Solution Overview
Problem
Existing sliding door systems for building walls face challenges in achieving rapid opening and closing while minimizing excessive forces, ensuring durability and cost-effectiveness, maintaining aesthetic appeal, and facilitating easy maintenance.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a sliding door system is designed to open and close quickly for safety and practical reasons, then the speed of door operation is improved, but the forces generated become excessive which affects durability and cost-effectiveness
Solution Approach 1:
The patent applies parameter changes by optimizing the movement trajectory of the door leaves through a specifically designed link component with a curved guide. This guide transforms the linear displacement movement into a rotational pivoting movement with optimized kinematics, allowing rapid door operation while controlling the forces generated during the process. The guide's geometric parameters are designed to regulate acceleration and force distribution throughout the door's movement cycle.
2Shape
If the mechanism of the sliding door is hidden from outside for aesthetic reasons, then the aesthetic appearance is improved, but accessibility for repair and maintenance becomes difficult
Solution Approach 1:
The patent applies segmentation by dividing the door system into distinct modular components: door leaves, a door leaf support, a linear guide device, and a coupling device with link component. This modular segmentation allows the mechanism to be concealed within the wall structure for aesthetic purposes while enabling easy access to individual components for maintenance. The link component and control lever can be independently accessed and serviced without affecting the entire door system.
3Ease of operation
If a coupling device with link component and control lever is used to convert displacement into rotational movement, then the coordination of door leaf pivoting is improved, but the device complexity increases
Solution Approach 1:
The patent applies the intermediary principle by introducing a link component with a curved guide as a mediator between the linear guide device and the pivoting mechanism. This link component with its specifically shaped guide profile serves as an intermediary that converts the linear displacement movement into the required rotational pivoting movement of the door leaves. The control lever acts as another intermediary element that couples this conversion process to the pivoting mechanism, achieving coordinated door leaf movement through a clear functional chain.
