Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If holographic endoscopes use adaptive optical elements to create controllable three-dimensional focus, then three-dimensional imaging capability is achieved, but device complexity and cost increase significantly
Solution Approach 1:
The patent extracts the 3D imaging function from complex adaptive optical elements and implements it through a simplified multifilament conductor structure. The multifilament conductor transmits light from multiple points simultaneously, enabling 3D reconstruction without requiring adaptive lenses or complex optical components, thus reducing device complexity while maintaining the 3D focus control capability.
Solution Approach 2:
The patent uses a multifilament conductor that acts as a distributed array of optical fibers to copy and transmit light information from multiple spatial points. This allows the system to capture three-dimensional information by transmitting light from multiple points through the conductor to a camera, eliminating the need for complex adaptive optical elements while achieving 3D imaging.
2Adaptability or versatility
If holographic endoscopes use adaptive optical elements for three-dimensional imaging, then imaging capability is improved, but acquisition and maintenance cost increase
Solution Approach 1:
The patent employs a multifilament conductor made from standard optical fibers that can be manufactured cost-effectively. The simplified structure using conventional optical components (multifilament conductor, camera, processor) replaces expensive adaptive optical elements, reducing both acquisition and maintenance costs while maintaining 3D imaging capability.
Solution Approach 2:
The patent changes the approach from using expensive adaptive optical elements to using a fixed multifilament conductor structure. By transmitting light through multiple optical fibers and processing the information computationally, the system achieves 3D imaging with lower-cost hardware, reducing both acquisition and maintenance expenses.
3Length of moving object
If the endoscope diameter is reduced to less than 1 mm for brain endoscopy, then accessibility to small openings is improved, but optical performance and focus control become more difficult to achieve
Solution Approach 1:
The patent divides the optical transmission function into multiple separate optical fibers within the multifilament conductor. Each fiber transmits light from a specific point, allowing the system to maintain focus control by selectively activating and processing light from different fibers, thereby achieving 3D imaging with a diameter of less than 1 mm.
Solution Approach 2:
The patent transitions from traditional two-dimensional imaging to three-dimensional imaging by using the multifilament conductor to transmit light from multiple spatial points simultaneously. This allows the system to achieve focus control in three dimensions without increasing the endoscope diameter, as the 3D information is encoded in the spatial distribution of light across the multiple fibers.
4Object-affected harmful factors
If traditional cameras are used for three-dimensional imaging, then electromagnetic compatibility is maintained, but the ability to achieve three-dimensional focus control is lost
Solution Approach 1:
The patent replaces traditional mechanical optical focus control mechanisms with a computational approach. The multifilament conductor transmits light information to a camera and processor, which then reconstructs three-dimensional images through computational methods, eliminating the need for mechanical focus adjustment while maintaining electromagnetic compatibility.
