Skin Patch Laminate With Peelable Heat Layer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional skin patches with integrated disposable heating pads require separate application and removal of the heating pad, making it inconvenient to maintain therapeutic effects after the exothermic effects disappear, as the entire patch needs to be replaced or peeled off, including the medicated layer.
Innovation Solution
A skin patch laminate body with a peelable adhesive layer that separates the heat imparting body from the skin patch body, allowing the heat imparting body to be easily peeled off after heat generation while the skin patch remains applied, utilizing a breathable exothermic agent-accommodating layer and a skin adhesive layer with adjustable adhesive strength to maintain therapeutic efficacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the heat imparting body and skin patch body are integrated as a single unit, then the application process is simplified, but the skin patch cannot be reused after the heating pad is consumed
Solution Approach 1:
The invention divides the skin patch into two separable components: a heat imparting body and a skin patch body, connected by a peelable adhesive layer. This segmentation allows the heat imparting body to be removed and replaced while keeping the skin patch body on the skin, enabling reuse of the medicated portion and extending therapeutic duration.
2Reliability
If the entire skin patch is replaced after heat generation, then a fresh heating pad is provided, but the medicated layer is wasted and must be reapplied
Solution Approach 1:
The invention extracts the heat imparting body as a separate, replaceable component from the skin patch system. The peelable adhesive layer enables selective removal of only the heat imparting body while leaving the skin patch body with its medicated layer intact on the skin, preventing waste of the medicated substance.
3Stability of the object's composition
If a strong adhesive is used to attach the heating pad to the skin patch, then the heating pad stays in place during use, but it cannot be easily peeled off after heat generation
Solution Approach 1:
The invention uses a peelable adhesive layer with specifically controlled adhesive properties that provide sufficient initial bonding strength to keep the heat imparting body in place during use, but allow easy peeling after heat generation. The adhesive strength parameter is optimized to balance these opposing requirements.
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
Enables convenient and efficient use of the skin patch by allowing the heat imparting body to be removed without disturbing the skin patch, extending the therapeutic duration and maintaining the medicated layer's effectiveness on the skin.
Implementation Method 1
a heat imparting body including an exothermic agent and an exothermic agent-accommodating layer that accommodates the exothermic agent
