Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional intra oral sensor devices for X-ray scans are either prone to image distortion due to rigidity or cause patient discomfort due to inflexibility, and there is a need for a device that is bendable to alleviate these issues.
Innovation Solution
A bendable intra oral sensor device with a window cover and elasticity adjustment member, featuring grooves in the side walls and a soft mold housing, allowing limited flexibility to minimize image distortion and patient discomfort during scans.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a rigid intra oral sensor device is used, then image distortion is reduced, but patient comfort deteriorates due to strong foreign sensation and pain
Solution Approach 1:
The sensor device is divided into multiple structural segments including a sensor assembly, window cover with side walls, grooves in side walls, and a mold housing. This segmentation allows different parts to have different functions - the rigid sensor assembly maintains image quality while the flexible mold housing and grooved side walls provide adaptability and comfort.
Solution Approach 2:
The patent changes the physical parameters of the device by introducing flexibility through the mold housing and grooves in the side walls. This allows the device to bend within a certain range, transforming it from a completely rigid structure to one with controlled flexibility, thereby reducing patient discomfort while maintaining image quality.
2Object-affected harmful factors
If a bendable intra oral sensor device is used, then patient comfort improves, but image distortion increases due to excessive twist
Solution Approach 1:
Different parts of the device have different mechanical properties - the sensor assembly and window cover base part maintain rigidity for image quality, while the side walls with grooves and the mold housing provide flexibility for patient comfort. This local differentiation of quality allows the device to simultaneously achieve both goals.
Solution Approach 2:
The device combines materials and structures with different mechanical properties - rigid components (sensor assembly, window cover base) and flexible components (mold housing, grooved side walls). This composite structure allows the rigid parts to maintain image quality while flexible parts provide comfort and limited bendability.
3Object-affected harmful factors
If the sensor device is made flexible, then foreign sensation is reduced, but structural stability deteriorates
Solution Approach 1:
The device transitions from a static rigid structure to a dynamic structure that can adapt its shape. The mold housing and grooves allow controlled bending and deformation, enabling the device to dynamically adjust to the patient's oral cavity while maintaining structural integrity through its composite design.
