Rail Assembly Carriage Slider Bracket Ramp Portions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current rail assemblies for mounting seating assemblies to vehicles lack enhancements in operation, particularly in terms of support and adjustability, leading to limitations in flexibility and load distribution.
Innovation Solution
A rail assembly design featuring a track assembly with an elongate shaft and a carriage assembly, including a slider bracket with ramp portions and a gear box, which allows for adjustable positioning and support of seating assemblies through a support assembly with an engagement feature that can move between deployed and retracted positions, providing enhanced support and load transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional rail assembly is used for mounting seating assemblies, then the structure is simple, but the adjustability and support capability are limited
Solution Approach 1:
The rail assembly is divided into multiple functional segments: track assembly, elongate shaft, carriage assembly, slider bracket, gear box, and support assembly. Each segment performs a specific function, allowing independent optimization and adjustment while maintaining overall system adaptability.
Solution Approach 2:
The support assembly includes an engagement feature that can move between deployed and retracted positions, providing dynamic adjustability. The slider bracket with ramp portions enables dynamic positioning of the elongate shaft, allowing the system to adapt to different seating configurations and load conditions.
2Strength
If a traditional rail assembly is used, then the device complexity is low, but the load distribution capability is insufficient
Solution Approach 1:
The engagement feature acts as an intermediary between the support assembly and the elongate shaft, transferring and distributing loads efficiently. The slider bracket serves as a mediator that facilitates controlled movement and positioning while managing mechanical stresses during adjustment operations.
Solution Approach 2:
The support assembly integrates multiple functions: structural support, load bearing, and adjustable positioning. The carriage assembly combines the slider bracket, gear box, and engagement mechanism into a single integrated unit that performs multiple operations simultaneously, improving load distribution while managing complexity.
3Reliability
If the support assembly is in the deployed position, then the support capability is maximized, but the flexibility in positioning is reduced
Solution Approach 1:
The support assembly can periodically transition between deployed and retracted states, providing maximum support capability when needed (deployed) and flexibility when repositioning is required (retracted). This periodic action allows the system to alternate between stability and adaptability based on operational requirements.
Solution Approach 2:
The engagement feature's ability to move between deployed and retracted positions creates a dynamic system that can adapt its support characteristics in real-time. When in the deployed position, the engagement feature provides rigid support for maximum reliability; when retracted, it allows flexible repositioning of the carriage assembly along the track.

AI summary
A rail assembly can include a track assembly, an elongate shaft mounted to the track assembly, and a carriage assembly received within the track assembly. The carriage assembly can include a slider bracket. The slider bracket includes a first ramp portion and a second ramp portion. The first and second ramp portions are disposed on opposite sides of the slider bracket. The first and second ramp portions each define a receiving aperture. The elongate shaft is received through the receiving apertures of the first and second ramp portions.
