Rail Coupling Device with Floating Plate for Stress Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coupling devices for attaching equipment to aircraft rails subject equipment to high mechanical stresses, leading to potential deterioration and deformation due to fixing forces, and fail to provide easy, precise, and stress-reduced attachment solutions.
Innovation Solution
A coupling device with a main body attached to the rail and a connecting member featuring a floating plate that can move freely relative to the main body, allowing adjustment and locking to minimize stress through a locking/unlocking mechanism and adjustment means, enabling precise positioning and stress reduction.

Engineering Contradiction Analysis
1Stability of the object's composition
If equipment is fixed to rails using traditional coupling devices, then stable attachment is achieved, but high mechanical stresses cause equipment deterioration and deformation
Solution Approach 1:
The coupling device is divided into separate functional components: a fixing body attached to the rail and a connecting member with floating plates that attaches to the equipment. This segmentation allows the fixing forces to be distributed and absorbed by the rail structure rather than concentrated on the equipment, reducing mechanical stress while maintaining attachment stability.
Solution Approach 2:
The floating plates act as intermediaries between the rigid rail fixation system and the equipment. These plates can move freely relative to the fixing body, absorbing mechanical stresses and preventing them from being transmitted to the equipment, thus protecting it from deterioration and deformation.
2Stability of the object's composition
If rigid fixing is used to ensure stable attachment, then equipment stability improves, but adjustment precision and positioning flexibility are reduced
Solution Approach 1:
The connecting member incorporates floating plates that can move freely relative to the fixing body, providing dynamic adjustment capability. This allows precise positioning of the equipment while maintaining stable attachment, as the floating plates can be adjusted to the desired position and then locked in place.

AI summary
The device (1) has a main body (2) attached to a rail, and a connection body attached to the main body. The connection body has a plate (4) mounted on the main body. A locking/unlocking unit (7) varies between a locking configuration in which the locking/unlocking unit immobilizes the plate in an instantaneous position that the plate occupies at the moment where the locking/unlocking unit adapts its locking configuration, and an unlocking configuration in which the locking/unlocking unit leads the plate free from being displaced relative to the main body.
