X-ray Imaging Handle Unit Design for Radio Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable X-ray imaging apparatuses face issues with radio wave interference and state notification obstruction when a shielding substance adheres to the grip member or when the operator grasps the handle, leading to reduced radio wave strength and blocked communication.
Innovation Solution
A radiation imaging apparatus with a detachable handle unit that includes a frame covering three side surfaces of the housing, with a grasping portion forming an opening between the handle and one side surface, positioning the power switch and display unit to prevent interference and ensure accessibility for operation and communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a shielding substance adheres to the grip member or the operator grasps the handle, then the handle provides secure grasping, but radio wave strength is lowered and communication is blocked
Solution Approach 1:
The notification section is extracted from the handle unit and relocated to the housing body. This separation ensures that the notification function is no longer dependent on the handle's position or grasping state, allowing radio communication and state notification to function reliably regardless of whether the handle is being held.
Solution Approach 2:
The housing body serves as an intermediary structure that houses the notification section away from the handle. By positioning the notification section on the housing rather than the handle, the system mediates between the need for secure grasping and reliable communication/notification.
2Loss of information
If the notification section is provided on the handle, then state notification is available, but the notification can be covered when the operator grasps the handle
Solution Approach 1:
The notification section is extracted from the handle unit and relocated to the housing body. This spatial separation ensures that the notification remains visible and accessible even when the operator's hand grasps the handle, as the notification is positioned on the main body rather than on the grasped portion.
Solution Approach 2:
The notification section is repositioned from the handle dimension to the housing body dimension, creating spatial separation in a different dimensional context. This allows the notification to be viewed from angles that are not blocked by the operator's hand grasping the handle.
3Device complexity
If the power switch and display unit are arranged on the housing, then the interface components are integrated, but they become inaccessible or hard to operate when the handle is grasped
Solution Approach 1:
The device is segmented into two functional zones: the handle unit for grasping and the housing body for interface components. By segmenting the placement of components, the power switch and display unit are positioned on the housing in areas that remain accessible even when the handle is firmly grasped, maintaining both integration and operability.
Solution Approach 2:
Different regions of the device are assigned different functions based on their accessibility characteristics. The housing body provides a stable surface for interface components that require visibility and accessibility, while the handle provides a secure grasping surface. This local quality assignment ensures that each component is positioned where it can function optimally.

AI summary
A radiation imaging apparatus includes an imaging unit and a handle unit detachably attached to the imaging unit. The imaging unit includes a digital radiation detector including a detection area, a housing incorporating the digital radiation detector, a power arranged on one side surface of the housing, and a display unit arranged on the one side surface and configured to indicate a state of the digital radiation detector. The handle unit includes a frame unit covering at least part of each of three side surfaces other than the one side surface of the housing and a grasping portion forming an opening between the handle unit and at least part of the one side surface, with the handle unit attached to the imaging unit.
