Solution Overview

Problem

Existing nail-biting and finger sucking treatments are not customizable to individual taste preferences, leading to inconsistent effectiveness and reliance on bitterness levels that may be too low for many users.

Innovation Solution

A customizable treatment kit with a base solution and an additive solution, allowing users to adjust bitterness levels by adding the additive to the base solution, comprising butyl acetate, ethyl acetate, denatonium benzoate, nitrocellulose, n-butyl alcohol, isopropyl alcohol, and citric acid, with a dropper for precise dosage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed bitterness level treatment is used, then the treatment is simple to manufacture and apply, but it is ineffective for users with varying taste sensitivities

Engineering Contradiction:
Improvecustomizability to individual taste preferencesVSAvoidtreatment composition structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The treatment is divided into two separate components: a base solution containing the primary bittering agent (denatonium benzoate) and an additive solution containing additional bittering agents. Users can mix these components in varying proportions to customize the bitterness level according to their individual taste sensitivity, thereby resolving the contradiction between adaptability and complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The treatment system transitions from a fixed composition to a dynamic, adjustable formulation. The base solution provides a consistent foundation, while the variable addition of additive solution allows users to dynamically adjust the bitterness level to match their personal tolerance, enabling customization without requiring complete reformulation of the entire treatment.

Inventive Principle:
Principle #15Dynamics

2Reliability

If higher bitterness levels are used to ensure effectiveness, then the deterrent effect is stronger, but the flammability and toxicity risks increase

Engineering Contradiction:
Improveeffectiveness of deterrentVSAvoidflammability and toxicity
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system allows adjustment of the concentration parameter of bittering agents through variable mixing ratios of base and additive solutions. Users can optimize the bitterness concentration to achieve effective deterrence while maintaining safety margins against flammability and toxicity thresholds, thus resolving the contradiction between reliability and harmful factors.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The base solution acts as an intermediary carrier that delivers a controlled, safe level of bittering agents. The additive solution serves as an optional enhancement that users can introduce in measured amounts. This intermediary structure allows gradual adjustment of bitterness while maintaining control over the total concentration of active ingredients, preventing excessive flammability and toxicity.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If a single high-bitterness treatment is provided, then maximum deterrent effect is achieved, but it causes discomfort or rejection by users with low bitterness tolerance

Engineering Contradiction:
Improvedeterrent effectivenessVSAvoiduser acceptance and compliance
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The treatment system provides localized adjustment of bitterness intensity to match individual user characteristics. Users with low bitterness tolerance can apply only the base solution or add minimal additive solution, while users with high tolerance can increase the additive proportion. This localized customization ensures that each user receives the appropriate deterrent intensity, improving both effectiveness and acceptance.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system enables dynamic adjustment of treatment strength based on individual user response and tolerance levels. Users can start with lower concentrations and gradually increase the additive proportion as their tolerance develops or as they determine their optimal deterrent level, thereby improving ease of operation and user acceptance while maintaining reliable deterrence.

Inventive Principle:
Principle #15Dynamics

AI summary

The invention relates to a method of customizing a nail-biting and/or finger sucking treatment solution, and a kit for providing a nail-biting and finger sucking treatment that is customizable for a wide range of afflicted users seeking to break a persistent nail-biting and/or finger sucking habit. In exemplary embodiments, the composition kit includes two separate containers, a first container having a nail growth-promoting, waterproofing composition that may be applied directly on a user's nails; and a second container may include an additive for customizing a bitterness factor of the first composition. Typically, the first container includes an applicator such as a brush. To facilitate adding the additive in a manner that is easily customizable, the second container may include a dropper for adding small doses of the additive composition to the first composition. The customizable kit allows the user to safely adjust the bitterness so that the treatment remains effective.
