Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical products fail to provide a simple, well-dosed, and precisely localized application of liquid medical treatment media to skin or tissue areas, often experiencing clogging issues with applicator tips and instability of treatment solutions.
Innovation Solution
A pen-shaped applicator with a porous, sintered material tip and a container system that ensures controlled and metered delivery of treatment media, using oily or aqueous solutions with additives like surfactants and film-forming components, preventing clogging and maintaining solution stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a liquid treatment medium is applied using a conventional applicator tip, then the application process is simple, but the applicator tip becomes clogged and the solution is unstable
Solution Approach 1:
The applicator tip is made of porous material with controlled pore sizes that prevent clogging while maintaining controlled delivery. The porous structure allows the liquid treatment medium to pass through without blocking, solving the clogging issue while preserving application simplicity.
Solution Approach 2:
The patent changes the physical parameters of the applicator tip by selecting specific pore size ranges (e.g., 10-50 μm) and material properties to optimize both flow characteristics and clogging resistance. This parameter optimization enables reliable operation without compromising ease of use.
2Manufacturing precision
If the container interior volume is reduced for single treatment use, then precision and simplicity are improved, but the device becomes more fragile and harder to handle
Solution Approach 1:
The device is segmented into a reusable applicator tip and a disposable container assembly. This segmentation allows the container to be optimized for precision (small volume) while the robust applicator tip provides durability and handling comfort. The separable design enables each component to be optimized independently.
Solution Approach 2:
The applicator tip uses composite construction combining porous material with appropriate mechanical strength properties. This composite approach ensures both the precision required for single-use applications and the durability needed for handling, resolving the contradiction between small size and strength.
3Stability of the object's composition
If an oily solution is used for treatment medium, then flow control and stability are improved, but the solution requires specific additives to prevent clogging
Solution Approach 1:
The porous applicator tip structure works synergistically with oily solutions by providing physical flow control through pore size selection. This reduces the need for complex chemical additives while maintaining solution stability and preventing clogging, as the porous material provides mechanical flow regulation.
Solution Approach 2:
The porous applicator tip acts as an intermediary between the stable oily solution and the treatment area. It mediates the flow characteristics and prevents clogging without requiring the solution itself to contain complex anti-clogging additives, thus simplifying the overall formula while maintaining stability.
