Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing charged particle detectors face inefficiencies due to the high number of switching regions and control logics required between adjacent sensing elements, which can lead to increased dead areas and reduced detection performance, particularly when the shape of sensing elements depends on their configuration.
Innovation Solution
The use of triangular-shaped sensing elements and hexagonal sections in the detector array reduces the number of switches and control logics needed, allowing for improved detection performance by conforming better to the shape of the electron beam spot and optimizing the arrangement of signal paths, thereby enhancing the signal-to-noise ratio and simplifying circuit design.

Engineering Contradiction Analysis
1Adaptability or versatility
If square shaped sensing elements are used with four sides, then each sensing element can be connected with adjacent sensing elements on each side, but the number of switching regions increases to four per sensing element, increasing device complexity
Solution Approach 1:
The patent applies asymmetry by changing the sensing element shape from square (4 sides) to triangular (3 sides). This asymmetric modification reduces the number of switching regions from 4 to 3 per sensing element, directly decreasing device complexity while maintaining the essential connection capability through the remaining sides.
Solution Approach 2:
The patent changes the geometric parameter of the sensing element from a quadrilateral (square) to a triangle. This parameter change fundamentally alters the number of sides from 4 to 3, thereby reducing the number of switching regions and control logics required, while still allowing adjacent sensing elements to be connected on each side.
2Adaptability or versatility
If more switching regions are provided between sensing elements, then more connections can be made, but the dead area increases and detection performance decreases
Solution Approach 1:
By using triangular sensing elements with 3 sides instead of square elements with 4 sides, the patent reduces the number of switching regions while minimizing dead area. The asymmetric triangular shape allows for more efficient packing and reduced isolation areas between elements, improving detection performance.
Solution Approach 2:
Changing the geometric parameter from 4-sided to 3-sided elements reduces the total number of switching regions in the array. This parameter change directly reduces the dead area proportion and increases the active detection area, thereby improving detection performance and signal-to-noise ratio.
3Device complexity
If the number of control logics is reduced, then device complexity decreases, but the ability to control switches between sensing elements may be limited
Solution Approach 1:
The triangular geometry with 3 sides naturally reduces the control logic requirements from 4 to 3 per sensing element. The asymmetric shape maintains sufficient control capability by allowing connections on each side while reducing the total number of control signals needed, achieving a better balance between complexity and functionality.
Solution Approach 2:
By changing the geometric parameter from 4-sided to 3-sided elements, the patent reduces the number of control logics required. This parameter change maintains essential control capability through the remaining 3 sides while decreasing overall device complexity and control signal requirements.
