Sliding Door Stopper System with Bumper
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sliding door systems for shower and tub enclosures face the risk of derailment due to rapid opening or excessive force, which can result in injury and damage, especially when the doors are made of glass or are heavy and fragile, as they lack effective stopping mechanisms to prevent such incidents.
Innovation Solution
A stopper system comprising a striker member attached to the sliding door and a stopper member attached to the rail or rod, featuring engagement and disengagement mechanisms to prevent horizontal and vertical movement, with a bumper to absorb impact and prevent derailment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a stopper is installed to stop rapid opening or excessive force, then the door can be stopped effectively, but the door may derail due to impact and jump from the track
Solution Approach 1:
A bumper is installed on the stopper member to provide cushioning before the door impact. The bumper absorbs impact energy and reduces the force transmitted to the door, preventing derailment while maintaining effective stopping capability
Solution Approach 2:
The bumper acts as an intermediary element between the door and the stopper. It mediates the impact force, converting the direct hard impact into a cushioned stopping action that prevents the door from jumping or derailing
2Shape
If the enclosing frame is eliminated for aesthetic benefits, then the appearance is improved, but the risk of derailment increases
Solution Approach 1:
The stopper system with bumper serves as an intermediary safety mechanism that compensates for the eliminated enclosing frame. It provides the necessary containment and protection against derailment while allowing the aesthetic benefits of an open frame design
3Shape
If glass doors are used for aesthetic and modern design, then the appearance is improved, but the risk of injury and damage increases due to fragility
Solution Approach 1:
The bumper provides beforehand cushioning for glass doors, absorbing impact energy before it can transmit to the fragile glass. This prevents the door from derailing or shattering, reducing injury and damage risk while maintaining the aesthetic benefits of glass doors
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 system effectively stops the sliding door without causing damage and prevents derailment, ensuring safety by limiting the door's motion and absorbing impact forces, thus preventing potential injuries and damage.
Implementation Method 1
at least one bumper proximate one of said at least two ends; to absorb the force of said sliding door when said striker member makes contact with said stopper member
