Cohesive Nail Wrap Retainer for Gel Coating Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The removal of gel-based nail coatings is cumbersome and time-consuming, requiring acetone contact for 10 minutes and often necessitating manual scraping, especially when used on toes, due to the lack of efficient tools for this purpose.
Innovation Solution
A nail coating removal wrap and retainer with a cohesive, latex-free non-woven wrap strip and a solvent pad that allows for secure placement without additional adhesives, enabling hands or feet to move freely during the removal process, using ultrasonic welding for solvent pad attachment to ensure effective solvent contact and minimize solvent exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a finger wrap is used for the soak-off process, then solvent contact is maintained, but the device becomes cumbersome when used on fingers and nearly impossible to use on toes
Solution Approach 1:
The device is divided into separate components: a removable solvent-impregnated pad and a retainer. This segmentation allows the pad to be easily removed and reapplied, making the device adaptable for both finger and toe use without the cumbersome constraints of a continuous wrap design.
Solution Approach 2:
The retainer is designed to be flexible and adaptable, allowing it to conform to different body parts (fingers or toes). The dynamic nature of the retainer enables it to maintain solvent contact while accommodating the anatomical differences between fingers and toes, improving ease of operation.
2Reliability
If acetone is in contact with the nail plate for 10 minutes, then gel polish removal is effective, but the process becomes time-consuming
Solution Approach 1:
The solvent is pre-impregnated into the pad at an optimal concentration and amount before use. This preliminary preparation ensures that when the pad is applied to the nail, the solvent is already in the correct state to effectively dissolve the gel polish, reducing the required contact time from 10 minutes to a shorter duration while maintaining removal effectiveness.
Solution Approach 2:
The invention optimizes parameters such as solvent concentration, pad material porosity, and contact pressure to enhance solvent delivery efficiency. By changing these parameters, the system achieves effective gel polish removal in less time, directly addressing the time-loss contradiction.
3Reliability
If additional adhesives are used to secure the solvent pad, then the pad stays in place, but the device complexity increases
Solution Approach 1:
The retainer is designed to hold the solvent pad through its inherent structure and flexibility, eliminating the need for additional adhesives. The retainer's design allows it to naturally secure the pad in place through mechanical retention, simplifying the device by removing the adhesive component and reducing overall complexity.
4Ease of operation
If the wrap is made cohesive and latex-free, then ease of application is improved, but manufacturing precision requirements increase
Solution Approach 1:
Traditional adhesive bonding is replaced with ultrasonic welding to attach the solvent pad to the retainer. This substitution eliminates the need for adhesives and provides a more precise, controlled bonding method. Ultrasonic welding allows for accurate attachment while maintaining the cohesive and latex-free properties of the wrap, balancing ease of application with manufacturing precision requirements.

AI summary
A nail coating removal wrap and retainer for securing a solvent pad to the digit of a user of a durable nail coating so that a solvent held by the pad is retained in contact with the nail coating to be removed. The nail coating removal wrap and retainer includes a wrap strip to which the solvent pad is bonded in a method impervious to the solvent held by the solvent pad. The wrap strip is selected or treated so that the wrap coheres to itself when wrapped around a digit of the user to releasably secure the wrap to the digit of the user while the solvent works to loosen the nail coating.
