Solution Overview

Problem

Conventional cooling devices using coolant spray methods suffer from coolant leakage both during operation and when stopped, posing safety risks due to potential skin infections from impurities in the coolant.

Innovation Solution

A filter module with a unique shape and sealing members is introduced, comprising a filter accommodation member, a first sealing member, and a second sealing member, designed to minimize coolant leakage by ensuring a contact surface with the support surface and incorporating a filter that filters out impurities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional coolant spray method is used, then cooling effect is achieved, but coolant leakage occurs both during operation and when stopped

Engineering Contradiction:
Improvecoolant leakage preventionVSAvoidoperation simplicity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The sealing member is pre-installed in the filter accommodation member before the coolant storage unit is attached. This preliminary sealing arrangement ensures that when the coolant storage unit is connected, the sealing interface is already in place, preventing leakage both during operation and when stopped, without requiring complex additional sealing mechanisms

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The sealing member acts as an intermediary element between the filter accommodation member and the coolant storage unit. This intermediate sealing component creates a sealed connection that prevents coolant leakage while maintaining the simplicity of the overall assembly operation

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If coolant is sprayed onto treatment areas, then cooling treatment is provided, but impurities in the coolant may be transferred to the skin causing infection

Engineering Contradiction:
Improveskin safetyVSAvoidsystem structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system is segmented into distinct functional components: the coolant storage unit, the filter module with accommodation member and sealing members, and the spray mechanism. This segmentation allows the filter to be positioned specifically between the storage unit and spray mechanism, ensuring impurity removal while maintaining overall system functionality without excessive complexity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The filter serves as an intermediary component between the coolant storage unit and the spray nozzle. It filters out impurities from the coolant before the coolant reaches the treatment area, ensuring skin safety while maintaining a relatively simple system structure through this single intermediate filtering stage

Inventive Principle:
Principle #24Intermediary (Mediator)

3Object-affected harmful factors

If a filter is added to remove impurities, then skin safety is improved, but the device structure becomes more complex

Engineering Contradiction:
Improveimpurity transfer to skinVSAvoidstructure complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The filter is merged with the filter accommodation member as an integrated assembly. The sealing members are also integrated into this assembly, creating a unified filter module that removes impurities while avoiding the need for separate, additional components that would increase structural complexity

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The filter accommodation member serves multiple functions: it houses the filter, provides sealing surfaces through the sealing members, and interfaces with the coolant storage unit. This multi-functionality reduces the need for separate components, thereby reducing overall structural complexity while still achieving impurity removal and leakage prevention

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