Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If destructive inspection methods (tablet slices) are used to test the structure and components of drug tablets, then measurement precision is improved, but the tablets are damaged and cannot be used for production line inspection
Solution Approach 1:
The patent replaces mechanical destructive inspection (tablet slicing) with terahertz electromagnetic wave inspection. The terahertz pulse generator emits pulses that penetrate the tablet, and the receiver detects the transmitted waves to obtain structural and compositional information without physical contact or damage to the tablet, enabling production line integration.
Solution Approach 2:
The patent introduces terahertz electromagnetic waves as an intermediary between the inspection system and the tablet. These waves serve as a mediator that carries information about the tablet's internal structure and composition through transmission, allowing non-destructive measurement of polymorphism, concentration, coating thickness, and porosity.
2Difficulty of detecting and measuring
If ultrasonic or X-ray inspection methods are used to examine drug tablets, then internal structure detection capability is improved, but the methods are not suitable for pharmaceutical production lines due to safety and complexity concerns
Solution Approach 1:
The patent changes the detection parameter from high-energy ultrasonic or X-ray waves to terahertz frequency electromagnetic waves. This parameter change reduces the energy level and potential harm to the pharmaceutical product while maintaining sufficient penetration and detection capability for internal structure analysis, making the method suitable for production line use.
Solution Approach 2:
The patent replaces complex ultrasonic or X-ray inspection systems with a terahertz pulse generation and detection system. This substitution simplifies the inspection apparatus while maintaining internal structure detection capability, improving productivity and production line compatibility.
3Ease of operation
If appearance inspection methods are used to examine drug tablets, then ease of operation is improved, but measurement precision for structure and components is insufficient
Solution Approach 1:
The patent transitions from surface-level appearance inspection to three-dimensional internal structure inspection using terahertz wave transmission. By measuring the transmission characteristics of terahertz pulses through the tablet, the system obtains information about internal structure, composition, and physical properties that cannot be obtained from external appearance alone, significantly improving measurement precision while maintaining operational simplicity.
