Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional nail deformity correction devices are used, then correction function is provided, but mounting difficulty increases due to deformed nail shape
Solution Approach 1:
The auxiliary device performs preliminary action by straightening the deformed nail before the correction device is mounted. The straightening unit applies force to gradually straighten the curved nail, creating a suitable shape for subsequent correction device installation, thereby eliminating the need for forcible insertion with tweezers
Solution Approach 2:
The auxiliary device acts as an intermediary between the user and the correction device during mounting. It provides a guided insertion path through the guide groove and positions the correction device accurately on the nail, simplifying the mounting process for unaccustomed users
2Reliability
If conventional correction devices with clip shape are used, then correction function is provided, but close contact with nail is insufficient
Solution Approach 1:
The correction device is designed with a curved shape that matches the natural curvature of the nail surface, replacing the conventional clip shape. This curved design allows the device to conform closely to the nail surface, ensuring maximum contact area and effective correction without unnecessary pressure points
Solution Approach 2:
The correction device features locally optimized contact surfaces with varying curvature radii to match different regions of the nail. The device maintains appropriate thickness distribution, being thinner at contact points to ensure close contact while maintaining structural integrity for correction function
3Strength
If shape-memory alloy is used for elasticity, then correction function is provided, but temperature sensitivity causes excessive or insufficient elasticity
Solution Approach 1:
The patent changes the material parameter from shape-memory alloy to elastic body material with temperature-insensitive elastic properties. This material selection ensures that the correction device maintains consistent elasticity across varying body temperatures, preventing both excessive pressure and rapid elasticity loss
Solution Approach 2:
The correction device is designed as a disposable product made from cost-effective elastic body materials rather than expensive shape-memory alloys. This approach eliminates temperature sensitivity issues while providing sufficient correction function for the intended usage period, and allows for easy replacement if needed

AI summary
There are provided an auxiliary device for mounting nail deformity correction device and a nail deformity correction device mounted on a nail by the same. The auxiliary device includes a resilient block that is placed in parallel with a finger and toe nail in a longitudinal direction of the finger and toe nail, and has elasticity to be elastically contracted and restored in a width direction of the finger and toe nail, and a pair of parallel protrusions that protrudes from an end of the resilient block to be inserted into an inside of the finger and toe nail, and is spaced apart from each other at a predetermined distance in the width direction of the finger and toe nail.
