Key and security device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Retailers face challenges in securing small, expensive items from theft as existing security devices can be easily detached or removed, and current locking mechanisms are either mechanical or electronic, lacking versatility and effectiveness.
Innovation Solution
A key with an electronic component that communicates with security devices to receive and store codes for arming and disarming, allowing for multi-purpose use across different lock types and featuring a time-out function to prevent misuse after a predetermined period.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mechanical lock is used to secure the security device to the display support, then the security device can be secured, but the key can be easily copied and stolen keys remain functional indefinitely
Solution Approach 1:
The patent replaces mechanical locking systems with electronic communication systems. The key uses an electronic component with a microprocessor that communicates with the security device through coded signals, eliminating mechanical keys and locks. This substitution prevents key copying while maintaining security functionality.
Solution Approach 2:
The patent implements a time-based parameter change where the electronic key contains a microprocessor that automatically disables the key after a predetermined time period. This temporal parameter change renders stolen or copied keys useless after expiration, dynamically altering the key's functional state over time.
2Reliability
If separate keys are used for different lock types, then each lock can be secured, but multiple keys increase complexity and reduce ease of operation
Solution Approach 1:
The patent creates a universal key design where a single electronic key with a microprocessor can communicate with and control multiple different security devices. The key contains programmable code that can interface with various lock types, eliminating the need for multiple specialized keys and simplifying key management while maintaining security.
3Ease of operation
If electronic keys without time limits are used, then convenience is improved, but stolen keys remain functional and security is compromised
Solution Approach 1:
The patent implements preliminary action by programming the electronic key with a predetermined time limit before the key is even used or stolen. The microprocessor automatically disables the key after the expiration period, proactively preventing future misuse of stolen keys without requiring any additional action from the user or security system.
Solution Approach 2:
The patent implements a feedback mechanism where the electronic key continuously monitors its own operational status and automatically disables itself when the predetermined time period expires. This self-regulating feedback loop ensures that even if a key is stolen, it becomes non-functional after the time limit, providing automatic security enforcement.

AI summary
A key for a security device is provided. The key may include an electronic component configured to communicate with one or more security devices to initially receive one or more codes associated with each of the security devices. The key may also include a memory configured to store the one or more codes associated with the one or more security devices. The electronic component is configured to communicate with each of the one or more security devices for arming and/or disarming the security devices upon a matching of the code stored by the memory with the code associated with the security device.
