Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional IoT systems face challenges in connecting and controlling devices from different manufacturers due to the need for multiple protocol controllers, increased power consumption, and security concerns when devices are directly connected to the internet, as well as the lack of interoperability between devices controlled by different apps.
Innovation Solution
A cloud-based control system utilizing a universal bridge that operates across multiple communication protocols, connecting IoT devices to a cloud server and allowing centralized control, reducing the need for local control and enhancing security by communicating only through the bridge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple protocol controllers are added to support different communication protocols, then device compatibility and interoperability are improved, but device complexity and capital costs increase
Solution Approach 1:
The patent introduces a cloud-based gateway server as an intermediary that handles protocol translation and conversion. Instead of equipping each IoT device with multiple protocol controllers, the gateway server acts as a central mediator that receives data from devices using different protocols and translates it into a unified format for cloud processing, thereby reducing device complexity while maintaining compatibility
Solution Approach 2:
The gateway server is designed with multi-functional capabilities to handle multiple communication protocols simultaneously. It can translate between various protocols (Bluetooth, Wi-Fi, Zigbee, etc.) and the cloud platform's native protocol, making the system universally compatible with diverse IoT devices without requiring each device to support all protocols
2Adaptability or versatility
If multiple protocol controllers are added to support different communication protocols, then device compatibility is improved, but power consumption increases
Solution Approach 1:
The gateway server serves as an external intermediary that handles the computationally intensive protocol translation tasks. IoT devices only need to implement their native protocol and communicate with the gateway, which performs the complex multi-protocol translation in the cloud, thereby minimizing the power consumption requirements at the device level
Solution Approach 2:
The patent replaces the mechanical approach of adding physical protocol controller hardware to each device with a cloud-based software solution. The protocol translation functionality is migrated from device hardware to remote server infrastructure, reducing the energy footprint of individual devices while maintaining protocol conversion capabilities
3Ease of operation
If IoT devices are connected directly to the Internet, then connectivity and accessibility are improved, but security risks and system complexity increase
Solution Approach 1:
The gateway server acts as a security intermediary between IoT devices and the Internet. Devices connect to the gateway using their native protocols in a controlled environment, and the gateway handles all Internet communications, authentication, and data validation. This architecture allows devices to be Internet-accessible through the gateway while isolating them from direct Internet exposure and associated security threats
Solution Approach 2:
The system is segmented into distinct layers: the device layer (IoT devices using native protocols), the gateway layer (protocol translation and security processing), and the cloud layer (data processing and Internet connectivity). This segmentation allows security measures to be concentrated at the gateway layer, protecting individual devices from direct Internet threats while maintaining overall system connectivity
