Notched Collar Snaps Prevent Curling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing collar technologies, such as those described in U.S. Pat. No. 4,202,054, face issues with curled up edges at notches when worn in an outer open 'continental style' under a jacket, leading to bulky crests or wrinkling, and no known solutions have effectively addressed this problem while maintaining aesthetic appeal.
Innovation Solution
The implementation of fastening means, including snaps, buttons, zippers, or hook-and-loop type fasteners, positioned on both sides of the collar, with one member on the inner surface of the back collar and the other on the outer collar band, to prevent the slit borders from curling up from the shirt surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If slits are extended from the free marginal edge of the collar to allow independent movement of collar wings, then the collar can be worn in an open continental style under a jacket without bulky crests or wrinkling, but the slit borders curl up from the shirt surface creating aesthetic issues
Solution Approach 1:
The patent applies preliminary action by pre-positioning fastening means (snaps, buttons, or other fasteners) at the slit borders before the collar is worn. These fasteners are strategically placed to hold the slit borders in their proper position against the shirt surface, preventing the curling issue from occurring in the first place when the collar is worn in an open continental style.
Solution Approach 2:
The patent changes the physical state of the slit border by introducing fastening means that alter the border's position and orientation parameters. The fasteners modify the boundary conditions of the slit border, transforming it from a free-moving edge that curls to a constrained edge that remains flat against the shirt surface.
2Shape
If fastening means are added to prevent slit border curling, then the aesthetic appearance is improved, but the collar structure becomes more complex
Solution Approach 1:
The patent applies local quality by adding fastening means only at specific locations where needed - at the slit borders where curling occurs - rather than throughout the entire collar structure. This localized approach addresses the aesthetic issue while minimizing the increase in overall structural complexity.
Solution Approach 2:
The patent employs simple, inexpensive fastening elements such as snaps, buttons, or small clips that are easy to attach and remove. These temporary fasteners provide the necessary structural support to prevent curling without creating permanent complexity in the collar design, and can be easily replaced or adjusted as needed.

AI summary
A pair of notches or slits in a collar can prevent the formation of bulky crests or wrinkling when the collar is arranged in an outer open ‘continental style’ under a jacket, however there is also a propensity for such a collar to curl up at the notches. The invention herein discloses the use of a fastening means to prevent the slit borders, forming the edge surfaces of each back section of the collar, from curling up from the shirt surface. The fastener means are located on each side of the collar, such that one member is located on the inner surface of the back collar where the outside edge meets the base of the slit edge and the other member is located on the outer surface of the collar band.
