Engineering Contradiction Analysis
1Productivity
If multi-channel optical receiving and transmitting technology is employed to achieve high transmission rate, then transmission rate is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple optical receiving and transmitting channels into a single integrated optical module structure. Multiple light reception components and light emission components are integrated within one module, sharing common structural elements and optical paths, thereby achieving high transmission rates while controlling device complexity through systematic integration.
Solution Approach 2:
The optical module is designed with multi-functional components that can handle multiple wavelengths and channels. The wavelength division multiplexer and optical assembly enable a single module to perform both receiving and transmitting functions across multiple channels, reducing the need for separate dedicated components for each function.
2Productivity
If multi-channel optical receiving and transmitting technology is employed to achieve high transmission rate, then transmission rate is improved, but module size increases
Solution Approach 1:
The patent implements a nested structure where multiple light reception components and light emission components are arranged within a compact optical assembly. The wavelength division multiplexer and optical elements are integrated in a nested configuration, allowing multiple functional elements to occupy overlapping or adjacent spatial volumes, thereby reducing the overall module size while maintaining multi-channel capability.
Solution Approach 2:
The optical components are arranged in three-dimensional space with optimized spatial positioning. The patent uses vertical stacking and angular arrangements of optical elements to utilize multiple dimensions, transforming a potentially planar layout into a compact volumetric structure that reduces the module's footprint while accommodating multiple channels.
3Adaptability or versatility
If multiple light reception components are provided at intervals in the first cavity member, then multi-wavelength signal reception is improved, but device complexity increases
Solution Approach 1:
The patent divides the optical reception function into multiple discrete light reception components, each potentially optimized for specific wavelength ranges. These segmented components are arranged at intervals in the first cavity member, allowing independent optimization of each component while maintaining overall system functionality through modular architecture.
Solution Approach 2:
The wavelength division multiplexer acts as an intermediary device that manages the separation and routing of different wavelength signals to the appropriate light reception components. This intermediary element simplifies the complexity by providing a systematic method for wavelength-based signal distribution, reducing the need for complex routing logic in each individual component.
