Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The quality of species used in analytical and diagnostic procedures, such as PET and targeted radiotherapy, is often compromised during transit from manufacturer to end user due to the fragile nature of these molecules and their short half-lives, making existing quality control methods inadequate.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If quality control is performed at the manufacturer site, then manufacturing precision is improved, but reliability deteriorates due to transit degradation of fragile species
Solution Approach 1:
The patent implements quality control measurements at the end user site immediately before the species is used in diagnostic or therapeutic procedures. This preliminary action ensures that any degradation occurring during transit is detected, and the species is verified to still meet quality criteria before administration to the patient, thereby resolving the contradiction between manufacturing precision and reliability.
2Loss of time
If rapid quality control is implemented at end user site, then time loss is reduced, but measurement precision may deteriorate due to simplified testing
Solution Approach 1:
The patent extracts the essential quality control measurements from complex manufacturer-site testing and implements them at the end user site. By focusing on critical parameters such as species concentration, purity, and functional activity using streamlined but rigorous assays, the system achieves rapid verification without sacrificing measurement precision, thus resolving the time-loss versus precision contradiction.
Solution Approach 2:
The patent adapts quality control parameters to be suitable for rapid end user site testing while maintaining precision. This includes using stable reference standards, optimizing assay conditions for speed without compromising accuracy, and establishing acceptance criteria that ensure species quality despite the reduced time frame, thereby resolving the contradiction between rapid testing and measurement precision.
3Measurement precision
If complex interaction detection is used, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent employs intermediary elements such as capture antibodies, reference standards, and control reagents that facilitate precise interaction detection without requiring complex equipment. These intermediaries enable accurate measurement of species quality parameters through well-established biochemical interactions, resolving the contradiction between measurement precision and device complexity by achieving high accuracy through biochemical mediators rather than technological complexity.

AI summary
A method for quality control of species used in analytical or diagnostic or therapeutic procedures includes immobilization of a model of the malignancy to a solid support (121), contacting the solid support with species dissolved in liquid (122), measuring both the rate of formation of complex and absolute magnitude of number of complexes of model and species (123) and determining the quality of species by comparing the measured values with predetermined values.
