Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging machines require significant effort and costly, specialized cutting tools for format changes, leading to inefficiencies and high operational costs due to the need for custom-made complete cutting tools for each packaging shape.
Innovation Solution
A format-variable laser cutting unit with a control unit and data memory for storing cutting data and program packages for different pack formats, allowing for easy format changes and eliminating the need for complex, custom-made tools, using a freely positionable and programmable laser cutting tool that can produce various pack shapes with adjustable cutting paths and contours.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If custom-made complete cutting tools are used for each pack shape, then cutting precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent applies a single laser cutting tool that can process multiple pack formats by adjusting programming parameters rather than requiring separate custom cutting tools for each format. The control unit stores multiple data sets corresponding to different pack formats, allowing the same physical tool to perform multiple cutting functions through software configuration.
Solution Approach 2:
The patent replaces traditional mechanical cutting tools with a laser cutting tool. The laser beam can be precisely positioned and controlled to cut various pack shapes without physical contact, eliminating the need for mechanical punches and dies that require custom fabrication for each format.
2Manufacturing precision
If custom-made complete cutting tools are procured for each pack shape, then cutting precision is improved, but conversion time and operational cost increase
Solution Approach 1:
The control unit is designed to store multiple data sets for different pack formats, allowing operators to switch between formats by selecting different stored programs rather than physically changing tools. This universal control system eliminates the time required for tool procurement and installation when changing formats.
Solution Approach 2:
Multiple data sets for different pack formats are pre-stored in the control unit's memory. When a format change is needed, the system simply retrieves the pre-prepared data set and activates the corresponding cutting path, eliminating the need for real-time tool setup or recalculation.
3Adaptability or versatility
If format-variable laser cutting unit is used, then adaptability is improved, but manufacturing precision may worsen
Solution Approach 1:
The laser cutting tool with programmable control provides both high adaptability and precision. The laser beam can be precisely positioned and controlled to cut various pack shapes without physical contact, eliminating the need for mechanical punches and dies that require custom fabrication for each format.
