Solution Overview

Problem

The existing radiation imaging apparatus may damage the sensor panel when inserting and removing rigid members for pressure-bonding wiring members, leading to deformation issues during the process.

Innovation Solution

A method is introduced where a sensor panel with a higher elastic modulus supporting portion is used to inhibit the removal of a second supporting portion, which supports electrical contacts, allowing for pressure-bonding of wiring members without deforming the sensor panel, with the elastic modulus of the supporting portion being higher than the adhesive layer during pressure-bonding.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If rigid members are inserted into gaps between the supporting substrate and sensor panel during pressure-bonding, then deformation of the sensor panel is suppressed, but the sensor panel may be damaged when members are inserted and removed

Engineering Contradiction:
Improvesensor panel deformation suppressionVSAvoidsensor panel damage during member insertion/removal
Core Design Contradiction:
Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The patent changes the physical parameter of the supporting portion by using a second supporting portion with higher elastic modulus than the adhesive layer. This parameter change allows the supporting portion to maintain rigidity during pressure-bonding without requiring insertion of rigid members, thereby suppressing sensor panel deformation while avoiding damage from member insertion and removal operations.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent extracts the function of deformation suppression from the insertable rigid members and integrates it into the second supporting portion through material selection (higher elastic modulus). This eliminates the need for separate rigid members that cause damage during insertion and removal, while maintaining the essential function of preventing sensor panel deformation during pressure-bonding.

Inventive Principle:
Principle #2Taking out (Extraction)

2Stability of the object's composition

If the elastic modulus of the second supporting portion is higher than the adhesive layer, then the sensor panel is suppressed from deforming during pressure-bonding, but the device complexity increases

Engineering Contradiction:
Improvesensor panel deformation suppressionVSAvoidsupporting portion structure complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent merges the function of the second supporting portion into the existing supporting substrate structure. By integrating the deformation suppression function directly into the supporting portion rather than adding separate components, the patent achieves sensor panel stability during pressure-bonding without significantly increasing device complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent achieves deformation suppression through parameter change (elastic modulus selection) of the second supporting portion material rather than through complex structural design. This allows the function to be achieved through material property optimization, keeping the overall device structure relatively simple.

Inventive Principle:
Principle #35Parameter changes

AI summary

A radiation detection apparatus employs a sensor panel having first and second opposing surfaces with a pixel array and electrical contacts arranged on the first surface side. A first supporting portion is secured to the panel with an adhesive layer, and supports the pixel array from the second surface side of the panel. A second supporting portion is fixed to the panel so as to inhibit the second supporting portion from being removed from the panel. The second supporting portion supports the electrical contacts from the second surface side of the panel. The elastic modulus of the second supporting portion is higher than that of the adhesive layer, and a number of wiring members are pressure-bonded to the electrical contacts.
