Furniture Door Guide Deflection for Preventing Transition Collisions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing guide systems for hingedly connected door leaves in furniture can cause jamming and mechanical stress due to premature pivoting during transition between guide rails, leading to collisions with the furniture body or other door leaves.
Innovation Solution
Incorporation of deflection elements in the transition area between guide rails to prevent premature pivoting of door leaves, allowing them to be fully extended before pivoting relative to the furniture side wall, using rotatable rollers with adjustable positioning to ensure smooth movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If door leaves are moved from retracted position to extended position manually, then door leaves can be opened for access, but door leaves may tilt too early in transition area causing jamming
Solution Approach 1:
A deflection element is introduced as an intermediary component between the door leaf and the furniture body side wall. This deflection element prevents direct contact and premature pivoting by acting as a mediator that guides the door leaf through the transition area smoothly, eliminating the jamming problem while maintaining ease of operation.
2Adaptability or versatility
If door leaves are allowed to pivot freely in transition area, then movement is flexible, but collisions with side wall cause mechanical stress and jamming
Solution Approach 1:
The deflection element is positioned in advance in the transition area to prevent premature pivoting and collisions before they can occur. By applying preliminary anti-action through the deflection element, the system prevents harmful collisions with the side wall while maintaining the flexibility needed for door leaf operation.
3Device complexity
If deflection element is fixed in position, then structure is simple, but cannot accommodate variations in door leaf movement
Solution Approach 1:
The deflection element is designed to be movable rather than fixed, allowing it to adapt dynamically to variations in door leaf movement. This mobility enables the deflection element to maintain optimal positioning throughout the transition area while keeping the overall structure relatively simple, balancing complexity with adaptability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Prevents collisions and jamming by ensuring door leaves are fully extended before pivoting, reducing mechanical stress and maintaining smooth operation.
Implementation Method 1
at least two deflection elements are provided for supporting the door leaves at least in a transition region between the first and second guide, wherein the deflection elements prevent a collision between the furniture body, in particular the side wall of the furniture body, and/or a panel arranged thereon and at least one door leaf in the transition region
Implementation Method 2
at least one of the deflection elements can be mounted so that it can move, preferably rotate. The deflection element can be rotationally symmetrical, for example, as a rotatable roller.
