Pharmaceutical Syringe Label End Recognition for Reliable Reading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional information recording media fail to ensure proper reading of information symbols when affixed to the outer peripheral face of a columnar body, as symbols may be incomplete or obscured due to overlapping ends of the sheet-form member.
Innovation Solution
Incorporating an end recognition component at one or both ends of the sheet-form member, allowing the information reading device to recognize the end and ensuring that only uncovered information symbols are read, even when the sheet-form member is wound around a columnar body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the information recording medium is affixed to the outer peripheral face of a columnar body, then the information can be stored on the syringe, but the information symbol may be incomplete or obscured due to overlapping ends, making it unreadable
Solution Approach 1:
The information recording medium is divided into multiple separate labels rather than using a single continuous sheet. Each label contains complete information symbols and is positioned independently on the syringe body, eliminating the problem of overlapping ends obscuring data.
Solution Approach 2:
Instead of wrapping a continuous sheet around the syringe in one dimension, the invention uses multiple discrete labels distributed around the circumference. This dimensional reorganization ensures that at least one label remains fully visible and readable regardless of the syringe's orientation.
2Adaptability or versatility
If the sheet-form member is wound around the columnar body so that information symbols are present all the way around, then reading coverage is improved, but the overlapping ends cover part of the information symbol, preventing proper reading
Solution Approach 1:
The continuous information recording medium is segmented into multiple discrete labels. Each label is independently affixed to the syringe body at different angular positions, ensuring that the information symbols on each label remain complete and uncovered by overlapping edges.
Solution Approach 2:
Different regions of the syringe are assigned different labels with specific information symbols. The labeling strategy ensures that at least one label is positioned in a region accessible to the light receiving element, optimizing reading reliability for each local area.
3Reliability
If multiple identical information symbols are provided on the information recording medium, then reading reliability is enhanced, but the complexity of the information recording medium increases
Solution Approach 1:
Instead of duplicating multiple identical symbols on a single continuous sheet, the invention distributes multiple labels with identical information symbols across different positions on the syringe. This segmentation approach maintains reliability while simplifying the structure of each individual label.

AI summary
It is an object to provide an information recording medium with which information symbols can be suitably read. This information recording medium comprises a sheet-form member (33), a plurality of information symbols (18) that are displayed on the surface of the sheet-form member (33) and each have the same information, and an edge line (34) that is provided at one end and/or the other end of the sheet-form member (33) and allows an information reading device which reads the information symbols (18) to recognize the end of the sheet-form member (33).
