Solution Overview

Problem

Mist cooling apparatuses are vulnerable to damage due to rising temperature and pressure during power failures, as the cooling process halts, potentially causing damage to the treatment object and equipment.

Innovation Solution

A dual cooling system is implemented, where a secondary cooling system operates independently using an emergency power supply to continue cooling the treatment object even when the primary power source is stopped, ensuring continuous cooling through a pump and nozzles or a storage tank, preventing equipment damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a mist cooling system is used to achieve high cooling efficiency and controllable cooling rate, then cooling performance is improved, but the system becomes vulnerable to damage during power failures due to loss of cooling function

Engineering Contradiction:
Improvecooling efficiencyVSAvoidsystem safety during power failure
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The invention introduces a backup power supply system that is activated in advance during power failures to maintain pump operation and cooling function. This preliminary action ensures that the cooling system continues to operate when main power is lost, preventing temperature and pressure buildup that could damage the apparatus.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The invention provides a safety net by equipping the system with emergency power supply equipment (such as a generator) that kicks in during power failures. This beforehand cushioning measures ensures continuous cooling operation, protecting the system from the harmful effects of cooling interruption without compromising the primary mist cooling system's efficiency.

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

2Ease of operation

If cooling liquid is sprayed using a pump-driven mist system, then cooling control is improved, but the system requires continuous power supply which creates vulnerability during power outages

Engineering Contradiction:
Improvecooling rate controlVSAvoidpower supply dependency
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The invention makes the power supply system multi-functional by incorporating both normal power supply for regular operation and emergency power supply for failure conditions. This universal power supply architecture allows the system to maintain cooling control capability across different operational states, reducing vulnerability to power outages while preserving ease of operation.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Loss of energy

If the cooling system stops during power failure, then energy consumption is reduced, but temperature and pressure rise causing potential damage to the apparatus

Engineering Contradiction:
Improveenergy saving during power failureVSAvoidtemperature and pressure damage
Core Design Contradiction:
Loss of energyVSObject-affected harmful factors

Solution Approach 1:

The invention introduces an intermediary emergency power supply system that acts as a bridge during power failures. This intermediary power source (generator or backup battery) provides just enough energy to maintain critical cooling function, balancing energy conservation with prevention of temperature and pressure damage to the apparatus.

Inventive Principle:
Principle #24Intermediary (Mediator)
