One-Piece CT Slip-Ring Support Frame for Vibration Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing CT imaging system support frames suffer from poor rigidity, deformation, and increased weight due to split fan-shaped structures, leading to vibrations and stability issues during high-speed rotation, affecting imaging quality and overall apparatus stability.
Innovation Solution
A unified, integrally formed support frame with a connection flat plate, support body, X-ray source installation, electrical, and cooling component installations, along with a through hole, enhancing rigidity and reducing weight by 30Kg and processing time by 30% through casting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a split fan-shaped box structure is used for the support frame, then the ease of manufacture is improved, but the rigidity and strength deteriorate
Solution Approach 1:
The patent merges the split fan-shaped box structure into a unified integrally formed support frame. The upper and lower pieces are combined into a single cast aluminum alloy structure, eliminating the need for separate components and connections. This merging approach directly resolves the contradiction by providing both ease of manufacture (single-piece casting) and high rigidity/strength (integral structure without joints).
2Productivity
If the rotating speed is accelerated to increase inspection pass rate, then the productivity is improved, but the vibration increases
Solution Approach 1:
The patent employs a fan-shaped (curved/arc) support frame structure that naturally distributes rotational forces more evenly compared to straight-line configurations. The curved geometry of the fan-shaped design helps balance the distribution of the X-ray source, detector, and other components, reducing vibration during high-speed rotation while maintaining high productivity.
Solution Approach 2:
By integrating all support frame components into a single unified structure, the patent eliminates vibration caused by loose connections or relative movements between separate parts. The integral construction ensures that all components move as one rigid unit during rotation, minimizing harmful vibrations even at accelerated speeds.
