Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If one gateway unit is assigned per electrical module, then each module can be independently managed and processed, but the cost and device complexity increase significantly
Solution Approach 1:
The patent combines multiple gateway units into a single integrated gateway device that can handle signals from multiple electrical modules simultaneously. The gateway includes a control circuit with multiple input channels, each capable of receiving and processing modulated power signals from different modules, thereby reducing the total number of gateway units needed while maintaining independent module management capability
Solution Approach 2:
The gateway unit is designed with multi-functional capability to manage multiple electrical modules through a single device. The control circuit can selectively process signals from different modules, and the injection circuit can interface with multiple phases of the electrical grid, making the gateway universal rather than dedicated to a single module
2Reliability
If multiple gateway units are used to handle multiphase grids, then complete signal processing is achieved, but the installation area and device complexity increase
Solution Approach 1:
The patent integrates multiple signal processing functions into a single gateway device that can handle multiphase grids. The control circuit includes multiple input channels that can simultaneously process modulated signals from different modules connected to different phases, consolidating what would traditionally require separate gateway units into one compact device
Solution Approach 2:
The gateway unit is designed to process signals across multiple dimensions simultaneously - it can handle multiple phases (L1, L2, L3) and multiple modules through a unified control architecture. This dimensional expansion allows single-device handling of complex multiphase configurations that previously required multiple sequential processing units
3Manufacturing precision
If each gateway unit includes complete filtering and control circuits, then signal processing quality is maintained, but manufacturing cost increases
Solution Approach 1:
The patent consolidates multiple filtering circuits and control circuits into a single shared infrastructure within the gateway device. The control circuit serves multiple input channels simultaneously, and the injection circuit handles multiple phases through unified control logic, reducing the total component count and manufacturing cost while maintaining signal processing quality through dedicated processing paths for each channel
