Electronic Lock Cylinders With Dual Interface Master Key
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic locking systems are cumbersome and time-consuming to program, especially as the number of locking cylinders and transponders increases, and they become complex when the power supply fails.
Innovation Solution
The locking mechanisms have two inputs: one for communication with passive transponders and another for data and energy exchange with an active master key, which includes a data memory for the locking plan and a power supply, allowing for convenient programming and operation even without a power source.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple locking cylinders and transponders are added to the locking system, then the system's functionality and coverage are improved, but the programming time and complexity increase significantly
Solution Approach 1:
The master key performs preliminary actions by automatically reading all locking cylinders in the system, storing their identification numbers in its memory, and pre-calculating authorization relationships. This preliminary data collection and processing eliminates the need for time-consuming individual programming of each cylinder-transponder combination when the system is initially set up or modified.
2Reliability
If the power supply to the lock cylinder fails, then the reliability of the locking mechanism is compromised, but adding backup power sources increases system complexity
Solution Approach 1:
The master key acts as an intermediary energy carrier between the power source and the locking mechanism. Instead of adding backup power sources to each lock cylinder, the master key itself carries energy to temporarily power the locking mechanism during power failures, simplifying the overall system while maintaining reliability.
3Ease of operation
If individual programming of each locking cylinder is performed, then precise control over each cylinder is achieved, but the logistical effort and time required increase
Solution Approach 1:
The master key is designed as a universal programming device that can program and control multiple locking cylinders simultaneously. It reads all cylinder identification numbers, stores them in its memory, and can authorize or block transponders for any of the stored cylinders without requiring separate programming operations for each cylinder, thus achieving precise control with minimal effort and time.

AI summary
In an electronic locking system with multiple locking cylinders (2), multiple user keys (3), and a master key (1), the locking cylinders (2) have multiple inputs (8, 11) for exchanging data and electrical energy with the master key (1) and the user keys (3). The user keys (3) have passive transponders (6), while the master key (1) is actively designed for communication with the locking cylinders. A locking plan with the access rights of the user keys (3) is stored on the master key (1).
