Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing drip irrigation pipes require additional time and equipment for labeling, as they involve separate processes for creating outlet openings and applying labels, which is inefficient and costly.
Innovation Solution
The method involves using a laser drilling device with adjustable radiation intensity to create both outlet openings and alphanumeric labels on the surface of the pipes during the same production process, leveraging the existing equipment to simplify and streamline the manufacturing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a separate labeling process is used after pipe production, then labels can be applied to the pipes, but additional time and equipment are required
Solution Approach 1:
The patent combines the labeling function with the existing laser drilling device used for creating outlet openings. The laser device performs dual functions: drilling outlet holes at high power and burning labels at reduced power, eliminating the need for separate labeling equipment and processes.
Solution Approach 2:
The laser drilling device is made multi-functional by enabling it to perform both outlet opening creation and label application. The same laser beam, optics, and positioning system are used for both operations, with only the power intensity needing adjustment.
2Manufacturing precision
If additional marking equipment is introduced for labeling, then labeling can be performed, but device complexity and costs increase
Solution Approach 1:
The laser drilling device is made multi-functional by enabling it to perform both outlet opening creation and label application. The same laser beam, optics, and positioning system are used for both operations, with only the power intensity needing adjustment.
Solution Approach 2:
The laser power intensity is varied to perform different functions: high intensity for drilling outlet openings and reduced intensity for burning labels. This parameter change allows one device to perform multiple operations that would traditionally require different equipment.
3Manufacturing precision
If high radiation intensity is used for drilling outlet openings, then precise holes are created, but the dosing element may be damaged causing leaks
Solution Approach 1:
The laser operation is divided into distinct phases with different power intensities. First, high-power drilling creates the outlet opening, then the power is reduced for label burning. This periodic variation in intensity prevents damage to the dosing element while achieving both objectives.
Solution Approach 2:
The laser power intensity is dynamically adjusted during the process: high intensity during drilling to create precise outlet openings, then reduced to lower intensity for label application. This parameter change ensures both precision and component protection.
