Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional intelligent lighting systems face communication delays and overloads in wireless multi-node networks, leading to unreliable light adjustments, especially as the number of nodes increases, due to sub-optimal message routing and interference from other wireless technologies.
Innovation Solution
The system configures wireless communication routes between lighting nodes based on their geographical positions, using information about node locations and infrastructural layouts to minimize hops and reduce network traffic, allowing for direct or near-direct communication between adjacent nodes, and switches between unicast and broadcast modes to optimize message delivery.

Engineering Contradiction Analysis
1Adaptability or versatility
If wireless communication is used between lighting nodes to enable coordination and control, then the system achieves intelligent lighting control and coordination between lights, but the number of messages sent between nodes increases significantly, leading to network overload and communication delays
Solution Approach 1:
The patent segments the wireless network into multiple communication channels or groups, dividing the network traffic into smaller manageable segments. This reduces the load on individual communication paths and prevents network overload, thereby maintaining communication reliability while preserving coordination capabilities between lighting nodes.
Solution Approach 2:
The patent introduces intermediary devices or gateway nodes that mediate communication between lighting nodes. These intermediaries aggregate, filter, or route messages efficiently, reducing the total number of direct communications between nodes and preventing network overload while maintaining system-wide coordination.
2Area of stationary object
If the number of lighting nodes in the wireless network increases to cover larger areas, then the system coverage and illumination capability improve, but message delivery delays increase and messages may be lost
Solution Approach 1:
The patent organizes lighting nodes into hierarchical groups or zones, adding a spatial dimension to the network structure. This dimensional organization allows messages to be routed through zone gateways rather than requiring direct node-to-node communication across the entire network, reducing delivery delays while maintaining extensive coverage.
Solution Approach 2:
The patent pre-configures routing paths and establishes communication routes before messages need to be transmitted. By preparing forwarding relationships in advance based on the hierarchical structure, the system minimizes real-time routing decisions and reduces message delivery delays even as network size increases.
3Ease of manufacture
If conventional routing methods are used in wireless lighting networks, then the system is simple to implement, but network traffic becomes excessive and communication becomes unreliable
Solution Approach 1:
The patent changes the routing parameters from flat, equal-weight routing to hierarchical, position-aware routing. By incorporating spatial information and node hierarchy into routing decisions, the system optimizes message paths to reduce network traffic while maintaining implementation feasibility through standardized protocols and pre-configured structures.
