Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for determining the quality of liquid pharmaceutical products often require sample preparation, destruction of the sample, and specialized equipment and personnel, making them inefficient and unsuitable for sterile products.
Innovation Solution
A method and system that use a sealed container to form a sample layer of the liquid pharmaceutical product, allowing for non-destructive spectroscopic measurement (NIR or Raman) of the product's quality without opening the container, and comparing the measured spectrum to a reference spectrum to identify quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional quality determination methods are used, then quality assessment can be performed, but sample preparation is required and the sample is destroyed
Solution Approach 1:
The patent replaces traditional mechanical/sample-based quality determination methods with optical spectroscopy. A light source emits light through the sealed container wall and sample, and a detector captures the transmitted light to generate a spectrum. This optical method eliminates the need for physical sample preparation and destruction while maintaining quality assessment accuracy through spectral analysis comparison with reference spectra.
2Measurement precision
If traditional quality determination methods are used, then quality can be evaluated, but specialized equipment and trained personnel are required
Solution Approach 1:
The patent replaces complex traditional analytical equipment with a simplified optical system consisting of a light source, sealed container, and detector. The system automatically captures spectral data and compares it with reference spectra to determine quality, eliminating the need for specialized analytical laboratories and highly trained personnel while maintaining evaluation capability.
Solution Approach 2:
The system performs self-service quality determination by automatically comparing measured spectra with stored reference spectra. The comparison process identifies quality status without requiring expert intervention, making the system accessible to non-specialized personnel and reducing dependency on specialized knowledge.
3Measurement precision
If traditional quality determination methods are used, then quality assessment is possible, but the process is time-consuming and inefficient
Solution Approach 1:
The patent replaces time-consuming traditional quality determination procedures with rapid optical spectroscopy. The light source illuminates the sample through the sealed container, the detector immediately captures the transmitted light spectrum, and the system quickly compares it with reference spectra to determine quality. This process occurs in real-time without sample preparation or destruction, dramatically reducing measurement time while maintaining accuracy.
4Measurement precision
If traditional quality determination methods are used, then quality can be assessed, but sterility is compromised for sterile products
Solution Approach 1:
The patent replaces invasive quality assessment methods with non-invasive optical spectroscopy performed through the sealed container wall. The light source and detector measure the spectrum without breaching the seal, maintaining sterility while enabling quality determination. This is particularly valuable for sterile pharmaceutical products where maintaining the sterile barrier is critical.
