Telescopic Column X-ray Detector Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing X-ray imaging apparatuses face stability issues due to long support structures, which compromise the stability of the X-ray detector and result in a large, cumbersome setup that is inconvenient for packing, transportation, and installation.
Innovation Solution
A telescopically engaged column system with raising/lowering mechanisms, including a combination of linear actuators, gas springs, and gear chains, allows for adjustable height and reduced length of support arms, enhancing stability and compactness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the column is made long to match the elevating distance of the X-ray detector, then the height adjustability is improved, but the stability of the detector support deteriorates and the device size increases
Solution Approach 1:
The single long column is segmented into multiple telescopic column sections that can extend and retract independently. This segmentation allows the column to achieve the necessary elevating distance while maintaining structural stability, as each section contributes to the overall length without requiring a single excessively long support structure.
Solution Approach 2:
The telescopic column employs a nested structure where multiple column sections are inserted within each other. The inner columns are nested within outer columns, allowing compact storage when retracted and extended length when needed. This nesting principle enables the column to provide both height adjustability and structural stability without increasing the overall device footprint.
2Object-generated harmful factors
If the arm supporting the X-ray detector is made long to accommodate the shifted X-ray source, then the interference avoidance is improved, but the detector support stability deteriorates
Solution Approach 1:
The arm supporting the X-ray detector is designed as a dynamic structure that can adjust its position and orientation. This dynamic capability allows the arm to maintain optimal support stability while accommodating the shifted X-ray source position, avoiding the need for a permanently long rigid arm that would compromise stability.
3Object-generated harmful factors
If both the column and arm are made long to avoid interference, then the interference avoidance is improved, but the device becomes large-sized and inconvenient for packing and transportation
Solution Approach 1:
Both the telescopic column and the arm are designed as dynamic, adjustable structures. The telescopic column can extend to the necessary length during operation to avoid interference with the X-ray source, then retract to a compact size for transportation and storage. This dynamic capability resolves the contradiction between needing long dimensions for interference avoidance and compact dimensions for portability.
