Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If low voltage DC electrical wiring is extended to reach distant locations, then access to power outlets is improved, but voltage drop increases causing power delivery problems
Solution Approach 1:
The patent divides the electrical system into modular segments: a main line carrying high voltage AC power, and multiple branch lines carrying low voltage DC power to different locations. This segmentation allows the system to extend coverage while maintaining voltage stability through the high voltage backbone.
Solution Approach 2:
The patent introduces a DC electrical converter as an intermediary device that transforms high voltage AC power from the main line into low voltage DC power for distribution on branch lines. This intermediary conversion enables long-distance power delivery by first transmitting power efficiently at high voltage, then converting to usable low voltage at distribution points.
2Adaptability or versatility
If multiple electrical outlets are provided in high-density areas, then user access to power is improved, but system complexity increases
Solution Approach 1:
The patent creates a universal electrical system architecture where a single main line with AC power can serve multiple branch lines with different low voltage DC outlet configurations. Each outlet location can be customized for specific devices (USB, coaxial, automotive connectors) while sharing the common high voltage AC infrastructure, reducing overall system complexity.
Solution Approach 2:
The patent applies local quality by allowing different types of electrical outlets and connectors at different branch line locations based on specific user needs. Each outlet can be customized with appropriate connectors (USB for data devices, coaxial for audio/video, automotive for high power) while maintaining a standardized main line architecture.
3Ease of operation
If detachable connectors are used for branch lines, then ease of installation and reconfiguration is improved, but connection reliability may decrease
Solution Approach 1:
The patent implements dynamic connectivity by using detachable connectors that allow branch lines to be easily connected and disconnected from the main line. This dynamic design enables flexible installation, reconfiguration, and maintenance while maintaining reliable electrical connections through properly engineered connector interfaces.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system ensures multiple users have reliable access to high and low voltage power in high-density areas like stadiums and public transportation, extending the length of low voltage systems while maintaining sufficient voltage and providing flexible, modular power distribution.
Implementation Method 1
A DC electrical converter is disposed between the power source and the first end of the main line. The DC electrical converter is operable to convert a high voltage AC power input at the power source to a low voltage DC power output at the first end portion of the main line.
Implementation Method 2
To account for voltage drop along a length of DC-energized electrical wiring, one or more power boosters may be coupled along the electrical wiring
Data Source
AI summary
A branched electrical system is adapted for providing multiple users with access to high and/or low voltage electrical power in work areas or high density seating areas, such as stadium or theater seating, work rooms, lecture halls, and public transportation vehicles. The system includes a main line and a plurality of branch lines, each branch line having at least one high voltage or low voltage electrical receptacle that is accessible to a user located at the seating, such as for powering a portable electronic device. The branch lines may be coupled to the main line via a splice or other electrical-mechanical connection.
