Radiological Imaging Device Controller Weight Balancing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Radiographic image capturing apparatuses with electronic cassettes face challenges in stable carrying due to unbalanced weight distribution caused by centralized and heavy power supplies and communication units, leading to potential damage from impacts during use.
Innovation Solution
The apparatus features a controller that is thicker than the panel unit or protrudes from it, allowing for translation or rotation along the panel unit's surface, which adjusts the center of gravity to balance the device, and includes a moving mechanism to reposition the controller outside the image capturing area, minimizing weight imbalance and obstacles during image capture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the power supply and communication unit are centralized in a certain area of the controller, then the controller can be compactly designed, but the weight distribution of the electronic cassette becomes unbalanced
Solution Approach 1:
The controller is designed to be movable along the panel unit surface, allowing dynamic repositioning to balance weight distribution. The moving mechanism enables the controller to shift its position, transforming a static weight imbalance into a dynamically adjustable configuration that achieves stable weight distribution during carrying.
2Device complexity
If the controller is made thicker or protruding to house power supply and communication unit, then these components can be integrated, but the controller may obstruct the image capturing area
Solution Approach 1:
The controller's position is made dynamic through the moving mechanism, allowing it to be repositioned to protrude from the panel unit in directions that do not obstruct the image capturing area. This enables the controller to maintain its integrated form while adapting its spatial relationship to the imaging zone.
Solution Approach 2:
The controller is designed to move along the surface of the panel unit, utilizing the two-dimensional surface space rather than occupying three-dimensional space within the image capturing area. This dimensional approach allows the controller to be positioned on the panel surface without blocking the imaging path.
3Adaptability or versatility
If the controller is made heavier to include power supply and communication unit, then the electronic cassette gains necessary functionality, but the electronic cassette feels heavier and is harder to carry
Solution Approach 1:
The moving mechanism acts as a counterbalancing system, allowing the heavy controller to be repositioned to optimize the center of gravity. By adjusting the controller's position, the system compensates for the weight imbalance caused by the heavy power supply and communication unit, making the electronic cassette feel lighter and easier to carry.
