A manufacturing method for a flexible radiation detecting apparatus that involves forming a matrix array with a substrate, insulating layers, and pixels including a conversion element and a TFT, followed by fixing a flexible supporting member to cover the pixels and releasing the substrate, resulting in a lightweight, flexible, and reliable device with improved electromagnetic shielding and shock resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a glass substrate is used for the radiation detecting apparatus, then the structural strength and stability are improved, but the weight increases and flexibility decreases
Solution Approach 1:
The patent replaces the traditional rigid glass substrate with a flexible plastic substrate, allowing the radiation detecting apparatus to achieve both light weight and flexibility. The plastic substrate serves as the base layer upon which the pixel array and other components are formed, enabling the device to be bent and folded without breaking while maintaining structural integrity.
Solution Approach 2:
The patent employs a multi-layer composite structure consisting of plastic substrate, pixel array, scintillator layer, and electromagnetic shielding layer. This composite design combines the advantages of different materials: the plastic substrate provides flexibility and light weight, while the metal shielding layer provides electromagnetic interference protection, achieving a balance between various performance requirements.
2Stability of the object's composition
If a glass substrate is used for the radiation detecting apparatus, then the structural stability is improved, but the shock resistance decreases
Solution Approach 1:
The flexible plastic substrate can absorb and distribute mechanical shocks more effectively than rigid glass, preventing crack propagation and structural failure under impact conditions. This flexibility actually enhances the device's reliability in portable applications where drops and bumps are common.
Solution Approach 2:
The multi-layer composite structure with adhesive layers between components provides shock absorption and stress distribution, protecting the sensitive pixel array and conversion elements from damage during handling and transport.
3Adaptability or versatility
If a complex manufacturing process with multiple layers is used, then the device functionality is improved, but the device complexity increases
Solution Approach 1:
The patent divides the radiation detecting apparatus into distinct functional layers: pixel array layer, scintillator layer, and electromagnetic shielding layer. This segmentation allows each layer to be optimized independently for its specific function while simplifying the overall manufacturing process through modular assembly.
Solution Approach 2:
The plastic substrate serves multiple functions simultaneously: it acts as the structural base, provides flexibility, reduces weight, and serves as the mounting platform for all other components. This multi-functionality reduces the need for additional support structures, simplifying the overall device design.
