Stage Light Command Arbitration for Integrated Graphic Effects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current stage lighting technologies cannot simultaneously manage external graphic effects and basic parameters of stage light fixtures, limiting the creation of innovative effects due to an 'exclusive' approach that restricts the integration of internal and external graphic commands.
Innovation Solution
A stage light fixture with a control device, graphic module, and input management module that processes concurrent commands from different sources, prioritizing and integrating local, external, and adjusting commands to control source assemblies for creating integrated graphic patterns and effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the stage light fixture uses an exclusive approach to manage either basic parameters/internal graphic effects or external graphic effects, then the control system remains simple, but the amount of stage effects obtainable is significantly limited
Solution Approach 1:
The patent merges multiple command management functions into a unified control system. The input management module combines external graphic effect commands, internal graphic effect commands, and basic parameter adjustment commands into a single command sequence that can be processed simultaneously, eliminating the need for exclusive mode switching and enabling versatile stage effects without proportionally increasing control system complexity
Solution Approach 2:
The control device is designed with multi-functionality to handle diverse command types through a universal interface. It can process external graphic effect commands (pixel mapping), internal graphic effect commands (embedded animations), and basic parameter adjustments (intensity, color, position) through the same command bus and processing logic, allowing the system to adapt to multiple operational modes without requiring separate control systems for each function
2Adaptability or versatility
If the stage light fixture integrates multiple command sources (external graphic effects, internal graphic effects, and basic parameter adjustments), then creative freedom increases, but command management complexity increases
Solution Approach 1:
The input management module serves as an intermediary between multiple command sources and the control device. It receives commands from external graphic effect systems, internal graphic effect memory, and basic parameter controls, arbitrates between concurrent commands using priority rules, and outputs a unified command sequence. This mediator simplifies operation by automatically resolving command conflicts without requiring manual intervention from the operator
Solution Approach 2:
The system changes the parameter of command priority levels dynamically based on command type and operational context. External graphic effect commands may be assigned higher priority during pixel mapping operations, while internal graphic effects may take precedence during embedded animation modes. This dynamic parameter adjustment allows creative freedom through multiple command sources while maintaining ease of operation through automated priority management
