Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual operation of the program in the control box is used for color switching, then the control process is simple, but the flexibility to adapt to variations in demand is poor
Solution Approach 1:
The patent introduces a remote control device as an intermediary between the user and the light string assembly. This remote control communicates wirelessly with the control box, allowing users to change colors and modes without manually operating the program in the control box. This resolves the contradiction by providing flexibility (multiple color/mode options accessible remotely) while keeping the control system itself relatively simple.
Solution Approach 2:
The light string assembly includes an intelligent power supply with built-in control capabilities that can automatically manage color switching and lighting effects. The system serves itself by having the control box receive and process control signals (either from remote control or preset programs) to automatically adjust the LED lighting without requiring manual intervention in the control box programming.
2Adaptability or versatility
If the structure of the light string assembly is simple, then the device complexity is low, but the ability to achieve desired curtain-like or array-like decorative effects is insufficient
Solution Approach 1:
The light string assembly is divided into multiple independent light strings that can be connected in series or parallel configurations. Each light string contains multiple LED bulbs that can be individually controlled or grouped. This segmentation allows the system to achieve complex decorative effects (curtain-like, array-like patterns) by coordinating multiple segments while keeping each individual segment relatively simple in structure.
Solution Approach 2:
The light string assembly is designed with universal connectors and control capabilities that allow it to be configured for multiple decorative applications. The same basic structure can be arranged to create curtain-like effects, array-like patterns, or other decorative configurations. The intelligent power supply and control system provide multi-functionality by supporting various lighting modes, colors, and synchronization patterns without requiring different physical structures.
3Reliability
If multiple light strings are controlled independently, then the control flexibility is high, but the synchronization effect across light strings is difficult to achieve
Solution Approach 1:
The patent merges the control functions for multiple light strings into a single intelligent power supply unit. This central化的 control system receives control signals and distributes them to multiple light strings simultaneously, ensuring they change colors and modes in synchronization. The merging of control functions achieves reliable synchronization while actually reducing overall system complexity compared to having independent control systems for each light string.
Solution Approach 2:
The control system incorporates feedback mechanisms to monitor the state of multiple light strings and adjust control signals to maintain synchronization. The intelligent power supply detects the status of connected light strings and coordinates their operation to achieve consistent lighting effects across all strings, ensuring reliable synchronization through continuous monitoring and adjustment.

AI summary
Disclosed is a white and warm white LED synchronous intelligent light string assembly, which includes a white LED chip and a warm white LED chip arranged inside the light bead, and the control IC can control different flashing modes of the LED chips after receiving commands. One end of the IP44 plug is connected to a 24-230V power supply, and the other end of the plug is connected to a fuse for current limitation, a varistor for voltage control, a filter for filtering out noise and separating signals, and a filter circuit for passing the low frequencies and attenuating the high frequencies. Outputs of the filter circuit are respectively connected to an input of the MOSFET and a DCDC transformer. The DCDC transformer outputs a direct current with an altered voltage to a driver and an IRF. The IRF is connected with a program module, a remote-control module and a WiFi & Bluetooth module, and the signal output by the IRF passes through the driving module, both of outputs of the driving module and the DCDC transformer are connected to an input of MOSFET while an output of MOSFET is connected to one end of the main wire.
