Filter Fixing Module for Dual-Compatible Medical Cooling Handpiece
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cooling devices for skin treatment are not compatible with both hose-connected refrigerant tanks and refrigerant cartridges, posing safety risks due to the potential delivery of impurities to the skin, which can cause infections.
Innovation Solution
A filter fixing module is integrated into the cooling device, featuring a body with a support surface and a grip unit, allowing easy mounting and removal, which filters out impurities from the refrigerant and includes a perforating member to connect with both cartridge and tank systems, ensuring safe and effective cooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional cooling device uses either a hose-connected refrigerant tank or a refrigerant cartridge, then the device can perform cooling treatment, but the device cannot be compatible with both types of refrigerant supply units simultaneously
Solution Approach 1:
The cooling device is designed with a universal coupling member that can connect to both hose-connected refrigerant tanks and refrigerant cartridges. The coupling member includes a through hole that accommodates either a hose or a cartridge, allowing the same cooling device to work with multiple types of refrigerant supply units without requiring different device structures.
2Productivity
If the cooling device delivers refrigerant directly to the skin without filtration, then the cooling treatment can be performed, but impurities in the refrigerant may cause skin infection
Solution Approach 1:
A filter is installed in advance within the refrigerant flow path, specifically in the coupling member between the refrigerant supply unit and the cooling device. The filter pre-cleans the refrigerant by removing impurities before the refrigerant reaches the skin through the nozzle, ensuring safe cooling treatment without compromising treatment efficiency.
3Reliability
If the filter is permanently fixed in the cooling device, then impurity filtration is ensured, but the device becomes difficult to maintain and repair
Solution Approach 1:
The filter is designed as a separate, removable component that can be easily detached from the coupling member. This segmentation allows the filter to remain permanently installed for continuous filtration effectiveness while enabling simple removal and replacement for maintenance, improving both reliability and ease of repair.
4Ease of repair
If the cooling device includes a removable filter fixing module, then ease of maintenance is improved, but the device structure becomes more complex
Solution Approach 1:
The filter fixing module incorporates a dynamic locking mechanism that can be easily engaged and disengaged. The module includes a locking member that secures the filter in place during operation but can be released with simple user action, providing stable filtration during use while enabling easy removal for maintenance without excessive structural complexity.
