Method for realising articles having a predetermined area and aesthetic appearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for producing articles with predetermined areas and aesthetic appearances through punching, stitching, and cutting operations are costly and inefficient due to the need for multiple machines and manual alignment of materials, leading to increased operational complexity and time.
Innovation Solution
An apparatus with three stations that allows for sequential punching, stitching, and cutting operations using frames with sliding and coupling means, where the same references are maintained across all operations, reducing the need for manual alignment and enabling automation of the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If multiple separate machines are used for punching, stitching, and cutting operations, then each operation can be performed with dedicated equipment, but the operational complexity and costs increase due to manual alignment and transfer between machines
Solution Approach 1:
The patent combines punching, stitching, and cutting operations into a single integrated machine with multiple operating heads. The material portion remains blocked to the same frame throughout all operations, eliminating the need for manual transfer and alignment between separate machines. This merging reduces operational complexity and costs while maintaining dedicated functionality for each operation type.
2Productivity
If manual alignment and transfer of material between machines is required, then flexibility in operation sequencing is maintained, but productivity decreases due to dead times and operational delays
Solution Approach 1:
The integrated machine enables continuous processing where the material portion is punched, stitched, and cut without being removed from the frame or experiencing idle transfer time. Multiple operating heads can work in parallel or sequence on the same material portion simultaneously, eliminating dead times associated with manual transfer and alignment operations between separate machines.
3Manufacturing precision
If the same frame is used for all operations, then alignment precision is improved, but the device complexity increases due to integrated multiple operating heads
Solution Approach 1:
The single machine frame serves multiple functions by supporting different operating heads for punching, stitching, and cutting operations. The frame and blocking means provide a universal reference system that ensures precise alignment across all operation types without requiring separate alignment procedures for each machine, thereby improving manufacturing precision while consolidating device complexity into one multi-functional platform.

AI summary
A method for realizing articles having a predetermined area and aesthetic appearance uses frames to each of which a portion of material having a prevalent flat extension can be removably hooked. The method includes stitching or punching operations and cutting operations implemented on each portion of material in a first station, a second station and a third station sequentially. Cutting operations are executed on a first portion of material hooked to a first frame in a third station, while stitching or punching operations are carried out on a second portion of material hooked to a second frame and punching or stitching operations are performed on a third portion hooked to a third frame situated in the first station in phased relation.
