Track-Mounting Assembly With Interleaved Tongues And Elastic Jacket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing track-mounting assemblies face challenges in adjusting resistance to displacement in vertical, transverse, and longitudinal directions, as they are difficult to customize for varying loads, and current solutions do not effectively differentiate between these directions.
Innovation Solution
A track-mounting assembly featuring a track plate with longitudinally extending tongues and a base plate with interleaved tongues, an elastic jacket between them, which provides varying resistance by compressing between the track plate and substrate, allowing for distinct resistance profiles in different directions and acting as an electrical insulator and protective layer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an elastomeric cushion is provided between two plates to control the amount of give, then the assembly permits relative movement of the plates, but it is difficult to adjust the resistance to displacement of the rail in different directions (vertical, transverse, longitudinal)
Solution Approach 1:
The elastomeric cushion is provided with recesses at specific locations that engage with protrusions on the base plate, creating localized zones of varying resistance. This allows different directions (vertical, transverse, longitudinal) to have different resistance characteristics while using a single elastomeric component, thus achieving directional adaptability without significantly increasing overall assembly complexity.
2Stability of the object's composition
If the track plate is directly secured to the base plate, then the assembly is simple and strong, but it does not permit relative movement between the plates
Solution Approach 1:
An elastomeric cushion is introduced as an intermediary element between the track plate and base plate. This cushion provides both mechanical coupling (maintaining stability) and elastic deformation capability (permitting relative movement). The recesses in the cushion engage with protrusions on the base plate to guide and control the movement while maintaining a stable connection.
3Force
If the elastomeric cushion is compressed between the track plate and substrate, then it provides stiff resistance after initial deflection, but the initial resistance is soft requiring a predetermined downward movement
Solution Approach 1:
The elastomeric cushion is segmented with recesses that engage with protrusions on the base plate, creating a progressive compression mechanism. As the track plate moves downward, the cushion compresses in stages, with the recesses providing structural support points. This segmentation allows the cushion to provide initial soft resistance for rail adjustment while progressively increasing to stiff resistance, reducing the overall downward movement distance required.

Function Achieved in This Case

AI summary
An assembly for mounting a longitudinally extending track on a substrate has a track plate having a top face adapted to carry the track and formed unitarily below the top face with a plurality of longitudinally extending tongues, a base plate at least partially below the track plate, adapted to be anchored to the substrate, horizontally surrounding the tongues of the track plate, and formed with a plurality of longitudinally extending tongues transversely spaced from, longitudinally interleaved with, and horizontally at least partially level with the tongues of the track plate. The track plate and base plate are wholly out of direct engagement with and spaced vertically and/or horizontally from each other. An elastic jacket or liner is engaged between the plates and between the tongues of the track plate and the tongues of the base plate.
