Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for stripping aluminum foil from cables are inefficient and costly, as they require two expensive laser machines or involve flipping the cable to cut slits sequentially, reducing stripping efficiency.
Innovation Solution
An aluminum foil stripping device equipped with a single laser machine, a pair of cutters, and a grasping mechanism, which cuts a pre-cut in the aluminum foil to release tension, then simultaneously cuts the foil from both sides using the pair of cutters, and finally separates the foil from the cable using the grasping mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If two laser machines are used to cut slits on both radial sides of the aluminum foil layer simultaneously, then the stripping efficiency is improved, but the cost increases significantly
Solution Approach 1:
The patent combines the functions of two separate laser machines into a single laser machine that can cut slits on both radial sides of the aluminum foil layer simultaneously. This is achieved by equipping one laser machine with two cutting heads or by using a reflective mechanism, thereby maintaining high stripping efficiency while significantly reducing equipment cost and complexity
Solution Approach 2:
The single laser machine is designed to perform multiple functions: it can cut slits on both radial sides of the aluminum foil layer, and it can also potentially perform other cutting operations. This multi-functionality eliminates the need for multiple specialized laser machines, reducing both cost and device complexity while maintaining productivity
2Quantity of substance
If only one laser machine is used to cut slits on both radial sides of the aluminum foil layer, then the cost is reduced, but the stripping efficiency decreases due to sequential cutting requiring cable flipping
Solution Approach 1:
The patent introduces a new dimensional approach by enabling the single laser machine to cut on both radial sides simultaneously through dual cutting heads or reflective mechanisms. This transforms the sequential one-dimensional cutting process into a simultaneous two-sided process, eliminating the need for cable flipping and maintaining high stripping efficiency while using only one laser machine
Solution Approach 2:
The laser machine makes preliminary cuts (slits) on both radial sides of the aluminum foil layer before the actual stripping process. These pre-cuts are made simultaneously on both sides, releasing tension and preparing the foil for efficient removal, thereby maintaining high productivity without requiring two separate laser machines
3Device complexity
If a single laser machine is used with sequential cutting, then the device complexity is reduced, but the processing time increases due to cable flipping
Solution Approach 1:
The patent ensures continuous useful action by enabling the single laser machine to cut both radial sides of the aluminum foil layer simultaneously without interruption. The dual cutting heads or reflective mechanism allow both sides to be processed in one continuous operation, eliminating the time loss associated with stopping, flipping the cable, and resuming cutting
