Bottom-Rolling Shower Door Assembly for Water Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding shower door assemblies often rely on header assemblies to bear the weight of the door, which can lead to water leakage and aesthetic issues, as the load is not effectively borne by the bottom portion.
Innovation Solution
A bottom rolling sliding shower door assembly where the vertical load of the door panel is borne by rollers mounted on an axle, with a track positioned beneath the rollers, allowing the door to move along the track and featuring a top guide for stabilization and a roller height adjustment mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the load of the sliding door is borne by a header assembly, then the door can be supported and moved, but water leakage occurs and aesthetics are compromised
Solution Approach 1:
The patent inverts the conventional header-bearing design by transferring the load-bearing function to the bottom track and rollers instead of the top header assembly. This inversion eliminates the header assembly that causes water leakage while maintaining door support and movement functionality through the bottom-mounted roller system.
Solution Approach 2:
The patent extracts and removes the header assembly from the sliding door system, eliminating the source of water leakage. The load-bearing function is extracted from the top and relocated to the bottom track and roller assembly, allowing the door to function without the problematic header component.
2Strength
If the load of the sliding door is borne by a header assembly, then the door can be supported, but the aesthetic appearance is degraded
Solution Approach 1:
The patent inverts the conventional design by moving the visible support mechanism from the top header to the bottom track area. This inversion hides the support structure in the less visible bottom region, improving aesthetics while maintaining the door's load-bearing capability through the bottom-mounted rollers and track system.
3Reliability
If the load of the sliding door is borne by the bottom portion, then aesthetics are improved and water leakage is reduced, but the door stability may be compromised
Solution Approach 1:
The patent introduces a stabilization assembly as an intermediary component that works in conjunction with the bottom load-bearing system. This stabilization assembly, which may include top guides or side rollers, provides the necessary door stability and prevents excessive movement while allowing the bottom rollers to bear the primary load, thus maintaining both aesthetics and structural integrity.
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
This design effectively retains water within the shower enclosure by distributing the door's weight to the bottom rollers, reducing leakage and enhancing aesthetics by eliminating the need for a header assembly, while allowing for easy alignment and movement of the door panel.
Implementation Method 1
The roller assembly includes at least one roller mounted on an axle and at least one roller clamping plate receiving the axle. The vertical load of the door panel is substantially borne by the at least one roller.
Implementation Method 2
The roller may be movable along the track, and the door panel is movable by moving the roller along the track.
