method 3
If an electron beam having been accelerated to near the light velocity in a vacuum is bent within a magnet field, radiated light is emitted in tangential directions of the trajectory of the movement of the electron beam. This is called synchrotron radiation.
Implementation Method 4
a first magnet array including a plurality of magnets placed in an array; a second magnet array including a plurality of magnets placed in an array
