Shower Sliding Door Roller Assembly for Jam-Free Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding doors for shower partitions are complex and time-consuming to install and remove, often jamming during opening or closing due to tilting against runners, requiring increased effort or shaking to move.
Innovation Solution
Height-adjustable rollers with elastic elements and a button mechanism allow for quick engagement and disengagement with runners, enabling secure fixing and easy assembly/disassembly, along with a symmetrical design for improved mobility and wear resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional fixed rollers are used, then the structure is simple, but the installation and removal is complex and time-consuming
Solution Approach 1:
The patent applies the dynamics principle by making the roller height adjustable rather than fixed. The roller can be positioned at different heights along the receiving unit to accommodate variations in runner positioning and door weight distribution. This dynamic adjustment capability enables easy installation and removal while maintaining operational reliability, directly resolving the technical contradiction between installation ease and structural simplicity.
2Reliability
If fixed roller positions are used, then the structure is simple, but the door segment jams due to tilting against runners
Solution Approach 1:
The patent applies parameter changes by allowing the roller height parameter to be adjusted. This enables optimization of the door segment's alignment with the runners, eliminating tilting and jamming issues. The ability to change the roller height parameter ensures smooth door operation and prevents harmful tilting forces, resolving the contradiction between reliability and structural simplicity.
3Manufacturing precision
If non-adjustable rollers are used, then the manufacturing is simple, but the door segment cannot be precisely aligned with runners
Solution Approach 1:
The patent applies dynamics by providing adjustable roller heights that can be precisely positioned. This allows for accurate alignment of the door segment with the runners during installation, ensuring proper operation. The dynamic adjustment capability achieves high manufacturing precision without requiring complex fixed positioning mechanisms, resolving the contradiction between alignment precision and device complexity.
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
Facilitates quick and precise installation/removal, reduces jamming issues by ensuring backlash-free mobility, and allows for easy cleaning and maintenance by pivoting the door segment.
Implementation Method 1
at least one elastic element is assigned to the receiving unit and is designed to largely eliminate the play of movement of the door segment relative to the running rails by generating a prestressing force
Implementation Method 2
the elastic element is designed as a helical spring... the elastic element being arranged between the roller and the receiving unit in such a way that the position of the roller changes relative to the receiving unit as a result of the deformation of the elastic element

AI summary
The door has a door segment (3), at least one upper roller for association with an upper running strip (5) and rotatably mounted on a holding unit (9), at least one lower roller for association with a lower running strip (7) and rotatably mounted on a holding unit (11), whereby the holding units can be joined to the door segment. The upper and lower rollers are height adjustable to provide substantially play-free lateral mobility of the door segment. An independent claim is also included for a shower partition with a sliding door.
