Sewing System Single Holding Frame Temporal Overlap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sewing systems require multiple material holders and manual intervention, leading to inefficiencies and increased setup costs, as they lack a seamless integration of sewing and transport processes.
Innovation Solution
A sewing system utilizing a single holding frame with a gripping robot that enables temporal overlap between sewing transport and supply transport, allowing for continuous operation without the need for multiple holders and manual loading, and combining supply and removal functions for enhanced efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple material holders are used, then continuous sewing operation is possible, but device complexity and setup costs increase
Solution Approach 1:
The patent combines the functions of multiple material holders into a single holding frame that can accommodate multiple sewing material parts simultaneously. The holding frame is designed with a contour adapted to the seam to be formed, allowing multiple material parts to be held and processed in one unified structure rather than requiring separate holders for each piece.
Solution Approach 2:
The single holding frame serves multiple functions: it holds multiple sewing material parts, guides them through the sewing process, and enables continuous operation by allowing the operator to load new material parts while previous ones are being sewn. This multi-functional design eliminates the need for multiple specialized holders.
2Ease of manufacture
If manual loading of material holders is required, then setup costs are reduced, but temporal efficiency decreases
Solution Approach 1:
The holding frame is designed to enable continuous operation where the operator can load new sewing material parts onto the frame while previous parts are being processed through the sewing machine. This continuous loading process eliminates idle time and ensures the sewing operation can proceed without interruption, maintaining constant productive action.
3Device complexity
If a single holding frame is used, then setup costs are reduced, but the ability to maintain continuous operation may be compromised
Solution Approach 1:
The holding frame is segmented into multiple positions or slots that can accommodate individual sewing material parts. Each segment can be independently loaded and positioned, allowing the operator to prepare new parts while others are being processed. This segmentation within a unified frame maintains simplicity while enabling continuous operation.
