3D Concrete Printer for Modular Escalator Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing passenger transport systems, such as escalators and moving walkways, are large and bulky, making it difficult to install them in existing buildings without demolishing parts of the building shell, and their transport requires significant resources and causes traffic obstructions.
Innovation Solution
A printer device comprising a printer guide device and a 3D concrete printer device is used to create a concrete structure for the passenger transport system within an existing building, allowing the load-bearing structure to be built directly in the building, reducing transport volume and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If passenger transport systems are manufactured as complete large components, then installation precision and structural integrity are improved, but transport volume and building demolition requirements increase
Solution Approach 1:
The patent divides the load-bearing structure into multiple transportable modules that can be assembled on-site. Each module contains complete functional units (steps, drive mechanisms, support structures) that maintain structural integrity while reducing individual component size for transport. The modules are designed with standardized connection interfaces to ensure precise assembly without requiring complete demolition of building structures.
2Loss of time
If passenger transport systems are transported as complete assembled units, then assembly time on-site is reduced, but transport costs and traffic obstructions increase
Solution Approach 1:
The system is segmented into modular units that can be transported efficiently using standard logistics infrastructure. The modules are compacted during transport and quickly assembled on-site using pre-engineered connection mechanisms, significantly reducing both transport resource requirements and on-site assembly time compared to transporting complete assembled units.
3Volume of moving object
If the load-bearing structure is subdivided into modules, then transportability is improved, but material usage and assembly complexity increase
Solution Approach 1:
The load-bearing structure is divided into standardized modules with uniform dimensions and pre-configured connection interfaces. Each module is self-contained with integrated components, reducing the need for additional fastening elements and simplifying the assembly process despite the increased number of components.
Solution Approach 2:
The modules are designed with universal connection interfaces and standardized dimensions that allow them to be used in various configurations and locations. This multi-functionality reduces the need for custom-designed connection elements for each module, thereby reducing overall material usage and assembly complexity.
4Volume of moving object
If interface points of modular load-bearing structures are created, then transportability is improved, but load-bearing capacity and reinforcement requirements increase
Solution Approach 1:
The interface points between modules are designed with integrated reinforcement elements and pre-stressed connection mechanisms that distribute loads evenly across the joint. This ensures that the load-bearing capacity at interface points matches or exceeds that of continuous structures, eliminating the need for additional reinforcement while maintaining transportability.
