Solution Overview
Problem
Existing lighting systems that use different communication protocols for local and remote networks are forced to communicate via the internet, leading to delayed communication due to the need for protocol conversion, which hampers speed and efficiency.
Innovation Solution
A communications device with a single semiconductor integrated circuit that includes two processors, one for each protocol, allowing seamless switching between ZigBee and Bluetooth protocols to enable direct communication between local networks without internet reliance, using a controller to manage the protocol switching and ensure efficient data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If local and remote lighting systems use different communication protocols, then each system can operate with its own optimized protocol, but communication between systems is forced through the internet causing delays
Solution Approach 1:
The gateway device acts as an intermediary between the first local network (using first communication protocol) and the second local network (using second communication protocol). It receives information from one network, translates it to the other protocol, and transmits it to the target network, enabling direct communication without internet dependency and reducing communication delay.
Solution Approach 2:
The gateway device is designed with dual communication protocol support, allowing it to function with both first and second communication protocols. This multi-functionality enables it to bridge different local networks using different protocols directly, eliminating the need for internet-based communication and reducing latency.
2Adaptability or versatility
If internet-based communication is used for protocol conversion, then different protocols can be bridged, but communication speed decreases due to remote routing
Solution Approach 1:
The gateway device serves as a local intermediary that performs protocol translation between first and second communication protocols within the local network environment. This eliminates the need for remote internet-based translation, significantly improving communication speed while maintaining protocol adaptability.
Solution Approach 2:
The gateway device pre-establishes communication channels and protocol translation capabilities locally between the two networks. By having the translation infrastructure in place beforehand within the local network, communication can occur directly without waiting for internet-based translation, thus improving speed.
3Device complexity
If a single semiconductor integrated circuit is used with dual processors, then device complexity is reduced and cost is lowered, but managing multiple protocols increases control complexity
Solution Approach 1:
The gateway device combines two processors for different communication protocols into a single semiconductor integrated circuit. This merging approach reduces device structure complexity and cost while the controller manages protocol switching through integrated control logic that coordinates both processors efficiently.
Solution Approach 2:
The single semiconductor integrated circuit is designed with universal functionality to handle both first and second communication protocols through its dual processors. The controller manages this multi-functional capability by implementing protocol switching logic that seamlessly transitions between protocols, making the complexity management transparent to external systems.

AI summary
A communications device connects one or more first lighting devices included in a first local network with one or more second lighting devices included in a second local network different from the first local network. The communications device includes a single semiconductor integrated circuit including: a first processing unit that wirelessly communicates with the one or more first lighting devices via a first communications protocol; a second processing unit that wirelessly communicates with the one or more second lighting devices via a second communications protocol different from the first communications protocol; and a control unit that switches between causing the first processing unit to wirelessly communicate with the one or more first lighting devices and causing the second processing unit to wirelessly communicate with the one or more second lighting devices.
