Solution Overview
Problem
The LED display industry faces challenges in mass production efficiency due to the diversity of materials and dispersion of LED packaging structures, which hinders the uniform sourcing of materials and standardization of hubs, leading to inefficiencies in production.
Innovation Solution
An auxiliary display device with a shared hub featuring dual input and independent output ports, capable of receiving and delivering dual supply voltages to both common anode and common cathode LED modules, facilitating unified material requirements and standardized hub specifications, thereby improving production efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate hubs are used for common anode and common cathode LED modules, then each LED type can be optimized independently, but material sourcing becomes dispersed and production efficiency decreases
Solution Approach 1:
The hub is designed with a universal interface that can accommodate both common anode and common cathode LED modules through selectable connection modes. The hub contains switching circuits that can configure the connection topology to match the LED module type, allowing a single hub design to serve multiple LED configurations without requiring separate specialized hubs for each LED type.
2Ease of manufacture
If different packaging structures are used for common anode and common cathode LEDs, then each can be manufactured with optimized processes, but material procurement becomes complex and standardized
Solution Approach 1:
The hub incorporates selectable connection modes that change the electrical parameters and connection topology based on the LED module type detected or selected. By adjusting the connection configuration within the hub, the same physical hub can adapt to different LED packaging structures (common anode or common cathode), effectively standardizing the hub interface while accommodating diverse LED manufacturing approaches.
