Dual Elevator Control for Construction Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for managing the flow of people and goods within a building under construction are inefficient and lack optimization, failing to ensure smooth transition to the building's final transportation needs.
Innovation Solution
A method and elevator arrangement featuring dual elevator control systems for automatic movement of passenger and goods elevators, with the passenger elevator having an interior and automatic doors, and the goods elevator using a transport platform, allowing for efficient and safe transport between floors, and the option to transform the goods elevator into a passenger elevator using its components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If separate passenger and goods elevators are provided with automatic control systems, then transportation efficiency and safety are improved, but device complexity increases
Solution Approach 1:
The elevator system is designed with dual functionality where a single elevator infrastructure serves both passenger and goods transportation purposes. The control system can operate in different modes (passenger mode and goods mode) by receiving different signal types, allowing one system to perform multiple functions without requiring completely separate elevator installations for each purpose.
Solution Approach 2:
A centralized control system acts as an intermediary between signal sources (passenger signals and goods signals) and the elevator cars. This control system processes different types of signals and coordinates the operation of elevator cars accordingly, managing the complexity centrally rather than requiring separate control systems for each elevator function.
2Adaptability or versatility
If goods elevator is transformed into passenger elevator, then adaptability to final building needs is improved, but manufacturing complexity increases
Solution Approach 1:
The elevator system is designed with dynamic reconfigurability, allowing the goods elevator to be transformed into a passenger elevator when needed. The control system can switch between different operational modes and signal types, enabling the same physical infrastructure to adapt to changing building needs without requiring complete reconstruction.
Solution Approach 2:
The transformation from goods elevator to passenger elevator is achieved by changing operational parameters rather than physical structure. The control system accepts different signal types (passenger signals versus goods signals) and adjusts its operation accordingly, allowing the same elevator car and infrastructure to serve different purposes through parameter changes alone.
3Reliability
If automatic door and interior are provided in passenger elevator, then passenger safety and comfort are improved, but device complexity increases
Solution Approach 1:
The elevator car is designed with universal features that serve both passenger and goods transportation. The automatic door and interior structure are provided in the elevator infrastructure, and the control system determines their usage based on the type of operation (passenger or goods mode), allowing these features to benefit both functions without requiring separate elevator systems.
