Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for evaluating the structural and functional properties of biological and non-biological materials, such as synthetic scaffolds and tissues, are inadequate as they rely on visual inspection and cannot accurately detect surface or subsurface defects, leading to potential failures in tissue engineering and implantation.
Innovation Solution
The use of infrared contrast analysis to detect and evaluate structural and functional characteristics by measuring changes in infrared emissivity, which are indicative of physical or functional properties, allowing for the identification of desired or deficient properties in materials and tissues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If visual inspection methods are used to evaluate material properties, then the evaluation process is simple and quick, but the detection precision of structural or functional deficiencies is insufficient
Solution Approach 1:
The patent replaces visual inspection (optical system) with infrared detection (thermal/thermal-infrared system). The infrared detector measures thermal radiation emitted by the material, converting thermal energy into electrical signals for analysis. This substitution enables detection of subsurface defects and functional properties that are invisible to the naked eye, significantly improving measurement precision while maintaining operational simplicity.
Solution Approach 2:
The patent changes the detection parameter from visible light reflection (visual inspection) to infrared thermal radiation emission. By measuring changes in infrared emissivity rather than visible appearance, the system can detect structural variations, surface defects, and functional characteristics that do not manifest visually. This parameter transformation enables precise detection of material properties without complicating the evaluation process.
2Measurement precision
If infrared detection is calibrated to temperature changes, then temperature measurement accuracy is improved, but sensitivity to physical or functional property changes is reduced
Solution Approach 1:
The patent fundamentally changes the calibration parameter from temperature to physical/functional properties. Instead of calibrating the infrared detector to detect only temperature changes, the system is calibrated to detect changes in infrared emissivity caused by physical properties (surface variations, cracks, folds) and functional characteristics. This parameter transformation enables the detector to reliably identify desired material properties while maintaining temperature measurement capability.
Solution Approach 2:
The patent introduces infrared emissivity as an intermediary parameter that mediates between temperature and material properties. By measuring infrared emission intensity and analyzing contrasts in emissivity patterns, the system can infer physical and functional characteristics without being confounded by temperature variations. This intermediary approach allows simultaneous detection of multiple properties, improving reliability for identifying desired characteristics.
3Loss of information
If visual evaluation is performed, then the inspection process is straightforward, but the ability to identify structural or functional deficiencies is limited
Solution Approach 1:
The patent substitutes visual inspection with infrared detection, replacing optical perception with thermal radiation measurement. The infrared detector captures thermal emission patterns that reveal structural deficiencies (cracks, folds, surface variations) and functional characteristics invisible to the naked eye. This substitution dramatically reduces information loss while maintaining operational ease, as the detection process remains automated and requires minimal operator intervention.
Solution Approach 2:
The patent adds a thermal dimension to the evaluation process by measuring infrared radiation rather than relying solely on visible light. This dimensional expansion enables detection of subsurface defects and functional properties that do not manifest in the visual spectrum. The infrared detection system captures thermal contrast information that complements visual inspection, providing comprehensive material characterization without complicating the evaluation procedure.
