Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate endoscopic devices with hardwired cable connections are used to provide color imaging, multispectral imaging, fluorescence imaging, and laser mapping imaging, then comprehensive advanced visualization data can be captured, but the quantity of cables increases leading to clutter and complications during surgical procedures
Solution Approach 1:
The patent combines multiple separate endoscopic devices into a single integrated endoscopic device that houses multiple imaging sensors (color camera, multispectral sensor, fluorescence sensor, mapping sensor) and multiple electromagnetic radiation sources within one unified structure. This merging eliminates the need for multiple separate cable connections while maintaining all advanced visualization capabilities.
Solution Approach 2:
The integrated endoscopic device performs multiple functions through a single device: color imaging, multispectral imaging, fluorescence imaging, and laser mapping imaging. The device includes multiple independently actuatable electromagnetic radiation sources and multiple imaging sensors that can operate simultaneously or sequentially, allowing one device to replace multiple specialized devices.
2Measurement precision
If multiple independently actuatable sources of electromagnetic radiation are used to enable color, multispectral, fluorescence, and laser mapping imaging, then high-definition imaging and advanced visualization are achieved, but the device complexity and number of components increase
Solution Approach 1:
Multiple electromagnetic radiation sources (visible light source, UV source, blue light source, infrared source) and multiple imaging sensors are merged into a single integrated endoscopic device. The sources are arranged in a compact configuration within the endoscope housing, and all components are controlled through a unified control system that coordinates their operation.
Solution Approach 2:
The control system dynamically manages the operation of multiple electromagnetic radiation sources and imaging sensors based on the selected imaging mode. The controller can activate specific sources and sensors in sequence or simultaneously depending on whether color imaging, multispectral imaging, fluorescence imaging, or laser mapping imaging is required, optimizing device operation for each specific function.
