Dual Identification Door Access Control with Mobile Key
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door access control methods lack flexibility, as they typically use only one type of identification (biological or non-biological) and do not provide an instant alternative when the identification system malfunctions or is out of order, making it difficult to manage access, especially in environments where multiple people or unspecified individuals need to enter and exit.
Innovation Solution
A door access control method that combines both biological and non-biological identification types, using a smart mobile or wear device to pick up and encode biological features, forming a mobile key that can be used to unlock doors when both types of identification are correctly provided, ensuring secure and flexible access control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If only one type of identification (biological or non-biological) is used, then the system is simple, but the system lacks flexibility and has no backup when malfunctioning
Solution Approach 1:
The identification system is segmented into two independent identification types (biological and non-biological), each capable of operating separately. The biological identification module and non-biological identification module are divided as independent functional segments, allowing the system to select and use either type based on operational needs or malfunction conditions.
Solution Approach 2:
The door access control system is designed with multi-functionality by incorporating both biological identification capabilities and non-biological identification capabilities within a single system. This universal design allows the system to perform access control through multiple identification methods, providing flexibility and backup options when one method fails.
2Reliability
If only non-biological identification is used, then the system is simple to operate, but it is difficult to monitor and identify people passing through
Solution Approach 1:
The system merges biological identification functionality with non-biological identification functionality into a unified door access control system. The biological feature pickup device captures biological data (such as facial features or fingerprints) while the non-biological identification handles access authorization, combining both functions to achieve reliable monitoring while maintaining operational simplicity.
Solution Approach 2:
The system introduces an intermediary monitoring mechanism that uses biological identification to capture and record information about individuals passing through the door. This intermediary biological data collection serves as a mediator between the simple non-biological access control and the need for reliable personnel monitoring, enabling identification without complicating the access operation.
3Reliability
If biological identification is activated, then security is improved, but the system requires more resources and time for feature pickup and verification
Solution Approach 1:
The system dynamically adjusts the identification process by first attempting rapid non-biological identification for immediate access decisions. Only when non-biological identification is insufficient or requires verification does the system activate the more time-consuming biological feature pickup and analysis processes, optimizing the balance between security and access time.
Solution Approach 2:
The system performs preliminary non-biological identification checks before initiating biological feature pickup. This preliminary action filters out clearly unauthorized access attempts early in the process, avoiding the need to perform time-consuming biological feature analysis for every access attempt, thus reducing overall access time while maintaining security.

AI summary
Door access control methods with two types of identifications use at least one of a biological unlocking identification and a non-biological unlocking identification. The first type of identification and the second type of identification can be used independently or jointly to control the locking state of a door access device correlated to a door access system.
