Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting control systems face challenges in efficiently connecting and controlling multiple lighting devices via wireless mesh networks due to high connection failure rates and increased delay times, especially as the number of devices increases, leading to user dissatisfaction and degraded system efficiency.
Innovation Solution
A method utilizing a mobile communication terminal with a lighting control application to select and designate a lighting device with the strongest signal as a bridge, register other devices as a mesh network group, and manage their operations, thereby minimizing bridge connection delays and maximizing connection success rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a lighting controller selects a bridge device from multiple lighting devices to establish wireless mesh network connection, then the system can control multiple lighting devices, but the connection failure rate increases and delay time increases as the number of lighting devices increases
Solution Approach 1:
The patent introduces a mobile communication terminal as an intermediary device between the lighting controller and the lighting devices. The terminal receives connection responses from multiple lighting devices simultaneously and transmits them to the controller, enabling the controller to select an optimal bridge device without directly handling multiple concurrent connections. This intermediary role resolves the contradiction by allowing the system to scale to more devices while maintaining connection reliability through centralized response management.
2Reliability
If the lighting controller confirms connection by receiving connection response from bridge device, then the connection can be established, but the delay time increases due to repeated connection requests
Solution Approach 1:
The mobile communication terminal performs preliminary actions by receiving and buffering connection responses from multiple lighting devices before the controller needs to make its selection. The terminal prepares the connection information in advance, so when the controller requests connection confirmation, the data is already available, eliminating the need for repeated connection requests and reducing delay time while maintaining reliable connection establishment.
3Area of stationary object
If multiple lighting devices are connected to wireless mesh network, then the system provides comprehensive lighting control coverage, but the frequency resource limitation causes higher connection failure rate
Solution Approach 1:
The mobile communication terminal acts as a frequency resource manager and intermediary, coordinating communication between the controller and multiple lighting devices. It receives connection responses from multiple devices using available frequency resources efficiently and manages the transmission to the controller, allowing the system to maintain comprehensive coverage with multiple devices while preventing connection failures through centralized resource management.
