Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current quality management systems lack effective indicators that can provide machine-readable signals for exceedance of thresholds related to product quality parameters, leading to inaccuracies and inefficiencies in tracking and reporting.
Innovation Solution
A barcoded indicator system that includes multiple barcodes with colorable areas, where the visibility and readability of these areas change based on threshold exceedance, allowing for a machine-readable indication of quality parameter exceedance, such as temperature and time thresholds, through a coloring agent that diffuses and changes the barcode's readability state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple barcodes are used to indicate different quality parameter thresholds, then the system can track multiple parameters simultaneously, but the complexity of the indicator increases and may lead to reading errors
Solution Approach 1:
The quality indicator is segmented into multiple distinct barcode regions, each representing a different quality parameter threshold. This allows the system to track multiple parameters (temperature, time, humidity) simultaneously while maintaining clear separation between each parameter's indication mechanism, thereby managing complexity through structured division.
Solution Approach 2:
The patent transitions from traditional single-dimension quality indicators to a multi-dimensional barcode system where different spatial arrangements and configurations of barcode bars encode multiple quality parameters. By utilizing dimensional variations in barcode structure rather than adding separate physical indicators, the system achieves multi-parameter tracking without proportionally increasing overall device complexity.
2Measurement precision
If colorable areas are added to barcodes to indicate threshold exceedance, then machine-readable indication of quality exceedance is achieved, but the manufacturing complexity increases
Solution Approach 1:
The patent incorporates colorable areas within barcode structures that change color or become visible when quality thresholds are exceeded. This provides clear machine-readable indication of threshold violations through optical changes in the barcode itself, enhancing measurement precision by making exceedance events visually and optically detectable without requiring separate sensing systems.
Solution Approach 2:
The manufacturing process utilizes parameter changes in the colorable materials, where physical or chemical properties of the coloring agents respond to quality parameter changes (temperature, time, humidity). This allows the indicator to automatically reflect quality status through material property changes, achieving accurate threshold detection while using commercially available smart materials that simplify rather than complicate manufacturing.
3Measurement precision
If the barcode readability changes based on threshold exceedance, then accurate quality status indication is provided, but reliability of barcode reading may be compromised
Solution Approach 1:
The barcode system transitions from static to dynamic readability, where the optical properties of barcode bars change in response to quality parameter thresholds. Colorable areas dynamically alter their optical characteristics based on environmental conditions, providing accurate real-time quality status indication while maintaining barcode structure integrity for reliable reading.
Solution Approach 2:
The system incorporates feedback mechanisms where the barcode's optical state provides continuous information about quality parameter status. The colorable areas respond to threshold conditions and provide visual and machine-readable feedback about exceedance events, allowing the system to accurately communicate quality status while maintaining readable barcode structures through controlled optical changes rather than complete obfuscation.
