Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional low voltage power distribution systems are used, then power can be delivered to devices, but the systems are not safe under current standards and pose risks of fire and electrical shock
Solution Approach 1:
The system segments power distribution into multiple independent PDM modules, each capable of operating autonomously. This segmentation allows the system to meet safety standards by isolating fault domains and enabling Class 2 circuit compliance, thereby reducing fire and electrical shock risks while maintaining reliable power delivery.
Solution Approach 2:
The patent introduces communication links as intermediaries between PDM modules and POL control devices. These communication links enable intelligent power management and monitoring, allowing the system to dynamically adjust power delivery to meet safety standards while preventing harmful effects through real-time control.
2Ease of operation
If traditional power distribution systems are used, then power delivery is achieved, but licensed electrical professionals are required for installation and maintenance costs are high
Solution Approach 1:
The PDM modules are designed with integrated power conversion and communication capabilities, enabling them to self-configure and self-manage power distribution. This self-service capability eliminates the need for licensed electrical professionals during installation and maintenance, reducing operational complexity despite the advanced functionality.
Solution Approach 2:
The patent creates universal PDM modules that can serve multiple functions: power conversion, communication hosting, and intelligent power management. This multi-functionality reduces the need for separate specialized components, simplifying installation while maintaining sophisticated power distribution capabilities.
3Extent of automation
If individual POL control modules are used for each device, then precise power control is achieved, but system complexity and cost increase
Solution Approach 1:
The patent merges the POL control functionality into the PDM modules themselves, eliminating the need for separate individual control modules at each device. This consolidation maintains precise power control through the communication links while significantly reducing system complexity and the total number of control components required.
