Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elevator systems with destination control and direct call options are time-consuming and not user-friendly, often resulting in incorrect inputs due to manual programming methods, especially when using ID cards or RFID tags.
Innovation Solution
An elevator system with a destination control system that recognizes signal patterns produced by moving identification devices, allowing for different programs to be activated based on these patterns, using input devices that can read electronically readable cards, RFID tags, or biometric data, and provide feedback through displays, to efficiently allocate elevator car movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual programming method is used for direct call option, then the system provides destination selection capability, but the operation becomes time-consuming and error-prone
Solution Approach 1:
The patent replaces the mechanical/manual programming method with an automatic recognition system using optical or electromagnetic scanning of identification devices. The system automatically captures destination information from the ID device without requiring manual floor-by-floor counting or programming, thus eliminating time consumption while maintaining ease of operation.
Solution Approach 2:
The system enables self-service by allowing the identification device itself to carry and transmit the destination information. The passenger simply presents their ID device, and the system automatically reads and processes the destination data embedded in the device, eliminating the need for manual intervention or time-consuming programming steps.
2Reliability
If manual programming method is used for direct call option, then the system provides destination selection capability, but incorrect inputs are produced due to user error
Solution Approach 1:
The patent replaces manual programming with automatic optical or electromagnetic recognition of the identification device. The system reads destination information directly from the ID device's stored data, eliminating human error in floor selection or programming. This substitution ensures high reliability and accuracy of destination input while maintaining simplicity for the user.
Solution Approach 2:
The system incorporates feedback mechanisms where the call panel displays or reads the respective floor number during the scanning process, allowing the system to verify and confirm the detected destination information. This feedback loop ensures that the correct destination is captured from the identification device, preventing incorrect inputs while keeping the operation simple for passengers.
3Productivity
If destination control system is implemented, then elevator allocation is optimized, but the system complexity increases due to programming requirements
Solution Approach 1:
The patent replaces complex manual programming interfaces with automatic recognition technology that reads destination information directly from identification devices. This substitution simplifies the user interface and operational complexity while maintaining the optimized elevator allocation functionality of the destination control system. The system automatically processes the scanned data to allocate elevators efficiently.
Solution Approach 2:
The identification devices pre-store destination information before the passenger arrives at the elevator. This preliminary action eliminates the need for complex real-time programming or selection processes. When the passenger presents the ID device, the system already has the destination data ready, simplifying the interaction while enabling efficient elevator allocation based on pre-determined destinations.
