Solution Overview

Problem

Conventional refrigerant leak detection systems in air conditioning systems fail to operate during power failures, rendering them ineffective in detecting refrigerant leaks.

Innovation Solution

A refrigerant leak detection system equipped with a detection alarm and a power feed adapter that includes a main power supply unit and a sub power supply unit, such as a battery kit, allowing the system to continue operating during power failures by switching to battery power.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the refrigerant detection sensor is operated by power supplied from a commercial power source, then the system can operate normally under standard power conditions, but the refrigerant detection sensor cannot operate in the event of a power failure

Engineering Contradiction:
Improveoperational reliability during power failureVSAvoidpower supply system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

A backup battery is pre-installed in the power feed adapter to provide power supply in advance when commercial power fails, ensuring the refrigerant detection sensor can continue operating without interruption

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The backup battery serves as a cushioning power source that compensates for power supply interruptions before they affect system operation, maintaining detection functionality during commercial power failures

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

AI summary

A refrigerant leak detection system that detects a refrigerant leak from an air conditioning system. The system includes a detection alarm having a detection unit that detects leaking refrigerant and an alarm unit that alerts when the detection unit detects a refrigerant leak, a power feed adapter having a main power feed unit that supplies power to the detection alarm, and a sub power supply unit that is connected to the power feed adapter. The power feed adapter supplies power to the detection alarm from the sub power supply unit if the main power supply unit becomes unable to supply power to the detection alarm.
