Solution Overview
Problem
Current indoor wireless communication technologies face challenges in providing high-security, high-reliability, and low-cost solutions for dense device connectivity, particularly in indoor environments, due to high power consumption, channel interference, and limited transmission distances, which complicates the implementation of the Internet of Things (IoT) systems.
Innovation Solution
An indoor wireless communication network is established by integrating wireless communication modules into LED lighting devices, which serve as both network nodes and access points, utilizing adaptive power supplies and multiple communication protocols, and connecting to a cloud computing platform for secure and efficient data management, allowing for self-organized network topologies and seamless integration with existing infrastructure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If WiFi technology is used for indoor wireless communication, then network coverage and data transmission capability are improved, but power consumption increases significantly
Solution Approach 1:
The system segments the network into multiple protocols (WiFi for high-bandwidth applications, Bluetooth Low Energy for low-power sensor communication, Zigbee for mesh networking). Each protocol handles specific communication tasks, allowing devices to select the most energy-efficient protocol for their particular needs rather than relying solely on power-consuming WiFi.
Solution Approach 2:
The patent implements a multi-protocol communication module that provides universal compatibility across different wireless standards. This allows a single device to function across multiple network types, enabling low-power communication modes when high bandwidth is not required, thus reducing overall power consumption while maintaining reliable network coverage.
2Use of energy by moving object
If Bluetooth and Zigbee technologies are used to extend transmission distance, then power consumption is reduced, but transmission distance remains limited requiring large-scale deployment of receiver terminals
Solution Approach 1:
The patent implements a hierarchical network architecture where Bluetooth Low Energy devices serve as remote wake-up triggers nested within a larger WiFi or cellular network structure. The BLE device can be placed far from the main system, providing long-range detection capability, while actual data transmission occurs through the longer-range WiFi or cellular connection to the cloud platform, effectively extending functional distance without requiring numerous intermediate receivers.
Solution Approach 2:
The system introduces a cloud platform as an intermediary that receives data from remote BLE devices and relays it to the main control system. This mediator enables communication over extended distances by using the cloud infrastructure to bridge the gap between geographically dispersed devices, eliminating the need for dense local receiver deployment.
3Adaptability or versatility
If multiple operators provide WiFi access service simultaneously in public places, then network availability is improved, but channel interference increases
Solution Approach 1:
The patent implements dynamic parameter adjustment where communication modules automatically adapt transmission parameters (frequency, power, protocol selection) based on detected environmental conditions. When multiple WiFi networks are detected causing interference, the system switches to alternative protocols or adjusts transmission parameters to avoid congested channels, maintaining network availability while minimizing interference impact.
4Reliability
If receiver terminal devices are deployed on large scale to compensate for limited transmission distance, then communication coverage is improved, but installation cost increases considerably
Solution Approach 1:
The patent implements a nested architecture where low-cost Bluetooth Low Energy devices are nested within the existing lighting infrastructure or placed strategically, providing long-range detection. These nested BLE devices trigger wake-up signals to main processing units only when needed, extending effective coverage without requiring dense deployment of full-featured receiver terminals, thus reducing installation costs while maintaining communication reliability.
