X-ray tube gripping portion center of gravity balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable X-ray tube devices with heavy components are difficult for users to support using a single gripping portion due to uneven center of gravity, making it hard to maintain a necessary posture for operation.
Innovation Solution
Designing an X-ray tube device with a single gripping portion positioned on the center-of-gravity-side portion, where the center of gravity is ideally between the front and rear surfaces, and the battery's center of gravity on the non-center-of-gravity-side portion, allowing the device to be supported easily by gripping one handle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If gripping portions are provided on both right and left sides of the main body, then the X-ray tube device can be supported by human power during use, but the device complexity increases and the ease of operation deteriorates due to requiring two-handed support
Solution Approach 1:
The invention extracts only one gripping portion from the conventional two-grip design, placing it specifically in the center-of-gravity-side portion. This allows the device to be supported with one hand while maintaining balance, eliminating the need for the second gripping portion on the non-center-of-gravity side.
Solution Approach 2:
The invention applies asymmetry by positioning the single gripping portion exclusively in the center-of-gravity-side portion rather than symmetrically distributing grips on both sides. This asymmetric placement optimizes the balance between the user's hand and the device's center of gravity, enabling stable one-handed support.
2Volume of moving object
If the center of gravity is not at the center of the X-ray tube device, then the device can be compactly designed, but it becomes particularly hard for the user to support the device by gripping one gripping portion
Solution Approach 1:
The invention applies local quality by concentrating the gripping function specifically in the center-of-gravity-side portion where the mass is located. The gripping portion is designed with appropriate size and shape to provide sufficient friction and support, while other portions of the device maintain their compact design without additional gripping features.
3Device complexity
If gripping portion is placed in the non-center-of-gravity-side portion, then the device structure is simplified, but the user cannot easily maintain the necessary posture for operation
Solution Approach 1:
The invention positions the gripping portion in the center-of-gravity-side portion to create a counterbalancing effect. When the user grips this portion, their hand acts as a counterweight that balances the device's center of gravity, allowing easy maintenance of the necessary operating posture without requiring additional structural complexity.

AI summary
An X-ray tube device incorporates a mono-tank, and includes a gripping portion that is provided to protrude from a main body in a side surface and supports the main body by gripping. In a case where the main body is divided into two portions of a center-of-gravity-side portion including the center of gravity of the main body and a non-center-of-gravity-side portion not including the center of gravity using a plane passing through the center of the main body and an irradiation direction of X-rays, the gripping portion is in the center-of-gravity-side portion, and the gripping portion is not in the non-center-of-gravity-side portion.
