Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical lighting systems in labor and delivery rooms often fail to provide optimal illumination, leading to issues such as shadows, glare, and uneven light distribution, which can hinder medical procedures by not effectively balancing ambient and focused light.
Innovation Solution
A medical illumination system that includes a light source with modulable properties, such as spot size, position, focus, and brightness, controlled by processor circuitry and optical components like deformable lenses or liquid crystals, to dynamically adjust and optimize the illuminated area, minimizing shadows and glare.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If standard operating room lights are used to illuminate the operating room during procedures, then ambient illumination is provided, but focused illumination at specific operative stages and angles is insufficient
Solution Approach 1:
The patent combines multiple light sources (headlight and operating room lights) into a unified illumination system that can operate independently or synergistically. The headlight provides focused illumination while the operating room lights provide ambient illumination, and the system can switch between or combine these modes to achieve both focused and ambient illumination requirements simultaneously.
Solution Approach 2:
The illumination system is designed to perform multiple functions: providing focused illumination, ambient illumination, and dynamic adjustment of light properties. The system can adapt to different surgical stages and angles by modulating the light output of individual sources, making a single system versatile enough to handle various illumination needs without requiring separate dedicated devices.
2Illumination intensity
If brighter light is applied to illuminate the surgical area, then illumination intensity increases, but glare and eye strain increase
Solution Approach 1:
The system applies different light qualities to different areas and purposes: the headlight provides high-intensity focused illumination for the immediate surgical field, while the operating room lights provide lower-intensity ambient illumination. This local differentiation allows the system to maintain high brightness where needed without creating excessive glare in the broader environment, as each light source is optimized for its specific function.
Solution Approach 2:
The illumination system dynamically adjusts light properties including intensity, color temperature, and direction based on the surgical stage and anatomical region being operated on. The system can modulate the output of individual light sources in real-time to optimize illumination while minimizing harmful effects like glare and eye strain, adapting the lighting characteristics to match the specific needs of each surgical moment.
3Measurement precision
If light is focused on a specific area, then illumination precision improves, but shadows caused by obstructions increase
Solution Approach 1:
The illumination system divides the lighting function into separate segments: a headlight for focused illumination and operating room lights for ambient illumination. This segmentation allows the focused light to illuminate the immediate surgical field with precision while the ambient lights illuminate the surrounding area, reducing shadows cast by obstructions in the broader field of view. Each light source can be independently controlled to optimize its specific function.
Solution Approach 2:
The operating room lights act as an intermediary illumination layer that fills in shadowed areas created by the focused headlight. When obstructions block the headlight, the ambient operating room lights provide supplementary illumination to the surrounding areas, effectively mediating the shadow problem while preserving the focused illumination precision where needed.
