Drawer Guide Rail Mount With Tool-Free Height and Side Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for attaching guide units to movable furniture parts, such as drawers, lack flexibility in adjusting the height and lateral position, limiting the precise alignment and inclination of furniture components.
Innovation Solution
A device featuring a hook element with a hook nose at the rear end of the movement rail and an adjustable receiving device that allows vertical and horizontal adjustments, enabling precise positioning of the furniture part by engaging the hook element in a recessed area, which can be adjusted using mechanisms like eccentric fixation or screw-based systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed hook element is used to attach the movement rail to the furniture part, then the attachment is simple and secure, but the height and lateral position cannot be adjusted
Solution Approach 1:
The receiving device is made adjustable along the movement rail, transforming a static attachment system into a dynamic one. The receiving element can be positioned at different locations on the rail, enabling height and lateral position adjustment of the furniture part while maintaining a relatively simple overall structure.
Solution Approach 2:
The attachment device is divided into separate functional components: a fixed hook element on the furniture part and an adjustable receiving device on the movement rail. This segmentation allows independent adjustment of the receiving device without affecting the hook element, providing flexibility while keeping each component simple.
2Manufacturing precision
If traditional fixed mounting is used, then the structure is simple, but precise alignment and inclination adjustment are not possible
Solution Approach 1:
The adjustment mechanism is designed to be operable without tools. The receiving element can be manually moved along the movement rail and fixed at desired positions, allowing users to perform alignment and inclination adjustments directly during installation or maintenance without requiring additional tools.
Solution Approach 2:
The system allows dynamic adjustment of the receiving device position along the movement rail, enabling precise alignment and inclination settings. The movable receiving element can be positioned at any location on the rail, providing continuous adjustment capability for precise positioning.
3Adaptability or versatility
If the receiving device is made adjustable along the movement rail, then positioning flexibility is improved, but the device complexity increases
Solution Approach 1:
The receiving device incorporates a movable receiving element that can be positioned at different locations on the movement rail. This dynamic component provides positioning flexibility while maintaining a relatively simple overall structure by using basic mechanical elements rather than complex mechanisms.
Solution Approach 2:
The adjustable receiving device is segmented into the receiving element and the movement rail interface. This segmentation allows the receiving element to be independently adjusted along the rail while keeping the overall attachment mechanism simple and maintainable.
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
Enables easy height and lateral adjustment of furniture parts, allowing for precise alignment and inclination without the need for tools, ensuring secure and customizable positioning within the plane of multiple drawer fronts.
Implementation Method 1
The displacement means can, for example, comprise a gear and be designed in the form of an eccentric fixation with an eccentrically mounted bolt or pin
Implementation Method 2
or a worm displacement with a worm and worm wheel
Implementation Method 3
An embodiment with a slot and a clamping screw is also conceivable
