Top-of-Foot Covering with UV-Blocking Fabric and Elastic Bands
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The top of the foot is often overlooked when applying SPF lotion during outdoor activities, leading to increased concerns about skin cancer due to sun exposure, as existing solutions do not effectively provide sun protection in this area while maintaining comfort and openness.
Innovation Solution
A top-of-foot covering made from UV-blocking fabric, such as polyester with LYCRA, that secures to the foot using elastic bands, allowing for wear with or without shoes, providing sun protection without covering the sole and maintaining breathability and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a top-of-foot covering is used to provide sun protection, then UV protection is improved, but comfort and breathability may deteriorate
Solution Approach 1:
The patent uses a thin, flexible fabric material that provides UV protection while remaining comfortable and breathable. The fabric is designed to be lightweight and conform to the foot's shape, ensuring protection without compromising comfort during outdoor activities.
Solution Approach 2:
The covering is designed to protect only the specific area of the top of the foot that requires UV protection, rather than covering the entire foot. This localized approach provides necessary protection while maintaining breathability and comfort in other areas.
2Object-affected harmful factors
If a top-of-foot covering is used to provide sun protection, then UV protection is improved, but the device complexity increases
Solution Approach 1:
The foot covering is divided into separate functional components: a main body portion that covers the top of the foot, and elastic bands that secure it in place. This segmentation allows each component to be optimized independently while keeping the overall structure simple and effective.
Solution Approach 2:
The elastic bands serve multiple functions: they secure the covering to the foot, provide adjustability for different foot sizes, and ensure the covering stays in place during movement. This multi-functionality reduces the need for additional components, simplifying the overall design.
3Reliability
If elastic bands are used to secure the covering, then retention is improved, but the device complexity increases
Solution Approach 1:
The elastic bands are designed to automatically adjust and secure the covering to the foot without requiring additional fasteners, buckles, or complex adjustment mechanisms. The elasticity provides self-regulating tension that ensures reliable retention while maintaining simplicity in the securing mechanism.

AI summary
A top of foot covering provides sun protection for the top of a wearer's foot and may be used when the wearer is barefoot or when wearing flip flops, sandals or shoes. The top of foot covering includes a covering, such as a fabric body, which extends over a top of a wearer's foot. The top of foot covering may be secured to the wearer's foot by one or more straps, such as toe and/or ankle straps.
