Construction Elevator with Vertical and Horizontal Door Configurations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for transporting goods and people during building construction are inefficient and do not smoothly transition to the final building configuration, lacking in efficiency and adaptability.
Innovation Solution
A construction-time elevator arrangement with a hoistway and vertically displaced landings, featuring a first door with a vertical opening for goods transport and a second door with a horizontal opening for passenger transport, allowing for easy conversion between goods and passenger transport using the same elevator car and control system, facilitating efficient and safe movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a temporary elevator installed outside the building or crane/hoist is used for goods transport during construction, then goods can be transported vertically, but the flow of goods is not sufficiently efficient and transition to final building configuration is not smooth
Solution Approach 1:
The elevator car is designed to serve dual purposes: during construction phase it transports goods with vertical door opening, and after construction it transports passengers with horizontal door opening. The same hoistway and elevator infrastructure is used for both phases, eliminating the need for separate temporary and permanent elevator systems.
Solution Approach 2:
The door opening direction is made changeable - the elevator car can operate with vertical door opening during construction and switch to horizontal door opening for passenger transport in the final building. This dynamic adaptability allows the same physical infrastructure to serve different functional requirements at different time phases.
2Ease of operation
If a construction-time elevator installed inside the building is used, then vertical transport is enabled, but it does not ensure sufficiently smooth transition to serving transportation needs of the final building
Solution Approach 1:
The elevator system is designed as a universal infrastructure that serves both construction-phase goods transport and post-construction passenger transport. The same hoistway, elevator car, and control system are used for both phases, ensuring smooth transition without requiring separate elevator installations.
Solution Approach 2:
The door configuration parameter is changed between phases - vertical door opening for construction goods transport, and horizontal door opening for final building passenger transport. This parameter change allows the same physical elevator infrastructure to adapt to different operational requirements.
3Ease of manufacture
If vertical opening door is used during construction, then installation and modification is easy, but it is not optimized for final building passenger transport needs
Solution Approach 1:
The door opening direction is made dynamic and changeable between phases. During construction, vertical door opening facilitates easy installation and goods transport. After construction, the system switches to horizontal door opening which is optimized for passenger entry and exit efficiency in the final building.
Solution Approach 2:
The hoistway is preliminarily constructed with openings that can accommodate both vertical and horizontal door configurations. The infrastructure is prepared in advance to support both construction-phase and final-building operational requirements.
4Ease of operation
If horizontal opening door is used for final building, then passenger transport is optimized, but it is not suitable for construction-time goods transport needs
Solution Approach 1:
The door system is made dynamic, capable of changing opening direction based on operational phase. Horizontal door opening optimizes passenger transport in the final building, while vertical door opening optimizes goods transport during construction. The same physical infrastructure supports both configurations.
Solution Approach 2:
The door system is segmented into configurable components that can be arranged in different configurations - vertical opening for construction phase and horizontal opening for final building phase. This segmentation allows flexible adaptation to different operational requirements.
