Dyed Polymer Layer Camouflaging Electronic Components
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Body-mountable devices, such as eye-mountable contact lenses, with electronic structures containing metallic components are aesthetically undesirable due to visibility concerns, and existing solutions do not effectively camouflage these components.
Innovation Solution
A dyed polymer layer is applied over the electronic structure, specifically designed to cover and obscure metallic components, blending with the user's eye color to reduce visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If electronic components are embedded in a transparent polymer, then the device maintains aesthetic appearance, but the metallic components remain visible and aesthetically undesirable
Solution Approach 1:
The patent applies a dyed polymer layer with color matching the user's eye color (e.g., brown, blue, green) over the transparent polymer and electronic components. This coloration camouflages the metallic components by blending them with the natural eye color, making the device less visible and aesthetically acceptable while maintaining the overall transparency of the contact lens structure.
Solution Approach 2:
The patent creates a multi-layer composite structure consisting of a transparent polymer layer embedded with electronic components, covered by a dyed polymer layer. This composite structure combines the optical clarity of transparent materials with the aesthetic benefits of color-matched materials, achieving both functionality and cosmetic acceptance.
2Object-affected harmful factors
If a dyed polymer layer is applied to camouflage electronic components, then visibility is reduced, but the layer must maintain biocompatibility and optical properties
Solution Approach 1:
The patent carefully controls the optical parameters of the dyed polymer layer, including its thickness, dye concentration, and color spectrum, to achieve optimal camouflage while maintaining biocompatibility and optical functionality. The layer is designed to be sufficiently thin and optically compatible to avoid interfering with the contact lens's primary functions of vision correction and oxygen permeability.
