Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional single-channel optical components are used, then assembly precision can be maintained, but device complexity increases and productivity decreases
Solution Approach 1:
The patent combines multiple optical channels (transmit and receive channels) into a single butterfly-type packaged component. Instead of mounting separate single-channel components individually, the integrated multi-channel component allows all optical channels to be packaged together, reducing the number of individual mounting operations, gold wire bonding steps, hermetic sealing processes, and optical coupling operations required, thereby improving productivity and product yield while maintaining assembly precision
Solution Approach 2:
The butterfly-type packaged optical component is designed to perform multiple functions within a single device - it simultaneously handles multiple transmit channels and multiple receive channels. This multi-functional integration eliminates the need for separate single-channel components and their associated assembly processes, resolving the contradiction between maintaining precision and improving productivity
2Manufacturing precision
If individual mounting and optical coupling are performed for each component, then manufacturing precision can be ensured, but device complexity increases
Solution Approach 1:
The patent merges multiple optical coupling operations into a single integrated packaging process. By combining multiple transmit and receive channels into one butterfly-type package, the complex sequence of individual mountings, wire bondings, sealings, and optical couplings is consolidated into a unified assembly process, reducing overall process complexity while maintaining the precision required for each optical interface
3Reliability
If multiple separate optical components are used, then reliability can be maintained, but loss of energy increases
Solution Approach 1:
The patent reduces the number of optical interfaces and coupling points by integrating multiple channels into a single packaged component. Fewer separate components mean fewer optical coupling interfaces, which directly reduces transmission loss and energy dissipation while maintaining system reliability through the integrated design

AI summary
A butterfly-type packaged optical transceiver with multiple transmission and reception channels includes a box-shaped housing, a cover plate, an optical receiving module, an optical emitting module, a polarizing prism module, an optical fiber connector and electrical connection elements. The sealed housing encloses the optical receiving module, the optical emitting module, and the polarizing prism module. Electrical connection elements penetrate both side surfaces of the housing and are in contact with the optical fiber connector and the optical receiving module and the optical emitting module. A first incoming optical signal is transmitted to the optical receiving module via the optical fiber connector, the through hole, and the prism module, and the optical emitting module emits an outgoing second optical signal through the prism module, the through hole, and the optical fiber connector.
