Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If current digital vehicle key solutions are implemented, then vehicle key functions can be integrated into mobile terminal devices, but users are required to perform a large amount of operations which leads to poor user experience

Engineering Contradiction:
Improvedigital vehicle key integrationVSAvoiduser operations
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The vehicle automatically detects mobile terminals in proximity and performs authentication without requiring users to manually operate the digital vehicle key. The system self-initiates the connection, authentication, and vehicle control processes based on detected trajectory and location information, eliminating the need for users to perform multiple manual operations.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system pre-establishes communication connections with multiple mobile terminals and continuously monitors their location and trajectory information before actual vehicle operation is needed. This preliminary detection and authentication preparation enables the vehicle to be ready for control commands without requiring users to perform setup operations at the moment of use.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If current digital vehicle key solutions are implemented, then vehicle key functions can be integrated into mobile terminal devices, but the App customized by car factory must complete too many specific operations which brings poor usage experiences to consumers

Engineering Contradiction:
Improvedigital vehicle key integrationVSAvoidApp operations
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent extracts the complex authentication and control logic from the mobile terminal App and relocates it to the vehicle's control system. The vehicle independently performs trajectory analysis, authentication decisions, and control command execution, eliminating the need for the App to complete multiple specific operations and reducing software complexity on the mobile device.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The vehicle's control system acts as an intermediary that receives raw trajectory and location data from mobile terminals, processes this information through its own authentication algorithms, and generates control commands. This intermediary processing layer eliminates the need for complex App-based operation sequences and simplifies the user interface.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Extent of automation

If senseless operation information is determined for digital vehicle keys, then the vehicle can sense the number of users and their intentions, but this requires enhanced detection and measurement capabilities

Engineering Contradiction:
Improvesenseless authenticationVSAvoidtrajectory information
Core Design Contradiction:
Extent of automationVSDifficulty of detecting and measuring

Solution Approach 1:

The vehicle's communication system performs multiple functions: it not only establishes basic communication connections with mobile terminals but also simultaneously extracts location information, trajectory data, and authentication credentials from the same communication channel. This multi-functional use of the communication system enables senseless authentication without requiring separate dedicated sensors or measurement devices.

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

Solution Approach 2:

The system continuously monitors communication signals from mobile terminals to track their trajectory and location changes over time. This feedback loop provides real-time information about user movement patterns and intentions, enabling the vehicle to automatically determine authentication status and initiate appropriate control operations based on detected behavior patterns.

Inventive Principle:
Principle #23Feedback
