Topographic Identification on Curved Sealing Components
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in applying multiply redundant information on small components with curved surfaces, such as toroidal surfaces, for secure and readable identification using traditional areal surface readers.
Innovation Solution
A two-dimensional coded identification is developed that follows the curved surface with minimal distortion, allowing for segmentation and arrangement of symbols and segments to ensure readability, even on complex shapes like O-rings, using laser marking to create a topographic identification that can be read without distorting the information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiply redundant information is applied on small curved surfaces, then security against falsification is improved, but readability with traditional areal surface readers deteriorates
Solution Approach 1:
The identification is divided into multiple segments distributed around the curved surface. Each segment contains partial identification information, and traditional readers can read at least one complete segment to identify the component. This segmentation allows redundant information storage while maintaining compatibility with traditional areal surface readers.
Solution Approach 2:
The identification is arranged to follow the curved surface geometry, transitioning from a flat areal surface concept to a three-dimensional curved surface adaptation. The identification segments are positioned and oriented to conform to the surface curvature, enabling readable identification on toroidal and other curved geometries while maintaining two-dimensional readability for traditional readers.
2Adaptability or versatility
If identification follows the curved surface, then adaptability to component shapes is improved, but distortion of the identification increases
Solution Approach 1:
Different segments of the identification are positioned in regions with varying distortion characteristics of the curved surface. Critical identification elements are placed in low-distortion areas, while other segments tolerate higher distortion. This local optimization ensures overall readability while maintaining adaptability to the component's curved geometry.
