Ultrasonic Diagnostic Device Handle Locking for Transport Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ultrasonic diagnostic devices with handles face issues during transport, such as free rotation angles leading to collisions and potential contamination of the grip when used as a stand, especially at inclined angles greater than 5 or 10 degrees.
Innovation Solution
Incorporation of a hinge mechanism with a handle locking mechanism that locks the handle at a first rotation angle during transport and a second rotation angle when used as a stand, featuring arms with bent portions to maintain grip cleanliness and reduce interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the handle is allowed to rotate freely, then the ultrasonic diagnostic device can be easily adjusted to different positions, but the main body unit may collide with other objects during transport when suspended at large inclined angles
Solution Approach 1:
The handle is designed with a hinge mechanism that allows dynamic rotation between a first rotation angle for transport and a second rotation angle for use. The locking mechanism enables the handle to be fixed at appropriate angles, providing both adjustability and stability as needed.
Solution Approach 2:
The rotation angle of the handle is changed between two specific states: a first rotation angle when the main body unit is suspended during transport, and a second rotation angle when the main body unit is placed on a surface during use. This parameter change resolves the contradiction by adapting the handle position to different operational requirements.
2Stability of the object's composition
If the handle functions as a stand with large inclined angle, then the main body unit can be properly positioned for use, but the grip may contact the table surface and become contaminated
Solution Approach 1:
The handle is divided into two functional parts: the grip portion for user contact and the arm portion that contacts the table surface when functioning as a stand. This segmentation allows the grip to be positioned away from contaminated surfaces while maintaining the stand function through the arm structure.
Solution Approach 2:
The handle arms are extended outward from the main body unit in a horizontal dimension, allowing the grip to be positioned in a different spatial plane away from the table surface. This dimensional arrangement enables the handle to function as a stand while keeping the grip elevated and clean.
3Reliability
If the handle is locked at a fixed rotation angle, then the main body unit is stabilized during transport, but the handle cannot be adjusted for different usage scenarios
Solution Approach 1:
The hinge mechanism with locking capability provides dynamic adaptability: the handle can be locked at a first rotation angle for stable transport, unlocked for adjustment, and locked at a second rotation angle for use as a stand. This dynamic system resolves the contradiction between stability and versatility.
Solution Approach 2:
The handle is designed to perform multiple functions by locking at different rotation angles: it serves as a transport handle when locked at the first angle and as a support stand when locked at the second angle. This multi-functionality resolves the contradiction between fixed stability and adaptive versatility.

AI summary
In a case where a main body unit is transported by gripping a grip of a handle, the main body unit is protected. In addition, cleanliness of the grip is maintained. A main body has a hinge mechanism. A handle is connected to the hinge mechanism. The hinge mechanism has a handle locking mechanism. The handle locking mechanism locks the handle at a first rotation angle or a second rotation angle. In a case where the handle is used as a stand, a grip does not come into contact with a placement surface.
