Angled Flank Protective Roof for Climbing Elevator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional climbing elevator systems face challenges in protecting components and passengers from falling objects and dirt during the construction phase, as existing protective roofs are difficult to install and require high construction effort for stability, often leading to gaps that allow objects to pass through.
Innovation Solution
The proposed elevator system features a protective roof designed with a central structure and peripheral flank structure, where the flank walls are angled to divert falling objects and are detachably fixed to the central roof, allowing for easy reassembly and adjustment as the lifting platform moves within the elevator shaft, minimizing gaps and ensuring stability with reduced material and construction effort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a conventional protective roof is installed above the lifting platform, then components and passengers are protected from falling objects, but the construction effort and material requirements increase significantly
Solution Approach 1:
The protective roof is divided into a central roof structure and multiple detachable flank structures that can be independently installed and removed. This segmentation allows the protective roof to be constructed with minimal material while maintaining effectiveness, as only the necessary central structure remains permanently installed.
Solution Approach 2:
The flank structures are designed to be detachably fixed to the central roof structure, allowing the protective roof configuration to dynamically adapt to the lifting platform's position. This enables easy reassembly and adjustment as the lifting platform moves within the elevator shaft, reducing permanent construction effort.
2Reliability
If a stable protective roof structure is created to prevent object passage, then protection effectiveness increases, but the device complexity and material usage increase
Solution Approach 1:
The protective roof is segmented into a simple central structure and separate flank structures. This reduces the complexity of any single component while maintaining overall protection effectiveness through the combined configuration.
Solution Approach 2:
Instead of creating a fully enclosed complex structure, the invention uses partial action by implementing only the necessary central roof and detachable flank structures. This provides sufficient protection against falling objects without the excessive complexity of a complete enclosure.
3Adaptability or versatility
If the lifting platform is displaced to extend the transport path, then the elevator system adapts to building construction progress, but the protective roof requires disassembly and reassembly increasing time loss
Solution Approach 1:
The protective roof is designed with detachable flank structures that can be easily assembled and disassembled. This dynamic configuration allows rapid reconfiguration when the lifting platform is displaced to new positions during building construction, minimizing time loss.
Solution Approach 2:
By segmenting the protective roof into a permanent central structure and temporary flank structures, the system enables quick reassembly at new positions. Only the flank structures need to be detached and reattached, significantly reducing the time required compared to moving an entire integrated protective roof.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The angled flank structure effectively diverts falling objects, enhances mechanical stability, and simplifies installation and reassembly, providing comprehensive protection with lower construction effort and minimal gaps for object passage.
Implementation Method 1
The flank structure has flank walls (27) which are fixed to the roof structure (23), in particular to lateral edges (30) of the roof structure (23), and which are arranged to project outward from the central roof structure (23) at an angle with respect to the horizontal

AI summary
A climbing elevator system has an elevator shaft and an elevator car, a lifting platform, and a supporting device, wherein, in the course of different construction phases of a building, the lifting platform can be anchored at various positions within the elevator shaft. A protective roof is arranged above components of the lifting platform that are to be protected, such as a drive machine. The protective roof has a central roof structure and a peripheral flank structure that has flank walls fixed to the lateral edges of the central roof structure and project outwardly from the central roof structure at an angle with respect to the horizontal. Because of the inclined arrangement of the flank walls, the flank structure can better withstand falling objects and better protect components located underneath. Cantilevered edge regions of the flank walls can be supported on side walls of the elevator shaft.
