Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional indicator lights with separate light guide rod and light shade are used, then the structure is relatively complex, but the light transmitting effect is relatively poor
Solution Approach 1:
The patent integrates the light guide rod and light shade into a single integrated component. The light guide rod and light shade are formed as one piece through injection molding, eliminating the need for separate components and assembly steps. This merging resolves the contradiction by simplifying the structure while maintaining or improving light transmission efficiency through optimized integrated geometry.
2Device complexity
If conventional indicator lights with single indicating surface are used, then the structure is simple, but the light is only observable from a particular angle
Solution Approach 1:
The patent adds multiple indicating surfaces to the light shade, transforming it from a single-face indicator to a multi-face indicator. The light shade includes front, side, and slanted indicating surfaces that face different directions, allowing light to be observed from multiple angles. This dimensional expansion resolves the contradiction by improving adaptability while the integrated design keeps structural complexity manageable.
3Device complexity
If conventional converter plugs are connected to socket simply by prongs, then the connection structure is simple, but the connection is not secure and can result in poor contact
Solution Approach 1:
The patent divides the connection function into multiple components: prongs for electrical contact and a positioning bracket for mechanical security. The positioning bracket includes a body with connecting members that engage with the socket, providing additional anchoring beyond the prongs alone. This segmentation resolves the contradiction by improving reliability through functional division while keeping each component relatively simple.
Solution Approach 2:
The positioning bracket acts as an intermediary component between the converter plug and the socket. It provides an additional connection interface that mediates the mechanical attachment, ensuring secure positioning while allowing the prongs to maintain their electrical contact function. This intermediary element resolves the contradiction by enhancing connection security without significantly complicating the overall structure.

AI summary
An indicator light, an electrical converter plug, a positioning bracket, and an electrical converter plug assembly. The indicator light for indicating a working status of the electrical device includes a light guide rod having opposite first and second ends, and a light shade, disposed at the first end of the light guide rod and including multiple indicating surfaces facing different directions. When the indicator light is installed on the electrical device, the second end of the light guide rod faces a light source inside the electrical device, and light from the light source is guided by the light guide rod to the light shade and emitted in the multiple directions by the light shade, allowing the user to observe the light from multiple angles. Further, a positioning bracket affixes the electrical converter plug to the power outlet socket, ensuring secure contact, prolonging product life, and eliminating safety threat.
