Innovation Solution

A vehicle control system that configures itself for authenticated transmissions by using identifier messages, analyzing control signals, and adapting to different remote device manufacturers and formats, allowing for seamless communication through a series of training processes involving user input and adaptive signal transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a vehicle control system uses pre-configured authentication methods for remote devices, then communication security is improved, but compatibility with different remote device manufacturers and formats deteriorates

Engineering Contradiction:
Improvecommunication securityVSAvoidcompatibility with different remote devices
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system dynamically changes authentication parameters based on the detected remote device type. The control unit analyzes control signals from different manufacturers and adjusts authentication methods, codes, and communication formats to match the specific remote device, thereby maintaining security while achieving broad compatibility

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The authentication mechanism transitions from static pre-configured methods to dynamic adaptive authentication. The system continuously learns from control signals received from various remote devices and adjusts its authentication approach in real-time, enabling it to handle multiple device types without compromising security

Inventive Principle:
Principle #15Dynamics

2Measurement precision

If a vehicle control system implements complex training processes for each remote device, then authentication accuracy is improved, but configuration time and user effort increase

Engineering Contradiction:
Improveauthentication accuracyVSAvoidconfiguration time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The control system performs self-configuration by automatically analyzing control signals from remote devices and determining the appropriate authentication method. The system autonomously completes what would traditionally require manual training processes, significantly reducing configuration time while maintaining authentication accuracy

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system performs preliminary analysis of control signals to pre-determine the authentication method before actual authentication occurs. By analyzing signal characteristics in advance, the system prepares the appropriate authentication parameters, eliminating the need for time-consuming trial-and-error training processes

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If a vehicle control system supports multiple authentication formats for different manufacturers, then versatility is improved, but system complexity increases

Engineering Contradiction:
Improvesupport for multiple manufacturersVSAvoidsystem configuration complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The control unit acts as an intermediary that receives control signals from various remote device manufacturers and translates them into a unified authentication framework. This intermediary layer abstracts the complexity of multiple formats, allowing the system to support diverse devices without requiring complex configuration for each manufacturer

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The authentication system is designed with universal capabilities to handle multiple authentication formats through a single unified interface. The control unit can authenticate with different remote device types using the same basic mechanism, adapting parameters as needed, thereby reducing system complexity while maintaining versatility

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