Railway Apparatus Securing Mechanism with Guided Slides
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing railway apparatus securing devices require manual access for attachment, lack sufficient clamping force, and are complex to motorize and construct, making them unsafe and difficult to handle and transport.
Innovation Solution
A securing device with a guiding slide and upper and lower beams connected by a movable connecting member, allowing movement in two independent directions, and a self-locking drive mechanism with a chain and sprocket system for easy adjustment and secure attachment, enabling precise height adjustment and safe handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a simple flange-based securing mechanism is used, then the device is easy to manufacture and operate, but manual access to the loading platform is required for tightening, creating safety risks and complicating handling procedures
Solution Approach 1:
The patent introduces an intermediary mechanism (the securing device with movable attachment member) that mediates between the operator and the railway apparatus. The attachment member can be positioned and secured without direct manual access to the platform, eliminating the need for personnel to manually tighten flanges on the loading platform while maintaining secure attachment of the railway apparatus
2Ease of operation
If attachment bars with hooks are used to secure railway apparatus, then access to the platform is not required, but the clamping force is insufficient and the system is difficult to motorize
Solution Approach 1:
The patent employs a dynamic attachment member that can move along the guiding slide in response to applied forces. The attachment member is capable of moving between engaged and disengaged positions, allowing the system to adapt to different railway apparatus configurations while maintaining sufficient clamping force through the guided movement mechanism rather than fixed hook positions
Solution Approach 2:
The patent replaces the simple mechanical hook-and-bar system with a more sophisticated guided movement system. The attachment member moving along a guiding slide provides a more robust mechanical linkage that can be easily motorized, substituting the manual lever operation with automated control while maintaining or improving clamping effectiveness
3Ease of operation
If bevelled shims with locking cavities are used to break down movement into components, then safe handling is achieved, but the construction becomes complex
Solution Approach 1:
The patent segments the movement control into two independent components: longitudinal movement along the guiding slide and vertical movement perpendicular to the slide. This segmentation is achieved through the connecting member geometry and guiding slide configuration, allowing safe handling through controlled component movement without requiring complex bevelled shim and locking cavity constructions

AI summary
A device for securing a railway apparatus, comprising a support platform and a mechanism for securing the apparatus on the platform, the securing mechanism comprising:—at least one guiding slide extending in a longitudinal direction, supported by the support platform; and—a member for attaching the apparatus to the platform capable of moving along the guiding slide. The securing mechanism also comprises an upper beam supporting the guiding slide and a lower beam, connected by means of a connecting member so as to be movable in a direction perpendicular to the longitudinal direction of the guiding slide. Moreover, the securing mechanism comprises locking mechanism configured to prevent the movement of the upper beam with respect to the lower beam in said perpendicular direction.
