Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If passive keyless entry systems are used, then convenience of entering the vehicle is improved, but security against unauthorized access deteriorates

Engineering Contradiction:

Improveconvenience of entering the vehicleVSAvoidsecurity against unauthorized access

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent combines multiple authentication methods (speech recognition, biometric data, RFID signals) into a single integrated authentication system. The speech codec module processes voice commands while the controller cross-validates with stored biometric templates and RFID signals, creating a multi-layered security approach that maintains convenience while significantly enhancing security against unauthorized access.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent introduces a speech codec module and biometric authentication system as intermediary layers between the user and the vehicle access system. These intermediaries process and verify authentication data before granting access, adding security verification steps without requiring the user to manually interact with the system, thus maintaining convenience while preventing unauthorized access.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If speech recognition authentication is implemented, then security against unauthorized access is improved, but device complexity increases

Engineering Contradiction:

Improvesecurity against unauthorized accessVSAvoidsystem structure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The controller is designed as a multi-functional unit that handles speech authentication, biometric verification, RFID signal processing, and vehicle control functions. The speech codec module serves multiple purposes including voice command recognition, authentication verification, and potential communication functions. This multi-functionality approach adds security capabilities while minimizing the need for separate dedicated components, thus managing system complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of operation

If wireless charging is implemented, then user convenience is improved, but energy consumption of the electronic key increases

Engineering Contradiction:

Improveuser convenienceVSAvoidenergy consumption of the electronic key

Core Design Contradiction:

Ease of operationVSUse of energy by moving object

Solution Approach 1:

The wireless charging system operates on a periodic basis rather than continuously. The electronic key enters low-power states when not near a charging source and activates wireless charging reception only when detected by a vehicle's charging field. This periodic operation mode provides convenient wireless charging capability while minimizing overall energy consumption of the electronic key battery.

Inventive Principle:

Principle #19Periodic action
