Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If LED light strings are applied in AC power supply environments, then energy saving and environmental friendliness are improved, but control and regulation of LEDs to display different colors becomes difficult
Solution Approach 1:
The light string is divided into multiple independent light bars, each with its own control capability. The controller is segmented into functional modules (AC-DC rectifier, DC-DC voltage step-down, control circuit) that can independently manage different aspects of LED control, enabling color regulation while maintaining energy efficiency
Solution Approach 2:
The system employs dynamic control through pulse width modulation (PWM) signals generated by the control circuit. This allows real-time adjustment of LED brightness and color by varying the duty cycle of control signals, enabling flexible color display while operating efficiently on AC power supply
2Stability of the object's composition
If light bars are designed for fixed installation, then structural stability is improved, but assembly and disassembly convenience deteriorates
Solution Approach 1:
The light string system is segmented into modular light bars that can be independently assembled and disassembled. Each light bar contains complete functional units (LED display circuit, power signal input circuit), allowing flexible configuration while maintaining structural integrity when assembled
Solution Approach 2:
The threaded connector design allows light bars to be nested or串联 connected in series. The internal threaded structures enable one light bar to be inserted into and secured by another, creating a stable nested configuration that is easy to assemble and disassemble while maintaining structural stability
