Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If glass substrates are used in digital radiographic detectors, then manufacturing precision and structural stability are improved, but weight increases and portability deteriorates
Solution Approach 1:
The patent changes the substrate material parameter from traditional glass to flexible materials such as polyimide or other flexible substrates. This material substitution maintains the structural integrity needed for manufacturing precision while dramatically reducing the weight of the detector, enabling portable bedside imaging applications.
Solution Approach 2:
The patent employs composite material structures where flexible substrate materials are combined with imaging sensor arrays and protective housings. This composite approach achieves both the structural stability required for precise manufacturing and the weight reduction necessary for portability, resolving the contradiction between these two parameters.
2Stability of the object's composition
If glass substrates are used in digital radiographic detectors, then structural stability is improved, but durability in portable applications deteriorates
Solution Approach 1:
The patent changes the substrate from rigid glass to flexible materials that can withstand portable handling conditions. This parameter change improves durability by eliminating the fragility inherent in glass while maintaining structural stability through the engineered flexible substrate design that supports the imaging components.
Solution Approach 2:
The patent implements flexible substrate films that provide both structural stability for component support and enhanced durability for portable use. These flexible films replace rigid glass while maintaining the necessary structural integrity, directly resolving the contradiction between structural stability and durability in portable applications.
3Strength
If traditional housing structures are used, then protection of internal components is improved, but weight and portability deteriorate
Solution Approach 1:
The patent changes the housing material parameters to lightweight materials that provide adequate protection without the weight of traditional heavy housings. This enables the detector to maintain component protection while achieving the weight reduction necessary for portable bedside imaging.
Solution Approach 2:
The patent uses composite housing structures that combine lightweight materials with protective features. This composite approach provides sufficient protection for internal components while minimizing weight, resolving the contradiction between protection strength and portability.

Function Achieved in This Case
The solution enhances the detector's portability and durability, allowing for efficient bedside imaging without the need for glass substrates, thus improving ease of use and reliability in critical care settings.
Implementation Method 1
A scintillator, or wavelength converter, may be disposed over the light sensitive sensing elements to convert incident x-ray radiographic energy to visible light energy.
Implementation Method 2
Each photosensitive cell 22 may independently store a charge proportional to an intensity, or energy level, of the attenuated radiographic radiation, or x-rays, received and absorbed in the cell.
