Hinge Mechanism Positioning in Foldable Ultrasonic Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In foldable ultrasonic diagnosis apparatuses with touch panels, the hinge mechanism positioning and strength are compromised, leading to instability and increased noise interference from internal components like the power source and CPU board on the image processing circuit board.
Innovation Solution
A supporting section within the main body optimizes the hinge mechanism's position and strength by partitioning internal spaces to isolate noise sources, using a 2-shaft hinge mechanism that allows horizontal rotation and vertical opening/closing, and positions the image processing circuit board at the front while placing the power source and CPU board at the rear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the hinge mechanism position is arranged at the rear end of the main body, then the display section can be connected to the main body, but the front end of the main body floats up when the touch panel is pushed
Solution Approach 1:
The hinge mechanism is positioned at the rear end of the main body, utilizing the longitudinal dimension to create a lever arm that counteracts the floating effect. By placing the hinge at the rear rather than the center or front, the structural weight distribution creates a stabilizing moment that prevents the front end from lifting during touch panel operation.
2Stability of the object's composition
If the hinge mechanism fastening force is set stronger to prevent display section movement, then the display section remains stable, but the front end of the main body floats up
Solution Approach 1:
The hinge mechanism is positioned at the rear end of the main body, utilizing the longitudinal dimension to create a lever arm that counteracts the floating effect. By placing the hinge at the rear rather than the center or front, the structural weight distribution creates a stabilizing moment that prevents the front end from lifting during touch panel operation.
3Stability of the object's composition
If the hinge mechanism position is shifted to the front end from the rear end, then the front end floating problem is solved, but the strength of the main body becomes insufficient
Solution Approach 1:
The hinge mechanism is positioned at the rear end of the main body, utilizing the longitudinal dimension to create a lever arm that counteracts the floating effect. By placing the hinge at the rear rather than the center or front, the structural weight distribution creates a stabilizing moment that prevents the front end from lifting during touch panel operation.
4Device complexity
If various circuit boards are arranged inside the main body without partitioning, then the device complexity is reduced, but noise from power source and CPU board affects the image processing circuit board
Solution Approach 1:
The main body's internal space is divided into multiple regions using partition walls. The image processing circuit board is placed in a first region while the power source and CPU board are placed in a second region. This segmentation physically separates noise-generating components from sensitive components, reducing electromagnetic interference without significantly increasing overall device complexity.

AI summary
A technique which in a portable or laptop ultrasonic diagnosis apparatus, optimizes the position of a hinge mechanism for connecting a display section having a touch panel and a main body and the strength of the main body and also reduce the influence of noise between mutual sections, such as an ultrasonic image processing circuit board, a power source, a CPU board and the like, which are arranged inside the main body is disclosed. According to this technique, on a bottom surface of a bottom case 11 in the main body, a supporting section 12 for supporting a display section 20 is formed to stand upright and extend in a width direction, at a position that is dislocated to a front end F side from a rear end R of a main body 10. Also, a region A in which the ultrasonic image processing circuit board is arranged and regions B, C in which a power source unit and the CPU board are arranged, respectively, are partitioned by means of the supporting section 12.
