Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fastening devices with separate adhesive elements and receiving elements are used, then the wire can be securely received, but the alignment requirements increase and application becomes more difficult
Solution Approach 1:
The patent combines the adhesive element and receiving element into a single integrated fastening device. The receiving element is directly formed as part of the adhesive element structure, eliminating the need for separate components and reducing alignment requirements during application while maintaining secure wire reception.
Solution Approach 2:
The adhesive element serves multiple functions simultaneously: it provides adhesion to the nail surface, forms the receiving structure for the wire, and incorporates manipulation aids for easy handling. This multi-functionality reduces the number of separate components needed and simplifies the application process.
2Manufacturing precision
If filigree dimensions are used for fastening devices, then the wire can be precisely positioned, but insertion difficulties increase
Solution Approach 1:
The fastening device is pre-formed with the receiving element and manipulation aids integrated into the structure before application. The manipulation aids (such as protrusions or handles) are built-in to facilitate easy insertion of the wire without requiring precise manual alignment, while the receiving element maintains precise dimensions for secure wire positioning.
3Reliability
If precise alignment is required during gluing, then the wire can be securely attached, but user skill requirements increase
Solution Approach 1:
The fastening device incorporates asymmetric manipulation aids such as protrusions or handles on specific sides of the adhesive element. These asymmetric features guide the user's fingers or tools during application, naturally orienting the device correctly on the nail surface and eliminating the need for precise manual alignment while ensuring secure wire attachment.
4Reliability
If the fastening device requires complex alignment, then the wire can be securely received, but application time increases
Solution Approach 1:
The integrated fastening device with built-in manipulation aids is designed to be self-aligning during application. The protrusions or handles naturally guide the device into the correct position on the nail, and the receiving element automatically captures the wire without requiring complex manual alignment procedures, thereby significantly reducing application time while maintaining secure wire reception.
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
Facilitates quick, easy, and secure attachment of nail correction wires, reducing user skill requirements and ensuring comfortable application, even for inexperienced users, while allowing flexibility in wire placement and repeated use.
Implementation Method 1
an adhesive element (1) which is firmly connected to a receiving element (3)
Implementation Method 2
The pain is significantly reduced and healing is made possible. Nail correction braces have proven to be very efficient, the effect of which is based on the restoring forces of spring elements
