Bonded Pull-Out Guide Profile for Higher Rigidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Strip-shaped profiles for pull-out guides face challenges in achieving high stability while maintaining compact geometry and minimizing material usage, especially in lateral direction, which affects their ability to absorb loads and resist deformation.
Innovation Solution
The solution involves fixing at least one edge section of a metal strip to an adjacent section using a non-detachable connection, such as gluing, welding, or reshaping, to increase rigidity and allow for reduced material thickness, thereby enhancing the profile's ability to absorb loads and resist torsional loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the material thickness of the strip-shaped profile is increased to ensure adequate lateral stability, then the lateral stability is improved, but the mass and material costs increase
Solution Approach 1:
The strip-shaped profile is segmented into multiple sections (edge sections and adjacent sections) that are materially bonded together. This segmentation allows each section to contribute to the overall lateral stability while using thinner individual sections, reducing total material usage and mass compared to a single thick-section profile.
Solution Approach 2:
The profile uses a composite structure where multiple metal strip sections are materially bonded together to form a composite profile. This composite construction achieves high lateral stability through the combined effect of multiple bonded sections rather than relying on increased thickness of a single section, thereby reducing mass and material costs.
2Strength
If the material thickness of the strip-shaped profile is increased to prevent deformation under load, then the rigidity is improved, but the material costs and mass increase
Solution Approach 1:
The profile is divided into multiple sections that are materially bonded together. This segmentation creates a composite structure where the combined rigidity of bonded sections exceeds that of a single section of equivalent total material, achieving high rigidity with reduced material usage.
Solution Approach 2:
Multiple metal strip sections are materially bonded to form a composite profile structure. This composite construction achieves superior rigidity through the synergistic effect of bonded sections, allowing the use of thinner individual sections and reducing overall material consumption while maintaining or enhancing rigidity.
3Strength
If a non-detachable connection is used to fix edge sections to adjacent sections, then the rigidity and load-absorbing capacity are improved, but the manufacturing complexity increases
Solution Approach 1:
The manufacturing process merges the bending and fixing operations into an integrated continuous flow process. The metal strip is bent into the desired cross-section and immediately materially bonded in the same production line, combining multiple operations without requiring separate assembly steps, thereby managing manufacturing complexity while achieving high load-absorbing capacity.
Solution Approach 2:
The invention replaces traditional mechanical fastening methods (such as screws or clips) with material bonding processes (such as welding, adhesive bonding, or diffusion bonding). This substitution eliminates the need for additional mechanical fastening components and assembly steps, reducing manufacturing complexity while achieving superior rigid connections with high load-absorbing capacity.
4Stability of the object's composition
If the profile geometry is modified to increase lateral stability, then the stability is improved, but the installation space increases
Solution Approach 1:
The profile uses a composite structure of materially bonded sections that achieves high lateral stability through the bonding mechanism rather than through increased geometric dimensions. This allows the profile to maintain a compact cross-sectional area and minimal installation space while attaining the required lateral stability through the combined effect of bonded sections.
Solution Approach 2:
The invention changes the structural parameters of the profile by introducing material bonding between sections rather than relying solely on geometric parameters (such as increased thickness or larger cross-section). This parameter change enables the achievement of high lateral stability with a compact geometry that requires minimal installation space.

AI summary
A strip-like profile (1,1', 1", 1' ", 1" ") for a pull-out guide is formed from a bent metal strip, wherein bent portions (2, 4, 5, 6, 8, 9, 10, 14, 15) are provided in a central region of the metal strip in order to form at least one running path (25) for rolling bodies which are arranged between edge portions (6, 10) of the metal strip. According to the invention, at least one edge portion (6, 10) of the metal strip is fixed to an adjacent portion (2) of the metal strip. As a result, the rigidity of the profile can be improved in an effective manner. The invention also relates to a pull-out guide with a profile of this type and to a method for producing said profile.
