Display Hinge Center of Gravity Tilting Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional supporting devices for display devices, such as those used with ultrasonic imaging apparatuses, face challenges in compensating for tilting caused by multi-joint arms, leading to user discomfort and increased manufacturing costs due to the need for additional material reinforcement and correction angles.
Innovation Solution
A supporting device with a multi-joint arm featuring a hinge connected to the display device, a damper to restrict rotation, and a brake to fix the hinge, where the hinge is positioned on the same plane as the display device's center of gravity, allowing the weight of the device to stop rotation and a controller to manage the brake's operation based on external forces sensed by a touch or switch sensor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the hinge is disposed above the center of gravity of the display device, then the rotation of the hinge can be stopped by the weight of the display device, but tilting compensation is not effective
Solution Approach 1:
The hinge is positioned at the same vertical level as the center of gravity of the display device, creating a gravitational equipotential condition. This allows the weight of the display device to naturally counterbalance tilting forces without requiring additional stopping mechanisms, achieving both stable positioning and effective tilting compensation simultaneously
2Ease of operation
If additional material reinforcement is added to compensate for tilting, then tilting compensation is improved, but manufacturing costs increase
Solution Approach 1:
The display device's own weight is utilized as the compensating force for tilting. By positioning the hinge at the center of gravity level, the system uses its inherent gravitational force to automatically counterbalance tilting, eliminating the need for additional reinforcing materials or complex correction mechanisms
3Speed
If the damper restricts rotation to shorten rotation time, then response speed is improved, but the natural tilting compensation may be affected
Solution Approach 1:
The damper provides partial restriction on rotation, controlling the speed of movement without completely preventing it. This allows the hinge to rotate quickly enough for user comfort while still permitting the weight-based tilting compensation mechanism to function effectively, achieving a balanced compromise between speed and stability
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution effectively compensates for tilting at all positions without additional material reinforcement, improving user comfort and reducing manufacturing costs by using the display device's weight to stabilize the position and the damper to minimize rotation time, while the brake ensures the display remains fixed when desired.
Implementation Method 1
a damper to restrict rotation of the hinge to a certain extent to shorten a rotation time of the hinge when the hinge is rotated
Implementation Method 2
the hinge is disposed on the same plane as the center of gravity of the display device in a vertical direction of the display device... such that the rotation of the hinge is stopped by the weight of the display device
