Laser Engraved Regulator Bonnet Marking Through Paint Layers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing marking systems for fluid control system components, such as regulator bonnets, face issues with visibility and durability, as traditional engraving methods like dot matrix engraving become illegible under paint and supporting documentation is often misplaced.
Innovation Solution
A system comprising processors, a laser engraver, and a printer that engraves fixed and variable information onto the bonnet through a paint and metallic coating layer into a base layer, while simultaneously printing matching labels, ensuring the markings are permanent and visible, and the labels are packaged with the component.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional dot matrix engraving is used to mark components, then the marking process is simple and quick, but the markings become illegible under paint and are not durable
Solution Approach 1:
The patent replaces traditional mechanical dot matrix engraving with laser engraving technology. The laser beam precisely removes material to create permanent markings that penetrate through paint layers, ensuring durability and legibility. This substitution of mechanical systems with optical/thermal energy-based systems resolves the contradiction by providing reliable, permanent markings without requiring complex mechanical engraving mechanisms.
Solution Approach 2:
The patent changes the fundamental parameter of marking depth and penetration. Instead of surface-level engraving that gets covered by paint, the laser engraving creates deep, permanent markings that extend through the paint layer into the base material. This parameter change ensures the markings remain legible and durable throughout the product lifecycle.
2Reliability
If markings are engraved into components, then the markings are permanent, but they become illegible when painted over
Solution Approach 1:
The patent performs the marking action before the painting process. By engraving the component markings first and then applying paint, the markings are created in a state where they can be properly formed. The laser engraving penetrates through the paint layer, ensuring the markings remain visible and legible despite the presence of paint coating.
Solution Approach 2:
The use of laser technology allows for precise, controlled engraving that creates markings capable of penetrating through paint layers. This replaces traditional mechanical engraving methods with optical/thermal energy, enabling markings to maintain visibility and legibility even when painted over, thus resolving the contradiction between marking permanence and visibility.
3Reliability
If supporting documentation is provided separately from the component, then the documentation can be produced efficiently, but it is often misplaced or lost
Solution Approach 1:
The patent merges the component marking process with the label printing process into a single integrated system. The laser engraves markings on the component while simultaneously printing corresponding labels with the same information. This integration ensures that documentation (labels) remains associated with the component, preventing misplacement or loss, while maintaining manufacturing efficiency through automated synchronized operation.
Solution Approach 2:
The integrated system uses feedback mechanisms to coordinate the marking and labeling processes. The system monitors the marking process and automatically triggers the label printing with matching information, ensuring that documentation is consistently paired with the correct component. This feedback loop prevents documentation loss by maintaining automatic association between components and their supporting information.
4Reliability
If laser engraving is used to create permanent markings, then the markings are highly visible and durable, but the equipment and process are more complex
Solution Approach 1:
The patent replaces complex mechanical engraving systems with laser-based marking technology. The laser system uses optical and thermal energy to precisely remove material and create permanent markings, eliminating the need for complex mechanical engraving mechanisms. This substitution maintains marking permanence and durability while simplifying the overall system architecture through non-contact, energy-based processing.

Function Achieved in This Case
The solution provides highly visible and permanent markings on the bonnets, preventing illegibility and ensuring that supporting documentation remains with the product, thus addressing the issues of illegible markings and misplaced documents.
Implementation Method 1

Data Source
AI summary
Systems and methods to facilitate permanently marking a housing component for a fluid control system product is disclosed. The system comprises a first processor, a second processor, and a printer. The first processor is configured to receive fixed information. The second processor is configured to receive the fixed information from the first processor, generate variable information, control a laser engraver to engrave the fixed and variable information into a workpiece, generate an information packet including the fixed information and the variable information, and transmit the information packet to the first processor.
