Disposable Adhesive Foot Pad for Dancers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dancers and other performers face injuries and aesthetic issues due to the lack of effective, affordable, and invisible foot protection during performances, as existing solutions are either expensive, visible, or cause blisters from straps.
Innovation Solution
A disposable, adhesive foot pad made of non-woven polyester with a main body shaped like the ball of the foot and locating tabs for precise placement, using a 3M™ spunlace material with a hi-tack adhesive, allowing for easy application and removal without visible straps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If disposable foot protectors are used, then foot protection is provided, but cost increases for recreational dancers
Solution Approach 1:
The patent applies the disposable principle by designing a foot pad that can be easily applied and removed, with an adhesive system that allows for clean removal without residue. The pad is intended for single-use or limited-use scenarios where the low cost of the pad itself enables dancers to use it only when needed without concern for cleaning or reuse, thus providing reliable protection while maintaining affordability for recreational dancers.
2Reliability
If foot protectors are discarded after one use, then hygiene is maintained, but cost increases
Solution Approach 1:
The patent enables a disposable hygiene model by making the foot pad inexpensive enough that dancers can afford to use it once and discard it. The adhesive system is designed to provide strong initial adhesion for protection during use, then allow clean removal without damaging the skin or leaving harmful residue, maintaining hygiene while keeping costs low through the use of affordable materials and simple construction.
3Reliability
If traditional foot protectors are used, then foot protection is provided, but they are visible during performance
Solution Approach 1:
The patent applies local quality by positioning the adhesive specifically on the ball of the foot rather than covering the entire foot. This localized approach provides protection exactly where needed (the ball of the foot which contacts the floor during dance movements) while leaving the rest of the foot exposed and natural-looking, thus maintaining aesthetic value during performance while still providing reliable foot protection.
Solution Approach 2:
The patent extracts only the essential protective function from traditional foot protectors. Instead of using a full-coverage shoe or sock, the invention isolates the adhesive protective layer to just the ball of the foot, removing unnecessary material and structure that would be visible during performance, while retaining the core protective function against friction and impact.
4Reliability
If straps are used to secure foot protectors, then protection is provided, but straps cause blisters
Solution Approach 1:
The patent removes the straps entirely from the design, extracting only the adhesive-based attachment mechanism. The adhesive is formulated to provide sufficient holding power through chemical adhesion to the skin, eliminating the need for mechanical fasteners like straps that create pressure points and cause blisters. This extraction of the harmful strap element while retaining the protective function resolves the contradiction between secure protection and avoidance of strap-induced blisters.

Function Achieved in This Case
Provides effective foot protection that is inexpensive, invisible during performance, and reduces the risk of injuries like blisters and calluses, while being easy to apply and dispose of, suitable for dancers, gymnasts, and martial artists.
Implementation Method 1
an adhesive on one surface of the sheet for adhering the sheet to the foot

AI summary
A protective foot pad includes a sheet of protective material having a main body portion in the shape of the ball of a human foot and a locating tab extending from the main body portion for location between the first and second toes of the foot, an adhesive on one surface of the sheet for adhering the sheet to the foot, and a removable release liner covering the adhesive until the pad is to be adhered to the foot. The pad is especially suited for protecting the bare foot of a dancer, who will use the pad by removing the release liner to expose the adhesive, placing the exposed adhesive on the bottom of his or her foot to cover at least a portion of the ball of the foot, with the tab extending between the first and second toes, and bending the locating tab over the skin between the first and second toes. The main body portion can include one or more lateral extensions that adhere to the side of the foot. In one embodiment, the adhesive is a layer of material that is adhesive on both surfaces thereof, one of which has the releasable liner thereon. The other surface of the layer of material is disposed on an adhesive surface of the sheet, which is a non-woven, open-matrix, polyester layer.
