Solution Overview
Problem
Conventional power sourcing devices face challenges in managing heat dissipation and preventing overheating, leading to performance inefficiencies and vulnerability to damage, as they often require expensive cooling solutions that increase size and compromise functionality.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If power is allocated to ports as per requirement, then power delivery capability is improved, but temperature of ports and connectors increases leading to overheating
Solution Approach 1:
The patent implements dynamic power allocation that adjusts power distribution in real-time based on temperature conditions. The system continuously monitors port temperatures and dynamically redistributes power from overheated ports to cooler ports, enabling the power delivery capability to adapt to thermal conditions rather than being static
Solution Approach 2:
The system changes the power allocation parameter based on temperature measurements. When a port exceeds a threshold temperature, the system modifies the power parameter by reducing allocation to that port and redistributing it to other ports, thereby maintaining power delivery while controlling temperature
2Temperature
If cooling solutions are used to manage overheated components, then temperature control is improved, but device size and cost increase
Solution Approach 1:
The patent replaces mechanical cooling systems (such as fans, heat sinks, or liquid cooling) with an electrical control system that redistributes power dynamically. This substitution eliminates the need for bulky cooling hardware while achieving effective temperature management through intelligent power allocation
Solution Approach 2:
The system uses its own power distribution mechanism to manage temperature without external cooling assistance. By redistributing power internally based on temperature feedback, the system serves its own thermal management needs without requiring additional cooling components
3Power
If power is allocated to ports as per requirement, then power delivery capability is improved, but vulnerability to damage due to overheating increases
Solution Approach 1:
The patent implements a feedback mechanism where temperature sensors continuously monitor port conditions and feed this information back to the power management system. Based on this feedback, the system automatically adjusts power allocation to prevent overheating, thereby protecting components while maintaining power delivery capability
Solution Approach 2:
The system takes preliminary action by monitoring temperatures and redistributing power before critical overheating damage occurs. By detecting temperature trends and preemptively adjusting power allocation, the system prevents damage rather than reacting after failure occurs
