Measurement Tip Printing Layer for Spatial Clearance Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing component measurement systems for liquids, such as blood glucose meters, are affected by manufacturing errors in the spatial clearance of measurement tips, leading to inaccurate results and increased costs in mass production.
Innovation Solution
The use of a printing layer on the measurement tip to provide information about the spatial clearance, which can be easily read by the measurement device, allowing for accurate component measurement by accounting for variations in tip geometry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the spatial clearance of the measurement tip is changed due to manufacturing error, then the measurement accuracy deteriorates, but mass production requirements demand acceptance of such variations
Solution Approach 1:
The invention applies preliminary action by pre-printing the spatial clearance information on the measurement tip during manufacturing. This allows the measurement device to acquire and use the actual clearance value before performing the measurement, enabling correction of manufacturing variations without requiring tighter manufacturing tolerances.
Solution Approach 2:
The invention implements feedback by using the printed spatial clearance information to adjust and correct the measurement results. The measurement device reads the actual clearance from the tip and uses this feedback to compensate for deviations from the nominal clearance value, thereby maintaining measurement accuracy despite manufacturing variations.
2Measurement precision
If a cutout portion is added to the measurement tip to store clearance information, then measurement accuracy improves, but device complexity and manufacturing cost increase
Solution Approach 1:
The invention extracts only the essential information (spatial clearance value) and stores it in a simple printed form on the measurement tip, rather than adding complex mechanical structures like cutout portions. This minimal extraction of information achieves the goal without significantly increasing device complexity.
Solution Approach 2:
The invention uses a simple printed layer on the disposable measurement tip to store clearance information. This approach is cost-effective for mass production of disposable tips, as printing is much cheaper than adding mechanical features, and the information can be easily applied during the manufacturing process.
3Loss of information
If a cutout portion is retrofitted in manufacturing the measurement tip, then clearance information can be provided, but additional manufacturing errors may occur and production costs increase
Solution Approach 1:
The invention replaces the mechanical approach of adding cutout portions with a printing-based information storage method. This substitution eliminates the need for additional mechanical manufacturing steps, reducing both complexity and the risk of introducing new manufacturing errors while maintaining ease of mass production.
