Foldable Wardrobe Door Drive With Adjustable Movement Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drive and guide systems for foldable doors in wardrobes and furniture are difficult to adapt to varying dimensions and do not effectively control the movement of closing doors throughout their range.
Innovation Solution
A drive device with a sliding guide and guide slider system, including a rotatable drive member connected to biasing means, such as helical springs, and damping devices, which allows for adjustable and controlled movement of foldable doors, adaptable to different sizes and configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If known guide and drive systems are used for foldable doors, then the door movement can be driven, but the systems are difficult to adapt to different wardrobe configurations and dimensions
Solution Approach 1:
The patent employs a telescopic rod with adjustable length that can be extended or retracted to accommodate different door configurations and wardrobe dimensions. The rod's length can be dynamically adjusted during installation to match specific requirements, providing adaptability without requiring completely different system designs for various applications.
Solution Approach 2:
The invention allows modification of key parameters including the telescopic rod length, magnetic means positioning, and biasing spring characteristics to adapt the system to different wardrobe sizes and door weights. By changing these parameters rather than the overall system architecture, the patent achieves versatility while maintaining relatively simple device structure.
2Reliability
If telescopic rod with magnetic means is used to drive door movement, then the door can be attracted towards closing or opening position, but effective control of movement throughout the entire range is not achieved
Solution Approach 1:
The patent combines multiple control mechanisms into a single integrated drive device: the telescopic rod provides the mechanical linkage, magnetic means provide attraction force, and biasing springs provide continuous pressure. This merging of functions allows reliable control throughout the entire door movement range without requiring separate control systems for different movement phases.
Solution Approach 2:
The biasing spring acts as an intermediary element that continuously presses the telescopic rod against the door, ensuring maintained contact and control throughout the movement range. This intermediary mechanism bridges the gap between the magnetic attraction force and the mechanical movement, providing reliable control from closing to opening position and vice versa.
