Pull-Out Guide Stop Device for Secure End Position Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pull-out guides for displaceable arrangements within a body lack simplicity and convenience in fixing end positions, often resulting in unwanted movement and obstruction due to the lack of effective stop mechanisms.
Innovation Solution
A pull-out guide with a stop device that includes stop elements on guide rails and rolling element cages, allowing for easy attachment and detachment, featuring multi-stage deformation sections for secure locking in both extended and pushed-in positions, and a self-closing mechanism to prevent undesired displacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a stop device with stop elements is added to the pull-out guide, then the reliability of end position locking is improved, but the device complexity increases
Solution Approach 1:
The stop elements are integrated directly into the guide rails and rolling element cages, merging the stopping function with the existing structural components. This eliminates the need for separate stop mechanisms while achieving reliable end position locking.
Solution Approach 2:
The stop elements automatically engage with the guide rails through multi-stage deformation when the pull-out reaches end positions, providing self-locking functionality without requiring external actuation or complex control mechanisms.
2Ease of operation
If stop elements are made elastic and flexible for secure attachment, then the ease of operation is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The stop elements utilize elastic deformation as a functional parameter, allowing them to flexibly engage with guide rails. The multi-stage deformation design transforms the elastic properties into controlled stopping forces at different compression stages.
Solution Approach 2:
The stop elements combine elastic materials with precise geometric features, creating a composite structure that provides both flexibility for easy attachment and controlled deformation characteristics for reliable stopping.
3Stability of the object's composition
If multiple stop elements are arranged on guide rails and rolling element cages, then the stability of end positions is improved, but the quantity of components increases
Solution Approach 1:
The stop elements serve multiple functions: they act as both stopping mechanisms and structural connectors between guide rails and rolling element cages. This multi-functionality reduces the need for separate components while maintaining end position stability.
Solution Approach 2:
The stop elements are integrated within the existing nested structure of the pull-out guide, with rolling element cages containing stop elements that interact with guide rails, creating a compact multi-functional assembly.

AI summary
In order to create a drawer slide for the slidable arrangement of a drawer that can be pulled out of a body on the body, which is of simple design and can be conveniently fixed in one or more end positions, it is proposed that the drawer slide comprises two or more guide rails, which can be moved along a drawer direction by means of rolling elements are arranged next to one another, the guide rails of the pull-out guide being able to be stopped in one or more end positions by means of a stop device of the pull-out guide.
