Fabric Attachment Device Using Die Transfer to Avoid Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In fabric attachment processes, holding members can interfere with fabric laminations, causing attachment objects to lose their correct posture and fail to attach properly, especially when placed adjacent to fabric steps or height differences.
Innovation Solution
An attaching apparatus with a first die and holding members that transfer the attachment object to a position away from the fabric before attaching, allowing the attachment object to maintain its posture and avoid interference, using a combination of mechanical movements and pivotable arm members to ensure correct positioning and attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the holding member (arm member) is used to hold the attachment object during attachment process, then the attachment object can be positioned on the fabric, but the holding member interferes with fabric laminations causing the attachment object to lose correct posture and fail to attach properly
Solution Approach 1:
The patent extracts the harmful function of the holding member by removing it from the attachment position. The holding member is taken out from the area where it would interfere with fabric laminations, allowing the attachment object to be positioned without interference while maintaining attachment reliability.
Solution Approach 2:
The patent introduces a die as an intermediary device to transfer the attachment object to the fabric. Instead of the holding member directly positioning the attachment object on the fabric (which causes interference), the die acts as a mediator that receives the attachment object from the holding member and places it on the fabric, eliminating the interference problem.
2Adaptability or versatility
If the attachment object is placed adjacent to fabric steps or height differences, then the attachment can be performed in complex fabric configurations, but the holding member cannot maintain the correct posture of the attachment object
Solution Approach 1:
The die serves as an intermediary that stabilizes the attachment object during transfer to complex fabric configurations. The die maintains the correct posture of the attachment object while moving it to positions adjacent to fabric steps or height differences, enabling versatile attachment locations without sacrificing posture stability.
Solution Approach 2:
The holding member preliminarily positions the attachment object in the correct posture before transfer, and the die maintains this posture during the transfer process to complex fabric configurations. This preliminary positioning combined with intermediary support ensures both adaptability to complex configurations and stability of posture.

AI summary
An attaching apparatus (100), which attaches an attachment object (20) to a fabric (30) using a fastening member (10), includes at least one pair of first holding members (40) configured to hold an attachment object (20); and a first die (110) configured to hold the attachment object (20) at a terminal (111) of a die main body (110k). The first die (110) moves such that the attachment object (20), held at the at least one pair of first holding members (40), is held at the terminal (111) of the die main body (110k) and then the attachment object (20) is placed onto the fabric (30). The attachment object (20) is transferred from the at least one pair of first holding members (40) to the first die (110) at a position distanced away from the fabric (30).
