Facade Lifting System with Curved Guides and Stabilized Platform
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lifting and carrying systems for building facades are unable to accommodate complex, curved surfaces and lack the ability to stabilize the platform horizontally, making them unsuitable for buildings with intricate designs.
Innovation Solution
The system features rail- or mast-type guides that mimic the building's shape, attached to load-bearing structures, with a telescopic sectional platform and stabilization systems to maintain horizontal position, allowing adaptation to curved facades and ensuring safety through emergency locking and speed control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single vertical guide is used, then the system can maintain a stable vertical lifting path, but it cannot accommodate complex curved surfaces of modern building facades
Solution Approach 1:
The guide system is divided into multiple independent guide rails that can be positioned at different locations on the building facade. Each guide rail operates independently but works in coordination with the platform, allowing the system to adapt to complex curved surfaces while maintaining stable vertical lifting through each individual guide
Solution Approach 2:
The system transitions from a single vertical guide to multiple guides arranged in a spatial configuration that matches the building's curved facade. By adding horizontal and depth dimensions to the guide arrangement, the system can conform to three-dimensional curved surfaces while each guide maintains its vertical stability function
2Adaptability or versatility
If the guide shape is fixed to match the building, then the system can adapt to complex curved surfaces, but it cannot provide access to extended horizontal sections of the facade
Solution Approach 1:
The guide rails are designed with dynamic positioning capabilities, allowing them to be adjusted along the building facade to reach extended horizontal sections. The guides can be repositioned or extended horizontally while maintaining their curved configuration, providing both adaptability to the facade shape and access to horizontal areas
Solution Approach 2:
The guide system is designed to perform multiple functions: conforming to curved vertical surfaces, extending to horizontal facade sections, and providing stable lifting. The same guide structure serves both vertical adaptation and horizontal access requirements through its configurable design
3Ease of manufacture
If a simple platform design is used, then the system is easier to manufacture, but it cannot stabilize the horizontal position of the platform
Solution Approach 1:
The platform is divided into modular sections that can be manufactured separately and assembled on-site. This segmentation maintains manufacturing simplicity while allowing the integration of stabilization mechanisms in each module, such as horizontal positioning systems and alignment features
Solution Approach 2:
Intermediary stabilization mechanisms are introduced between the simple platform structure and the guide rails. These intermediaries include horizontal positioning systems, alignment devices, and stabilization components that connect the platform to the guides, providing horizontal stability without complicating the core platform design
4Ease of operation
If the platform shape is fixed, then the system is simpler to operate, but it cannot adjust to match the shape of the building facade
Solution Approach 1:
The platform incorporates dynamic shape-adjustment capabilities through telescopic sections and articulated joints that allow it to change its configuration. The platform can transform from a simple fixed shape to a complex curved shape that matches the building facade, while control systems maintain operational simplicity through automated adjustment sequences
