Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional continuous glucose monitoring systems face issues with adhesive tape size requirements that increase applicator size, manufacturing costs, and adhesive force, leading to usability and design limitations.
Innovation Solution
An auxiliary adhesive patch with an over patch and separable release paper that minimizes adhesive tape size, enhances adhesive force, and allows for convenient application, featuring a pressurizing area and adhesive area covered by multiple separable release paper pieces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the adhesive tape size is increased to enhance adhesive force, then the adhesive force is improved, but the applicator size and manufacturing cost increase
Solution Approach 1:
The adhesive system is divided into two independent components: a minimal adhesive tape attached to the housing and an auxiliary adhesive patch separately applied to the skin. This segmentation allows the adhesive tape to remain small while the auxiliary patch provides additional adhesive force, resolving the contradiction between adhesive strength and applicator size.
Solution Approach 2:
The auxiliary adhesive patch is designed to cover and integrate with the adhesive tape, creating a nested adhesive system. The auxiliary patch encompasses the minimal adhesive tape area while providing extended adhesive coverage, enabling enhanced adhesive force without increasing the core applicator size.
2Strength
If the adhesive tape size is increased to enhance adhesive force, then the adhesive force is improved, but the manufacturing cost increases
Solution Approach 1:
By separating the adhesive function into a minimal tape and an auxiliary patch, the housing and applicator can be manufactured at standard sizes, reducing manufacturing costs. The auxiliary patch is applied separately, allowing adhesive force enhancement without increasing core component manufacturing complexity or cost.
3Reliability
If the release paper is attached to the adhesive side of the over patch, then the adhesive side is protected, but the application process becomes complex
Solution Approach 1:
The release paper is divided into multiple separable pieces, each corresponding to different adhesive areas. This segmentation allows users to remove only the necessary release paper portions during application, simplifying the process while maintaining adhesive protection when not in use.
Solution Approach 2:
The release paper pieces are pre-positioned on the auxiliary adhesive patch during manufacturing, protecting the adhesive sides before use. This preliminary protection is automatically removed during the application process, ensuring adhesive integrity while maintaining ease of use.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution maintains adhesive force without enlarging the adhesive tape, reduces manufacturing costs, and improves usability by enabling rapid and convenient application to various shapes and designs.
Implementation Method 1
an adhesive tape arranged to a bottom surface of the housing and outwardly protruding along an outer portion circumference of the housing
Implementation Method 2
a pressurizing area formed along an outer circumference of the penetrating hole and configured to pressurize an area of the adhesive tape
