Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If external light sources (dissecting microscope, endoscope) are used for surgical illumination, then the lighting system can be positioned outside the body, but the illumination intensity in deep surgical cavities becomes insufficient
Solution Approach 1:
The light emitting element is integrated within the outer layer that can be positioned inside the surgical cavity, creating a nested structure where the lighting system is contained within the biocompatible packaging. This allows the light source to be deep within the body while maintaining protection and biocompatibility.
Solution Approach 2:
The outer layer acts as an intermediary between the light emitting element and the surgical cavity environment. It protects the electronic components while allowing light transmission, enabling illumination deep within the body without direct exposure of electrical components to tissue.
2Illumination intensity
If light emitting elements are placed deep within surgical cavities, then illumination visibility improves, but the risk of tissue injury from electrical components increases
Solution Approach 1:
The harmful electrical components are extracted from the surgical environment by enclosing them within the biocompatible outer layer. The light itself is extracted as the useful function while the electrical components remain isolated and protected, eliminating direct contact between electricity and tissue.
Solution Approach 2:
The outer layer serves as an intermediary barrier that separates the light emitting element from direct tissue contact. This biocompatible packaging allows the electrical components to function while preventing harmful interactions with surgical site tissues.
3Device complexity
If conventional external lighting systems are used, then device complexity is reduced, but surgical precision deteriorates due to inadequate lighting
Solution Approach 1:
The lighting function is segmented from the main surgical instrument and integrated as a separate light emitting element within the outer layer. This modular approach allows the lighting system to be independently optimized for precision while maintaining overall system simplicity.
4Illumination intensity
If multiple light emitting elements are deployed, then illumination coverage improves, but device complexity and power requirements increase
Solution Approach 1:
Multiple light emitting elements are merged into a single integrated apparatus with shared power supply and control systems. This combining approach provides broad illumination coverage while minimizing redundant components and reducing overall power consumption compared to multiple separate devices.
