Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple LED lamp strings are connected in series with separate power circuits, then each lamp string can be independently controlled, but the cost increases due to inability to share power circuits
Solution Approach 1:
The system divides the LED lamp strings into segments (first LED apparatus and second LED apparatus) that can be connected in series. Each segment contains its own LED modules connected in series, allowing the entire system to share a common power circuit while maintaining segment-level control capabilities through the connectors and control units.
Solution Approach 2:
The connector is designed with multi-functionality, serving both as an electrical connection point for power transmission and as a control signal transmission path. The control unit can transmit control signals through the same connector infrastructure used for power distribution, enabling independent control of different LED apparatus segments without requiring separate control circuits.
2Manufacturing precision
If separate power circuits are used for each LED lamp string, then control precision is maintained, but manufacturing cost increases
Solution Approach 1:
The invention merges the power transmission and control signal transmission functions into a single connector infrastructure. The control unit transmits both power and control signals through the same connector connections that link LED modules in series, reducing the number of separate circuits needed while maintaining precise control over color and intensity of each LED apparatus segment.
Solution Approach 2:
The connector acts as an intermediary that facilitates both power delivery and control signal transmission between LED modules. By using the connector as a dual-purpose intermediary component, the system achieves precise control without requiring separate dedicated control wiring for each LED string, thereby reducing manufacturing complexity and cost.

AI summary
A light emitting diode system includes a first light emitting diode apparatus and a second light emitting diode apparatus. The first light emitting diode apparatus includes an alternating-current-to-direct-current and light-controlling unit, a plurality of first light emitting diode modules and a first connector. The second light emitting diode apparatus includes a second connector, a signal-converting unit and a plurality of second light emitting diode modules. The first light emitting diode apparatus outputs a drive direct current power and a light-controlling signal to the signal-converting unit through the first connector and the second connector. Therefore, the signal-converting unit is configured to control colors and intensities of the second light emitting diode modules.
