Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical equipment protection systems, such as arc protectors, fail to address rising temperatures and prevent fires in electrical circuits, leading to potential destruction or fire, as they lack extinguishing capabilities and temperature control.
Innovation Solution
An automatic communication system comprising a transmitter with a cooling medium carrier and a receiver at the electrical power source, using wireless communication to disconnect power and release a fire-extinguishing cooling medium when temperature rises, ensuring safe and efficient suppression of fires and temperature control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If arc protectors are used to disconnect electrical sources, then electrical short circuits are mitigated, but rising temperatures and fire hazards are not prevented
Solution Approach 1:
The patent combines the arc protector's circuit disconnection function with a fire extinguishing function by integrating a cooling medium carrier and release mechanism into the same device. This merging allows the system to simultaneously address both electrical short circuits and fire hazards that arc protectors alone cannot handle.
Solution Approach 2:
The device is designed to perform multiple functions: it protects against electrical short circuits through circuit disconnection while also suppressing fires through the release of cooling medium. This multi-functionality resolves the contradiction by making a single device capable of addressing both electrical and thermal hazards.
2Reliability
If traditional protection systems are used, then electrical circuits are protected, but temperature monitoring and fire suppression capabilities are lacking
Solution Approach 1:
The system integrates temperature sensing, circuit disconnection, and fire extinguishing functions into a single protective device. This universal design allows the same device to monitor temperature, detect faults, disconnect circuits, and suppress fires, thereby achieving both electrical protection and thermal management capabilities.
Solution Approach 2:
The device automatically detects temperature rises and activates the fire extinguishing mechanism without external intervention. The temperature sensor triggers the release of cooling medium when threshold temperatures are reached, enabling the system to self-regulate and respond to thermal hazards autonomously.
3Object-affected harmful factors
If a cooling medium carrier with fire extinguishing effect is integrated, then fire suppression capability is achieved, but device complexity increases
Solution Approach 1:
The cooling medium carrier is designed as a disposable component that is pre-filled with fire-extinguishing material. When activated, it releases the cooling medium and is then discarded, avoiding the need for complex rechargeable systems. This approach reduces overall device complexity while maintaining effective fire suppression capability.
Solution Approach 2:
The fire extinguishing mechanism utilizes pneumatic pressure to force the cooling medium out of the carrier when activated. This simple pneumatic release mechanism, based on pressure differential, avoids complex mechanical or electronic actuation systems, thereby minimizing the increase in device complexity while achieving reliable fire suppression.
