Worm-Driven Spare Assembly for Hoist-Free X-Ray Suspension Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In suspended X-ray imaging systems, the failure of driving assemblies in the suspension apparatus results in the apparatus stopping movement, requiring time-consuming and labor-intensive repairs due to the need for hoisting mechanisms to replace heavy components like the telescopic cylinder and tube assembly, disrupting image capture operations.
Innovation Solution
A spare assembly with a worm wheel and worm portion is mounted on the driving assembly, allowing engagement and operation to drive the rotating shaft when the primary assembly fails, enabling the telescopic cylinder and other components to be moved without a hoisting mechanism, facilitating maintenance and allowing partial image capture during repairs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the primary driving assembly fails, then the suspension apparatus stops moving and requires repair, but the repair process requires hoisting mechanisms and takes a long time due to heavy components
Solution Approach 1:
The patent pre-installs a spare driving assembly with a worm wheel and worm portion on the suspension apparatus, positioned to automatically engage when the primary assembly fails. This preliminary preparation eliminates the need for time-consuming hoisting operations during repair, as the spare assembly is already in place and ready for immediate operation.
Solution Approach 2:
The spare driving assembly acts as a backup mechanism that prevents complete operational failure. When the primary assembly fails, the spare assembly engages to maintain suspension movement capability, cushioning against the harmful effect of total mobility loss and enabling continued image capture operations.
2Ease of repair
If the primary driving assembly fails, then components need to be removed and replaced, but the heavy components require hoisting mechanisms that increase device complexity
Solution Approach 1:
The spare driving assembly is pre-mounted on the suspension apparatus in a ready position, eliminating the need for complex hoisting mechanisms during replacement. The spare assembly can be directly engaged with the primary assembly's rotating shaft without requiring external hoisting equipment.
Solution Approach 2:
The worm wheel and worm portion serve as intermediary coupling elements that transfer motion from the spare assembly's rotating shaft to the primary assembly's components. This intermediary mechanism enables smooth transfer of motion without requiring direct manual handling or complex hoisting operations for heavy components.
3Reliability
If the suspension apparatus stops moving for repair, then image capture cannot be performed, but the apparatus needs to remain stationary for safety
Solution Approach 1:
The spare driving assembly is pre-positioned and pre-configured on the suspension apparatus, enabling immediate restoration of movement capability after any failure. This preliminary preparation ensures that the apparatus can quickly resume operation while maintaining safety, as the spare assembly is designed to engage smoothly with the primary assembly's rotating shaft.
Solution Approach 2:
The spare driving assembly acts as a safety net that prevents complete operational failure. When the primary assembly fails, the spare assembly engages to maintain suspension movement capability, cushioning against the harmful effect of total mobility loss and enabling continued image capture operations while maintaining safety.
