Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If diesel generators are used to power telecommunication equipments, then uninterrupted power supply is achieved, but operational cost increases and greenhouse gas emissions occur
Solution Approach 1:
The patent extracts only the necessary power supply function from the conventional diesel generator system by tapping power directly from existing high voltage transmission lines through a capacitor divider circuit and step-down transformer, eliminating the need for fuel combustion and associated emissions while maintaining reliable power supply
Solution Approach 2:
The patent introduces a capacitor divider circuit and step-down transformer as intermediary components between the high voltage transmission line and the telecommunication equipment, enabling safe voltage reduction and power extraction without direct connection to the transmission line, thus achieving clean and reliable power supply
2Loss of energy
If solar panels are installed to provide power, then renewable energy is used, but installation becomes cumbersome and footprint increases
Solution Approach 1:
The patent utilizes existing high voltage transmission lines that already traverse the location for dual purposes: both power transmission and local power supply to telecommunication equipment, eliminating the need for separate solar panel installations and reducing overall system complexity
Solution Approach 2:
The patent enables the existing transmission infrastructure to serve itself by allowing telecommunication equipment to draw power directly from the transmission lines passing through the same location, eliminating the need for external power generation infrastructure
3Reliability
If battery banks are added for power storage and backup, then uninterrupted power is ensured, but device complexity and footprint increase
Solution Approach 1:
The patent extracts stable voltage directly from the transmission line through a capacitor divider circuit, eliminating the need for battery banks by obtaining continuous power from the existing transmission infrastructure that already provides reliable service
4Ease of manufacture
If dedicated telecommunication towers are constructed, then infrastructure for equipment installation is provided, but cost and installation time increase
Solution Approach 1:
The patent merges the power supply function with the existing transmission line infrastructure, allowing telecommunication equipment to be powered directly from the transmission lines without requiring separate dedicated towers or infrastructure construction
