Cable Tray Anchoring Element With Folded Bar For Oscillation Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable tray connection systems require multiple operators and additional accessories, making them difficult to assemble securely, especially in high locations, and lack stability during traction or oscillations.
Innovation Solution
The integration of a folded anchoring element with angled branches into the cable tray sections allows for secure, one-operator assembly without additional accessories, ensuring sections remain connected even under stress or oscillation by sliding the transverse bar into a gap formed by the anchoring element's inward and outward bends.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connection systems use staples or elements requiring complementary screws or nuts, then the connection can be secure, but the assembly becomes difficult and requires more than one operator
Solution Approach 1:
The anchoring element merges multiple functions into a single integrated component: the folded bar provides structural support, the extensions provide attachment points, and the bends create the locking mechanism. This eliminates the need for separate staples, screws, or nuts, allowing one operator to assemble the connection by simply pressing sections together.
Solution Approach 2:
The anchoring element is self-contained and self-activating. When the tray section is pressed against the anchoring element, the transverse bar automatically slides along the branches and falls into the gap between the first bend and the first transverse bar, creating a secure connection without requiring additional tools or accessories.
2Ease of operation
If traditional anchoring elements are used, then assembly is simple, but the connection lacks stability under traction or large oscillations
Solution Approach 1:
The anchoring element uses asymmetric geometry with branches at different inclinations rather than symmetric parallel bars. This asymmetric configuration creates a mechanical interlock where the transverse bar falls into a specifically positioned gap, preventing detachment under traction or oscillation while maintaining simple assembly through direct pressing.
Solution Approach 2:
The anchoring element employs curved bends instead of straight lines. The first bend and second bend create a gap structure that receives and secures the transverse bar. These curved geometric features provide mechanical stability under dynamic loads while allowing simple press-fit assembly without complex fastening mechanisms.
3Reliability
If additional accessories are used for connection, then the connection can be more secure, but the device complexity increases
Solution Approach 1:
The anchoring element serves multiple functions within a single component: it provides structural support through the folded bar, creates attachment points through extensions, and forms a locking mechanism through bends. This multi-functional design eliminates the need for multiple separate accessories, reducing device complexity while maintaining secure connection.
