Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible board TFT-based radiation detecting devices are vulnerable to vibration, leading to fluctuations in parasitic capacitance and noise superimposition, which degrade image quality and detection accuracy.
Innovation Solution
Incorporation of cushions at strategic locations within the radiation detecting device to suppress vibration, including between the supporter and radiation detector, and between the supporter and the rear part, while maintaining a lightweight configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If lightweight flexible board TFT configuration is used, then weight is reduced, but vibration resistance deteriorates
Solution Approach 1:
A vibration suppressor is introduced as an intermediary component between the flexible board TFT and the housing. This mediator absorbs and dampens vibrations transmitted to the flexible board, protecting it from harmful mechanical stress while maintaining the lightweight advantage of the flexible board configuration.
Solution Approach 2:
The vibration suppressor is pre-installed in the housing to provide cushioning protection before vibrations occur. This preventive measure ensures that when vibrations occur during transport or operation, the flexible board is already protected, preventing parasitic capacitance fluctuations and noise generation.
2Weight of moving object
If flexible board TFT is used, then weight is reduced, but image quality deteriorates due to vibration-induced noise
Solution Approach 1:
The vibration suppressor acts as a mediator that isolates the flexible board TFT from vibrations. By absorbing mechanical vibrations before they reach the TFT, the suppressor prevents fluctuations in parasitic capacitance and eliminates noise generation, thereby maintaining high image quality while preserving the lightweight advantage.
Solution Approach 2:
The vibration suppressor provides preliminary anti-action by counteracting vibrations before they can affect the flexible board TFT. This preemptive vibration damping prevents the chain reaction of parasitic capacitance changes and noise generation, protecting image quality in advance.
3Weight of moving object
If flexible board TFT is used, then weight is reduced, but detection accuracy deteriorates due to vibration
Solution Approach 1:
The vibration suppressor serves as a protective intermediary between the external vibration environment and the flexible board TFT. By dampening vibrations before they reach the detection elements, the suppressor maintains stable parasitic capacitance values and ensures accurate X-ray detection despite the lightweight flexible board construction.
