Sliding Door Damping Mechanism with Central Catch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sliding door assemblies have complex designs and installation procedures due to multiple components and discrete fastening means, which complicate both the design and installation processes.
Innovation Solution
A sliding door assembly with a single catch or stop block at the center of the support track for slowing motion and a mounting arm that attaches to the wall without additional fasteners, simplifying the design and installation by eliminating the need for braking mechanisms at the ends and reducing the number of discrete parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional sliding door assemblies use braking mechanisms at both ends of the support track, then the door motion can be controlled, but the design becomes complicated and requires multiple discrete components
Solution Approach 1:
The patent combines the braking function into a single integrated catch mechanism located at the center of the support track, eliminating the need for separate braking mechanisms at both ends. This merging of functions reduces the number of discrete components while maintaining effective door motion control.
Solution Approach 2:
The single catch mechanism serves multiple functions: it acts as a braking mechanism for both directions of door motion, serves as a stop block to prevent over-travel, and simplifies the overall structure by eliminating the need for end-braking components. This multi-functionality resolves the contradiction between operational control and design complexity.
2Reliability
If conventional sliding door assemblies use discrete fastening means to secure the sliding door to the wall, then the door can be firmly attached, but the installation procedure becomes complicated
Solution Approach 1:
The mounting arm integrates the fastening function directly into the track assembly, combining the attachment mechanism with the support structure. This eliminates the need for separate discrete fasteners and simplifies the installation procedure while maintaining secure attachment to the wall.
Solution Approach 2:
The mounting arm is designed to self-attach to the wall structure without requiring additional fastening components. The integrated design allows the track assembly to secure itself to the wall through the mounting arm's built-in attachment mechanism, reducing installation complexity and time.
3Ease of operation
If conventional sliding door assemblies have braking mechanisms at the ends of the track, then door motion can be controlled, but the door cannot travel the full length of the support track
Solution Approach 1:
The patent extracts the braking function from the ends of the track and relocates it to the center through the single catch mechanism. This extraction allows the door to travel the full length of the support track without being constrained by end-braking mechanisms, while still providing effective motion control through the centrally located catch.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a simplified design and quick installation process, allowing sliding doors to travel the full length of the track without gaps and enabling easy mounting next to each other, while also incorporating a damping mechanism to slow the door's motion effectively.
Implementation Method 1
movement of said object that moves said piston towards said plug member compresses air between said piston and said plug member to absorb the moving object's energy
Implementation Method 2
damping means disposed within said track member actuatable in response to said side to side movement of said door to break said door's movement

AI summary
A sliding door apparatus for opening and closing an opening in a wall. A sliding door apparatus including a longitudinally extending track member mountable along an upper edge of an opening and a door movably mountable on the track member for sliding movement thereon between opened and closed positions. A damping structure is disposed within the track member and is actuatable in response to the sliding movement of the door to break the door's movement as it approaches its opened and closed positions.
