Dynamic Power Allocation in Distribution Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Power distribution modules (PDMs) are often oversized due to peak demand sizing, leading to inefficient use of electrical resources as loads typically operate at lower power levels, resulting in wasted energy and increased installation and maintenance costs.
Innovation Solution
A power distribution module (PDM) with a controller and switches that dynamically allocate power based on measured demand, allowing unused power from one output channel to be shared with others, optimizing power utilization and reducing the need for oversized infrastructure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If circuits are sized based on peak demand to ensure sufficient power capacity, then power supply reliability is improved, but electrical resource efficiency deteriorates due to oversized circuits operating at lower power levels
Solution Approach 1:
The patent implements dynamic power allocation by dividing the power distribution module into multiple independently controllable output channels with individual switches. Each channel can be dynamically enabled or disabled based on actual power demand, allowing the system to adapt between peak and non-peak operating conditions. This dynamic configuration resolves the contradiction by maintaining reliability through available capacity while improving efficiency by activating only needed circuits.
Solution Approach 2:
The power distribution module is segmented into multiple output channels, each with its own switch and control capability. This segmentation allows independent management of power delivery to different loads, enabling the system to optimize power distribution by activating only the channels currently in use rather than maintaining all circuits at peak capacity.
2Power
If power distribution modules are oversized to meet peak demand requirements, then power capacity is sufficient, but installation and maintenance costs increase
Solution Approach 1:
The system uses dynamic switching control to enable or disable output channels based on actual power requirements. This allows the use of standardized, smaller-capacity circuitry that can be dynamically configured to meet peak demands when needed, rather than requiring permanently oversized infrastructure that increases installation and maintenance costs.
Solution Approach 2:
The patent changes the operational parameters of the power distribution system by introducing controllable switches that can alter the effective power capacity of output channels. This allows the system to flexibly adjust power delivery capabilities to match actual load requirements, avoiding the need for permanently oversized equipment.
3Reliability
If all output channels are always active to ensure power availability, then power access reliability is improved, but energy consumption increases due to unused power delivery
Solution Approach 1:
The patent implements dynamic control of output channels through individual switches that can be enabled or disabled based on actual power需求的. This dynamic approach ensures that power delivery is available when needed while preventing energy waste by keeping unused channels inactive, thereby resolving the contradiction between reliability and energy consumption.
Solution Approach 2:
The system incorporates automatic power management where the controller monitors power demands and autonomously activates or deactivates output channels as needed. This self-service capability ensures power availability when required while minimizing energy consumption by automatically disabling unused channels without requiring continuous operation.

AI summary
A power distribution module (PDM) can include an input portion configured to receive high-voltage (HV) power from a power source. The PDM can also include a power transfer device electrically coupled to the input portion, where the power transfer device is configured to generate at least one low-voltage signal using the HV power. The PDM can further include an output section electrically coupled to the power transfer device and including a number of output channels. The PDM can also include at least one switch disposed between the output section and the power transfer device, where the at least one switch has an open position and a closed position. The PDM can further include a controller communicably coupled to the at least one switch, where the controller operates the at least one switch between the closed position and the open position based on a power demand measured at the output section.
