Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate communication and power supply lines are used, then communication reliability is improved, but installation cost and complexity increase
Solution Approach 1:
The patent combines communication signal transmission and power supply functions into a single power line. The power line communication module transmits both power and communication signals through the same physical infrastructure, eliminating the need for separate communication cables and reducing installation complexity while maintaining system reliability through signal filtering and isolation techniques.
Solution Approach 2:
The power line is designed to serve multiple functions simultaneously: it provides both electrical power supply and communication signal transmission. This multi-functional approach allows the existing power infrastructure to be utilized for communication purposes, reducing the need for additional dedicated communication lines and simplifying the overall system architecture.
2Object-affected harmful factors
If separate communication and power supply lines are used, then signal interference is reduced, but installation space requirements increase
Solution Approach 1:
By merging communication and power transmission into a single line, the patent eliminates the need for separate communication cables, thereby reducing the installation space required. The filter unit separates power and communication signals within the same physical medium, preventing interference while maintaining space efficiency.
Solution Approach 2:
The filter unit acts as an intermediary component that separates power signals and communication signals within the same power line. This mediator prevents signal interference by filtering out unwanted frequencies while allowing both power and communication functions to coexist in the same physical infrastructure, thus reducing space requirements without compromising signal quality.
3Ease of manufacture
If Power Line Communication is implemented, then installation cost is reduced, but signal separation complexity increases
Solution Approach 1:
The filter unit serves as an intermediary device that automatically separates power and communication signals within the power line. This passive filtering approach reduces installation cost by eliminating the need for separate communication cables while managing signal separation complexity through straightforward electromagnetic filtering rather than complex active separation circuits.
Solution Approach 2:
The power line communication system utilizes the existing power infrastructure for both power supply and communication, making the system self-sufficient. The filter unit automatically performs signal separation without requiring additional complex control systems, thereby reducing installation cost while keeping signal separation manageable through passive filtering techniques.
4Loss of time
If Power Line Communication is implemented, then maintenance time is reduced, but power signal filtering complexity increases
Solution Approach 1:
The filter unit acts as an intermediary that handles power signal filtering automatically, reducing maintenance time by eliminating the need for manual signal separation during operations. The filtering complexity is managed through passive electronic components rather than complex active systems, making the overall maintenance simpler despite the added filtering function.
Solution Approach 2:
The filter unit performs power signal filtering autonomously without requiring external control or manual intervention, thereby reducing maintenance time. The filtering complexity is contained within the passive filter components, which require minimal maintenance compared to active signal processing systems, achieving a balance between automated filtering and ease of maintenance.
