Wide-jaw-opening nail clipper with angled blade head
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nail clippers are inconvenient for individuals with arthritis, pregnant women, and obese individuals due to their flat-headed design, which requires wrist bending, and they are not suitable for trimming ingrown toenails or effectively containing nail debris.
Innovation Solution
A wide-jaw-opening nail clipper with a trimming blade head that tilts upward and forward, featuring pointed cone-shaped blades, an internal elastic member for increased durability and reduced manufacturing costs, and an elastic soft sleeve with blocking portions to contain nail debris.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a flat-headed and linear nail clipper design is used, then the structure is simple, but users need to bend their wrists outward which is burdensome and inconvenient
Solution Approach 1:
The nail clipper changes from a flat-headed linear design to an asymmetric angled design where the blade head is tilted at approximately 45 degrees relative to the handle. This asymmetric configuration allows the blade to approach the nail at an optimal angle while the handle remains positioned for comfortable gripping, eliminating the need for users to bend their wrists outward.
2Adaptability or versatility
If a flat-headed and crescent-shaped trimming blade edge is used, then the structure is simple, but it is not suitable for trimming of ingrown toenails
Solution Approach 1:
The blade edge transitions from a uniform flat-headed crescent shape to a differentiated structure with a pointed cone-shaped tip at the leading end and a flat-headed trailing end. The pointed cone-shaped tip provides concentrated cutting capability for penetrating ingrown toenails, while the flat-headed trailing end maintains the original function for general nail trimming, making the single blade structure adaptable to multiple nail types and conditions.
3Length of moving object
If a V-shaped blade holder is used, then the connecting structure is simple, but the width between blade edges is limited
Solution Approach 1:
The integrated V-shaped blade holder is segmented into separate upper and lower blade assemblies, each mounted on independent arms that pivot from common pivot points. This segmentation allows the upper and lower blades to be positioned independently, increasing the vertical distance between them and thus widening the gap between blade edges to accommodate thicker nails while maintaining structural integrity through the shared pivot mechanism.
4Reliability
If a clamping hook structure is used to connect handles, then the assembly is simple, but it can be easily detached during use and cannot withstand forceful pressing
Solution Approach 1:
The separate clamping hook connections on each handle are merged into a unified integrated connection structure where a single reinforced joint mechanism connects both handles to the blade assembly. This integrated connection distributes pressing forces across both handles simultaneously and provides a unified attachment point that prevents detachment during use while maintaining manufacturing simplicity.
5Object-affected harmful factors
If barrier plates are arranged on both sides of two blade edges, then some nail clipping and debris splatter problems are addressed, but complete enclosing and blocking cannot be achieved due to limited width and blade sharpening gaps
Solution Approach 1:
The barrier plates arranged only on the lateral sides are extended into the vertical dimension by adding upper and lower barrier plates that connect to the side barriers, forming a complete three-dimensional enclosed cage around the blade assembly. This multi-dimensional enclosure eliminates gaps at the top and bottom where debris could escape, achieving complete containment while maintaining structural simplicity through the integrated cage design.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design reduces wrist bending during use, facilitates trimming of ingrown nails, enhances durability, reduces manufacturing costs, and effectively minimizes nail debris splatter while allowing for normal trimming and observation of the blades.
Implementation Method 1
an elastic member is installed inside the mounting groove, both ends of the elastic member abut against the first blade head portion and the second blade head portion respectively
