Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the structure of the optical transceiver module is expanded or completely changed to improve transmission capacity, then the transmission capacity is improved, but the structure becomes more complicated and production requirements increase
Solution Approach 1:
The optical transceiver module is divided into multiple independent modules: optical module, electrical module, and mechanical module. Each module can be manufactured, tested, and replaced independently. The optical module includes optical transmitting/receiving units, wavelength division multiplexing/demultiplexing units, and optical fibers. This segmentation allows the system to achieve high transmission capacity through modular expansion without increasing overall structural complexity, as each module follows standardized interfaces and connection protocols.
2Ease of manufacture
If conventional production process is used, then manufacturing can be performed, but the production process is complicated and production efficiency is low
Solution Approach 1:
The production process is segmented into independent manufacturing stages for each module (optical module, electrical module, mechanical module), allowing parallel production. Each module can be manufactured, assembled, and tested separately using dedicated production lines, then finally integrated. This eliminates the need for complex sequential assembly processes and significantly improves production efficiency.
Solution Approach 2:
Each module is pre-manufactured, pre-tested, and pre-assembled independently before final integration. Quality control and testing are performed in advance during module manufacturing, ensuring that only qualified modules proceed to assembly. This preliminary action reduces rework and ensures smooth final integration, improving overall production efficiency.
3Ease of operation
If conventional production process is used, then components can be assembled, but components must be assembled in predetermined order resulting in long production cycle
Solution Approach 1:
The assembly process is segmented into independent module assembly operations that can be performed in parallel. The optical module, electrical module, and mechanical module are assembled simultaneously in separate workstations, then integrated in a final assembly step. This eliminates sequential assembly constraints and significantly reduces the production cycle time.
4Productivity
If conventional production process is used, then the optical transceiver module can be produced, but failure of any process wastes all previous processes resulting in poor production performance
Solution Approach 1:
The optical transceiver module is divided into independent replaceable modules that can be manufactured and tested separately. If a failure occurs during assembly or operation, only the faulty module needs to be replaced, not the entire transceiver module. This segmentation minimizes material waste by preserving functional components and reduces production loss by allowing selective replacement of failed modules.

AI summary
A method for designing a high-speed multichannel optical module. Components in an optical module are classified into a circuit part and an optical path part according to functions, and the circuit part and the optical path part are separately processed and then assembled to be an optical module. Thus, modular production is implemented, and multiple parts can be processed at the same time, thereby improving the production efficiency. Moreover, if any fault occurs to either of the parts, the part can be independently replaced and maintained, thereby preventing the entire optical module from being scrapped, facilitating control of the production costs, and improving the yield rate. Also disclosed in the present invention is a high-speed multichannel optical module, which is manufactured according to the design method above. The high-speed multichannel optical module employs a modular structure, and comprises a circuit part and an optical path part which are electrically connected. The structure is simple, and expansion and upgrade are facilitated.
