Breathable Polyurethane Skin Appliqué for Lost Person Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional temporary tattoos for identification are semi-translucent, difficult to read on dark skin, not durable enough, and pose a risk of ink absorption through the skin, making them unsuitable for environments like water parks and beaches.
Innovation Solution
A safety skin appliqué kit using pre-printed, breathable polyurethane tape with a hypoallergenic acrylate adhesive and digital non-toxic ink, providing a brightly contrasting background for custom contact information that can be easily applied and lasts for weeks, even in aquatic environments, without ink leaching through the skin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional temporary tattoos are used for identification, then they can be applied to skin, but they are semi-translucent and difficult to read on dark skin
Solution Approach 1:
The patent applies a bright white or light-colored background layer to the skin appliqué, creating high contrast with dark text. This color strategy ensures that contact information is clearly visible on all skin tones, particularly solving the problem of readability on dark skin where semi-translucent tattoos fail.
2Duration of action of stationary object
If conventional temporary tattoos are used, then they provide identification, but they are not durable enough and can be easily removed
Solution Approach 1:
The patent changes the physical state and adhesive properties of the skin appliqué by using a pressure-sensitive adhesive backing instead of traditional tattoo ink. This allows the appliqué to be firmly attached to the skin and withstand water, friction, and time, while still being removable when needed, thus achieving both durability and reliability.
3Loss of information
If conventional temporary tattoos with ink are used, then they can display information, but there is a risk of ink absorption through the skin
Solution Approach 1:
The patent introduces a non-toxic polymer or vinyl layer as an intermediary between the information display and the skin. This barrier layer prevents any potential ink or chemical absorption through the skin while still allowing the contact information to be clearly displayed and readable, thus eliminating the harmful effect while preserving the information function.
4Manufacturing precision
If contact information is written directly on skin with ink, then it provides identification, but it is difficult to do with accuracy and lacks color contrast
Solution Approach 1:
The patent pre-prints the contact information, plea for help, and design elements on the skin appliqué before application to the skin. This preliminary action ensures accurate placement, proper sizing, and high-contrast coloring without requiring manual drawing on the child's skin, thus solving both the precision and visibility problems.

AI summary
A safety skin appliqué kit for parents and custodians of children, disabled persons, and the elderly, including a marking pen and a pre-packaged collection of preprinted skin appliqués each removably sandwiched between two carrier sheets. Each of the appliqués further comprise a die cut section of breathable polyurethane tape, printed with a forward image on one side defined by a lightly-colored high-contrast window, and pre-printed plea to call if lost. The appliqués are coated with hypoallergenic acrylate adhesive for application to skin or other surfaces. Parents and custodians can apply one of said appliques' to their child, disabled person, or elderly charge, and write a contact telephone number in the window of the appliqué. This way, if their charge becomes lost, passersby will notice the appliqué, read the contact telephone number, and call the custodian.
