MgLi Alloy Support Plate for Radiation Detection Weight Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Radiation detection devices face challenges in achieving both weight reduction and deformation suppression for their support plates, as existing configurations using aluminum or magnesium alloys struggle to balance these requirements.
Innovation Solution
A radiation detection device featuring a support plate made of MgLi alloy, with tubular support posts and reinforcing ribs, is designed to distribute external loads effectively and reduce weight by using a magnesium lithium alloy with lower specific gravity and stiffness, and forming support posts in a hexagonal shape to enhance structural integrity.

1Weight of moving object
If an aluminum alloy or magnesium alloy is used as a support plate, then weight reduction is achieved, but deformation suppression becomes difficult
Solution Approach 1:
The patent applies composite materials by combining MgLi alloy with a specific structural configuration (support posts and reinforcing ribs) to achieve both weight reduction and deformation suppression. The MgLi alloy provides lighter weight compared to traditional aluminum alloys, while the integrated support posts and reinforcing ribs compensate for the reduced material strength, creating a composite structure that resolves the contradiction between weight and strength.
Solution Approach 2:
The support plate is segmented into multiple functional components: the base MgLi alloy plate, multiple support posts distributed across the plate, and reinforcing ribs. This segmentation allows each component to perform its specific function - the base provides weight reduction, the support posts provide localized strength, and the reinforcing ribs provide additional structural support - thereby resolving the contradiction between overall weight reduction and localized deformation resistance.
2Weight of moving object
If the support plate is made thinner to reduce weight, then portability is improved, but the ability to protect the radiation detection panel from local load deteriorates
Solution Approach 1:
The patent applies local quality by concentrating structural reinforcement at specific locations where loads are most likely to occur. The support posts are positioned at strategic points to provide localized support against local loads, while the reinforcing ribs add strength at critical areas. This allows the majority of the plate to remain thin for weight reduction, while specific local areas have enhanced protection capability.
Solution Approach 2:
The composite structure combines a thin MgLi alloy base plate with strategically placed support posts and reinforcing ribs. This composite approach allows the overall plate to be thin and lightweight while providing robust protection at critical locations where the support posts and ribs are positioned, thus resolving the contradiction between thinness for portability and protection capability.

AI summary
There is provided a radiation detection device capable of realizing both suppression of deformation and weight reduction of a support plate to which a radiation detection panel is fixed. A radiation detection device includes: a radiation detection panel that detects radiation; a support plate which is formed of a MgLi alloy and to which the radiation detection panel is fixed in contact with the support plate; a plurality of tubular support posts that are formed in contact with a surface of the support plate not facing the radiation detection panel; and a housing (rear surface member) in which the radiation detection panel, the support plate, and the support posts are housed and which is disposed in contact with the support posts.
