Adaptive Operating Room Illumination Device Shadow Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing illuminating devices for operating rooms suffer from cast shadows due to the surgeon's body parts obstructing the light path, leading to inadequate illumination and increased costs and space requirements for broader devices to mitigate this issue.
Innovation Solution
An illuminating device with at least two light modules and a sensor device for detecting depth information, which monitors the volume between the light modules and the illuminated area, adjusts light intensity based on detected objects to minimize shadowing by correlating object data with beam paths and modifying light output accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the illuminating device is made broader to avoid shadow formation, then shadow formation is reduced, but device complexity and cost increase
Solution Approach 1:
The patent applies dynamics by making the light intensity of individual light modules adjustable and modifiable in real-time. The control unit dynamically changes the light intensity parameters of individual modules based on detected shadow conditions, allowing a compact device to adapt its illumination pattern to compensate for shadows without requiring a physically larger structure.
Solution Approach 2:
The patent changes the parameter of light intensity for individual light modules based on detected shadow conditions. The control unit modifies the intensity parameters of specific modules whose beam paths are obstructed, allowing the system to compensate for shadows through parameter adjustment rather than structural expansion.
2Object-affected harmful factors
If the illuminating device is made broader to avoid shadow formation, then shadow formation is reduced, but space requirements increase
Solution Approach 1:
The system uses dynamic control of light intensity parameters to compensate for shadows, eliminating the need for a physically larger device footprint. The compact illuminating device achieves broad coverage by intelligently adjusting which modules are active and at what intensity levels.
Solution Approach 2:
By changing the light intensity parameters of individual modules based on shadow detection, the system achieves the illumination coverage of a larger device while maintaining a compact physical structure.
3Object-affected harmful factors
If the illuminating device is made broader to avoid shadow formation, then shadow formation is reduced, but manufacturing cost increases
Solution Approach 1:
The patent employs dynamic control of light intensity parameters managed by a control unit, which is a cost-effective solution compared to manufacturing physically larger devices. The added complexity is electronic/software-based rather than structural, significantly reducing manufacturing costs.
Solution Approach 2:
The system achieves shadow compensation through parameter changes in light intensity rather than structural changes, which is much more cost-effective to manufacture and implement.
4Object-affected harmful factors
If the illuminating device is made broader to avoid shadow formation, then shadow formation is reduced, but operability deteriorates
Solution Approach 1:
The system dynamically adjusts light intensity parameters in real-time based on shadow detection, providing adaptive illumination that maintains high operability. The automated control eliminates the need for manual repositioning or adjustment that would be required with larger, fixed illumination devices.
Solution Approach 2:
The system uses feedback from shadow detection to automatically adjust light intensity parameters, improving operability by eliminating manual intervention. The control unit continuously monitors and adapts the illumination based on detected conditions.
