Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple driving power supplies with different specifications are prepared to meet various LED lamp requirements, then the adaptability to different LED lamp configurations is improved, but the device complexity and inventory management difficulty increase
Solution Approach 1:
The patent applies universality by designing a single driving power supply with adjustable output parameters that can accommodate multiple LED lamp configurations. The driving power supply includes adjustable impedance elements and conductive connectors that allow it to function with different numbers and arrangements of LED beads, eliminating the need for multiple specialized power supplies.
Solution Approach 2:
The patent applies dynamics by making the driving power supply parameters adjustable rather than fixed. The impedance elements can be reconfigured and conductive connectors can be rearranged to change the output voltage and current characteristics dynamically, allowing one power supply to adapt to different LED lamp requirements.
2Device complexity
If a single driving power supply specification is used for all LED lamps, then the device complexity and inventory requirements are reduced, but the adaptability to meet different lighting requirements deteriorates
Solution Approach 1:
The patent implements universality by creating a standardized driving power supply design that can serve multiple LED lamp applications. Through configurable impedance elements and conductive connectors, a single power supply model can be universally applied to different LED lamp specifications while maintaining the ability to meet diverse lighting requirements.
Solution Approach 2:
The patent applies parameter changes by allowing the driving power supply's electrical parameters (voltage, current, impedance) to be adjusted through reconfigurable circuit elements. This enables a single power supply to deliver different output parameters suitable for various LED lamp configurations without requiring multiple specialized models.
3Reliability
If entire illumination devices are replaced when driving power supply is damaged, then the reliability of the lighting system is maintained, but the loss of resources and increased cost occur
Solution Approach 1:
The patent applies segmentation by separating the driving power supply from the LED lamp assembly into independently replaceable components. The driving power supply is designed as a modular unit with standardized connectors, allowing it to be replaced individually without discarding the LED lamp portion, thus reducing resource waste while maintaining system reliability.
Solution Approach 2:
The patent implements universality through standardized connection interfaces between the driving power supply and LED lamps. This universal interface design allows a replacement driving power supply to work with any compatible LED lamp, ensuring system reliability can be restored by simply replacing the faulty power supply unit rather than the entire illumination device.
