Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the effective area of radiation detector is increased to improve detection accuracy, then radiation detection accuracy is improved, but device structure becomes more complex
Solution Approach 1:
The patent transitions from a planar arrangement where detectors lie flat on the substrate to a three-dimensional vertical arrangement where detectors stand perpendicular to the substrate. This dimensional change allows the detection surface to extend vertically, dramatically increasing the effective detection area without proportionally increasing the substrate footprint or overall device complexity.
Solution Approach 2:
The patent divides the detection system into multiple independent detector elements that can be individually positioned at vertical angles. Each detector segment can be optimized for specific detection tasks, and the modular segmentation allows for scalable configuration to achieve desired detection area without requiring a monolithic complex structure.
2Area of stationary object
If multiple detectors are arranged to increase effective detection area, then detection coverage is improved, but wiring and electrical connection complexity increases
Solution Approach 1:
The patent employs a universal substrate structure that serves multiple functions: it provides mechanical support for vertical detector mounting, establishes electrical connections through conductive patterns, and enables signal routing. This multi-functional substrate design consolidates what would otherwise require separate components, thereby increasing detection area while managing wiring complexity through integration.
3Area of stationary object
If detectors are arranged vertically to maximize radiation incidence area, then radiation detection coverage is improved, but manufacturing and assembly difficulty increases
Solution Approach 1:
The patent incorporates preliminary positioning features directly into the substrate design, such as pre-formed conductive patterns, mounting protrusions, and alignment structures. These preliminary actions are built into the substrate during manufacturing, eliminating the need for complex post-assembly operations to achieve vertical detector orientation, thereby facilitating easier assembly despite the three-dimensional configuration.

AI summary
A radiation detecting apparatus comprises: a first detector that detects incidence of radiation; a plate-shaped detection substrate including a second detector that detects an incident position of the radiation to at least the first detector, and a first terminal that is electrically connected to the second detector; a wiring substrate including a second terminal and an external terminal that is electrically connected to the second terminal; and a connecting member that electrically connects the first terminal and the second terminal. The first terminal is arranged at one end of a main surface of the plate-shaped detection substrate. The detection substrate is mounted on the wiring substrate such that the main surface is substantially perpendicular to the wiring substrate in a state that the one end faces the wiring substrate. The first detector is arranged opposite to the main surface of the detection substrate.
