Lockable Receptacle With Nested Doors And Biometric Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lockable receptacles often rely on single locking mechanisms, lacking multiple security features and real-time communication capabilities to securely store and monitor contents.
Innovation Solution
A lockable receptacle with multiple security layers, including a housing with multiple doors, a monitoring system, biometric scanners, a keypad, and wireless communication with mobile devices for authorization and activity logging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple locking mechanisms and security features are added to the receptacle, then security level is improved, but device complexity increases
Solution Approach 1:
The locking system is divided into multiple independent locking mechanisms (first locking mechanism, second locking mechanism, third locking mechanism) corresponding to different door levels. Each mechanism can be controlled separately through different authentication methods (biometric, RFID, keypad), allowing the system to achieve high security while maintaining manageable complexity through modular design
Solution Approach 2:
The receptacle structure implements nested doors where the first door, second door, and third door are arranged concentrically. The locking mechanisms are nested within each other, with the third locking mechanism positioned inside the second, which is inside the first. This nested arrangement allows multiple security layers to be integrated within a compact structure, improving security without proportionally increasing external complexity
2Reliability
If biometric scanners and wireless communication components are integrated, then authentication capability is improved, but manufacturing complexity increases
Solution Approach 1:
The control unit serves multiple functions: it processes biometric authentication data from scanners, manages RFID communication, handles keypad input, controls all locking mechanisms, and manages the mobile device interface. This multi-functional design reduces the number of separate components needed, simplifying manufacturing while maintaining comprehensive authentication capability
Solution Approach 2:
A mobile device acts as an intermediary between the user and the receptacle system. The mobile device communicates with the receptacle through wireless communication, storing authentication data and facilitating the unlocking process. This intermediary approach simplifies the receptacle's manufacturing by offloading complex data storage and processing functions to the mobile device
3Reliability
If multiple doors and locking mechanisms are implemented, then unauthorized access prevention is improved, but ease of operation decreases
Solution Approach 1:
The system dynamically adapts the unlocking process based on the user's authentication method. When biometric or RFID authentication is used, the corresponding locking mechanism unlocks automatically without requiring manual intervention for each door. The system can selectively unlock different door levels based on the authentication level, making operation simpler while maintaining security
Solution Approach 2:
The system provides feedback to the user through the mobile device, displaying the status of each locking mechanism and door. The control unit tracks which locking mechanisms are locked and which are unlocked, providing real-time feedback that helps users understand the current state of the system and simplifies the operation by reducing uncertainty

AI summary
A lockable receptacle, including a housing having five walls and an opening, a first door disposed on the housing to close the opening of the housing, a locking mechanism to lock the first door, and a camera connected to the locking mechanism to unlock the locking mechanism in response to an authorized user being recognized by the camera.
