Fingerprint Scanner Wireless Programming via Handheld Transmitter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing access control systems for buildings face challenges in simple programming and user training, particularly with the recognition of master fingers and the differentiation between main and guest users, leading to complex reset processes and difficulties in selective user deletion.
Innovation Solution
A multi-channel hand-held transmitter device is used to program a finger scanning device wirelessly, eliminating the need for master finger identification and allowing for selective training and deletion of user types by transmitting signals through different channels, enabling easy distinction between main and guest users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a master fingerprint is used for programming and user registration, then the system can authenticate and register users, but the system becomes complex to reset and difficult to manage when the master fingerprint is no longer recognized
Solution Approach 1:
The patent extracts the programming and user management functions from the master fingerprint authentication flow. A separate programming mode is introduced that can be activated by specific fingerprint patterns (e.g., scanning the same finger multiple times in sequence), allowing user registration and management without relying on a continuously recognized master fingerprint for system control operations.
Solution Approach 2:
The patent introduces an intermediary programming mode that mediates between the fingerprint scanner and the control unit. This mode acts as a bridge, allowing user registration and management operations to be performed through a distinct activation sequence rather than through continuous master fingerprint authentication, thereby simplifying system reset procedures.
2Device complexity
If the system stores only master user fingerprint characteristics, then the system structure is simple, but it cannot differentiate between primary and secondary users for selective registration and deletion
Solution Approach 1:
The patent segments the user memory structure into multiple user records, each with its own fingerprint characteristics and access permissions. Instead of a single master user entry, the system can store multiple user profiles (primary users, secondary users, guests) that can be independently managed, registered, and deleted based on specific needs.
Solution Approach 2:
The patent implements dynamic user management where the system can adaptively assign different user types and permissions during the registration process. The control unit dynamically creates and manages user records based on the registration mode activated, allowing flexible differentiation between primary and secondary users without rigid pre-configuration.
3Adaptability or versatility
If additional programming units with displays are added to enable selective user deletion and programming, then user management functionality is improved, but device complexity and design effort increase
Solution Approach 1:
The patent makes the fingerprint scanner multi-functional by enabling it to serve both as an authentication device for access control and as a programming interface for user management. The same scanner hardware can detect fingerprint patterns to activate different modes (authentication mode vs. programming mode), eliminating the need for separate programming units with displays and reducing overall system complexity.
Solution Approach 2:
The system enables self-service user management where users can register and manage their own access permissions through the fingerprint scanner interface. The scanner itself provides the programming capability through specific activation sequences, allowing users to perform registration and management operations without requiring external programming devices or complex display interfaces.

AI summary
This is an access control device for a locking system, in particular a building locking system, comprising a fingerprint scanner with at least one scan field, a control unit, and a receiver for wirelessly receiving programming signals. The control unit's memory allows for the storage of user fingerprint characteristics of different users in multiple memory locations. Furthermore, a handheld transmitter with at least one transmitter and at least one programming button is provided. This transmitter wirelessly transmits at least one programming signal to the receiver of the fingerprint scanner to initiate a programming function. After receiving the programming signal, the user fingerprint characteristics of a user can be stored in a memory location.
