Radiation Imaging Sensor Panel Noise Shielding via Vertical Circuit Stacking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Radiant noise from circuit boards significantly influences sensor signals in radiation imaging apparatuses, particularly from the power supply circuit board, leading to signal degradation, and existing noise isolation methods increase the apparatus' size.
Innovation Solution
The radiation imaging apparatus arranges a digital circuit board with a smaller radiant noise generation between the sensor panel and the power supply circuit board, acting as a noise shield, and optionally uses a shield member or convex housing design to further reduce noise impact, while maintaining a compact size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a metal partition is used to isolate the sensor panel and power supply circuit board horizontally, then the influence of radiant noise is reduced, but the size of the housing increases
Solution Approach 1:
The patent transitions from horizontal isolation (2D plane separation) to vertical stacking (3D spatial arrangement). By arranging the analog circuit board, digital circuit board, and power supply circuit board in a vertical stack above the sensor panel, the design achieves noise isolation without increasing the horizontal footprint of the housing, thus resolving the contradiction between noise reduction and compact size.
Solution Approach 2:
The patent implements a nested arrangement where multiple circuit boards (analog, digital, power supply) are stacked vertically one above another, forming a compact tower structure above the sensor panel. This nesting approach maximizes spatial utilization and achieves effective noise isolation through layered positioning without expanding the overall housing dimensions.
2Volume of stationary object
If circuit boards are arranged close to the sensor panel to reduce housing size, then the apparatus becomes more compact, but the influence of radiant noise on sensor signals increases
Solution Approach 1:
The patent applies local quality by assigning specific functional roles to different vertical layers: the analog circuit board processes sensor signals immediately above the sensor panel, the digital circuit board handles digital processing above that, and the power supply circuit board provides power at the top. This functional stratification allows close proximity for signal integrity while maintaining noise isolation through the layered architecture.
Solution Approach 2:
By moving from horizontal to vertical arrangement, the patent achieves compact volume while maintaining adequate separation distances in the vertical dimension. The stacked configuration allows circuit boards to be physically close to the sensor panel for signal integrity while the vertical stacking itself provides natural noise isolation through spatial separation in the third dimension.
