Solution Overview

Problem

Conventional X-ray detectors face challenges in efficiently installing and replacing modules due to susceptibility to mechanical stress, limited semiconductor area, and lack of mechanisms to prevent breakage or interference during handling and assembly, leading to decreased workability and increased risk of damage.

Innovation Solution

An X-ray detector design featuring a detection module with a protruding frame and a guide frame that allows for precise and easy installation/removal, along with a flexible wiring board and readout circuit substrate connected via high-density signal wirings, and a handle for safe handling, facilitating module replacement while minimizing space and reducing breakage risk.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If modules are arranged on a frame with rails to secure flatness and positioning, then the flatness and relative position of detection modules are improved, but the work load for installing and replacing modules increases significantly

Engineering Contradiction:
Improvepositioning precisionVSAvoidease of module installation
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The frame is divided into multiple guide frames, each capable of independently holding detection modules. This segmentation allows modules to be installed and removed individually without affecting the entire array, reducing the workload while maintaining positioning precision through each guide frame's independent guide grooves

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Guide grooves are introduced as intermediary structures between the frame and detection modules. These grooves provide automatic positioning and guidance during module installation, eliminating the need for manual positioning work while ensuring precise flatness and relative positioning of modules

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of manufacture

If detection elements and readout circuits are bump-bonded with fine solder balls, then the detector can be constructed with separate elements, but the detector becomes susceptible to mechanical impact and scratches

Engineering Contradiction:
Improveease of constructionVSAvoidmechanical robustness
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

A protective structure is provided beforehand to cushion and protect the bump-bonded joints from mechanical impact and scratches. This protective structure absorbs external forces before they reach the fragile solder ball connections, maintaining both the ease of construction from separate elements and the mechanical robustness against damage

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

3Ease of manufacture

If wire bonding is performed on the readout circuit, then the circuit can be connected, but special care must be taken during assembly to avoid damage

Engineering Contradiction:
Improveease of circuit connectionVSAvoidease of assembly
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

Wire bonding is performed as a preliminary action before the final assembly stage. The readout circuits are pre-connected to detection elements through wire bonding while they are in a more accessible state, allowing complex circuit connections to be made beforehand without requiring special care during the final assembly operation

Inventive Principle:
Principle #10Preliminary action

AI summary

To provide an X-ray detector facilitating the installing and replacement work of a module while reducing the possibility of breakage. An X-ray detector 50 detecting X-ray image data for each detection module includes: a detection module 7 provided with a protruding frame on a back side of a detection device detecting X-rays; and a guide frame 12 fitting into the protruding frame and removably supporting the detection device, wherein the guide frame 12 fixes the position of the detection device relative to the guide frame 12 by fitting. Therefore, fitting the protruding frame 8 into the guide frame 12 enables precise and easy installation/removal of the detection module. That is a detection module can be newly installed onto the guide frame without interfering each other with adjacent detection modules already installed while minimizing a space therebetween.
