Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surface quality inspection methods for cartomizers and other inhaler components are inefficient, causing damage and high costs due to complex handling processes, long assembly times, and inability to inspect multiple components simultaneously without surface imperfections.
Innovation Solution
A method and apparatus that rotate the component around its longitudinal axis to position it in distinct optical inspection zones, acquiring images from multiple angles to inspect the entire external surface without damaging it, using internal surface handling to frame and move the component, allowing for simultaneous inspection of multiple components in a short time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If numerous manipulations are performed to inspect the external surface, then inspection completeness is improved, but surface damage increases and inspection time increases
Solution Approach 1:
The patent uses optical imaging to create a visual copy of the external surface for inspection, eliminating the need for physical manipulations. Multiple images are captured from different angles and combined to form a complete visual record, allowing thorough inspection without touching the surface
Solution Approach 2:
The patent replaces mechanical manipulation methods with an optical inspection system. Instead of physically handling and repositioning the cartomizer multiple times, the system uses cameras and image processing to inspect the surface from multiple angles, substituting mechanical action with optical detection
2Measurement precision
If numerous manipulations are performed to inspect the external surface, then inspection completeness is improved, but production time increases
Solution Approach 1:
The patent implements a periodic inspection process where the cartomizer is inspected at multiple discrete angular positions (e.g., 0°, 45°, 90°, 135°) during its passage through the inspection zone. This periodic sampling at key positions ensures complete coverage while maintaining efficient production flow
Solution Approach 2:
The inspection process operates continuously as cartomizers move through the inspection zone on the production line. Multiple cameras capture images simultaneously or in rapid sequence, and image processing occurs in real-time, eliminating idle time between inspection steps and maintaining continuous production flow
3Adaptability or versatility
If the component is handled to inspect the external surface, then inspection capability is improved, but surface aesthetic quality deteriorates
Solution Approach 1:
The system creates optical copies (images) of the external surface from multiple angles and combines them into a comprehensive inspection dataset. This allows versatile inspection capabilities including detection of scratches, dents, and aesthetic defects without any physical contact that could compromise surface quality
4Device complexity
If traditional inspection methods are used, then equipment complexity is reduced, but inspection precision and speed decrease
Solution Approach 1:
The inspection system is designed to be universally applicable to different cartomizer models and inspection requirements. The same optical platform can capture images for multiple purposes including surface defect detection, dimensional verification, and aesthetic quality assessment, providing multi-functional inspection capabilities
Solution Approach 2:
The patent introduces an image processing unit as an intermediary between the optical cameras and the final inspection decision. This intermediary layer analyzes the captured images using algorithms to detect surface imperfections, enhancing inspection precision while keeping the physical hardware relatively simple
