Radiation Detection Device Spacer Load Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Radiation detection devices face damage due to deformation under load, as the existing designs do not adequately prevent warpage of the base and subsequently the flat panel detector, which can lead to bending and damage of the radiation detection panel.
Innovation Solution
A radiation detection device is designed with a supporting member having a radiation detection panel on one surface and power supply units bonded to the opposite surface, with spacers protruding from the power supply units to contact the housing bottom, distributing the load and preventing warpage by acting as reinforcing members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the base is supported by rechargeable batteries with wide attachment surfaces, then warpage of the base is prevented, but bending occurs along the edge of the attachment surface due to pressing the contact region
Solution Approach 1:
The patent introduces spacers as intermediary elements between the rechargeable batteries and the base. These spacers distribute the pressing force more evenly across the attachment surface, preventing both warpage and edge bending by mediating the contact between the batteries and the base structure.
Solution Approach 2:
The patent applies different structural qualities to different regions of the base. Reinforcing ribs or additional support structures are positioned specifically at high-stress areas such as the edges of battery attachment surfaces, providing localized reinforcement where bending is most likely to occur while maintaining overall base stability.
2Device complexity
If the FPD is directly attached to the base, then the structure is simplified, but the FPD is damaged due to deformation under load
Solution Approach 1:
The patent introduces intermediate supporting structures such as reinforcing ribs or buffer layers between the FPD and the base. These intermediaries absorb and distribute mechanical stresses, protecting the FPD from deformation damage while maintaining a relatively simple overall structure.
Solution Approach 2:
The patent incorporates cushioning elements or flexible buffer layers beneath the FPD before loads are applied. These pre-installed protective elements absorb shock and prevent direct transmission of deformation forces to the FPD, ensuring its reliability under varying load conditions.
3Force
If two rechargeable batteries are provided on diagonal lines of the base, then load distribution is improved, but bending in the outer periphery of each battery attachment surface is not prevented
Solution Approach 1:
The patent enhances local structural quality at the periphery of battery attachment surfaces by adding reinforcing ribs, edge supports, or localized stiffening elements. This targeted reinforcement prevents bending at vulnerable edge regions while maintaining the diagonal battery arrangement for good load distribution.
Solution Approach 2:
The patent employs composite construction techniques, combining materials with different mechanical properties in the base structure. For example, using high-stiffness materials or reinforced composite layers specifically at the periphery of battery attachment areas provides enhanced resistance to bending while maintaining overall structural integrity and load distribution.
