Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sliding type linkage shower rooms face issues such as unsmooth sliding due to pulley assembly rust, high frame height obstructing access for elders and children, cumbersome installation, and inability to be installed from the front, making them inconvenient and difficult to use, especially for online shoppers.
Innovation Solution
A sliding rail low-obstacle linkage shower room with a C-shaped upper rail, a low-profile sliding block unit, and a linkage movement mechanism using gear racks and eccentric adjusting structures, allowing for modular installation and adjustment without a positioning structure, reducing noise and facilitating easy movement and installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a pulley assembly is used for sliding movement, then the shower room can achieve low-obstacle or obstacle-free movement, but the pulley assembly easily rots and rusts with water leading to unsmooth sliding
Solution Approach 1:
The patent removes the pulley assembly entirely from the system and replaces it with a sliding rail mechanism. The shower glass slides directly along the rail without any pulleys, eliminating the component that was prone to rust and rotation issues while maintaining the low-obstacle sliding capability.
Solution Approach 2:
The patent replaces the pulley-based mechanical system with a direct rail-guided sliding system. This substitution eliminates the need for rotating components and bearings that are susceptible to water damage, providing a more reliable and maintenance-free sliding mechanism.
2Stability of the object's composition
If a fixed block is provided on the lower rail to prevent glass shaking, then the glass stability improves, but the frame body height must be at least 50 mm which obstructs access for elders and children
Solution Approach 1:
The patent moves the stability mechanism from the horizontal plane (fixed block on lower rail) to the vertical plane (upper rail with positioning structure). The positioning structure engages with the upper part of the shower glass, providing stability without requiring a tall lower frame body, thus maintaining low obstacle height for easy access.
Solution Approach 2:
The patent introduces an upper rail as an intermediary element that provides both the positioning structure for glass stability and a guide for smooth sliding. This upper rail acts as a mediator that simultaneously addresses stability requirements while keeping the lower frame body low for accessibility.
3Stability of the object's composition
If at least two lower rails are provided in the current linkage shower room, then the glass stability improves, but the width across the lower rails becomes even wider making it more inconvenient for users to cross over
Solution Approach 1:
The patent merges the functions of multiple lower rails into a single integrated upper rail system. This single rail provides both stability through its positioning structure and guidance for sliding, while minimizing the width obstruction for users. The consolidation of multiple rails into one reduces the overall width occupied by the rail system.
4Stability of the object's composition
If the shower room is installed from the side with fixed frame bodies, then the structural stability improves, but the adjustment and repair become cumbersome requiring door removal and disassembly
Solution Approach 1:
The patent segments the shower room into modular components: fixed frame bodies that remain installed and movable components (shower glass, sliding mechanism) that can be independently adjusted and replaced. This segmentation allows the frame bodies to stay fixed for structural stability while enabling easy adjustment and repair of the sliding mechanism without removing the entire door assembly.
Solution Approach 2:
The patent creates a dynamic system where the shower glass and sliding mechanism can be independently adjusted along the fixed frame bodies. The adjustable positioning structures allow for easy modification of the sliding glass position and overlap, enabling repairs and adjustments without disassembling the fixed frame bodies or removing the door.
5Strength
If a double-side upper rail and front baffle are provided, then the structural integrity improves, but the shower room cannot be installed from the front and cannot be modularly assembled
Solution Approach 1:
The patent uses asymmetric design in the upper rail structure, with the C-shaped cross-section providing structural integrity on one side while being open on the other side for installation access. This asymmetric configuration allows the rail to maintain strength while enabling front-side installation and modular assembly, breaking the symmetry that would require installation from both sides.
Solution Approach 2:
The patent inverts the traditional installation approach by designing the upper rail to be installed from the front rather than from the sides. The C-shaped open structure allows the rail to be placed into position from the front, reversing the conventional installation sequence and enabling modular assembly without requiring access from both sides of the shower room.

AI summary
A sliding rail low-obstacle linkage shower room include an upper rail and a lower rail, a fixed glass, a primary shower glass and a secondary shower glass. The lower rail is correspondingly fixed on a bottom of the secondary shower glass. A sliding block unit is installed on the lower rail. The sliding block unit includes a fixed portion, a sliding groove and a guidance sliding portion. The fixed portion is fixed on the bottom of the secondary shower glass. A bottom of the primary shower glass is inserted into the sliding groove to form a linkage. The guidance sliding portion is glidingly engaged with the lower rail. The linkage shower room has a simple structure which can be easily manufactured.
