Escalator Truss Device with Integral Inner Panel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional truss devices for escalators or moving walks are heavy and costly due to their composition of angle steel beams, and alternative two-panel designs lack sufficient load-supporting capacity and complexity in installation.
Innovation Solution
A truss device comprising an outer and inner panel, where the inner panel is a single integral panel with connection parts forming through openings for secure fixation, and a support part for load-bearing functions, eliminating the need for additional decorative and supporting components, and incorporating a profile member for enhanced stiffness and load support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional angle steel beams are used to form the truss device, then the load-supporting capacity is sufficient, but the weight and material cost increase significantly
Solution Approach 1:
The patent employs composite materials by combining an inner panel and an outer panel to form a truss device that achieves both lightweight construction and sufficient load-supporting capacity. The inner panel provides structural strength while the outer panel serves decorative and protective functions, eliminating the need for heavy angle steel beams.
Solution Approach 2:
The truss device is segmented into distinct functional components: an inner panel for structural support and an outer panel for decoration and protection. This segmentation allows each component to be optimized for its specific function, reducing overall weight while maintaining strength.
2Weight of stationary object
If two panels are used instead of angle steel beams, then the weight is reduced, but the load-supporting capacity becomes insufficient
Solution Approach 1:
The inner and outer panels are designed as composite structural elements that work together to provide both lightweight construction and adequate load-supporting capacity. The inner panel specifically bears the structural loads while the outer panel provides decorative and protective functions.
3Reliability
If decorative panel is added to wrap the truss device, then passenger safety is improved, but the weight and structural complexity increase
Solution Approach 1:
The decorative function is merged with the structural outer panel, eliminating the need for separate decorative panels. The outer panel simultaneously serves as a structural component, a decorative element, and a protective barrier, thereby reducing overall weight and structural complexity.
Solution Approach 2:
The outer panel is designed with multi-functionality, serving as both a structural element and a decorative panel. This universal component performs multiple functions that previously required separate components, reducing the overall weight and complexity of the truss device.
4Weight of stationary object
If two panels with flat surfaces are used, then the weight is reduced, but the ease of installation for functional components becomes difficult
Solution Approach 1:
The inner panel is segmented with multiple connection parts that extend toward the outer panel, creating through openings. These connection parts provide standardized interfaces that facilitate the easy installation of functional components such as step guides and chain guides.
Solution Approach 2:
The connection parts on the inner panel serve as intermediary elements that simplify the installation of functional components. These connection parts provide dedicated attachment points that make it easier to install functional components compared to working with flat panel surfaces.
