Solution Overview
Problem
Existing guidance systems for sliding elements, such as furniture or kitchen appliances, face challenges in achieving high mechanical loading capacity while maintaining economical manufacturing and space efficiency, particularly in withstanding static and dynamic loads.
Innovation Solution
A guidance system comprising a guide rail and a sliding element rail, where a carriage is arranged between them, featuring a recess on the guide rail for a bearing body that secures the sliding element rail, allowing for relative movement and bracing against the guide rail, thus enhancing stability and load-bearing capacity without significant material usage or space compromise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional guidance systems use more material and larger components to withstand high loads, then mechanical loading capacity is improved, but manufacturing cost and space requirements increase
Solution Approach 1:
The guidance system is divided into modular components: a carriage with separate bearing bodies for different movement phases, a guide rail with specifically designed recesses, and a sliding element rail with bracing elements. This segmentation allows each component to be optimized for its specific function, achieving high load capacity with minimal material in each segment
Solution Approach 2:
The bearing bodies are designed to dynamically change their function during the movement cycle: they provide rolling support during movement, then engage with the bracing elements to provide rigid support during the braced phase. This dynamic adaptation allows the system to withstand high loads only when needed, reducing overall material requirements
2Reliability
If traditional guidance systems use larger components to ensure stability under load, then reliability is improved, but the space required for installation increases
Solution Approach 1:
The bracing elements extend perpendicular to the plane of movement, utilizing the third dimension to provide support. The bearing bodies engage with these bracing elements from above, creating a stable structure without increasing the footprint or movement space of the guidance system
3Stability of the object's composition
If traditional guidance systems use complex structures to prevent joint pattern changes, then stability is improved, but manufacturing complexity increases
Solution Approach 1:
The bearing bodies automatically engage with the bracing elements through their own weight and the movement dynamics of the sliding element. The recesses in the guide rail and the bracing elements on the sliding element rail are positioned so that engagement occurs automatically during normal operation, eliminating the need for complex adjustment mechanisms or additional fastening devices

Function Achieved in This Case
The solution provides a material-saving, highly stable guidance system that effectively withstands high loads and is space-efficient, ensuring secure mounting and smooth operation of sliding elements, preventing joint pattern changes and tilting due to weight, while allowing easy installation and manufacturing.
Implementation Method 1
a movement element of the carriage is movably guided on the running surface in the mounted condition of the guidance system
Implementation Method 2
the sliding element rail is braced against the guide rail, which prevents a change in the joint pattern

AI summary
A guidance system including a guide rail and a sliding element rail, and designed to movably connect a linearly movable sliding element to a body. A carriage is arranged between the rails so that the sliding element rail is movable relative to the guide rail. The guide rail includes a running surface on a top side and/or on a bottom side. A movement element of the carriage is movably guided on the running surface. The top side of the guide rail is provided opposite to and spaced apart from the bottom side of the guide rail. The guide rail has a recess on the top side and/or on the bottom side in an end segment of the guide rail, through which a bearing body protrudes, and attachment means are provided in the area of the recess in order to mount the bearing body.
