Furniture Pull-Out Guide Rail With Pivoted Catch Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing guide devices for furniture pull-outs, such as drawers, face challenges in maintaining functional effectiveness when the position of the movable furniture part is adjusted, particularly with respect to side, depth, or height adjustments, as the convergent path of components can lead to inefficiencies in the operation of functional devices like damping and retraction mechanisms.
Innovation Solution
The guide device incorporates a hinge-based bearing mechanism for pivotable suspension of the movement section relative to the base section, ensuring that functional devices remain effective during adjustments, with a catching device and guide surface facilitating the engagement of functional elements to maintain proper guidance and damping functionality, even during lateral or inclination adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If functional devices are fixed on the furniture pull-out with rigid components, then the structure is simple and easy to manufacture, but the functional effectiveness is lost when the position of the movable furniture part is adjusted
Solution Approach 1:
The patent applies the dynamics principle by making the movement section pivotably suspended relative to the base section through bearing means. This allows the functional elements to dynamically adjust their position and maintain proper engagement during lateral or inclination adjustments of the furniture pull-out, resolving the contradiction between functional effectiveness and structural simplicity.
2Adaptability or versatility
If the movable furniture part is adjusted in position (side, depth, height), then adaptability is improved, but the convergent path of components causes functional devices to become ineffective
Solution Approach 1:
The movement section is designed to pivot relative to the base section, enabling it to dynamically adapt to different positions of the furniture pull-out while maintaining functional engagement between components, thus preserving functional effectiveness during position adjustments.
Solution Approach 2:
The patent employs parameter changes by allowing the movement section to change its angular position through pivoting on the bearing means. This parameter change enables the functional elements to maintain proper alignment and engagement despite changes in the overall position of the movable furniture part.
3Ease of manufacture
If fixed components are used for functional devices, then manufacturing precision requirements are reduced, but the guiding surfaces fail to maintain proper contact during adjustments
Solution Approach 1:
The pivotable connection allows the guiding surfaces to dynamically maintain contact during adjustments, reducing the need for extremely precise fixed positioning while ensuring continuous functional engagement between components.
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
This solution ensures that the functional devices, including damping mechanisms, remain effective and functional even after position adjustments, ensuring smooth operation and effective guidance of the furniture pull-out, regardless of changes in the movable furniture part's position, by ensuring consistent contact and guidance between the functional elements.
Implementation Method 1
the bearing means having a hinge acting between the base section and the movement section
Implementation Method 2
one on the first and/or or second functional element has a guiding surface, via which the movable first functional element can be caught for subsequent guidance on the second functional element
