Solution Overview

Problem

Existing data storage systems in publicly accessible areas face issues with secure removal of data memories, as mechanical locks can lead to data loss or damage and unauthorized access, and the management of key rights is cumbersome due to the need for exclusive or extensive key distribution.

Innovation Solution

A receiving device with a locking mechanism that uses an electronic key with a readable code to securely release the data memory, ensuring it can only be removed after operation is terminated and the locking mechanism is electronically unlocked, featuring a control device and an interface for key authorization, and a display for status indication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a mechanical lock is used to secure the data memory, then the data memory is protected from unauthorized removal, but the data memory can be removed by unauthorized persons if the lock is mechanically opened

Engineering Contradiction:
Improvesecurity of data memoryVSAvoidunauthorized access and data loss
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the mechanical locking system with an electronic locking mechanism that uses electronic keys with unique codes. The control device reads the code from the electronic key and determines whether to release the locking device based on authorization, thereby substituting mechanical key-operated locks with an electronic authorization system that prevents unauthorized removal while allowing controlled access.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the locking mechanism from a purely mechanical state to an electronically controlled state with multiple authorization levels. The control device evaluates the code from the electronic key and transitions the locking device between locked and unlocked states based on the authorization level, enabling differentiated access control for different user groups.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If several recording systems can be opened with one and the same key, then key distribution is simplified, but the group of authorized persons becomes extremely large

Engineering Contradiction:
Improvekey distributionVSAvoidauthorization control
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent segments the authorization system into different authorization levels (first authorization level for removal rights, second authorization level for lower privileges). Electronic keys are assigned specific authorization levels, allowing the system to distinguish between different user groups and grant appropriate permissions, thereby maintaining security while enabling broad but controlled access.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The electronic key system serves multiple functions: it provides authentication, determines authorization level, and controls the locking mechanism. A single electronic key can be used across multiple recording systems while maintaining individual authorization levels, combining universality of use with precision of control.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of operation

If the data memory is released immediately after mechanical lock opening, then the data memory can be removed easily, but the data memory may be removed while still in operation causing damage or data loss

Engineering Contradiction:
Improveremoval of data memoryVSAvoiddata integrity
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The control device performs preliminary actions before releasing the locking device: it reads the code from the electronic key, evaluates the authorization level, determines whether the data memory is in operation, and only then releases the locking device if authorized and safe to do so. This preliminary evaluation prevents premature removal that could cause data loss.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The control device continuously monitors the operational state of the data memory and uses this feedback to control the locking mechanism. The system only releases the data memory when the evaluation result indicates it is safe to do so, creating a feedback loop that ensures data integrity while enabling removal when appropriate.

Inventive Principle:
Principle #23Feedback

AI summary

The device (10) has a locking device for fixing a data storage medium to or in the retaining device. A releasing unit (15) is arranged for removing fixing effect of the locking device, so as to release the data storage medium, where the releasing unit is activated by an electronic key (30). An actuating element (11) is actuated by mechanical force acting on the data storage medium by a mold element (25). The retaining device is designed in such a manner that a communication between the data storage medium and the retaining deice is allowed only when the actuating element is actuated. Independent claims are also included for the following: (1) a data storage medium comprising a data carrier and a housing that partially surround the data carrier (2) a method for removing a data storage medium from a retaining device.
