Partially False Button Closure Shirt Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fully openable button front shirts often experience undesirable gaps between buttons, which can reveal undergarments or skin, and existing solutions like closely spaced buttons or additional fasteners are impractical for regular wear.
Innovation Solution
A shirt design featuring a partially false button closure, where the rear placket is only visually closed by false buttons, maintaining the appearance of a fully openable front while preventing gaps, with a concealed rear or side closure for easy donning and doffing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If buttons are placed exceptionally close together to minimize gapping, then gapping between buttons is reduced, but the number of buttons required increases making the shirt tedious and difficult to fasten
Solution Approach 1:
The shirt front is segmented into two distinct zones: an upper openable portion with functional buttons and buttonholes, and a lower false portion with decorative buttons only. This segmentation allows the shirt to achieve a gap-free appearance throughout while requiring buttons to be fastened only in the upper portion, dramatically reducing the number of fastening operations needed.
Solution Approach 2:
The false lower placket copies the visual appearance of the functional upper placket, including decorative buttons that mimic real buttons. This copying creates the illusion of a fully buttoned front without the functional complexity, achieving the desired aesthetic without the operational burden of numerous fasteners.
2Object-affected harmful factors
If additional fasteners such as two-sided tape or hook and loop material are used to prevent gapping, then gapping is eliminated, but the complexity of the shirt construction increases
Solution Approach 1:
The placket is divided into functional and decorative zones, eliminating the need for additional fastening materials. The false placket uses only decorative buttons attached with standard stitching, avoiding the complexity of incorporating tapes, adhesives, or hook-and-loop materials while still achieving a gap-free appearance.
3Ease of operation
If buttons are spaced further apart for comfort, then ease of buttoning improves, but gapping increases causing undergarments or skin to become visible
Solution Approach 1:
By segmenting the button placement into functional upper buttons with appropriate spacing for ease of fastening, and decorative lower buttons that fill the visual gap, the design allows comfortable spacing in the operational zone while maintaining continuous visual coverage throughout the entire shirt front.
Solution Approach 2:
The decorative buttons on the false placket copy the appearance and spacing pattern of functional buttons, creating a visually continuous button line that prevents gapping without requiring actual fasteners at every interval, thus maintaining ease of operation.

AI summary
The shirt includes a vertically extending front placket and a vertically extending rear placket which are selectively attachable together through buttons on the rear placket and buttonholes in corresponding positions through the front placket. The front placket and rear placket extend down from a neck opening to a junction. A false placket extends down from the junction. The false placket has appearance characteristics matching that of the front placket and is continuous with the front placket. Buttons on the false placket match buttons on the rear placket. The false placket thus appears as though it is a continuation of the buttoned front placket and rear placket. However, the false placket his unopenable. An additional closure is preferably provided, either in the form of a rear closure or a side closure. This additional closure can be fitted with a zipper or other fastener for selectively closing and opening this additional closure.
