Embroidery Machine Basting for Rigid Materials
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Embroidery sewing machines struggle to fix rigid or small materials like leather and plastic, as they cannot be securely held by traditional embroidery frames, and existing basting methods often result in pinholes or require manual operation, which impairs workability.
Innovation Solution
An embroidery sewing machine with a basting area accepting unit, basting data generating unit, and basting executing unit that allows users to specify and generate basting data according to the material's size, enabling precise basting without damaging the material and allowing for internal or covert fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an embroidery frame is used to hold the material, then the material can be fixed for embroidery, but rigid or small materials like leather and plastic cannot be securely held and may be damaged
Solution Approach 1:
An interliner is introduced as an intermediary between the embroidery frame and the material. The interliner is held by the embroidery frame, and the material is fixed over the interliner using basting stitches. This mediator allows rigid or small materials to be secured without direct contact with the frame, preventing damage while ensuring reliable fixation.
2Reliability
If basting is performed at the center of the material, then the material can be fixed securely, but pinholes are created that spoil the embroidery work
Solution Approach 1:
The basting stitches are extracted from the visible embroidery area and relocated to covert portions around the material or to areas that will be stitched inside or cut. This removes the harmful pinholes from the visible work area while maintaining secure fixation in the non-visible areas.
3Reliability
If manual feeding is used for basting, then the material can be fixed, but workability is considerably impaired
Solution Approach 1:
The embroidery sewing machine automatically generates basting data based on the embroidery pattern and material size, and performs basting stitching without requiring manual feeding operations. The system serves itself by computing the necessary basting parameters and executing the fixation process automatically, greatly improving workability while maintaining reliable fixation.

AI summary
An embroidery sewing machine having a function of fixing an interliner and a material by basting, and capable of performing embroidery sewing based on embroidery sewing data includes: a basting area accepting unit configured to perform an assisting operation for a user so as to allow the user to specify an area for basting according to a size of a material, and to accept the specification of the area for basting; a basting data generating unit configured to generate basting data according to the area accepted by the basting area accepting unit; and a basting executing unit configured to perform basting based on the basting data generated by the basting data generating unit.
