Placket Stiffener Arrangement for Garment Collar Buckling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Garment collars with open upper areas tend to crumple or buckle under weight, leading to an unattractive appearance, and starch-based stiffening solutions are temporary and uncomfortable.
Innovation Solution
Integration of button-side and buttonhole-side stiffener members within the garment fabric, featuring anti-roll tabs and outwardly flared portions to maintain the upper areas upright, constructed from materials like polypropylene for durability and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If starch is used to stiffen portions of the shirt, then the open upper areas are maintained apart, but the effects dissipate over time and the garment becomes uncomfortable
Solution Approach 1:
The patent extracts the stiffening function from temporary starch applications and implements it through permanent plastic stiffener members embedded in the placket. These stiffener members (22, 24) are integrated into the garment structure during manufacturing, providing lasting support without requiring repeated starch applications that cause discomfort.
Solution Approach 2:
The patent replaces temporary, short-lived starch stiffening with durable, long-lasting plastic stiffener members. The stiffener members are designed to maintain their stiffening properties through multiple wash cycles and extended wear, eliminating the need for frequent reapplication of starch.
2Shape
If the upper buttons or snaps are left unfastened to provide an open collar appearance, then the collar can breathe and look stylish, but the open upper area crumples or buckles under the weight of the collar
Solution Approach 1:
The patent segments the placket structure by inserting separate stiffener members (22, 24) between the button-side placket and buttonhole-side placket. This segmentation allows the placket to maintain its overall structure while the stiffener members provide localized support to prevent crumpling, enabling the open collar appearance to be maintained without sacrificing stability.
Solution Approach 2:
The patent creates a composite structure by combining fabric placket layers with plastic stiffener members. The stiffener members are embedded within the placket assembly, creating a layered composite that provides both the flexibility needed for open collar styling and the structural support needed to prevent buckling under collar weight.

AI summary
A garment, such as a shirt, adapted to be worn on the upper body of a user includes a pair of adjacent front panels. Each panel terminates in an edge area and defines an upper neck area positioned in front of the neck of the user when the garment is worn. A closed passage is provided in each front panel adjacent the edge area of the front panel, and extends downwardly from the upper edge area of the front panel. A stiffener member is contained within each passage, and extends into the upper neck area of the front panel and downwardly therefrom within the closed passage so as not to be removable from within the passage. The stiffener members are configured and arranged so as to maintain the upper neck areas of the adjacent front panels apart from each other when the garment is worn.
