Palm Vein Safety Box Unlocking With Approach Wake-Up Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing safety boxes require users to reach inside and operate a setting key located within the box to input personal information for unlocking, which is inconvenient.
Innovation Solution
A safety box design featuring a palm vein unlocking module mounted on the housing or cover, an awakening module to detect user approach, and a locking device that switches to an unlocked state upon successful palm vein recognition, with the setting key located externally for easy operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the setting key is located inside the safety box, then the security is improved, but the ease of operation deteriorates as users must open the cover and reach inside to operate it
Solution Approach 1:
The setting key is extracted from the interior of the safety box and relocated to the exterior surface. This allows users to operate the setting key from the outside without needing to open the cover, resolving the contradiction between security (key remaining inside) and ease of operation (key accessible from outside).
Solution Approach 2:
The palm vein unlocking module serves as an intermediary between the user and the locking device. It captures palm vein information and transmits it to control the locking device, eliminating the need for physical contact with a setting key inside the box while maintaining security.
2Speed
If the palm vein unlocking module is always active, then the unlocking speed is improved, but the energy consumption increases
Solution Approach 1:
The palm vein unlocking module operates periodically rather than continuously. It activates when the awakening module detects an object approaching and deactivates when no object is detected, achieving fast unlocking when needed while reducing overall energy consumption.
Solution Approach 2:
The awakening module performs preliminary detection to sense whether an object is approaching before fully activating the palm vein unlocking module. This preliminary action allows the system to prepare for quick unlocking when needed while avoiding unnecessary energy consumption when no user is present.
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
Facilitates convenient and secure unlocking by allowing external operation of the setting key and rapid palm vein recognition, enhancing user experience and security.
Implementation Method 1
The awakening module is connected to the palm vein unlocking module and configured to detect whether an object approaches the palm vein unlocking module
Implementation Method 2
The palm vein unlocking module is mounted on the housing or the cover, and configured to acquire palm vein information
Data Source
AI summary
A safety box includes: a locking device; a palm vein unlocking module; and an awakening module. The locking device has a closed state and an unlocked state. The palm vein unlocking module is mounted on a housing or a cover and is configured to acquire palm vein information and drive the locking device to switch to the unlocked state. The awakening module is connected to the palm vein unlocking module and configured to detect whether an object approaches the palm vein unlocking module. When the awakening module does not detect any object approaching the palm vein unlocking module, at least a part of the palm vein unlocking module is in an unactuated state. When the awakening module detects that the object is approaching the palm vein unlocking module, the awakening module awakens the entire palm vein unlocking module to cause the palm vein unlocking module to start operating.
