Flexible Radiation Detector Support for Edge Deformation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Radiation detection panels in flexible substrates are prone to deformation, which can concentrate loads on connection sections, leading to potential breakage, especially when using flexible printed wiring boards, and existing solutions like reinforcing members and resin filling increase weight and complexity.
Innovation Solution
A radiation imaging apparatus design that includes a flexible substrate with a support base, a bonding member, and a wiring member, where the edge portion of the substrate is supported by an interposed member with higher rigidity than an elastic member, reducing local deformation during vibrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If a flexible substrate is used for the radiation detection panel, then the weight is reduced and durability against deformation is improved, but the panel becomes vulnerable to local deformation and connection section breakage
Solution Approach 1:
The patent applies local quality by providing support bases at specific locations (edge portions and central region) rather than uniform support across the entire panel. The support bases are strategically positioned at corners or edge portions and in the central region to prevent local deformation without requiring a heavy rigid substrate throughout. This localized support approach maintains the flexibility and light weight of the flexible substrate while preventing deformation at critical areas.
2Stability of the object's composition
If a high-rigidity reinforcing member is attached to the entire surface of the flexible substrate, then local deformation is reduced, but the weight of the radiation imaging apparatus increases
Solution Approach 1:
Instead of attaching a reinforcing member to the entire surface, the patent uses support bases at specific locations (edge portions and central region). This localized approach provides necessary structural stability while minimizing the addition of weight, as only discrete support points are added rather than a comprehensive rigid layer.
Solution Approach 2:
The support structure is segmented into multiple discrete support bases rather than a single continuous reinforcing member. The support bases are positioned at edge portions and central regions, creating a segmented support system that provides stability while maintaining flexibility and reducing weight compared to a full-surface rigid reinforcement.
3Stability of the object's composition
If resin is injected to fill the gap between the radiation detection panel and support base, then deformation is reduced, but the flexible substrate may remain vulnerable to deformation and connection section loads
Solution Approach 1:
The patent positions support bases at critical locations (edge portions and central region) to provide localized support where deformation is most likely to occur. This targeted approach is more effective than uniform resin filling, as it addresses the specific areas prone to deformation while maintaining connection reliability.
Solution Approach 2:
The support bases act as intermediary elements between the flexible substrate and the housing, providing mechanical support and distributing loads. These support bases serve as mediators that prevent direct transmission of deformation forces to the connection sections, thereby protecting the flexible printed wiring board connections.
4Stability of the object's composition
If the flexible substrate is fixed in a warped state, then deformation is reduced, but loads are concentrated on the connection section between the flexible substrate and flexible printed wiring board
Solution Approach 1:
The support bases are positioned at edge portions and central regions to provide localized support that maintains substrate flatness without creating warping. This distributed local support prevents the substrate from warping while avoiding concentration of loads on any single connection section.
Solution Approach 2:
The support bases are pre-installed in predetermined positions (edge portions and central region) before the flexible substrate is fully assembled. This preliminary positioning ensures that the substrate is supported at critical points from the beginning, preventing warping and load concentration on connection sections during operation.

AI summary
A radiation imaging apparatus includes a radiation detection sensor, a support base, a bonding member, and a wiring member. The radiation detection sensor is configured to detect radiation and is formed using a flexible substrate. The support base supports radiation detection sensor. The bonding member bonds a first region of the radiation detection sensor to the support base. The first region is located in a central portion of the radiation detection sensor. The wiring member is connected to a predetermined edge portion of the radiation detection sensor. A second region is a region of the radiation detection sensor that includes the predetermined edge portion, and the second region opposes the support base but is not adhered to the support base.
