Three-Sided Folding Door Apparatus With Dynamic Pulley System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional folding doors are limited in their ability to change direction of protrusion or folding state based on environmental conditions, requiring reconstruction when space use purposes change, and cannot maintain a horizontal state during movement.
Innovation Solution
A three-sided folding apparatus with rotating pulleys and turning members allows for equal interval movement of upper and lower components, maintaining a horizontal state and enabling adjustable folding angles, thus improving manufacturability and reducing material costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the folding door is configured to be completely folded and accommodated only toward the indoor or outdoor side, then the structure is simple, but it cannot change the direction of accommodation/protruding when the use purpose changes
Solution Approach 1:
The patent applies dynamics by making the folding apparatus movable and adjustable rather than fixed. The turning member allows the folding door to dynamically change its accommodation direction between indoor and outdoor sides, and the moving means enable adjustment of protruding length according to different usage scenarios
Solution Approach 2:
The folding apparatus is designed with multi-functionality to accommodate both indoor and outdoor directions, and to adjust protruding lengths according to different needs. This universal design allows the same apparatus to serve multiple purposes without requiring reconstruction
2Stability of the object's composition
If the folding door uses conventional moving means, then the structure is simple, but it cannot maintain a horizontal state when the folding door is moved
Solution Approach 1:
The patent employs counterweight principles through the coordinated action of multiple moving means (first upper, first lower, second upper, second lower) that balance each other to maintain horizontal movement. The pulley systems create counterbalancing forces that prevent tilting during the folding operation
Solution Approach 2:
The pulleys serve as intermediary elements that mediate between the moving means and the folding door. These intermediaries transmit and distribute forces evenly, ensuring the door maintains a horizontal state during movement by coordinating the action of multiple moving components
3Adaptability or versatility
If the folding door requires reconstruction to change accommodation direction, then the current structure can be simple, but it lacks flexibility for changing space use purposes
Solution Approach 1:
The folding apparatus is designed with dynamic adjustability through the turning member and moving means, allowing it to adapt to different accommodation directions and protruding lengths without requiring reconstruction. This dynamic design provides flexibility for changing space use purposes while maintaining manufacturing simplicity

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enhances the stability and usability of folding doors by allowing them to maintain a horizontal state and adjust folding angles, preventing leaning or tilting, and simplifying the structure for improved manufacturability and cost-effectiveness.
Implementation Method 1
a first end of a first wire is coupled to the second side of the second upper moving means, and a second end thereof is coupled to the first side of the second lower moving means through the first rotating pulley via the sixth rotating pulley and through the fifth rotating pulley
