Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional lighting systems are used in operating rooms, then the basic illumination function is provided, but the Chromaticity Rendering Index (CRI), color temperature, and scialytic effect cannot be optimally reproduced
Solution Approach 1:
The lighting system is divided into multiple independent LED modules, each capable of emitting light at different color temperatures (e.g., 4000K, 5000K, 6000K). These modular segments can be individually controlled to achieve optimal CRI and color temperature for different surgical procedures, resolving the contradiction between providing basic illumination and enabling optimal adjustable lighting quality.
Solution Approach 2:
The system incorporates dynamic control capabilities that allow real-time adjustment of color temperature and brightness levels. The lighting characteristics can be dynamically modified during surgical procedures to match different tissue types and surgical requirements, transforming a static lighting system into an adaptive one that optimizes CRI and scialytic effect.
2Illumination intensity
If multiple LED light sources with multiple reflectors are used to achieve uniform lighting and reduce shadows, then the scialytic effect is improved, but the device complexity increases
Solution Approach 1:
Multiple LED modules are integrated into a single compact housing structure with shared control electronics and power supply. The reflectors are designed as integrated components of the LED assemblies rather than separate elements, reducing the overall number of discrete parts while maintaining the scialytic effect through coordinated light emission from multiple sources.
Solution Approach 2:
The design employs nested concentric rings of LED modules with reflectors positioned within each other. Inner LED rings are surrounded by outer rings, creating a compact nested structure that achieves uniform 360-degree illumination without requiring excessive space or component count. This nested arrangement optimizes the scialytic effect while controlling device complexity.
