Artificial Nail Form with Segmented Sizing and Universal Finger Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for making artificial nails are limited to producing nails up to 3 cm in length, lack a standard for sizes and tolerances, and struggle to create extra-large sizes due to deformation issues when using synthetic materials, and do not accommodate the thumb or provide uniformity in nail design.
Innovation Solution
A device featuring a semi-rectangular sheet with symmetrical cutaways and flaps, a removable cover, and an engraved template with size guidelines, allowing for the creation of extra-long nails and accommodating different finger sizes, including the thumb, by applying synthetic resin and using flaps for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If flexible sheets with self-adhesive material are used to make artificial nails, then the device is easy to apply and remove, but the nails are limited to a maximum length of 3 cm and cannot be used for extra-large sizes
Solution Approach 1:
The device is divided into multiple separate forms of different sizes (small, medium, large, extra large) that can be selected based on the desired nail length. Each form is a complete unit with its own adhesive properties, allowing the user to choose the appropriate size without being limited by a single form's dimensions.
Solution Approach 2:
The device provides a universal solution by including multiple forms that can accommodate all five fingers including the thumb, with each form designed to work independently while maintaining the same ease of application and removal characteristics. This multi-size approach allows one device system to serve all nail length requirements.
2Length of moving object
If two or more forms are overlapped to create extra-large nails, then larger nail sizes can be achieved, but the forms become deformed due to excessive weight from plastic resin and do not adhere properly to the finger
Solution Approach 1:
Instead of overlapping multiple forms, the invention provides separately sized forms (small, medium, large, extra large) that are each structurally sound on their own. The extra large form is designed as a complete unit with sufficient adhesive area and structural integrity to support the required nail length without needing to be combined with other forms.
Solution Approach 2:
The forms are designed with varying dimensions and adhesive surface areas optimized for different nail lengths. The extra large form has increased adhesive surface area and structural parameters specifically calibrated to support longer nails and greater resin weight without deformation or poor adhesion.
3Length of moving object
If overlapped forms are used to achieve larger surface area, then extra-large nail sizes can be produced, but the forms do not make a uniform smooth surface and are improperly positioned depending on operator skill
Solution Approach 1:
The invention provides pre-sized forms with predetermined dimensions and shapes optimized for different nail lengths. Each form includes built-in positioning features and guidelines that ensure proper placement on the finger without requiring operator skill for alignment, eliminating the positioning and surface uniformity problems associated with overlapping forms.
Solution Approach 2:
The forms are pre-designed with built-in positioning features, alignment guides, and optimal adhesive placement patterns that ensure correct positioning before the nail-making process begins. This preliminary design of positioning features eliminates the need for operator skill in alignment and ensures uniform surface quality.
4Ease of manufacture
If existing forms are used for artificial nails, then the basic shaping function is achieved, but there is no standard for regulating sizes and tolerances of artificial nail length
Solution Approach 1:
The device provides a universal sizing system with multiple forms labeled by size (small, medium, large, extra large) that correspond to specific length ranges. This standardized sizing system allows manufacturers and users to select appropriate forms based on desired nail length specifications, establishing de facto standards for artificial nail sizes and tolerances.
Solution Approach 2:
Each form is designed with specific dimensional parameters and tolerances optimized for its size category. The forms include engraved templates with size guidelines that define precise length, width, and curvature parameters, establishing standardized dimensions and tolerances for different nail sizes.
5Adaptability or versatility
If existing devices are used, then basic nail shaping is possible, but they cannot accommodate the thumb or provide extra-long and super-extra-long nail sizes
Solution Approach 1:
The device set includes multiple forms specifically designed to accommodate all five fingers including the thumb, with each form optimized for its intended finger. The forms come in size ranges that cover extra-long and super-extra-long nail lengths, providing universal applicability across different finger types and length requirements.
Solution Approach 2:
The invention provides separately designed forms for different fingers, including a specific form for the thumb that accounts for its unique anatomy. Each form is segmented by size category (small, medium, large, extra large) with each category capable of producing extended length nails, thereby expanding the overall length range beyond what single forms can achieve.
