Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable radiation image detection devices are susceptible to local impacts due to unexpected drops or falls, which can cause deformation and damage to the radiation detection panel, necessitating effective protection measures.
Innovation Solution
A radiation detection device design featuring a double-frame structure with outer and inner ribs, connected by corner portion connection ribs, forming a truss structure, along with a support plate bonded to the rear surface member, enhances the stiffness and protection of the radiation detection panel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a simple housing structure is used for portability, then ease of operation is improved, but the radiation detection panel becomes vulnerable to impact damage
Solution Approach 1:
The housing is segmented into multiple functional components: front surface member, rear surface member with double-frame structure, support plate, and cushioning member. This segmentation allows each component to serve specific protective functions while maintaining overall portability.
Solution Approach 2:
A cushioning member is provided between the radiation detection panel and the rear surface member to absorb impact energy before it reaches the panel. This beforehand cushioning protects the panel during unexpected drops or impacts while keeping the device portable.
2Strength
If the rear surface member is made thicker for protection, then strength is improved, but weight increases affecting portability
Solution Approach 1:
The rear surface member uses a composite structure combining a rigid double-frame (outer rib and inner rib) with a cushioning member. This composite approach provides high strength and impact resistance without requiring excessive thickness, thereby controlling weight for portability.
3Stability of the object's composition
If a double-frame structure with ribs is added to the rear surface member, then stiffness is improved, but device complexity increases
Solution Approach 1:
The double-frame structure is segmented into an outer rib and an inner rib, with the cushioning member positioned between them. This segmentation provides enhanced stiffness and protection while allowing each component to be manufactured and assembled separately, managing overall complexity.
