Ultrasound Display Handle Restraint for Transport Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ultrasonic diagnosis devices face challenges in securely stopping the movement of large flat panel displays during transportation and maintenance, requiring complex mechanisms that increase costs and complexity.
Innovation Solution
A simple mechanism using a display unit restraint mechanism that holds the handle of the display unit in place, allowing the display unit to be securely positioned and oriented without needing to lock multiple arm mechanism movements, utilizing a rod-like handle and a cover member to prevent removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mechanism is provided to stop movement at each movable portion of the arm mechanism, then the movement of the display unit can be completely stopped, but the device structure becomes complicated and costs increase
Solution Approach 1:
The patent extracts the essential function of stopping display unit movement by focusing solely on restraining the handle, rather than implementing complex locking mechanisms at each movable portion of the arm mechanism. This extraction approach achieves the necessary stability while dramatically simplifying the overall mechanism.
Solution Approach 2:
Instead of locking the arm mechanism components to indirectly stop display unit movement, the patent inverts the approach by directly restraining the handle of the display unit itself. This inversion allows the display unit to be held in position without interfering with the complexity of the arm mechanism.
2Reliability
If a complex mechanism with multiple locking components is used to stop display unit movement, then complete movement control is achieved, but manufacturing costs increase
Solution Approach 1:
The patent extracts only the essential restraining function needed to stop display unit movement, eliminating unnecessary locking components at each arm mechanism joint. This focused approach reduces part count and manufacturing complexity while maintaining adequate position stability.
Solution Approach 2:
The patent employs a simple, inexpensive handle restraint mechanism rather than expensive, complex locking systems. The restraint mechanism uses basic mechanical components that are cost-effective to manufacture while still achieving the desired function of preventing unauthorized movement during transportation.
3Reliability
If the arm mechanism is locked to stop display unit movement, then movement is prevented, but the structure requires multiple locking components increasing device complexity
Solution Approach 1:
The patent inverts the conventional approach by not locking the arm mechanism components, but instead directly restraining the handle of the display unit. This alternative approach achieves the same functional goal of preventing movement while avoiding the complexity of multiple locking components in the arm mechanism.

AI summary
An ultrasonic diagnosis device wherein, in order to reliably stop the movement of a display unit by a simple mechanism during transportation of the device, a display unit restraint mechanism is provided with: a fixed portion which has a receiving groove for receiving a handle main unit provided on the display unit; and a rotation portion which moves rotationally in relation to the fixed portion. When the rotation portion is rotated with the handle main unit received in the receiving groove, the upper side of the handle main unit becomes covered with a cover portion. In this state, a hook member protrudes outward from the rotation portion and is engaged with an upper end portion to serve as a strut.
