Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting systems require all fixtures to be of the same type for master-slave configurations, limiting flexibility and compatibility in creating coordinated light shows.
Innovation Solution
A portable multi-function lighting device with a built-in digital controller that can wirelessly connect and control multiple types of lighting fixtures and accessories in a master-slave configuration without cables or wireless DMX, using a wireless control module to synchronize different types of lighting devices into an integrated system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional master-slave lighting systems are used, then control coordination is achieved, but all fixtures must be of the same type which limits flexibility and compatibility
Solution Approach 1:
The master controller is designed with universal compatibility to control multiple types of lighting fixtures (PAR cans, spotlights, wash lights, moving heads) through a unified wireless interface. The system performs multiple functions by supporting both traditional DMX control and proprietary wireless protocols, allowing one controller to manage diverse fixture types without requiring separate control systems for each fixture category.
Solution Approach 2:
The patent replaces the mechanical cable-based DMX connection system with a wireless communication system. Instead of physically connecting fixtures through DMX cables in a daisy-chain configuration, the master controller transmits control signals wirelessly to slave fixtures, eliminating the need for physical infrastructure while maintaining control coordination.
2Ease of operation
If wireless control is implemented, then cable connections are eliminated, but compatibility with existing DMX-based fixtures is reduced
Solution Approach 1:
The master controller acts as an intermediary device that bridges wireless and DMX protocols. It receives control inputs through wireless communication and can translate or coordinate these signals to control both wireless-capable fixtures and traditional DMX-based fixtures. This intermediary function allows the system to support multiple protocols simultaneously without requiring all fixtures to speak the same language.
Solution Approach 2:
The control system is designed with multi-protocol support, enabling the master controller to communicate through both wireless interfaces and traditional DMX connections. This universality allows integration of fixtures from different eras and technologies, maintaining backward compatibility while enabling modern wireless functionality.
3Adaptability or versatility
If multiple different types of fixtures are controlled, then lighting design flexibility increases, but synchronization coordination becomes more difficult
Solution Approach 1:
The wireless communication system implements feedback mechanisms where slave fixtures report their status, position, and operational state back to the master controller in real-time. This feedback loop allows the master to adjust control signals dynamically to maintain synchronization across diverse fixture types, compensating for variations in response times and capabilities through continuous monitoring and adjustment.
Solution Approach 2:
The control system employs dynamic parameter adjustment to accommodate different fixture types. Instead of using fixed control parameters for all fixtures, the system adapts timing, intensity, and sequence parameters based on the specific characteristics of each slave fixture, enabling synchronized operation across diverse equipment while maintaining reliability.

AI summary
A portable multi-function lighting device is provided that includes a built-in digital controller configured to be connected wirelessly with one or more other lighting fixtures in a master-slave relationship in order to perform a coordinated light show. The portable multi-function lighting system is configured with a plurality of different types of lighting fixtures for performing different types of effects. The portable multi-function lighting device wirelessly transmits control signals to other fixtures that include a lighting effect or a theatrical or special effect, which fixtures are external to, i.e., not part of, the portable multi-function lighting device to coordinate a show in which like types of effects of the separate fixtures and of the portable multi-function lighting device are coordinated with one another.
