Bracket Securing Element for C-Rail Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing C-rail assembly systems are prone to bending open under high loads, leading to the potential detachment of add-on parts, as they lack sufficient stability to withstand significant loads.
Innovation Solution
A bracket-shaped securing element is positioned between the add-on part and the C-rail's gripping strips, overlapping the C-rail's lateral legs to prevent bending, and can be integrated with screw connections like cap screws or hammer head screws, enhancing the C-rail's stability by locally clamping and supporting its legs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a standard screw connection is used to fasten add-on parts to the C-rail, then the assembly system is simple and easy to manufacture, but the C-rail bends open under high loads causing add-on parts to detach
Solution Approach 1:
The securing element is divided into two functional legs (first leg and second leg) that independently engage with the C-rail's gripping strips. This segmentation allows each leg to provide localized reinforcement, collectively preventing the C-rail from bending open under load while maintaining a relatively simple overall structure.
Solution Approach 2:
The securing element extends in a direction transverse to the longitudinal axis of the C-rail, creating a dimensional reinforcement that restricts the bending movement of the C-rail legs. This transverse extension adds a new spatial dimension to the load-bearing capability, preventing the C-rail from deforming open under high loads.
2Reliability
If the C-rail is reinforced to prevent bending under high loads, then the stability and reliability improve, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The securing element acts as an intermediary component between the add-on part and the C-rail. It transfers and distributes the loads from the add-on part to the C-rail in a manner that prevents bending, thereby improving reliability without requiring modifications to the C-rail itself or complex manufacturing processes.
Solution Approach 2:
The securing element is positioned within the space defined by the C-rail's gripping strips, with its legs extending into the interior space of the C-rail. This nested arrangement allows the securing element to provide reinforcement without adding significant external complexity or requiring complex manufacturing operations.
3Stability of the object's composition
If the securing element extends far beyond the attachment point, then the C-rail stability improves along its length, but the weight and material usage increase
Solution Approach 1:
The securing element provides localized reinforcement at critical points along the C-rail where bending is most likely to occur. Rather than uniformly strengthening the entire C-rail, the securing element concentrates its structural support where needed, minimizing unnecessary material usage and weight while maintaining stability.
Solution Approach 2:
The securing element extends slightly beyond the immediate attachment point to provide adequate reinforcement, but not excessively so. This partial extension is sufficient to prevent C-rail bending under load while avoiding the unnecessary weight and material consumption that would result from excessive extension.

AI summary
The invention relates to an assembly system (100; 100') for securing an attachment part (8) to a C-rail (1), which has two laterally arranged limbs (2, 3) and two surrounding strips (4, 5) which face the attachment part (8) and are arranged at a distance from each other, said attachment part (8) being pressable against the outer surfaces (28) of the two surrounding strips (4, 5) of the C-rail (1) by means of a screw connection (7; 7'). In order to prevent the C-rail (1) from bending under high loads, the invention proposes a bracket-shaped securing element (17) which is arranged between the attachment part (8) and the surrounding strips (4, 5) when the assembly system (100; 100') is used as intended such that the two limbs (18, 19) of the bracket-shaped securing element (17) at least partly surround the outside of the two laterally arranged limbs (2, 3) of the C-rail (1).
