Control Switch Connection Apparatus for iFOB Signal Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fob key systems for vehicles allow continuous broadcasting of Electronic Radio Frequency Transmitted Signals (ERFTS), making them vulnerable to malicious interception and theft, as they remain on and transmit signals continuously without security protection, enabling criminals to replicate and use counterfeit signals to access vehicles undetected.
Innovation Solution
The Control Switch Connection Apparatus (CSCA) integrates a specifically designed circuitry into fob keys, ensuring the ERFTS is only activated when a function button is pressed and turned off when not in use, preventing continuous transmission and thus minimizing the risk of signal interception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the ERFTS is continuously broadcasted without signal protection, then the fob key system maintains simple operation and continuous availability, but the system becomes vulnerable to malicious interception and signal theft
Solution Approach 1:
The patent applies preliminary action by pre-configuring the control switch connection apparatus to automatically control the ERFTS activation state. The switches are predetermined to be connected only when specific buttons are pressed, establishing security controls in advance rather than reacting to threats. This ensures the ERFTS is protected before malicious interception can occur.
Solution Approach 2:
The control switch connection apparatus serves as an intermediary between the button presses and the ERFTS transmission. It mediates the connection by requiring specific switch activations (through button presses) to enable the ERFTS, thereby introducing a controlled intermediate layer that prevents direct, uncontrolled signal broadcast while maintaining system functionality.
2Reliability
If the ERFTS is continuously transmitted, then the fob key system remains always available for operation, but the risk of signal capture and theft increases
Solution Approach 1:
The patent implements periodic action by activating the ERFTS only during specific periods when buttons are pressed or held, rather than maintaining continuous transmission. The control switches enable ERFTS transmission temporarily during button press events, creating periodic activation cycles that maintain security while preserving operational availability when needed.
Solution Approach 2:
The system transitions from a static, continuously transmitted ERFTS to a dynamic state where transmission is activated only when required. The control switch connection apparatus dynamically connects or disconnects the ERFTS based on real-time button press events, making the system adaptive and responsive to user actions while maintaining security.
3Object-affected harmful factors
If the ERFTS transmission is activated only when buttons are pressed, then security against malicious attacks is improved, but the system requires more complex control mechanisms
Solution Approach 1:
The patent applies segmentation by dividing the control function into multiple independent switches, each associated with specific buttons. Rather than using a single complex control mechanism, the system segments the control into discrete switch units (first switch, second switch, third switch) that can be independently activated, simplifying the overall design while achieving secure controlled transmission.
Solution Approach 2:
The control switch connection apparatus implements local quality by assigning specific functions to specific switches based on their connection configurations. Each switch has a predetermined local role (e.g., first switch connected to second and third switches, second switch connected to fourth switch) that creates a distributed, modular control structure reducing overall system complexity.

AI summary
The present invention relates to a method that allows a CSCA to enable an iFOB key system once it is turned on by pressing a function button. When the function button is released, the iFOB key system is turned off. The iFOB key system includes the ERFTS, so when the iFOB key system is turned on/off, the ERFTS is also turned on/off. The embodiment of the CSCA has a double-action switch, a triple-action switch, a timer, a timer circuit and all of the circuitries that are associated with an iFOB key. The CSCA controls the length of time that current is allowed to flow from a battery source to an iFOB key system; it is this type of control that prevents an ERFTS and a customer's property from being compromised. The iFOB key system is always in the off position until it is turned on.
