Camera Assembly Deflection Member for Iris Unlocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Infrared light emitted from an infrared lamp in electronic devices, such as mobile phones, often deviates from the user's eyes due to distance, resulting in insufficient infrared light capture by the camera, leading to iris unlocking failures during iris identification processes.
Innovation Solution
A camera assembly that includes a deflection member positioned between the infrared lamp and the camera, which deflects the infrared light towards the camera's central axis, ensuring optimal light capture and improving the iris unlocking process without the need for specialized or costly infrared lamps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the infrared lamp is positioned at a certain distance from the camera, then the device structure is simplified, but the infrared light deviates from the user's eyes resulting in insufficient light capture
Solution Approach 1:
The patent introduces a reflective member (mirror or prism) as an intermediary component between the infrared lamp and the camera. This reflective member redirects the infrared light path, allowing the lamp to be positioned at a distance from the camera while still directing sufficient infrared light toward the user's eyes. The reflective member acts as a mediator that resolves the conflict between structural simplicity and light capture effectiveness.
2Manufacturing precision
If a specialized infrared lamp with precise beam control is used, then the infrared light can be accurately directed, but the manufacturing cost increases
Solution Approach 1:
The patent replaces the need for a mechanically complex specialized infrared lamp with a simple reflective member (such as a standard mirror or prism). Instead of requiring the infrared lamp itself to have precise beam control capabilities, the system uses the reflective member to redirect the light. This substitution dramatically reduces manufacturing costs while achieving the same effect of accurately directing infrared light toward the user's eyes.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The deflection member effectively directs infrared light to the camera, enhancing the capture of infrared light and preventing unlocking failures, while allowing for adjustable deflection angles and reducing manufacturing costs by using standard infrared lamps.
Implementation Method 1
a deflection member arranged on a side of the cover plate facing towards the main board and being opposite to the camera. The deflection member is configured to deflect infrared light emitted from the infrared lamp towards a direction of a central axis of the camera.
