Projector-Mediated Lamp Pairing for Cross-Protocol Light Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing illumination control systems fail to effectively control light emitting devices when they do not conform to the same control protocol standard as the control device.
Innovation Solution
A method involving pairing an information processing device with a display device, reading an identification code on a lamp, transmitting this code to the display device, and using the display device to pair with the lamp, allowing control signals to be transmitted between the information processing device and the lamp even if they do not share a common control protocol.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If direct control protocol matching is used between control device and light emitting device, then control reliability is improved, but device compatibility deteriorates
Solution Approach 1:
The patent introduces a display device as an intermediary between the information processing device and the light emitting device. The display device receives control instructions from the information processing device, obtains corresponding control codes, and transmits them to the light emitting device. This mediator enables control across different protocol standards without requiring direct protocol matching between the control and light emitting devices.
2Adaptability or versatility
If intermediary device is introduced for cross-protocol control, then device compatibility is improved, but system complexity increases
Solution Approach 1:
The display device performs multiple functions: it serves as both a display device and a protocol conversion intermediary. By utilizing an existing device (display device) for dual purposes, the system avoids adding dedicated conversion hardware, thereby reducing overall system complexity while maintaining compatibility across different control protocols.
