Cabinet Mounting Rail Fixation for Dynamic Load Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cabinet systems are inadequate in absorbing dynamic loads within interior fittings, requiring improved fixation methods to secure components like mounting rails and electrical outlet strips.
Innovation Solution
Geometric structures, such as cams, imprints, and perforations, are affixed to the cabinet housing's inner sides, providing a form-fitting connection and mechanical tension to securely hold components, with complementary structures on the mounting rail's supporting and tensioning sections, allowing for varied installation options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional mounting methods are used, then installation is simple, but dynamic loads cannot be absorbed effectively
Solution Approach 1:
The patent employs cam-shaped geometric structures with curved surfaces that engage with complementary curved surfaces on the mounting rail. This spherical/curved geometry enables automatic centering and uniform distribution of dynamic loads, transforming linear stress into radial compression that the curved surfaces can absorb effectively.
Solution Approach 2:
The fixation system incorporates a toggle lever mechanism that can dynamically adjust to load conditions. The lever pivots between locked and unlocked positions, allowing the mounting system to adapt to varying dynamic loads while maintaining secure attachment through geometric interlocking.
2Reliability
If geometric structures are added for load absorption, then dynamic loads are absorbed better, but manufacturing complexity increases
Solution Approach 1:
The cam-shaped geometric structures are designed with optimized curvature radii and engagement angles that balance load-bearing capacity with manufacturability. By carefully selecting geometric parameters, the patent achieves effective dynamic load absorption while keeping the structures compatible with standard manufacturing processes.
Solution Approach 2:
The geometric structures serve multiple functions simultaneously: they provide form-fitting connections for positional accuracy, create mechanical tension for load absorption, and act as positioning aids for component alignment. This multi-functionality reduces the need for separate features, simplifying manufacturing.
3Manufacturing precision
If form-fitting connections are used, then positioning accuracy is improved, but adaptability to different components is reduced
Solution Approach 1:
The mounting system divides the fixation function into separate geometric structures distributed at multiple locations along the mounting rail. Each cam-shaped structure acts as an independent positioning and load-bearing element, allowing the system to accommodate different component sizes and configurations while maintaining precise positioning through the collective action of segmented geometric features.
Solution Approach 2:
The standardized cam-shaped geometric structures serve as universal interface elements that can engage with various complementary structures on different components. This universal geometry provides consistent form-fitting connections and positioning accuracy across diverse applications while maintaining adaptability through flexible component selection.

AI summary
A cabinet system including a cabinet housing and at least one component for interior fittings, which has a mounting section with a first end and a second end spaced apart from the first end. The component is installed and held on the cabinet housing with a form-fitting connection and under mechanical tension by a supporting section at the first end and a tensioning section at the second end. Mounts are on an interior of at least one of walls, a floor, and a ceiling of the cabinet housing. The mounts are in engagement with structures that are at least partially complementary and located on at least one of the first end and the second end of the component. The at least partially complementary structures are on the supporting section and on the tensioning section. The tensioning section includes a toggle lever having an attachment side and a tensioning side.
