Rotatable Biometric Sensor Housing for Terminal Orientation Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing biometric data detection devices face challenges in accommodating varying orientations of data processing terminals, requiring users to adjust the position of their biological bodies to match the device's windowed face, which can be cumbersome and inconvenient, especially when the terminal is rotated.
Innovation Solution
A biometric data detection device with a rotatable housing and attachment member that allows the biometric authentication sensor to maintain a secure attachment to the terminal while adjusting the orientation of its windowed face to align with the user's biological data, enabling flexible and convenient authentication without needing to change the user's position or orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the card insert slot is provided on different side faces (left or right) of the computer, then the device can be adapted to different terminal orientations, but the fingerprint verification section requires removal and reattachment in different directions
Solution Approach 1:
The fingerprint verification section is made rotatable rather than fixed, allowing it to dynamically adjust its orientation. The rotating mechanism enables the section to pivot between different angles (e.g., 0 degrees and 180 degrees) to match the card insert slot orientation, eliminating the need for removal and reattachment while maintaining adaptability to different terminal configurations
Solution Approach 2:
The fingerprint verification section is designed with universal adaptability through its rotatable mechanism, allowing it to function correctly regardless of whether the card insert slot is on the left or right side of the terminal. This single design serves multiple orientation requirements that would otherwise require different configurations
2Device complexity
If the windowed face orientation is fixed relative to the terminal, then the attachment structure is simplified, but users must adjust their biological body position to match the device orientation
Solution Approach 1:
The windowed face is made rotatable relative to the terminal body, allowing it to dynamically change its orientation independent of the terminal's fixed structure. This enables the windowed face to align with the user's natural positioning while the terminal remains stationary, improving ease of operation without significantly increasing overall device complexity
Solution Approach 2:
The device is segmented into rotatable and fixed components, where the fingerprint verification section with the windowed face can rotate independently from the terminal body. This segmentation allows the windowed face to be oriented optimally for user interaction while the attachment structure remains relatively simple
3Adaptability or versatility
If the fingerprint verification section is removable and invertible, then it can accommodate different card insert slot positions, but the attachment process becomes more complex
Solution Approach 1:
Instead of requiring complete removal and reattachment for inversion, the fingerprint verification section incorporates a rotating mechanism that allows it to pivot 180 degrees while remaining attached to the terminal. This dynamic adjustment simplifies the attachment mechanism by eliminating the need for complete detachment while achieving the same adaptability

AI summary
A biometric data detection device includes a biometric authentication sensor electrically connected to a data processing terminal through a connecting member, a housing that houses the biometric authentication sensor, a window portion that acquires biometric data to be authenticated by the biometric authentication sensor and that is formed in the housing, and an attachment member that is rotatably provided at the housing and that renders the housing rotatable in a state in which the housing is attached to the data processing terminal.
