Medical Observation System Light Projection for Capturing Area Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators, such as surgeons, face difficulty in intuitively recognizing the capturing area during medical observations due to the lack of clear visual cues, making it challenging to accurately maneuver the capturing unit.
Innovation Solution
A medical observation system that incorporates a light projection unit to project light patterns outside the capturing area, allowing operators to visually recognize the capturing state and position of the capturing unit, thereby enhancing intuitive understanding and reducing reliance on sensory recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If no light projection is used, then power consumption is low and the system is simple, but operators cannot intuitively recognize the capturing area
Solution Approach 1:
The light projection unit projects light periodically or on-demand rather than continuously. The control unit activates the light projection when the capturing unit is moved or when recognition is needed, and deactivates it when stable observation is sufficient, thereby reducing overall power consumption while maintaining intuitive recognition capability.
Solution Approach 2:
The light projection unit projects light only in the periphery region outside the capturing area, not across the entire observation field. This localized illumination provides visual cues for capturing area recognition while minimizing energy consumption compared to full-field illumination.
2Ease of operation
If light is projected continuously, then capturing area recognition is always clear, but power consumption increases
Solution Approach 1:
The system employs periodic or event-triggered light projection controlled by a control unit. The light is projected when movement of the capturing unit is detected or when the system transitions between observation states, rather than maintaining continuous illumination, thus balancing recognition clarity with energy efficiency.
3Illumination intensity
If illumination light is emitted only in capturing direction, then capturing area is well lit, but peripheral recognition is difficult
Solution Approach 1:
The illumination system is segmented into two functional parts: the light emitting unit that provides primary illumination in the capturing direction for image acquisition, and the light projection unit that projects light in the periphery region to indicate capturing area boundaries and state. This segmentation allows each component to optimize its function without compromising the other.
Solution Approach 2:
The light projection unit acts as an intermediary visual aid between the capturing unit and the operator. It projects light patterns in the periphery that mediate the operator's understanding of the capturing area position and state, complementing the primary illumination without interfering with the captured image quality.
