Spotlight Control via Unique Light Signal Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for controlling multiple spotlights, such as adjusting light intensity, color, and beam direction, are inconvenient and non-intuitive, especially when trying to change settings while under the spotlights, as they often require connecting all devices to a central point for control.
Innovation Solution
Each spotlight radiates a unique light signal that is detected by a remote control with a sensor, allowing it to send a combined identifying and control signal to associated control units, which adjust the settings accordingly, enabling intuitive and convenient control through a remote interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If all lighting devices are connected to a central point for control, then control capability is achieved, but convenience and intuitiveness deteriorate
Solution Approach 1:
The patent replaces the mechanical/wired central control system with an optical wireless communication system. The remote control uses optical sensors to detect unique light signals from each spotlight and transmits control signals wirelessly, eliminating the need for physical connections to a central control point while maintaining full control capability.
Solution Approach 2:
The patent introduces optical signals as an intermediary medium between the user and the lighting devices. The remote control detects unique light signals from spotlights and uses these as identifiers to send control commands, allowing control without direct physical connection to each device.
2Measurement precision
If multiple spotlights are controlled individually, then control precision is improved, but ease of operation deteriorates
Solution Approach 1:
The patent assigns a unique light signal with specific characteristics (color, intensity, pattern) to each spotlight, creating locally distinguishable identifiers. This allows the remote control to precisely identify and target specific spotlights for control while maintaining simple operation through intuitive optical detection.
3Stability of the object's composition
If control is performed from a central point, then system coordination is improved, but intuitiveness deteriorates
Solution Approach 1:
The system uses the unique light signals emitted by each spotlight as feedback identifiers. The remote control detects these signals and uses them to automatically identify the target spotlight for control, creating an intuitive feedback loop that maintains system coordination while improving user experience.
