Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding shower door systems experience impacts during opening and closing due to inertia, and existing solutions like flexible closers are aesthetically unpleasing as their components are exposed, affecting user experience.
Innovation Solution
An impact-free gently positioned door opening and closing structure featuring a rail assembly with pulley and flexible closer assemblies, where the flexible closer and pulleys are hidden within the rail, using positioning elements to control the door's speed and position, ensuring smooth operation without external exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If flexible closers are mounted on rails with actuators exposed to the outside, then the impact problem is solved to a certain extent, but the appearance of the shower room is negatively affected
Solution Approach 1:
The flexible closer actuator is nested within the rail structure. The rail is designed with a hollow interior space that accommodates the actuator, allowing the damping function to be integrated into the rail itself rather than being mounted externally. This nesting approach eliminates exposed components while maintaining the impact reduction function.
Solution Approach 2:
The flexible closer system is merged with the rail structure by integrating the actuator into the rail's hollow interior. The mounting bracket connects the actuator to the rail from the interior side, combining the damping mechanism and support structure into a unified assembly that maintains a clean external appearance.
2Ease of operation
If additional touching blocks are disposed on the movable door piece to actuate the flexible closers, then the door positioning is improved, but the device complexity increases
Solution Approach 1:
The touching block function is extracted from the movable door piece and transferred to the rail structure. The positioning element with its positioning protrusion is integrated into the rail, eliminating the need for separate touching blocks on the door piece. This extraction simplifies the overall system by reducing the number of components.
Solution Approach 2:
The rail structure is given multiple functions: it provides structural support for the sliding mechanism, contains the hollow interior for housing the actuator, and incorporates positioning elements with protrusions that actuate the flexible closer. This multi-functionality reduces the need for separate dedicated components.
