Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing crane internal climbing systems lack flexibility and stability, particularly when dealing with complex building designs and varying opening sizes, posing safety risks and inefficiencies in construction sites.
Innovation Solution
A system comprising a supporting platform reversibly mounted to the tower with rotatable outrigger arms and a climbing ladder, allowing for flexible repositioning of the crane by extending and retracting the main platform, and connecting to repositionable support brackets for enhanced stability and adaptability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If rigid frame structures are used to increase stability during internal climbing, then stability is improved, but flexibility and adaptability to different building configurations deteriorate
Solution Approach 1:
The climbing system is divided into modular components including a frame assembly, climbing assembly, and support brackets that can be independently positioned and configured. This segmentation allows the system to maintain structural stability while adapting to different building geometries and opening sizes.
Solution Approach 2:
The support brackets are designed to be repositionable along the building structure, and the climbing assembly can be adjusted to different heights and angles. This dynamic configurability enables the system to adapt to various building configurations while maintaining stability during the climbing process.
2Stability of the object's composition
If the tower fits tightly and precisely to the building structure to maintain stability, then stability is improved, but adaptability to different opening sizes and complex building designs deteriorates
Solution Approach 1:
The support brackets are designed with universal adaptability to engage with different building structures and configurations. They can be positioned at various locations and orientations, allowing the same climbing system to work across different opening sizes and building designs without requiring custom-fit components.
Solution Approach 2:
The system allows for adjustment of key parameters including bracket position, climbing angle, and platform height. These parameter changes enable the climbing assembly to adapt to different opening dimensions and building geometries while maintaining stable operation throughout the climbing process.
3Adaptability or versatility
If reconfigurations of components are performed to accommodate different building opening sizes, then adaptability is improved, but device complexity and time consumption increase
Solution Approach 1:
The support brackets are pre-configured with multiple engagement positions and orientations, allowing quick adaptation to different building configurations without requiring complex reconfiguration of the entire climbing system. The modular design enables rapid deployment for various opening sizes.
4Stability of the object's composition
If sufficient fixed support is provided to maintain tower stability, then stability is improved, but the complexity of the support system increases
Solution Approach 1:
The climbing system utilizes the building structure itself as the support source, with repositionable support brackets that engage directly with existing building elements. This eliminates the need for separate, complex external support systems while maintaining adequate stability during the climbing operation.
