Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable X-ray imaging apparatuses face challenges in achieving sufficient mechanical strength without increasing external size, weight, or thickness, which is crucial for preventing damage from drops and ensuring image quality.
Innovation Solution
The apparatus incorporates a recessed structure at the connection portion of the front and rear casings, made of lightweight materials like aluminum or magnesium, with a supporting member and buffer sheet to absorb impact, and a gripping portion for improved portability, while maintaining a thin profile to reduce physical contact with subjects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the apparatus is made thinner to reduce physical contact with subjects, then comfort is improved, but mechanical strength and resistance to dropping deteriorate
Solution Approach 1:
The casing is divided into front and rear casings connected by a connection portion. The recess at the connection portion creates a structural feature that distributes impact forces during dropping, allowing the overall apparatus to remain thin while gaining enhanced mechanical strength at critical stress points.
2Weight of moving object
If the apparatus weight is reduced to less than 2.5 kg for portability, then ease of carrying is improved, but impact energy during dropping increases
Solution Approach 1:
A buffer material is incorporated into the connection portion of the casing to absorb impact energy before it reaches sensitive internal components. This cushioning structure is built-in from the beginning, allowing the apparatus to remain lightweight while protecting against dropping impacts.
3Strength
If a protection frame is attached to the outside of the casing to increase strength, then mechanical strength is improved, but the external size and weight of the apparatus increase
Solution Approach 1:
The protective function is merged into the casing structure itself through the recessed connection portion design. Instead of adding a separate protection frame, the casing geometry itself provides the protective function, maintaining compact external dimensions while enhancing strength.
Solution Approach 2:
The connection portion uses a composite structure combining the casing material with buffer material to achieve both lightweight construction and impact resistance. This composite approach provides mechanical strength without requiring additional external framing structures.
