Solution Overview
Problem
Existing elevator control methods, such as touch-based controls, pose safety risks, especially during infectious disease outbreaks, due to the potential spread of pathogens through shared surfaces.
Innovation Solution
A non-contact elevator control system using speech recognition technology, where user instructions are converted into elevator control commands via a speech device, either directly or through a cloud-based system, to operate elevators without physical interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If touch-based elevator control is used, then ease of operation is maintained, but safety risk increases due to potential pathogen spread through shared surfaces
Solution Approach 1:
The patent replaces mechanical touch-based control with voice-based control. The speech device captures user commands through airborne sound waves and converts them to electronic signals, eliminating the need for physical contact with elevator buttons. This substitution of mechanical interaction with acoustic field interaction resolves the contradiction by maintaining operational convenience through natural voice commands while eliminating safety risks associated with touching shared surfaces.
Solution Approach 2:
The patent introduces a speech device as an intermediary between the user and the elevator control system. This intermediary captures voice commands, processes them through speech recognition, and transmits control signals to the elevator without requiring direct physical contact. The intermediary device acts as a buffer that decouples the user from potential contamination sources while maintaining full control functionality.
2Reliability
If speech recognition control is implemented, then safety is improved by eliminating physical contact, but device complexity increases due to additional speech processing components
Solution Approach 1:
The patent leverages the multi-functionality of modern speech devices that already possess microphones, processors, and communication capabilities for other purposes (such as smart speakers or mobile phones). By utilizing these existing universal devices for elevator control, the system adds minimal complexity while achieving contactless operation. The speech device's existing architecture handles voice capture, recognition, and signal transmission, reducing the need for dedicated specialized components.
3Measurement precision
If cloud-based speech recognition is used, then recognition accuracy is improved, but communication time delay increases
Solution Approach 1:
The patent implements preliminary action by pre-processing and pre-recognition of voice commands locally on the speech device before transmission to the cloud. The device captures and初步 processes the voice signal, filtering out background noise and identifying key command elements in advance. This preliminary local processing reduces the amount of data that needs to be transmitted to the cloud and enables faster initial response, mitigating the time delay inherent in cloud-based recognition while maintaining high accuracy through subsequent cloud verification.
