Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ionizing radiation detectors with continuous detection surfaces face limitations in size due to electrical conductor constraints, leading to serial connection issues, voltage fluctuations, and reduced data collection rates, as well as temperature instability and sensitivity distortions.
Innovation Solution
The module design features detection segments arranged side by side on a row carrier with a clearance of up to 30 µm, using a printed circuit board for parallel or serial connection and integrating power supply stabilization close to the segments, with thermal bridges to stabilize temperature and ensure a stable power supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If detection segments are arranged tightly side by side on a row carrier with limited space for electrical conductors, then the continuous detection surface is achieved, but the number of segments that can be connected in a single row is limited and serial connection leads to longer response time
Solution Approach 1:
The patent transitions from one-dimensional serial connection along the row carrier to two-dimensional parallel connection by routing electrical conductors through the vertical dimension (below the row carrier) and using multiple connection points. This allows multiple detection segments to be connected simultaneously in parallel, dramatically increasing data acquisition speed while maintaining the continuous detection surface.
Solution Approach 2:
The patent introduces an intermediary structure (the row carrier with integrated conductor routing channels and connection interfaces) that mediates between the detection segments and the readout electronics. This intermediary enables efficient parallel signal transmission by providing dedicated conductor paths for multiple segments without requiring direct adjacent connections.
2Ease of manufacture
If electrical conductors are led along the row carrier in limited space, then connection to detection segments is achieved, but power supply stabilization is too remote from detection segments causing voltage fluctuations
Solution Approach 1:
The patent applies local quality by positioning power supply stabilization components in close proximity to each detection segment rather than using a single remote power supply. Each detection segment or small group of segments has its own dedicated power supply connection points located immediately adjacent to them on the row carrier, ensuring stable voltage supply without long conductor runs.
3Measurement precision
If detection segments are arranged in a continuous surface without edges, then clear resulting image is achieved, but sufficient space must be provided for connecting electrical conductors disrupting the continuous detection surface
Solution Approach 1:
The patent resolves the conflict between image continuity and conductor space by moving conductor routing to the vertical dimension (below the row carrier level) and utilizing the overlap regions between adjacent detection segments. This allows electrical conductors to pass through non-detection areas without creating visible disruptions or dead spots in the continuous detection surface.
Solution Approach 2:
The patent employs nesting by placing electrical conductors and connection structures within the overlap regions of adjacent detection segments. The conductors are nested in the non-sensitive peripheral areas of the segments, allowing them to share the same physical space without interfering with the active detection surfaces, thus maintaining continuous image coverage.
