Biometric Sensor Integrated Control Button for Narrow Bezel Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic apparatuses with fingerprint sensors on narrow bezels face challenges in fingerprint recognition due to small sensing areas, leading to low recognition rates and poor user experience.
Innovation Solution
A control method and electronic apparatus design that includes a biometric recognition sensor on a control button, where the sensor collects biometric images and determines if they meet a set condition, allowing the button to be moved to a new position only if the image meets the criteria, thereby improving recognition rates and user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If the fingerprint sensor is arranged at a side of the bezel to achieve narrow bezel design, then the device achieves narrow bezel design, but the sensing area becomes small making it difficult for users to locate during fingerprint recognition
Solution Approach 1:
The patent combines the control button function with the fingerprint sensor by integrating the sensing area directly into the control button. This merging allows the button to serve dual purposes: as a mechanical control element and as a biometric authentication interface, thereby increasing the effective sensing area while maintaining the narrow bezel design.
Solution Approach 2:
The control button is designed to perform multiple functions: it serves as both a mechanical control button for general operations and as a fingerprint sensor for biometric authentication. This multi-functionality increases the sensing area availability without requiring additional dedicated space on the bezel.
2Length of stationary object
If the fingerprint sensor is arranged at a side of the bezel with small sensing area, then the narrow bezel design is achieved, but the fingerprint recognition rate becomes low
Solution Approach 1:
By merging the fingerprint sensor with the control button, the patent creates a larger effective sensing area that improves fingerprint recognition reliability. The control button's larger surface area compared to a traditional bezel-mounted sensor provides better fingerprint capture while maintaining the narrow bezel aesthetic.
Solution Approach 2:
The system implements feedback mechanisms where the control button provides tactile response to user presses, and the integrated sensor provides biometric verification feedback. This feedback loop ensures reliable recognition by confirming successful fingerprint detection before proceeding with authorized operations.
3Ease of operation
If the control button is moved to a second position without biometric verification, then the operation is simplified, but security and unauthorized access control are compromised
Solution Approach 1:
The system performs preliminary biometric verification through the control button's integrated sensor before allowing the button to be moved to the second position. This preliminary action ensures that only authenticated users can access certain functions, maintaining security while keeping the operation simple for authorized users.
Solution Approach 2:
The control button acts as an intermediary between the user and the system's secure functions. It mediates the authentication process by combining mechanical pressing with biometric verification, providing a seamless security check that does not complicate the user experience for authorized operations.

AI summary
A control method includes collecting a biometric image through a sensing area of a biometric recognition sensor provided at a control button of an electronic apparatus, in response to a press operation of a user on the control button; determining whether the biometric image meets a condition; in response to determining that the biometric image meets the condition, allowing the control button to be moved from a first position to a second position; and in response to determining that the biometric image does not meet the condition, prohibiting the control button from being moved from the first position to the second position.
