USB Dongle Wireless DMX Transceiver Power and Mode Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless DMX signal transmission systems for lighting and effects equipment require separate power supplies, are limited to either receiving or transmitting, and still necessitate the use of cables to connect all fixtures, making them bulky, costly, and inefficient.
Innovation Solution
A wireless DMX transmission apparatus in the form of a USB dongle with control circuitry that can selectively receive or transmit DMX signals, powered by the connected DMX-enabled device, eliminating the need for a separate power supply and allowing for wireless communication between DMX devices, including the ability to set operating frequencies for multiple device connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If prior art wireless DMX devices are used, then wireless transmission capability is achieved, but additional power supply is required which increases size, weight and cost
Solution Approach 1:
The wireless DMX device draws power from the DMX fixture itself through the existing DMX cable connection, making the fixture serve its own power needs. This eliminates the requirement for a separate power supply unit, reducing device complexity while maintaining wireless transmission capability.
Solution Approach 2:
The existing DMX cable connection serves dual purposes: both power delivery and data transmission. By making the cable infrastructure multi-functional, the system eliminates the need for separate power wiring and power supply components, simplifying the overall device structure.
2Ease of operation
If prior art wireless DMX devices are used, then wireless signal reception is achieved, but cannot selectively transmit or receive
Solution Approach 1:
The device incorporates switches that allow dynamic reconfiguration of its operational mode. The system can transition between receiving mode, transmitting mode, or both simultaneously based on the position of the switches, providing adaptability while maintaining ease of wireless operation.
3Area of stationary object
If multiple devices are used for wireless transmission, then signal coverage is extended, but cables are still required to connect all fixtures
Solution Approach 1:
The wireless DMX device can function as either a receiver, a transmitter, or both simultaneously. This multi-functionality allows a single device to serve multiple fixtures, eliminating the need for additional cable connections to each fixture while extending signal coverage across the event venue.
