Multiple Module Lamp Concentric Illumination Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surgical operating procedures require adjustable illumination parameters to accommodate different wound types and surgeon positions, which is challenging with lamps providing fixed light distribution.
Innovation Solution
A lighting apparatus with multiple light modules and a controller to create and control concentric illumination zones, allowing for adjustable light intensity and activation states to maintain constant illumination strength across varying operational modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a lamp provides fixed light distribution, then the structure is simple, but it cannot accommodate different surgical scenarios requiring different illumination parameters
Solution Approach 1:
The lamp is divided into multiple independently controllable light modules arranged in concentric zones (central zone, intermediate zone, outer zone). Each zone can be controlled separately to provide different illumination patterns suitable for various surgical scenarios such as deep narrow wounds, large surface wounds, and different surgeon positions.
Solution Approach 2:
The lamp incorporates dynamic control capabilities allowing real-time adjustment of illumination parameters including intensity, color temperature, and zone activation. The control system enables switching between different operational modes and dimming levels to adapt to changing surgical requirements.
2Adaptability or versatility
If different illumination zones are controlled separately, then illumination adaptability improves, but control complexity increases
Solution Approach 1:
The control system is designed to manage multiple illumination zones and operational modes through a unified interface. The controller can store and recall different operational configurations, and provides comprehensive control functions including zone activation, intensity adjustment, and color temperature control through integrated switches and dimming devices.
3Illumination intensity
If light intensity is varied to maintain constant illumination strength, then illumination quality improves, but energy consumption increases
Solution Approach 1:
The system varies light intensity parameters across different zones and operational modes to maintain optimal illumination strength at the surgical site. The control system adjusts the intensity of individual zones and the overall luminous surface to compensate for changes in zone activation, ensuring consistent illumination quality while managing energy consumption.
