Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional mechanical optical elements are used for focusing and zooming, then the device structure is simple, but the adjustment process is time-consuming and inaccurate
Solution Approach 1:
The patent replaces traditional mechanical focusing and zooming mechanisms with digital image processing. The processor captures images at different focal planes or zoom levels and computationally combines them to achieve the desired magnification and focus, eliminating the need for precise mechanical adjustments and reducing adjustment time.
Solution Approach 2:
The system pre-captures multiple images at different focal planes or zoom levels before the user makes a selection. This allows the processor to have multiple candidate images ready for computational combination, enabling rapid focus and zoom adjustments without time-consuming mechanical movements.
2Adaptability or versatility
If multiple optical elements are integrated for three-dimensional viewing, then the viewing capability is enhanced, but the manufacturing cost increases
Solution Approach 1:
The patent replaces complex mechanical optical elements with a digital imaging system consisting of image sensors and processors. The three-dimensional viewing effect is achieved through computational methods such as capturing images from slightly different perspectives and combining them digitally, rather than requiring multiple precision optical components.
Solution Approach 2:
The system creates digital copies of the specimen from multiple perspectives using image sensors, then processes these copies computationally to generate three-dimensional views. This digital copying approach eliminates the need for expensive optical duplication mechanisms while achieving the same viewing effect.
3Adaptability or versatility
If traditional stereoscope design is used, then the optical path is straightforward, but the ability to share and view images remotely is limited
Solution Approach 1:
The patent integrates multiple functions into a single device: digital image capture, processing, display, and wireless transmission. The same image sensor and processor used for three-dimensional viewing also enable image sharing and remote viewing capabilities, eliminating the need for separate transmission equipment.
Solution Approach 2:
The processor acts as an intermediary that converts optical images captured by sensors into digital signals that can be transmitted electronically. This digital intermediary format enables easy sharing and remote viewing without requiring complex optical coupling mechanisms between multiple devices.
