Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elevator construction methods face challenges in safely and efficiently installing and repositioning hoisting arrangements, particularly in jump-lifts, due to difficulties in finding reliable support points and the need for special structures like guide rails or pockets, which may not be available in all sites.
Innovation Solution
A construction arrangement featuring a hoistway with horizontal openings and a hoisting arrangement that includes a support structure with anchoring beams and flexible tension members, allowing for easy installation, safe operation, and relocation of heavy loads by distributing the load through flexible members, and enabling remote control of the hoisting device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a temporary hoisting arrangement is installed inside the hoistway using prior art methods, then hoisting of loads can be performed independently of building cranes, but the installation and dismantling process becomes difficult and time-consuming
Solution Approach 1:
The hoisting arrangement is divided into separate modular components: a support structure with support beams that can be independently positioned, a hoisting machine, and a platform. These segmented components can be installed separately and assembled quickly, eliminating the need for complex integrated installation procedures and reducing overall installation time.
Solution Approach 2:
The support structure is designed to be dynamically repositionable within the hoistway. The support beams can be moved to different locations and heights, allowing the hoisting arrangement to be quickly reinstalled at various positions without requiring complete dismantling and reinstallation of fixed structures.
2Reliability
If support structures like guide rails or pockets are built into the hoistway to provide support points, then reliable support for hoisting is achieved, but the device complexity and construction requirements increase
Solution Approach 1:
The support beams themselves serve as the support structure without requiring additional guide rails, pockets, or specialized hoistway modifications. The beams are designed to support the hoisting machine and platform directly, making the system self-sufficient and eliminating the need for complex pre-installed support infrastructure.
Solution Approach 2:
The support beams are designed as universal components that can function in multiple roles: providing structural support, serving as mounting points for the hoisting machine, and enabling platform positioning. This multi-functionality eliminates the need for separate specialized support structures like guide rails or pockets.
3Productivity
If the hoisting arrangement needs to be repositioned to higher positions in the hoistway, then construction work can progress, but the position changes become difficult and time-consuming
Solution Approach 1:
The support structure is designed with dynamic repositioning capabilities, allowing the support beams to be moved to different heights and locations within the hoistway. This dynamic design enables quick adjustment of the hoisting arrangement to higher positions as construction progresses, without requiring complex dismantling and reinstallation procedures.
Solution Approach 2:
The support beams are designed to be pre-positioned at various heights during installation, allowing the hoisting arrangement to be quickly repositioned to higher levels. The modular design enables preliminary placement of support elements that can be easily activated at different construction stages, reducing repositioning time.
4Loss of time
If a hoisting arrangement is installed before the ceiling is ready to be used as a supporting structure, then hoisting work can begin earlier, but finding reliable support points becomes difficult
Solution Approach 1:
The support structure is extracted from the ceiling and implemented as independent support beams that can be installed separately from the ceiling construction. This allows the hoisting arrangement to be installed and operational before the ceiling is complete, while maintaining reliable support through the standalone beam structure.
Solution Approach 2:
The support beams serve as an intermediary structure between the hoisting arrangement and the building structure. They provide reliable support points for early hoisting operations without requiring the ceiling to be complete, acting as a temporary but robust mediation structure that can be installed independently.
