Convertible Upper Wear Neckline Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The shape of the neckline in upper wear, such as crew neck and V neck, restricts wear coordination variations, particularly when a down vest is used as innerwear under a coat with a large neckline.
Innovation Solution
The upper wear design allows the front panel pieces to be folded back and locked onto the back surface, enabling a change in neckline shape from crew neck to V neck through interlocking mechanisms like snap buttons and string-like members, which also prevents wrinkling and easy engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the neckline shape is fixed (crew neck or V neck), then the manufacturing simplicity is maintained, but the wear coordination versatility is restricted
Solution Approach 1:
The neckline configuration is made dynamic by allowing the front panel upper parts to be movable between folded-back and unfolded states. The interlocking mechanism enables the user to switch between different neckline shapes (crew neck when unfolded, V neck when folded back), transforming a static structure into a dynamic one that adapts to different wear coordination needs.
Solution Approach 2:
The front panel is segmented into upper parts and lower parts, with the upper parts being separable through folding and interlocking. This segmentation allows the upper parts to be independently positioned - either folded back to create a V neck or unfolded to maintain a crew neck - providing versatility without requiring complete structural redesign.
2Adaptability or versatility
If the front panel upper parts are folded back to change neckline shape, then the wear coordination versatility increases, but wrinkling of the front panel occurs
Solution Approach 1:
A soft filler material is introduced as an intermediary element between the front panel upper parts and the back surface. This filler serves multiple functions: it maintains the folded-back configuration to achieve V neck shape, prevents direct contact that would cause wrinkling, and provides comfort against the skin. The intermediary resolves the conflict between achieving neckline versatility and preventing fabric damage.
3Reliability
If interlocking members are provided at the back surface, then the folded-back portion is securely held, but the device complexity increases
Solution Approach 1:
The interlocking mechanism is designed to be self-servicing through simple snap buttons that automatically engage when the front panel upper parts are folded back. The snap buttons on the front panel upper parts interlock with corresponding snap buttons on the back surface, creating a self-securing system that requires minimal additional components while ensuring reliable holding of the folded configuration.

AI summary
Provided is an upper wear allowing an increase in variations of wear coordination of the upper wear. An upper wear 1 includes a front panel 10 having front panel pieces 50 and 51 at left and right. The upper wear 1 is configured such that respective upper parts of the left and right front panel pieces 50 and 51 can be folded back to the back surface sides thereof, to be held at the back surfaces of the front panel pieces 50 and 51, respectively.
