Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing control systems for apparatuses in lighting, sound, video, and special effects engineering face limitations in data and current transfer due to the limited number of control channels in XLR connectors, especially when complex switchable apparatuses or a large number of devices are connected in series, leading to mechanical stress and potential damage from rough handling.
Innovation Solution
Implementing an ethernet device connector built-in module that provides power and data transfer through a single cable, using PoE or PoDL technology, with a distributor component on a printed circuit board to distribute signals and power to multiple apparatuses, allowing for complex control and integration of devices from different fields.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If XLR connectors are used for control and power supply in serially connected apparatuses, then the connection is standardized and mechanically robust, but the number of control channels is limited for complex devices or large numbers of apparatuses
Solution Approach 1:
The patent applies multi-functionality by enabling a single ethernet cable to perform multiple functions simultaneously: data transmission for controlling multiple apparatuses and power supply through PoE technology. This replaces the traditional separate DMX cables for control and power cables for供电, thereby increasing control channel capacity without proportionally increasing system complexity
Solution Approach 2:
The patent merges the control signal transmission and power supply functions into a single ethernet infrastructure. By combining data and power transfer through one cable type, the system achieves higher adaptability for complex devices while reducing the overall complexity of multiple separate connection systems
2Productivity
If multiple apparatuses are connected in a chain using conventional connectors, then the number of cables is reduced, but the connectors are exposed to significant mechanical loads and frequent plugging/unplugging
Solution Approach 1:
The ethernet connector performs dual functions of data transmission and power supply, eliminating the need for separate control and power connectors. This reduces the total number of connectors subject to mechanical stress and plugging/unplugging cycles, thereby improving both installation efficiency and connector durability
3Adaptability or versatility
If ethernet device connector built-in module is implemented, then data and power transfer capabilities are enhanced, but the device structure becomes more complex
Solution Approach 1:
The patent introduces an intermediary module that integrates the ethernet connector, distributor component, and power supply interface into a unified unit. This modular approach manages the complexity of enhanced data and power transfer capabilities by providing a pre-integrated solution that simplifies installation and reduces the burden on the end user

AI summary
An ethernet device connector built-in module for a controllable apparatus from lighting, sound, video or special effects engineering, for incorporating the apparatus in a chain of apparatuses serially connected by ethernet. The construction of the built-in module allows serial control of complexly switchable apparatuses. The built-in module provides a data supply and, for example, a power supply of a chain of serially interconnected apparatuses via two external plug-in locations being interconnected via an interposed distributor component that has an ethernet contact interface on a PCB of the built-in module for connecting within the apparatus, the built-in module to control electronics of the apparatus. The distributor component is configured here to distribute a data supply signal and optionally a power supply signal supplied by one of the two external plug-in locations to the other one of the two external plug-in locations and the ethernet contact interface on the PCB.
