Desktop Safety Box Palm Vein Unlocking for Rapid Emergency Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing desktop safety boxes with fingerprint unlocking are not conducive to quick unlocking in emergency situations due to a small recognition area.
Innovation Solution
A desktop safety box equipped with a palm vein unlocking module and a mechanical unlocking mechanism, allowing for rapid access using palm vein recognition and a mechanical key in emergencies, along with a locking device that transitions between locked and unlocked states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If fingerprint unlocking is used, then security is maintained, but unlocking speed is slow due to small recognition area
Solution Approach 1:
The patent replaces the mechanical fingerprint recognition system with an optical palm vein recognition system. The palm vein recognition module uses optical sensors to detect vein patterns through light transmission, substituting the mechanical fingerprint scanner with an optical-based larger area recognition system that enables faster unlocking while maintaining security.
Solution Approach 2:
The patent transitions from two-dimensional fingerprint recognition to three-dimensional palm vein recognition. By utilizing the depth dimension of the palm structure and vein patterns, the system achieves a larger effective recognition area without increasing the surface footprint, thereby improving unlocking speed while maintaining compact device design.
2Reliability
If only electronic unlocking is provided, then convenience is improved, but reliability decreases in emergency situations
Solution Approach 1:
The patent implements a dynamic unlocking system that adapts to different user needs and emergency conditions. The system can switch between electronic palm vein recognition for normal use and mechanical key unlocking for emergency situations, providing flexibility and reliability. The control unit dynamically selects the appropriate unlocking method based on detected conditions or user input.
Solution Approach 2:
The patent prepares multiple unlocking methods in advance, including both electronic palm vein recognition and mechanical key unlocking options. This redundancy acts as a cushion against potential failures of the electronic system, ensuring that users can always access the safety box reliably whether through electronic or mechanical means.

AI summary
The present disclosure relates to a desktop safety box including a housing, a cover, a locking device, and a palm vein unlocking module. The housing defines an accommodating cavity and an opening communicated with each other. The cover is mounted on the housing and is capable of opening or closing the opening. When the locking device is in a closed state, a relative position between the cover and the housing is locked, and the opening is closed. When the locking device is in an unlocked state, a lock between the cover and the housing is released, and the opening is allowed to be opened. The palm vein unlocking module is mounted on the housing, electrically connected to the locking device, and configured to acquire palm vein information and drive the locking device to switch to the unlocked state.
