Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information handling systems lack effective mechanisms to prevent unauthorized entry of removable media into computer systems, necessitating a secure and adaptable solution to accommodate various configurations.
Innovation Solution
A lockout device with a key attached to removable media and a lock attached to the receptor, featuring multiple tooth positions and groove lengths to ensure secure alignment and prevent unauthorized access, allowing for multiple key and lock configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple lock mechanism is used, then the device complexity is reduced, but the security and authorization capability deteriorates
Solution Approach 1:
The lock mechanism is segmented into multiple independent tooth positions (first, second, and third tooth positions) that can be independently configured. Each tooth position can have different tooth configurations, allowing the system to achieve high security through modular segmentation rather than a single complex locking mechanism.
Solution Approach 2:
The patent applies parameter changes by varying the tooth configurations at different positions and adjusting the groove lengths in the key. By changing these physical parameters (tooth presence/absence positions, groove lengths), the system creates multiple unique key-lock combinations without increasing overall mechanism complexity.
2Adaptability or versatility
If multiple key and lock configurations are implemented, then the adaptability and security are improved, but the device complexity increases
Solution Approach 1:
The lock mechanism is designed with multi-functionality, where the same basic lock structure can accommodate multiple key configurations through the tooth position system. The lock can work with different key types by simply changing which tooth positions have teeth, eliminating the need for completely different lock mechanisms for each key type.
Solution Approach 2:
The system allows dynamic reconfiguration of the lock mechanism by adjusting which tooth positions are active. The groove lengths in the key can be varied to match different lock configurations, creating a dynamic system that can adapt to different security requirements without physical reassembly.
3Reliability
If the lock prevents entry based on tooth position alignment, then the security is improved, but the ease of operation deteriorates
Solution Approach 1:
The lock mechanism provides self-service authentication where the key and lock automatically verify authorization through tooth position alignment. The user simply inserts the key, and the mechanical interaction of teeth with the lock mechanism automatically determines whether access is granted, eliminating the need for manual verification or complex user input.
Solution Approach 2:
The patent replaces electronic authentication systems with a purely mechanical tooth-position-based verification system. This mechanical substitution simplifies the user interface while maintaining security, as the physical alignment of teeth provides automatic authorization without requiring users to remember codes or handle electronic components.

AI summary
A device for preventing unauthorized entry of a removable media into a receptor. A key is attached to the removable media and a lock is attached to the receptor. If the key does not fit the lock, the lock prevents the removable media from fully entering the receptor. If the key does fit the lock, the lock will permit the removable media to fully enter the receptor.
