Solution Overview
Problem
Existing radiation imaging apparatuses face challenges in achieving lightness while ensuring mechanical strength and ease of replacing the casing, and they often produce unwanted contact sounds during use.
Innovation Solution
A radiation imaging apparatus with a casing design comprising a front cover, rear cover, and a frame formed of multiple removable and mountable frame members, along with elastic bodies and protrusion portions to enhance mechanical strength and suppress internal contact sounds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the casing is made lightweight to improve portability, then the mechanical strength and resistance to drop impact are reduced
Solution Approach 1:
The casing is constructed using composite materials, specifically a resin material reinforced with inorganic particles (such as aluminum oxide or silicon carbide). This reinforcement provides enhanced mechanical strength and impact resistance while maintaining the lightweight advantage of the resin base material, thus resolving the contradiction between weight reduction and strength enhancement.
Solution Approach 2:
The casing design incorporates local reinforcement at critical areas such as corners and edges that are most susceptible to impact damage. By concentrating the inorganic particle reinforcement and structural support elements at these high-stress locations rather than uniformly throughout the entire casing, the design achieves optimal strength-to-weight ratio, providing necessary protection where needed while minimizing overall weight.
2Strength
If the casing and sensor are integrated to improve structural strength, then the ease of replacement and maintenance is reduced
Solution Approach 1:
The casing is divided into separable components including a front cover, rear cover, and side covers that can be detached from the sensor unit. This segmentation allows the casing parts to be replaced independently for maintenance or upgrade purposes while the sensor unit remains intact, resolving the contradiction between structural strength and ease of replacement.
Solution Approach 2:
A frame structure acts as an intermediary component between the sensor unit and the removable casing covers. This frame provides structural support and connection points for the covers, enabling easy attachment and detachment of casing parts while maintaining overall structural integrity during operation.
3Strength
If protrusion portions are added to support components to increase mechanical strength, then internal contact sounds are generated
Solution Approach 1:
An elastic body is introduced as an intermediary element between the protrusion portions of the supporting member and the casing interior. This elastic body acts as a cushioning layer that absorbs impact forces and prevents direct contact between hard surfaces, thereby eliminating the harmful contact sounds while allowing the protrusion portions to maintain their structural support function.
Solution Approach 2:
The design converts the potential harmful effect of rigid contact (producing unwanted sounds) into a beneficial cushioning effect by using the elastic body. The same protrusion portions that provide structural support now work in conjunction with the elastic cushioning material to create a system that both supports components and suppresses harmful contact noises.
