Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing unlocking devices for maintenance track systems in rail vehicles are complex, difficult to handle, and occupy significant space, especially when using a common electric drive for lifting and releasing the track beams.
Innovation Solution
A compact unlocking device with a movable actuating device that simultaneously manipulates the locking element and lifting element in opposite directions, utilizing a rack and pinion gear for efficient locking and unlocking, allowing the track beam to be raised with minimal effort and space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a common electric drive is used for lifting and releasing the track beam, then both functions can be performed with a single drive, but the device occupies a relatively large amount of installation space
Solution Approach 1:
The patent combines the lifting element and locking element into a single integrated unlocking device that is actuated by one common electric drive. The actuating device simultaneously manipulates both elements in opposite directions, merging two functions (lifting and releasing lock) into one compact unit, thereby reducing installation space while maintaining functionality.
Solution Approach 2:
The invention uses a rack and pinion gear mechanism where the actuating device moves in a first actuating direction to manipulate the locking element and in an opposite second actuating direction to manipulate the lifting element. This dimensional approach allows simultaneous operation of both elements in opposite directions from a single drive source, optimizing space utilization.
2Ease of operation
If lifting and releasing the lock are performed separately, then each function can be optimized, but the unlocking device becomes comparatively complex and difficult to handle
Solution Approach 1:
The patent merges the separate operations of lifting and releasing the lock into a single actuating action. The common electric drive simultaneously manipulates both the locking element and lifting element, reducing operational complexity and improving ease of handling while maintaining functional optimization through the rack and pinion mechanism.
3Force
If the track beam is lifted slightly during unlocking, then it can be moved and removed from the support area with as little effort as possible, but the unlocking device requires additional space and complexity
Solution Approach 1:
The lifting element performs a preliminary lifting action on the track beam during the unlocking process. By slightly raising the track beam before removal, the device reduces the effort needed to move and remove the beam from the support area. This preliminary action is integrated into the single actuating mechanism, avoiding additional complexity.
