Telescopic Lifting Unit Segmented Drive for Compact X-Ray Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional telescopic lifting units for mobile equipment, such as X-ray machines, are structurally complex and require significant space, obstructing the user's view and requiring substantial power for movement, especially when handling heavy loads.
Innovation Solution
A telescopic lifting unit comprising a first segment, a second segment, and a third segment, where the first and second segments are displaced by a motor unit for rapid movement and the second and third segments are displaced by a cable hoist for a space-saving and precise adjustment, combining the advantages of motor-driven and cable-driven systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a motor-driven drive train is used to move the telescopic lifting unit, then the speed of movement is improved, but the space required and structural complexity increase
Solution Approach 1:
The drive system is segmented into two distinct parts: a motor unit for the first and second segments providing rapid movement, and a cable hoist for the second and third segments providing space-saving operation. This segmentation allows each subsystem to be optimized for its specific function, achieving high speed where needed while minimizing space and complexity in other areas.
2Speed
If a motor-driven drive train is used to move the telescopic lifting unit, then the speed of movement is improved, but the space required increases
Solution Approach 1:
The drive system is divided into a motor unit serving the first and second segments, and a cable hoist serving the second and third segments. This segmentation enables the motor unit to provide rapid movement capability while the cable hoist provides a compact, space-efficient solution for the upper segments, thereby achieving high speed performance without proportionally increasing the overall space required.
Solution Approach 2:
The cable hoist mechanism utilizes a different spatial arrangement compared to a conventional motor-driven telescopic column. By employing cables and pulleys, the system achieves vertical segment movement with a more compact footprint, effectively trading mechanical directness for spatial efficiency.
3Reliability
If conventional telescopic lifting columns are used in mobile equipment, then the lifting function is achieved, but the user's view is obstructed when moving the equipment
Solution Approach 1:
The lifting column is divided into three segments with two different drive mechanisms. The cable hoist portion (second and third segments) can be operated to reduce the visible profile of the column when not in use, while the motor unit (first and second segments) provides rapid deployment capability. This segmented design with dual drive systems enables both reliable lifting function and reduced view obstruction during equipment movement.

Function Achieved in This Case
Enables compact configuration, reduced effort for movement, and precise height adjustment, preventing obstruction during use while efficiently handling loads, with the motor unit providing quick coarse adjustments and the cable hoist offering fine adjustments.
Implementation Method 1
The motor unit interacts with a spindle to convert a rotational movement of the motor of the motor unit into a translational movement between the first and second segments
Implementation Method 2
a cable hoist configured to move said second and third segments relative to one another
