Offline Computer for Stage Lighting Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Stage lighting devices are often unpowered and disconnected, making maintenance and software updates difficult, as they can only be tested and accessed when powered and connected, which is typically during a light show or installation, making it inconvenient for maintenance operations.
Innovation Solution
A Global Assist Package with a processing device, battery, and cellular communicator that allows communication and operation independently of the stage lighting device, enabling maintenance, software updates, and configuration even when the device is unpowered, using local Ethernet, wireless Ethernet, or cellular networks, and allowing pre-configuration of settings and software updates before power-up.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If stage lighting devices are connected to local networks for maintenance and testing, then accessibility for maintenance is improved, but the devices must be powered and installed which increases labor intensity and time consumption
Solution Approach 1:
The patent enables preliminary testing, software updates, and configuration of stage lighting devices before they are installed and powered up. The offline computer can communicate with devices through stored communication addresses, allowing all maintenance operations to be completed in advance during manufacturing or storage, eliminating the need to wait for installation and power-up time
2Reliability
If stage lighting devices are tested only when powered and installed, then accurate testing is achieved, but the labor intensity and complexity of maintenance operations increase
Solution Approach 1:
The patent extracts the testing and maintenance operations from the installation context. By storing communication addresses and enabling offline communication, the testing function is separated from the power-up and installation requirements, allowing devices to be tested in any state without requiring complex installation procedures
3Productivity
If stage lighting devices remain unpowered and unconnected during storage, then storage efficiency is improved, but the ability to update software and test devices is lost
Solution Approach 1:
The patent enables software updates and configuration changes to be performed in advance while devices are in storage and unpowered. By storing communication addresses and enabling offline computer access, all software updates can be completed before devices are deployed, maintaining storage efficiency while adding update capability

AI summary
A lighting device or lighting associated device which includes an off-line computer in addition to the controlling computer. The off-line computer is one that uses less power, but is accessible wirelessly even when the light is off-line and not receiving power. The off-line computer can be used to update the program and/or media that is stored in the lighting device.
