Pocket Attaching Machine Template Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machines for attaching pockets on fabric are not versatile enough to handle different pocket shapes or types of seams, particularly those with narrow openings or critical shapes, making them unreliable and difficult to use.
Innovation Solution
A machine with a template comprising two separate portions that can move transversally to adjust between a minimum and maximum size configuration, allowing for insertion and extraction from pockets with varying widths, and a mechanism to change the template's size to accommodate different pocket shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a template with fixed size is used to attach pockets, then the machine is simple to operate, but it cannot accommodate pockets with varying widths or critical shapes
Solution Approach 1:
The template is divided into two separate portions: a fixed portion and a mobile portion. The mobile portion can move transversally relative to the fixed portion, allowing the template to adjust its width to accommodate different pocket shapes and openings while maintaining structural simplicity.
Solution Approach 2:
The template incorporates a mobile portion that can dynamically adjust its position transversally. This dynamic element allows the template to adapt to varying pocket widths and critical shapes without requiring a completely different template for each pocket type, thus improving versatility without excessive complexity.
2Ease of operation
If a one-piece template is used for pockets with narrow openings, then the template structure is simple, but the template cannot be inserted into or extracted from pockets with critical shapes
Solution Approach 1:
By segmenting the template into fixed and mobile portions, the mobile portion can be moved out of the way when inserting the template into pockets with narrow openings or critical shapes. This segmentation allows the template to be inserted and extracted without damaging the pocket or requiring the pocket to have a sufficiently wide opening.
Solution Approach 2:
The mobile portion's ability to move transversally provides operational flexibility. During insertion, the mobile portion can be retracted or positioned to minimize interference with narrow openings. During extraction, it can be adjusted to facilitate removal without damaging the pocket, thus improving ease of operation while maintaining compatibility with critical shapes.
3Adaptability or versatility
If the template size is changed to fit different pocket shapes, then versatility is improved, but the machine complexity increases
Solution Approach 1:
The template size adjustment is achieved through segmentation into fixed and mobile portions. The mobile portion can be moved independently to change the effective width of the template, providing size adjustment capability without requiring a complex mechanism. The segmentation allows for simple translational movement rather than complex expansion or contraction.
Solution Approach 2:
The template employs a dynamic mobile portion that can translate transversally to adjust the template's effective size. This dynamic adjustment is achieved through simple movement rather than complex mechanical transformation, maintaining relative simplicity while improving adaptability to different pocket shapes and dimensions.

AI summary
A machine (100) for attaching pockets (T) is disclosed, comprising a template (1) provided with two separate portions (15, 16a, 16b), wherein at least one portion (16a, 16b) of said at least two portions of the template is a mobile portion (16a, 16b) suitable for moving transversally with respect to a longitudinal direction (A), in such manner that the template can be in a maximum size configuration in transverse direction, which defines the pocket dimensions, and in a minimum size configuration in transverse direction, in order to insert and extract the template into and from the pocket.
