Engineering Contradiction Analysis
1Productivity
If a single communication channel and protocol are used for elevator data transmission, then the system structure is simple, but the communication throughput and reliability are insufficient for high volume real-time data from multiple IoT devices
Solution Approach 1:
The communication system is segmented into multiple independent channels (first communication channel and second communication channel) with different protocols. Each channel handles specific data types or priority levels, allowing parallel data transmission and increasing overall throughput without requiring all data to traverse complex multi-protocol routing paths.
Solution Approach 2:
The gateway device is designed with multi-functionality to handle multiple communication protocols simultaneously (first protocol for the first channel, second protocol for the second channel). This universal gateway can adapt to different data formats and transmission requirements from various IoT devices, enabling efficient communication with diverse building systems without requiring separate dedicated systems for each protocol type.
2Adaptability or versatility
If multiple communication protocols are implemented to support various IoT devices, then the adaptability and compatibility improve, but the data transmission reliability and security become more difficult to ensure
Solution Approach 1:
Different communication protocols are segmented and assigned to different dedicated channels based on their reliability and security characteristics. Critical data requiring high reliability and security use the first communication channel with the first protocol, while less critical data use the second channel with the second protocol. This segmentation isolates protocol-specific vulnerabilities and ensures reliable transmission for essential communications.
Solution Approach 2:
The gateway acts as an intermediary that translates and manages communications between different protocols and devices. It receives data from various IoT devices using different protocols, processes and validates the data, and transmits it through the appropriate channel using the suitable protocol. This intermediary function maintains protocol compatibility while ensuring reliable and secure data transmission to the cloud or other systems.
3Adaptability or versatility
If real-time data from multiple IoT devices is collected and transmitted to cloud networks, then the building ecosystem becomes more connected and intelligent, but the data volume and processing complexity increase significantly
Solution Approach 1:
The data processing complexity is segmented by organizing data from different IoT devices into separate communication channels based on their importance and real-time requirements. Critical real-time data from safety and operational devices uses the first channel with prioritized processing, while less time-sensitive data from environmental sensors and building management devices uses the second channel. This segmentation allows the system to handle large volumes of data from multiple sources without overwhelming processing complexity.
Solution Approach 2:
The gateway serves as an intermediary that consolidates data from multiple IoT devices with different protocols and formats into standardized data structures suitable for cloud reception. It performs protocol translation, data validation, filtering, and formatting operations, reducing the complexity of processing diverse data streams. The gateway manages the complexity of connecting to multiple cloud networks and routing data appropriately, allowing the building ecosystem to remain highly connected while maintaining manageable processing complexity.

AI summary
An elevator system includes at least one autonomous unit for controlling an elevator and a multichannel-edge-gateway that builds communication between the autonomous unit and data resources on an IoT network. The multichannel-edge-gateway has more than one communication channel), wherein these communication channels provide data communicating using the same protocol or different protocols either synchronously or asynchronously. The multichannel-edge-gateway includes a channel assignment that automatically matches one of the communication channels to one of the protocols according to data to be sent from the multichannel-edge-gateway.
