Tilting Iris Camera Assembly Without Bracket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices with iris recognition systems require a larger size and expanded black matrix (BM) regions due to the tilting structure of the iris camera, which increases the device size and compromises aesthetics and functionality.
Innovation Solution
An imaging sensor assembly with a tilting structure that eliminates the need for a bracket, allowing the iris camera to be tilted without expanding the device size, by using a through-hole in the housing to accommodate the camera barrel and lenses, and a sensor housing that surrounds the outer surface, enabling efficient iris image detection without increasing the device's dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a bracket is used to support the iris camera in a tilting structure, then the iris camera can be tilted to face the center of the user's face, but the overall size of the electronic device increases
Solution Approach 1:
The patent removes the bracket component from the traditional iris camera support structure. Instead of using a separate bracket to achieve tilting, the invention integrates the tilting function directly into the lens barrel structure, thereby eliminating the bracket and reducing the overall device volume while maintaining the iris camera's ability to tilt and face the center of the user's face
Solution Approach 2:
The patent merges the bracket function with the lens barrel structure. The lens barrel is designed to directly provide the tilting support function that was previously separated into a distinct bracket component. This integration eliminates the need for additional space-consuming brackets while preserving the essential tilting capability for accurate iris recognition
2Ease of operation
If a bracket is used to support the iris camera, then the iris camera can be mounted at an inclined angle, but the black matrix (BM) region must be expanded to accommodate the hole size
Solution Approach 1:
The patent extracts and eliminates the bracket component that previously required additional hole space in the black matrix region. By removing the bracket and integrating its support function into the lens barrel structure, the invention reduces the hole size requirements in the BM region, thereby preventing the need to expand the BM region while maintaining mounting flexibility
Solution Approach 2:
The patent combines the support function into the lens barrel structure itself, eliminating the need for separate bracket mounting holes in the black matrix region. This integration reduces the total hole size requirements in the BM region, allowing the region to maintain its original compact size without expansion
