Modular Mast Platform Asynchronous Lifting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing platform support devices are inadequate for reaching great heights safely and efficiently, as they either restrict the raising height due to mast anchoring, require synchronous movement of multiple masts, or are unsafe during vertical movement.
Innovation Solution
A platform support device with modular, independent masts that allow asynchronous movement of platforms along guide paths, enabling the use of fewer masts and optimizing assembly/disassembly times, where each mast can be anchored to the structure without hindering vertical movement, and featuring hoist-type lifting elements and temporary immobilization mechanisms for adjusting height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If masts are anchored to the facade to prevent overturning, then stability is improved, but the raising height is limited because anchor pieces indicate the end of raising
Solution Approach 1:
The mast is divided into multiple modular elements that can be assembled sequentially. Each element can be attached independently, allowing the mast to grow in height without requiring re-anchoring. The anchor piece is designed to work with individual modular elements rather than limiting the entire mast height.
Solution Approach 2:
The system transitions from a static anchored structure to a dynamic, extendable structure. The modular elements allow the mast to adapt its height dynamically based on work requirements, while the anchoring system remains capable of securing each segment independently.
2Length of moving object
If multiple masts are used to reach great heights, then height capability is improved, but assembly and disassembly time increases
Solution Approach 1:
The mast is segmented into standardized modular elements that can be quickly assembled and disassembled. Each element is designed with connection features that enable rapid attachment and detachment, reducing the time required for assembly operations.
Solution Approach 2:
The modular elements are pre-designed with standardized connection interfaces and attachment features. This preliminary design work enables workers to quickly assemble the mast by simply connecting pre-fabricated segments rather than constructing the structure from raw materials during installation.
3Reliability
If masts are joined to the facade with anchor pieces, then stability is improved, but the platform cannot be lowered completely when masts are dismantled
Solution Approach 1:
The anchoring system is segmented to work with individual modular mast elements rather than the entire mast structure. This allows the anchor to be detached and relocated as each modular element is removed during dismantling, enabling complete platform lowering.
Solution Approach 2:
The anchor pieces are designed to be temporarily attached during operation and then easily detached during dismantling. The anchoring system is recovered and can be reused with subsequent modular elements, rather than being permanently fixed to the facade.
4Reliability
If synchronous movement of multiple masts is required, then platform stability is improved, but operational flexibility deteriorates
Solution Approach 1:
Each mast is segmented into independent modular elements with individual hoisting mechanisms. This segmentation allows any combination of elements to be raised or lowered independently, enabling both synchronous operation for stability and asynchronous operation for flexibility based on work requirements.
Solution Approach 2:
The system transitions from rigid synchronous movement to dynamic, selectable movement patterns. The modular architecture with independent hoists enables the platform to operate in synchronous mode when stability is needed or in asynchronous mode when accessing different facade areas, providing operational adaptability.

AI summary
A device supports a platform that is used to lift loads or persons the height of a structure. Together with a platform, the device includes winch-type platform-lifting elements and modular mast-forming elements. Each mast element is attached using the load platform which can be connected to the masts by: (i) the winch-type lifting elements which can be disconnected at will from the masts, and (ii) elements for temporarily blocking the movement of the platform in relation to a modular element of each mast. In this way, when the movement of the platform is blocked, a modular element can be added to, or removed from the top of the masts in accordance with the desired platform lifting height. The platform is positioned between two modular independent masts which form a lifting and guiding path.
