Hinged Connector Assembly for Slotted Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of aircraft systems and varying needs of airlines pose a challenge in providing flexible wiring options, as existing connector assemblies for attaching fasteners to slotted surfaces are inflexible and difficult to install, requiring custom modifications and tools, which are costly and impractical for reconfiguration.
Innovation Solution
A connector assembly comprising a base shell and a clasp shell, hingedly attached, which can be moved between open and closed positions to latch onto a slotted surface, allowing for tool-less installation and versatile mounting of wiring and cabling support elements without modifying the seat track geometry, using a threaded insert for attaching wire, conduit, or cable supports.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing connector assemblies are used to attach fasteners to slotted surfaces, then structural attachment is achieved, but flexibility and ease of installation deteriorate due to requiring custom modifications and tools
Solution Approach 1:
The connector assembly is divided into separate components including a connector body, clasp mechanism, and threaded insert that can be independently manufactured and assembled. This segmentation allows each component to be optimized for its specific function while maintaining overall flexibility and ease of installation.
Solution Approach 2:
The connector assembly is designed as a universal attachment mechanism that can be used with various slotted surfaces and fastener types. The standardized connector body with clasp mechanism and threaded insert provides multi-functional capability across different wiring configurations and installation locations.
2Strength
If existing connector assemblies require custom modifications and tools, then attachment strength is achieved, but device complexity and cost increase
Solution Approach 1:
The connector assembly incorporates self-contained features including an integrated clasp mechanism for self-latching and a threaded insert for self-tapping into the slotted surface. This self-service design eliminates the need for external custom tools or modifications, reducing device complexity while maintaining attachment strength.
Solution Approach 2:
Multiple functions are merged into a single integrated connector assembly: the connector body provides structural support, the clasp mechanism provides latching, and the threaded insert provides fastener attachment. This consolidation eliminates the need for separate custom tools and modifications.
3Reliability
If existing connector assemblies are used, then fastener attachment is achieved, but installation time and productivity deteriorate due to difficult installation
Solution Approach 1:
The threaded insert is pre-installed into the connector body during manufacturing, and the clasp mechanism is pre-configured for automatic engagement. This preliminary action eliminates the need for on-site threading operations or complex assembly steps, significantly improving installation speed while maintaining attachment reliability.
Solution Approach 2:
The clasp mechanism automatically latches onto the slotted surface when the connector is inserted, and the threaded insert self-taps into the surface without requiring separate fastening operations. This self-service capability accelerates installation while ensuring reliable fastener attachment.

AI summary
A connector assembly for installation to a surface having a slot pattern. The connector assembly includes a base shell and a clasp shell. The clasp shell movable relative to the base shell between an open position and a closed position, and one of the base shell and the clasp shell includes a threaded insert spaced from an end of the connector.
