Garment Back Slit Stitching Template for Symmetrical Vent Seams
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The current stitching process for trench coat back vents requires skilled workers, leading to low efficiency, uneven side lengths, and poor quality due to manual folding and stitching, resulting in unsightly appearances.
Innovation Solution
A garment back slit stitching template with a base plate, foldable cover plates, and multiple stitching channels that guide the folding and stitching of garment pieces, utilizing grip strips and limiting convex strips for precise alignment and stability, allowing for symmetrical stitching through two operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual folding and stitching is used for back vents, then the process can be completed with simple equipment, but the processing efficiency is low and high skill level is required
Solution Approach 1:
The patent introduces a stitching template as an intermediary tool between the worker and the stitching process. The template includes pre-designed guide channels that direct the stitching needle along precise paths, and positioning structures that automatically align the back vent pieces. This intermediary device transfers the complexity from worker skill to the template design, enabling less skilled workers to achieve high-precision stitching efficiently.
Solution Approach 2:
The stitching template is prepared in advance with pre-configured stitching channels, positioning features, and folding guides. The template itself embodies the preliminary design work, so during actual production, workers simply need to place the back vent pieces on the template and follow the guide channels for stitching. This preliminary preparation eliminates the need for workers to perform complex measurements and positioning during the stitching process.
2Manufacturing precision
If manual stitching is used for back vents, then equipment complexity is low, but the stitching quality is poor with uneven side lengths
Solution Approach 1:
The stitching template serves as a precision intermediary that ensures consistent stitching quality. It includes symmetrical guide channels on both sides that guarantee equal stitching paths, positioning features that ensure identical placement of back vent pieces, and folding guides that create uniform folds. This intermediary device transfers the precision requirement from worker skill to the template's physical structure.
Solution Approach 2:
The template design uses asymmetrical positioning features and guide channels that are specifically configured to compensate for natural variations in manual stitching. The left and right sides have mirrored but distinct positioning structures that ensure symmetrical outcomes despite the inherently asymmetrical nature of manual operations. This deliberate asymmetry in the template's design achieves symmetry in the final product.
3Loss of time
If manual folding and stitching is used, then the process is flexible and adaptable, but the time spent on positioning and marking is excessive
Solution Approach 1:
The stitching template has pre-configured all positioning features, stitching channel locations, and folding guide positions during its manufacturing. This preliminary action eliminates the need for workers to perform time-consuming measurements, mark-making, and positioning adjustments during production. Workers simply place the back vent pieces on the template, and the pre-designed features automatically establish correct positions.
Solution Approach 2:
The stitching template is designed as a universal tool that can accommodate different back vent designs and garment types. It includes adjustable positioning features and multiple stitching channel options that can be selected based on the specific design requirements. This universality maintains process flexibility while eliminating the time loss associated with creating new positioning and marking systems for each design.
