Drawer Pull-Out Guide With Spring-Reset Connection Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pull-out guides for drawers are difficult to reattach due to connection elements remaining in withdrawn positions, making reconnection laborious, especially when one side lacks an adjustment mechanism.
Innovation Solution
A pull-out guide with a holding element and connection element that can move between end positions, featuring a spring element to automatically reset the connection element to a neutral position when detached, allowing easy reconnection without tools and enabling lateral and height adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the connection element is mounted to be movable relative to the holding element without an adjustment mechanism on one side, then the device complexity is reduced, but the ease of operation deteriorates because the connection element remains in the withdrawn position and cannot be easily reset
Solution Approach 1:
The connection element is equipped with a spring element that automatically resets it to the neutral position when the drawer is removed. This self-service mechanism eliminates the need for manual resetting by the user, resolving the contradiction by maintaining simplicity while improving ease of operation through automatic functionality
Solution Approach 2:
The spring element is pre-configured to automatically return the connection element to the neutral position before the next installation. This preliminary action ensures the connection element is always ready for the next drawer attachment, solving the problem of difficult reconnection without adding complex adjustment mechanisms
2Ease of operation
If the connection element is spring-loaded to automatically reset to neutral position, then the ease of operation is improved, but the device complexity increases due to the additional spring element
Solution Approach 1:
The spring element provides automatic resetting functionality without requiring external control systems or complex mechanisms. This self-service approach improves ease of operation while minimizing the increase in device complexity by using a simple, reliable spring mechanism
Solution Approach 2:
The spring element introduces dynamic behavior to the otherwise static connection element, enabling automatic movement between positions. This dynamic feature improves ease of operation while keeping the complexity increase minimal, as the spring mechanism is a well-understood and simple component
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
Facilitates easy assembly, disassembly, and reconnection of drawers without tools, ensuring accurate positioning and stability through spring-loaded mechanisms and adjustment mechanisms, improving usability and efficiency.
Implementation Method 1
By now providing a spring element, by which the connection element is held in a neutral position which is located between the first end position and the second end position when it is not connected to the drawer

AI summary
A pull-out guide for a drawer has a body rail which can be attached to the furniture body and has at least one pull-out rail which can be moved relative to the body rail. The pull-out guide includes a holding element with at least one attachment member by which the holding element can be attached or is attached to the pull-out rail, and a connection element by which the drawer can be connected to the pull-out rail. The connection element is mounted such that it can be moved relative to the holding element between a first end position and a second end position. A spring element is provided, and the spring element holding the connection element in a neutral position located between the first end position and the second end position.
