Programmable Key Activation Without Batteries or Remote Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing activation devices for programmable keys are cumbersome and inconvenient due to power draining circuitry, making them difficult to carry and potentially vulnerable to remote hacking, while maintaining security.
Innovation Solution
A compact, portable activation device that derives power from the programmable key, lacks external communication capabilities, and uses a keypad for input, ensuring security by requiring a decipher input for unlocking access rights, with a programmable-key retaining element for secure key retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If power draining circuitry and external communication capabilities are included in the activation device, then the device can provide additional security and activate programmable keys, but the device becomes cumbersome, difficult to carry, and vulnerable to remote hacking
Solution Approach 1:
The patent removes power draining circuitry and external communication capabilities from the activation device, extracting only the essential activation function. The device now consists of a simple receiving portion and cipher-key input arrangement without batteries, wireless modules, or network interfaces, making it pocketable while maintaining security through physical presence requirement and decipher code verification
Solution Approach 2:
The patent introduces a decipher code as an intermediary security layer between the user and the programmable key activation. The cipher-key input arrangement requires the user to enter a decipher code, which acts as a mediator that prevents unauthorized activation while keeping the device itself simple and portable without needing complex communication hardware
2Adaptability or versatility
If power draining circuitry is included in the activation device, then the device can operate independently, but the device becomes inconvenient to carry and may experience power drainage issues
Solution Approach 1:
The patent extracts the power source (battery) and power management circuitry from the activation device, leaving only the passive receiving portion and input arrangement. The device operates independently of power sources by requiring only the physical presence of the programmable key and user input of the decipher code, making it extremely portable and eliminating power drainage concerns
Solution Approach 2:
The activation device is designed to be serviced by the programmable key itself, which provides power and communication capabilities when inserted. The key's circuitry powers the activation device temporarily during the activation process, eliminating the need for separate power sources while maintaining the ability to perform the activation function

AI summary
An activation device for activating a programmable key is provided. The activation device comprises a programmable-key receiving portion, a cipher- key input arrangement, and circuitry configured to receive a first signal from the programmable key and, subsequently, return a second signal to the programmable key for unlocking a stored access right of the programmable key. The activation device is exclusively connectable to a programmable key configured to be activated by the activation device.
