Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If flash bulbs are directly connected in series to LED light strings, then dynamic flashing effect is achieved, but current consumption increases and luminescence becomes unsteady
Solution Approach 1:
The patent introduces a control module as an intermediary between the power source and LED lights. This module includes a bridge driving circuit that converts DC power to AC power, enabling proper driving of LED lights with flash bulbs without direct series connection, thus maintaining luminescence stability while achieving flashing effects
Solution Approach 2:
The patent divides the lighting system into separate functional modules: a control module with bridge driving circuit for power conversion and control, and LED light strings for illumination. This segmentation allows independent optimization of each module, enabling stable operation of LEDs while incorporating flash bulbs for dynamic effects
2Ease of manufacture
If flash bulbs are directly connected to LED light strings, then flashing effect is achieved, but current fluctuation increases affecting safety
Solution Approach 1:
The control module serves as a protective intermediary that regulates power delivery to both LED lights and flash bulbs. The bridge driving circuit within this module controls current flow, preventing dangerous fluctuations while enabling the flashing effect, thus maintaining safety without compromising installation simplicity
Solution Approach 2:
The patent incorporates protection circuits within the control module that preemptively prevent current overfluctuation. These circuits monitor and regulate power delivery before harmful fluctuations can occur, cushioning against potential safety risks while allowing flash bulbs to operate
3Ease of operation
If button switch control is used for LED lights, then simple operation is achieved, but intelligent control capability is lacking
Solution Approach 1:
The control module is designed with multi-functionality, supporting both traditional button switch operation and Bluetooth wireless control. This universal design allows the system to maintain simple local control while gaining intelligent remote control capabilities through a mobile terminal application
Solution Approach 2:
The patent introduces a mobile terminal application as an intermediary for intelligent control. This application communicates with the control module via Bluetooth, providing enhanced control capabilities including mode selection, timing functions, and memory storage, while the button switch remains available for direct operation
4Adaptability or versatility
If Bluetooth wireless control is added to LED controller, then intelligent control capability is improved, but device complexity increases
Solution Approach 1:
The patent uses a mobile terminal application as an intermediary for intelligent control functions. This approach offloads complex control logic to the user's smartphone, keeping the actual controller relatively simple while still providing advanced features through wireless communication
