Solution Overview

Problem

Current vehicle security systems do not effectively prevent unauthorized use and theft, and lack the ability to adapt performance based on operator experience levels without compromising security.

Innovation Solution

A vehicle security system that includes a controller with a secure once mode and a secure all mode, requiring a valid security code for operation, and the ability to limit prime mover output until a valid code is entered, with temperature monitoring and multiple mode configurations based on security codes for different operational settings.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a security code is required for vehicle operation, then vehicle security is improved, but device complexity increases

Engineering Contradiction:
Improvevehicle securityVSAvoidsecurity system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces a transponder as an intermediary device that stores and transmits security codes wirelessly. This mediator enables secure authentication without requiring direct physical interaction with the vehicle's control system, thereby enhancing security while keeping the interface simple for the user.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces traditional mechanical key systems with an electronic RFID-based transponder system. This substitution eliminates physical key manipulation, reduces mechanical wear and theft vulnerability, and enables more sophisticated security protocols through wireless communication and electronic code verification.

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

2Reliability

If performance is limited during start-up until security code is provided, then security is improved, but productivity decreases

Engineering Contradiction:
ImprovesecurityVSAvoidvehicle operation readiness
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent implements preliminary security verification by requiring the transponder to be present and validated before the vehicle's power system is fully activated. The controller limits power system operation during start-up until authentication is complete, ensuring security is established before full functionality is available.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent creates a dynamic security system where the vehicle's operational state changes based on authentication status. During start-up, the system transitions from a limited state (security check required) to a full operational state (authentication successful), allowing flexible control over when performance restrictions are applied.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If multiple security codes are used for different operation modes, then adaptability is improved, but device complexity increases

Engineering Contradiction:
Improveoperation mode configurationVSAvoidsecurity code management
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent makes the single transponder device universal by enabling it to store and transmit multiple different security codes, each corresponding to different operational modes (e.g., novice, expert, cruise). This multi-functionality allows one device to serve multiple security and performance configuration purposes without requiring separate authentication devices for each mode.

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