Profile Load-Bearing Connection for Precise Track Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing support structures for track devices, such as escalators, have large manufacturing tolerances due to welding, making it complex and laborious to position and align components correctly, requiring manual creation of fastening means for variable positioning.
Innovation Solution
A load-carrying device with a profile featuring a first wall and an angular second wall, including a connecting piece that passes through a recess on the second wall to rest against the first wall, providing a load-resistant connection for safe and distributed force dissipation, and allowing for flexible alignment and easy attachment during assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If profiles are welded together to form support structures, then structural strength is achieved, but manufacturing tolerances become large
Solution Approach 1:
The support structure is divided into separate profile sections that are connected through load-bearing devices with connecting pieces, rather than being welded into a single integrated structure. This segmentation allows each component to be manufactured separately with precise tolerances while maintaining overall structural strength.
Solution Approach 2:
Load-bearing devices with connecting pieces serve as intermediary elements between profile sections. These connecting pieces insert into recesses and provide precise positioning and alignment, acting as mediators that transfer loads while maintaining manufacturing precision across multiple assembled components.
2Manufacturing precision
If complex positioning and alignment procedures are used, then component positioning accuracy is improved, but assembly complexity increases
Solution Approach 1:
The connecting pieces are designed with built-in positioning features and alignment guides that automatically establish correct positions during assembly. The recesses and connecting piece geometries are pre-configured to provide self-aligning capabilities, eliminating the need for complex external positioning procedures.
Solution Approach 2:
The load-bearing devices and connecting pieces are designed to self-position and self-align during assembly. The geometric constraints of the recesses and connecting piece shapes automatically guide correct positioning without requiring external gauges or complex alignment procedures.
3Adaptability or versatility
If manual creation of fastening means is required, then variable positioning capability is achieved, but assembly time increases
Solution Approach 1:
The connecting pieces are designed with movable or adjustable features that allow variable positioning during assembly. The connecting pieces can be positioned at different locations along the profiles while maintaining secure connections, providing adaptability without requiring manual creation of fastening means.
