Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a conventional door lens assembly with a wide-angle lens is used, then the device structure is simple, but the vision field is limited and recognizability is poor
Solution Approach 1:
The patent uses a digital camera to capture optical images and converts them into digital images for display. This copying process allows the system to overcome the limited vision field and poor recognizability of conventional optical lenses by creating a digital representation that can be enhanced and displayed on a screen, thereby improving measurement precision without significantly increasing device complexity.
Solution Approach 2:
The patent transitions from a purely optical viewing system to a digital imaging system. By capturing images optically and then displaying them digitally, the system adds a digital dimension that enables better recognizability and wider effective vision field while maintaining relative structural simplicity through the integration of existing door lens assembly components.
2Measurement precision
If a conventional monitoring system with camera and display is used, then recognizability is improved, but installation complexity increases and modularized structure is lacking
Solution Approach 1:
The patent divides the monitoring system into separate functional modules: the digital camera unit, the display unit, and the connection means for integration with the door lens assembly. This segmentation allows each component to be independently optimized and installed separately, greatly improving installation convenience while maintaining high recognizability through digital imaging capabilities.
Solution Approach 2:
The connection means is designed to universally interface with existing door lens assemblies, allowing the digital monitoring system to be integrated with various commercial door lens configurations. This universal interface enables easy installation and adaptability without requiring specialized installation procedures, thereby improving ease of operation while maintaining enhanced recognizability.
3Measurement precision
If additional components are added to the door lens assembly for digital integration, then digital image conversion is enabled, but fabrication cost increases
Solution Approach 1:
The patent uses a digital camera to copy optical images into digital format. This approach enables high-quality digital image conversion without requiring complex or expensive custom optical components. The digital camera serves as an efficient intermediary that captures optical information and converts it to digital signals, thereby improving digital image quality while keeping fabrication costs low by avoiding the need for new molds or complex additional optical components.
Solution Approach 2:
The digital camera acts as an intermediary between the optical door lens assembly and the digital display system. This intermediary device enables the conversion of optical images to digital images without requiring direct integration of complex optical-digital hybrid components. By using the camera as a mediator, the system achieves high digital image quality while maintaining ease of manufacture, as the camera is a standard, easily fabricated component rather than a custom optical component.
