Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If power connectors have similar physical configurations, then manufacturing and assembly are simplified, but user identification and selection of correct connectors becomes difficult
Solution Approach 1:
The patent applies asymmetry by making the third pin offset from the first and second pins, creating a unique asymmetric configuration that allows users to easily identify and distinguish the connector type and pin positions, while still maintaining standardized manufacturing processes for the connector components
2Reliability
If electrical components are added for type verification, then connector compatibility is ensured, but device complexity increases
Solution Approach 1:
The electronic device performs self-verification by detecting the presence and configuration of the third offset pin to automatically identify the connector type and determine compatibility, eliminating the need for additional verification components or complex manual checking procedures

AI summary
A multi-pin power connector for a solar accessory is described. In some examples, the power connector has three pins that can be used for identifying a proper solar accessory for an electronic device. In one particular example, a power connector apparatus includes a connector head that is configured to supply power from a solar device to an electronic device. The connector head includes a first electrical connector that is positioned on a first side of the connector head, a second electrical connector that is positioned on a second side of the connector head, and a third electrical connector that is offset from the first electrical connector and the second electrical connector.
