Radiation Imaging Light Source Back Surface Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional radiation imaging apparatuses face issues with increased weight and reduced portability due to the placement of light sources indicative of the apparatus's state between the radiation detection panel and the housing side surface, which enlarges the housing frame size and complicates connection verification.
Innovation Solution
The radiation imaging apparatus incorporates a light source within the housing's back surface, projecting the radiation detection panel's outer shape, allowing for visual confirmation of the apparatus's state without enlarging the frame size, and includes a light guide lens and LED light source to indicate connection status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the light source is disposed between the radiation detection panel and the side surface of the housing, then the state of the radiation imaging apparatus can be viewed from the side surface direction, but the frame size of the housing becomes considerably larger and the weight increases
Solution Approach 1:
The light source is repositioned from the side surface to the back surface of the housing, changing the spatial dimension of light emission. This allows the light to emit toward the back surface direction rather than the side surface, enabling state visibility without increasing the housing frame size in the lateral direction.
Solution Approach 2:
Instead of emitting light toward the side surface as in conventional designs, the light source emits light toward the back surface of the housing. This inverted emission direction allows the state indicator to be visible from the back surface side, resolving the contradiction between visibility and compactness.
2Ease of operation
If the light source is disposed between the radiation detection panel and the side surface of the housing, then the state can be viewed from the side surface, but the portability of the radiation imaging apparatus deteriorates
Solution Approach 1:
The light emission direction is changed from side surface to back surface, allowing the state indicator to be visible without increasing the lateral dimensions of the housing. This maintains the compact form factor required for portability while still providing visual feedback on the apparatus state.
3Ease of operation
If the connection terminals are disposed at the back of the insertion portion, then a means for confirming proper connection should be disposed on the opposite side surface, but conventional light source placement on the side surface creates conflicts
Solution Approach 1:
The light source emission direction is inverted to face the back surface where the connection terminals are located. This allows the light to indicate connection status on the same side as the terminals, eliminating the need for additional structural complexity to provide visual feedback on the opposite side.
