Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional damping devices for rail-guided door elements are often too long, limiting the opening width and requiring significant installation space, making them difficult to install, especially in confined spaces, and complicating the positioning of damping elements.
Innovation Solution
A compact damping device design featuring a receiving body that can be pushed into the guide rail, allowing the carriage to move into it, with a damping element and spring mechanism for precise positioning and braking, enabling flexible installation and adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If conventional piston-cylinder damping elements are mounted in the longitudinal direction of the guide rail, then the damping function is achieved, but the overall length increases and the opening width of the door opening is limited
Solution Approach 1:
The damping element is rotated 90 degrees and mounted transversely to the longitudinal direction of the guide rail. This dimensional change allows the damping function to be achieved while significantly reducing the overall length of the damping device in the longitudinal direction, thereby increasing the opening width of the door opening.
Solution Approach 2:
The damping element is received within a receiving body that is integrated into the carriage structure. This nesting arrangement allows the damping component to be compactly housed within the existing carriage volume, further reducing the overall length and allowing the device to be pushed into the guide rail.
2Area of stationary object
If damping elements are mounted in limited space, then installation space requirements are reduced, but exact positioning becomes extremely difficult
Solution Approach 1:
The receiving body is designed with pre-established positioning features including a positioning surface and a positioning recess that mate together. This preliminary preparation of positioning mechanisms allows the damping device to be easily and accurately positioned when installed in the guide rail, eliminating the difficulty of exact positioning in limited spaces.
Solution Approach 2:
The receiving body acts as an intermediary component between the damping element and the guide rail. It provides a standardized interface with positioning features that simplify the installation process and ensure accurate positioning, while allowing the damping element itself to be compact and suitable for limited installation spaces.
3Length of moving object
If the damping device is made shorter to increase opening width, then the opening width is improved, but the damping element may not have sufficient space to function
Solution Approach 1:
The damping element is nested within the receiving body, which is integrated into the carriage structure. This nesting arrangement efficiently utilizes the available volume within the carriage, providing sufficient space for the damping element to function reliably while keeping the overall length of the damping device short.
Solution Approach 2:
By mounting the damping element transversely rather than longitudinally, the available space within the carriage volume is more effectively utilized. This dimensional change allows the damping element to have sufficient functional space while maintaining a compact overall length of the device.
