Parallel Elevator Component Transport and Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for elevator component installation are inefficient due to sequential transportation and installation of guide rails and landing entrance components, limiting the size and weight of materials that can be transported and requiring stationary installation, which slows down the process and increases idle time for tools and personnel.
Innovation Solution
A system with two independent working platform systems and two independent material hoisting systems allows for parallel transportation and installation of guide rails and landing entrance components, enabling simultaneous movement and installation of multiple guide rail sections and pre-assembled landing door arrangements, reducing the need for sequential installation and optimizing the use of hoisting systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single working platform is used for installing guide rails and transporting materials, then the installation process can be simplified, but the transportation of materials must be sequential and cannot occur while installation is in progress, reducing productivity
Solution Approach 1:
The system is divided into two independent working platforms: one dedicated to guide rail installation and another to material transportation. This segmentation allows both functions to operate simultaneously without interfering with each other, resolving the contradiction between process simplicity and installation speed.
Solution Approach 2:
Two previously separate functions (guide rail installation and material transportation) are merged into a single integrated system with two coordinated platforms. This allows both operations to occur in parallel within the same elevator shaft environment, improving productivity while maintaining manageable complexity through systematic coordination.
2Device complexity
If a single material hoisting system is used, then the system structure is simpler, but only one type of material can be transported at a time, increasing loss of time
Solution Approach 1:
The hoisting system is segmented into two independent subsystems: one for transporting guide rail sections and another for transporting landing entrance components. Each subsystem can operate independently and simultaneously, eliminating idle time while keeping each individual hoisting subsystem relatively simple.
Solution Approach 2:
Each hoisting system is designed to be specialized for its specific material type, allowing optimized transport mechanisms. The dual-hoisting system provides multi-functionality at the system level while maintaining simplicity at the component level, preventing time loss through parallel operations.
3Productivity
If the working platform carries large and heavy materials, then fewer trips are needed, but the platform size and carrying capacity are limited, restricting the ability to transport pre-assembled landing door arrangements
Solution Approach 1:
The loading capacity requirement is segmented between two platforms. The second platform is specifically designed with sufficient capacity to handle large pre-assembled landing door arrangements, while the first platform handles guide rails. This segmentation allows each platform to be optimized for its specific load type, increasing overall system adaptability without requiring either platform to be excessively large.
Solution Approach 2:
The solution moves from a single-platform dimensional constraint to a two-platform spatial arrangement. By utilizing the vertical and horizontal space in the elevator shaft more effectively with two platforms at different levels, the system can accommodate larger materials that would not fit on a single platform, thereby increasing adaptability while maintaining reasonable platform sizes.
4Device complexity
If materials are transported one-by-one in the elevator shaft, then the hoisting system can be simple, but the installation process becomes sequential and slower, reducing productivity
Solution Approach 1:
The transportation system is segmented into two parallel streams: one for guide rails and one for landing entrance components. Each stream uses a dedicated hoisting system that remains relatively simple, while the parallel operation of both streams collectively increases installation speed by eliminating sequential dependencies.
