Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If traditional isolator designs are used to ensure electrical isolation, then insulation performance is maintained, but communication speed is limited
Solution Approach 1:
The patent replaces traditional electrical isolation mechanisms with an optical isolation system. Optical components including lenses, reflection portions, and light transmitting portions create optical communication paths between electrically isolated regions, substituting electrical signal transmission with optical signal transmission to achieve both high-speed communication and electrical isolation
Solution Approach 2:
The patent introduces light as an intermediary medium to transfer information between electrically isolated regions. The light transmitting portion acts as a mediator that allows optical signals to pass through the isolation barrier without electrical connection, enabling communication while maintaining insulation performance
2Productivity
If optical components are used to increase communication speed, then data transmission improves, but device complexity increases
Solution Approach 1:
The patent combines multiple optical functions into a single integrated optical component. The optical component integrates first and second lens portions, reflection portions, and light transmitting portions into one unified structure, reducing the number of separate components and simplifying the overall device complexity while maintaining high data transmission capacity
Solution Approach 2:
The optical component is designed with multi-functionality, where a single component performs multiple optical functions including light focusing (lens portions), light direction control (reflection portions), and light transmission (light transmitting portions). This universal design reduces the number of separate components needed and simplifies the device structure

AI summary
A pair of optical components is used in an isolator that enables electric isolation. Each of the optical components includes: first lens portions arranged on different optical paths and transmitting light in a first direction; second lens portions arranged on different optical paths and transmitting light in the second direction orthogonal to the first direction; and a reflection portion reflecting, in the second direction, the light in the first direction transmitted through the first lens portion and guiding the light to the second lens portion, or reflecting, in the first direction, the light in the second direction transmitted through the second lens portion and guiding the light to the first lens portion The second lens portion included in one of the pair of optical components and the second lens portion included in the other optical component are spaced apart from each other and face each other.
