Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rigid digital image sensors cause discomfort and pain during X-ray imaging of internal mouth structures due to their inability to withstand the physical forces applied during the imaging process, and there is a lack of specific technology for a bendable image sensor to address this issue.
Innovation Solution
A bendable X-ray image sensor with a thin sensor panel, a flexible printed circuit board, and an elasticity adjustment member made of elastic material, where the elasticity of the sensor panel and printed circuit board is equal to or higher than the elasticity adjustment member, allowing the sensor to be bent within a predetermined elastic limit, reducing tension stress and maintaining reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a rigid digital image sensor is used for X-ray imaging of internal mouth structures, then the sensor can maintain structural stability and reliability, but it causes discomfort and pain to the patient due to its inability to withstand physical forces during imaging
Solution Approach 1:
The patent applies this principle by using a thin sensor panel (30-70 μm thickness) that can bend and adapt to the contours of internal mouth structures. The sensor panel is designed with flexible materials and a thin profile that allows it to withstand physical forces during imaging without causing patient discomfort, while still maintaining sufficient structural stability for reliable X-ray detection
Solution Approach 2:
The patent employs composite materials in the sensor panel construction, combining flexible substrate materials with scintillator layers and photodetector elements. This composite structure enables the sensor to achieve both flexibility for patient comfort and sufficient mechanical strength for reliable operation during X-ray imaging of internal mouth structures
2Adaptability or versatility
If the sensor panel is made thin to enable bending, then the sensor can adapt to internal mouth structures, but the structural stability and reliability may be compromised
Solution Approach 1:
The patent uses composite materials consisting of a thin flexible substrate (30-70 μm) combined with scintillator layers and photodetector elements. This composite construction provides both the necessary flexibility for bending and adapting to internal mouth structures and sufficient structural stability for reliable X-ray detection, resolving the contradiction between thinness for adaptability and strength for reliability
Solution Approach 2:
The sensor panel employs local quality by varying the thickness and material properties in different regions. The thin flexible regions enable bending and adaptation, while strategically positioned stronger elements maintain structural stability and reliability for X-ray detection, allowing the sensor to achieve both adaptability and reliability simultaneously
