Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighting systems struggle to provide clear communication quality feedback for individual lighting devices during installation, making it difficult for installers to determine the reliability of wireless communication and take necessary countermeasures.
Innovation Solution
A lighting device with a communication unit, command receiver, and light emitter that tests wireless communication based on received commands and provides visual feedback through flashing, dimming, or toning based on communication reliability information, allowing installers to assess and address communication issues directly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If collective testing of all lighting devices is performed, then the testing process is simplified, but the installer cannot determine the communication quality of individual devices
Solution Approach 1:
The patent divides the collective testing process into individual device testing. Each lighting device performs communication quality testing independently with its paired wireless device, and displays individual results through light emission patterns. This segmentation allows installers to see specific communication quality for each device while maintaining a systematic testing approach.
Solution Approach 2:
The patent implements feedback mechanisms where each lighting device provides visual feedback about its communication quality through specific light emission patterns (flashing, dimming, toning). This feedback loop allows installers to immediately see the communication status of individual devices, enabling informed decision-making about installation quality and necessary countermeasures.
2Loss of information
If individual device communication quality is displayed, then installer awareness of communication status is improved, but the installation process becomes more complex
Solution Approach 1:
The lighting devices perform self-testing of communication quality with their paired wireless devices. Each device automatically evaluates its own communication status and displays the results through light emission patterns. This self-service approach reduces the need for complex external testing equipment and simplifies the installation process while providing detailed communication quality information.
Solution Approach 2:
The patent uses different light emission patterns (flashing, dimming, toning) to represent different communication quality levels. This visual coding system allows installers to quickly understand communication status without complex displays or interfaces, maintaining simplicity while conveying detailed information about individual device communication quality.
3Reliability
If communication reliability information is provided for each device, then installer confidence in installation quality is increased, but the time required for installation increases
Solution Approach 1:
The patent performs communication quality testing during the pairing process itself, before the installation is considered complete. By conducting the testing as a preliminary action during device pairing, the system ensures communication reliability is verified early, allowing installers to address any issues immediately while minimizing additional time requirements.
Solution Approach 2:
The patent uses different light emission parameters (flashing frequency, dimming level, toning pattern) to encode communication reliability information. This efficient use of existing light emission capabilities allows detailed communication quality feedback to be provided without adding complex measurement or display equipment, thereby minimizing time consumption during installation.
Data Source
AI summary
A lighting device includes: a communication unit configured to wirelessly communicate with a wireless device provided externally; a command receiver that receives a command from outside; a light emitter including a light source; and a controller connected to the communication unit, the command receiver, and the light emitter. The command receiver receives a wireless device specifying command that specifies the wireless device with which the communication unit is to wirelessly communicate. The controller tests wireless communication with the wireless device via the communication unit based on the wireless device specifying command received, obtains communication reliability information regarding the reliability of the wireless communication, and causes the light emitter to perform at least one of flashing, dimming, and toning based on the communication reliability information obtained.
