Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional imaging systems use rigid substrates, then manufacturing precision and structural stability are improved, but portability and adaptability to restricted spaces deteriorate
Solution Approach 1:
The patent applies flexible substrates (thin films) to replace conventional rigid substrates in imaging systems. The flexible substrate allows the imaging system to be bent, folded, or conformally mounted on curved surfaces, enabling portability and adaptability to restricted spaces while maintaining the functional integrity of the imaging components integrated on the substrate.
Solution Approach 2:
The patent changes the physical parameter of the substrate from rigid to flexible, fundamentally altering the mechanical properties of the imaging system. This parameter change enables the system to transition from a fixed, stationary configuration to a portable, adaptable configuration that can be deployed in diverse environments including remote locations and confined spaces.
2Reliability
If conventional imaging systems are designed for stability, then reliability is improved, but weight and volume increase reducing portability
Solution Approach 1:
The flexible substrate enables a thin-film construction that significantly reduces the weight and volume of the imaging system compared to conventional rigid substrates. The thin-film nature of the flexible substrate allows the system to achieve portability while maintaining structural integrity and operational reliability through proper material selection and device design.
3Ease of manufacture
If scintillator layers are separately manufactured and assembled, then manufacturing flexibility is improved, but device complexity and manufacturing precision deteriorate
Solution Approach 1:
The patent merges the scintillator layer manufacturing with the substrate fabrication process by directly forming the scintillator layer on the flexible substrate in an integrated manner. This consolidation eliminates separate assembly steps, reduces device complexity, and maintains manufacturing flexibility through a unified fabrication process that can be performed using standard thin-film deposition techniques.
Solution Approach 2:
The flexible substrate serves multiple functions simultaneously: it acts as the mechanical support structure, the flexible foundation for integration, and the platform for scintillator layer formation. This multi-functionality reduces the number of separate components and assembly operations required, simplifying the overall device structure while maintaining ease of manufacture.
