Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional pixel-type radiation detectors are used, then radiation detection capability is achieved, but position detection accuracy deteriorates due to inability to distinguish simultaneous signals
Solution Approach 1:
The invention divides the detection system into multiple independently connected external terminals, each capable of receiving and processing signals separately. This segmentation allows simultaneous signals from different pixel electrodes to be distinguished and processed independently, resolving the contradiction between measurement precision and reliability.
2Measurement precision
If multiple external terminals are connected to wiring substrate individually, then signal separation and position detection accuracy improve, but assembly time increases
Solution Approach 1:
The invention merges multiple external terminal connections into a collective connection structure where all external terminals are simultaneously connected to the wiring substrate through a unified interface. This combining approach maintains signal separation capability while dramatically reducing assembly time, resolving the contradiction between measurement precision and time loss.
3Productivity
If external terminals are collectively connected to wiring substrate, then assembly time reduces and productivity increases, but signal processing capability must be maintained
Solution Approach 1:
The collective connection structure is designed with segmented signal paths that maintain electrical independence for each external terminal while physically grouping them together. This segmentation within unity allows fast assembly without compromising signal processing capability, resolving the contradiction between productivity and device complexity.
