Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If mobile electronic devices with built-in digital cameras are used to capture images of authentication devices, then the portability and ease of use are improved, but the image quality and fidelity are insufficient for reliable authentication
Solution Approach 1:
The patent combines multiple functions into a single portable authentication device: a digital camera for image capture, a light emitting device for supplemental illumination, and a display device for showing visual guides. This integration maintains portability while significantly improving image quality through controlled lighting conditions and high-resolution capture capabilities.
Solution Approach 2:
The light emitting device acts as an intermediary to provide controlled supplemental illumination between the camera and the authentication device being captured. This mediator ensures optimal lighting conditions for high-fidelity image capture, resolving the contradiction between portability and image quality.
2Measurement precision
If supplemental illumination is added to improve image quality, then the image fidelity and data quantity are improved, but the device complexity increases
Solution Approach 1:
The authentication apparatus merges the light emitting device, image capturing device, and display device into a single integrated unit. This combination improves image fidelity through controlled illumination while avoiding the complexity of multiple separate devices, as all components work together in a coordinated manner.
Solution Approach 2:
The portable authentication device performs multiple functions: capturing images with controlled illumination, displaying visual guides for proper positioning, and processing authentication data. This multi-functionality achieves high image fidelity without requiring complex specialized equipment for each function.
3Quantity of substance
If the image capturing device is positioned closer to capture more detail, then the data quantity is improved, but the risk of overexposure or underexposure increases
Solution Approach 1:
The display device provides visual feedback by showing the captured image in real-time or near-real-time, allowing the operator to assess exposure levels and adjust positioning or lighting conditions. This feedback mechanism ensures sufficient pixel data quantity while maintaining reliable exposure control.
Solution Approach 2:
The light emitting device provides preliminary controlled illumination before the actual image capture, ensuring that the authentication device is properly lit to prevent overexposure or underexposure. This preliminary action allows for optimal exposure conditions when capturing high-detail images at close distances.

AI summary
An apparatus comprises an image capturing device, a light emitting device for illuminating an object to be captured by the image capturing device, a visual guide to guide a user to aim the apparatus at a target authentication device, and a processor. The visual guide is devised such that when the apparatus is aimed at the target authentication device following guidance of the visual guide, the brightness levels on an image of the target authentication device captured by the image capturing device while under illumination of the light emitting device are within a predetermined range of brightness levels to facilitate verification of authenticity with reference to the captured image of the target authentication device.
