Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional bulb set structure is used, then the structure is simple, but it cannot convert alternating current into direct current causing inconvenience
Solution Approach 1:
The patent combines the power converting unit with the plug housing by receiving the power converting unit inside the plug housing, integrating multiple functions (AC to DC conversion, power distribution) into a single compact device. This resolves the contradiction by achieving current conversion capability while maintaining relatively simple integrated structure.
Solution Approach 2:
The plug is designed with multi-functionality: it serves as both a connection device and a power conversion device. The plug housing receives both the power converting unit and the LED bulb set, allowing the same structure to handle both conversion and distribution functions, thus improving adaptability without proportionally increasing complexity.
2Reliability
If conventional bulb set with voltage stabilizer is used, then voltage can be stabilized, but it causes short circuit on rainy day
Solution Approach 1:
The patent segments the internal components by providing separate receiving spaces: the power converting unit is received in a first space and the LED bulb set in a second space. This segmentation allows for better isolation and protection of electrical components, improving short circuit prevention while maintaining waterproof performance through structured compartmentalization.
Solution Approach 2:
The power converting unit is nested within the plug housing structure, which itself is designed with waterproof considerations. The nested arrangement allows the outer housing to protect the inner components from water ingress, resolving the contradiction between reliability and waterproof performance.
3Ease of operation
If alternating current is required, then extend power cord has to be used, but it causes inconvenience
Solution Approach 1:
The plug is designed with universal functionality to output both alternating current (through the fitter) and direct current (through the LED bulb set connection). This multi-functionality eliminates the need for separate extend power cords for different power types, improving ease of operation while maintaining power output flexibility.
Solution Approach 2:
The patent combines AC and DC output capabilities in a single plug device. The power converting unit enables DC output while the fitter maintains AC output capability, merging both power delivery modes into one integrated solution that eliminates the need for additional extend cords.
4Adaptability or versatility
If power converting unit is added, then alternating current can be converted to direct current, but device complexity increases
Solution Approach 1:
The power converting unit is merged with the plug housing structure, receiving the unit inside the housing. This integration reduces the need for separate external conversion devices, achieving current conversion capability while minimizing the increase in overall device complexity through compact integration.
