Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If high voltage cables are used to provide power to construction sites, then power distribution capability is improved, but safety risks (electrocution and fire) increase
Solution Approach 1:
The patent introduces a mobile power distribution station as an intermediary device that converts high voltage power to low voltage power before distribution. The station includes a high voltage input connector, power conversion circuitry, and multiple low voltage output ports, acting as a mediator between the high voltage power source and the construction site equipment, thereby eliminating the need for high voltage cables on site while maintaining power distribution capability
Solution Approach 2:
The patent changes the voltage parameter from high voltage to low voltage through the mobile power distribution station. The station accepts high voltage AC power input and converts it to low voltage DC power output, fundamentally changing the electrical parameter to eliminate safety risks associated with high voltage while preserving the ability to power construction equipment
2Power
If high voltage cables are installed on construction sites, then power supply capability is improved, but complexity of installation and specialized labor requirements increase
Solution Approach 1:
The mobile power distribution station serves as a self-contained intermediary unit that integrates power conversion and distribution functions. It includes an AC power input connector for high voltage input, internal power conversion circuitry, and multiple DC output ports, eliminating the need for complex high voltage cable installation and specialized electrician labor
Solution Approach 2:
The patent merges multiple functions (power conversion, cable management, and distribution) into a single mobile power distribution station unit. This integration eliminates the need for separate high voltage cables, distribution panels, and specialized installation procedures, simplifying the overall system to a plug-and-play solution
3Power
If high voltage power distribution system is implemented, then power delivery capability is improved, but costs of mitigation and compliance increase
Solution Approach 1:
The patent employs inexpensive, temporary wiring solutions connected to the mobile power distribution station instead of permanent high voltage infrastructure. The system uses standard low voltage DC cables and connectors that are inexpensive and do not require costly compliance certifications, making it suitable for temporary construction site applications
Solution Approach 2:
By changing the power delivery parameter from high voltage AC to low voltage DC, the patent eliminates the need for expensive high voltage compliance measures, licensed electrician installation, and complex safety mitigation infrastructure, significantly reducing overall system cost while maintaining adequate power delivery capability for construction equipment
