Wireless Hoist Elevator Calling for Automated Floor Requests
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hoist elevators at construction sites require manual operation and communication methods like yelling or walkie-talkies, which are inefficient and lack a standardized, automated system for calling and responding to elevator requests.
Innovation Solution
A wireless hoist elevator operation system with floor call stations, car controllers, and operator panels that use RF and LoRa technologies for communication, enabling automated call transmission, display of call messages, and cancellation upon arrival.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual operation and communication methods (yelling or walkie-talkies) are used for hoist elevators, then the system is simple to implement, but the operational efficiency and standardization are poor
Solution Approach 1:
The patent replaces manual mechanical communication methods (yelling, walkie-talkies) with an automated electronic communication system. Floor call stations transmit signals electronically to car controllers, which then communicate with operator panels, eliminating the need for human vocal communication and manual coordination.
Solution Approach 2:
The system enables automatic call transmission and response without requiring manual intervention. When a user activates a floor call button, the system automatically transmits the call signal, routes it to the appropriate car controller, and notifies the operator panel, allowing the system to service itself without continuous human operation.
2Ease of operation
If automated wireless communication systems are implemented, then the operational efficiency and standardization improve, but the device complexity increases
Solution Approach 1:
The patent divides the hoist elevator communication system into distinct functional modules: floor call stations for initiating calls, car controllers for receiving and processing signals, and operator panels for displaying information and enabling response. Each module operates independently but communicates through standardized wireless protocols, making the overall system easier to manage despite its complexity.
Solution Approach 2:
The car controller serves multiple functions: receiving floor call messages from various floor call stations, transmitting signals to multiple operator panels, and managing communication across the entire hoist elevator system. This multi-functionality reduces the need for separate dedicated components for each function.
