Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a card-type vehicle key module is inserted into a mobile terminal, then vehicle control functionality is added and separate physical keys are no longer needed, but the mobile terminal structure becomes more complex

Engineering Contradiction:
Improvevehicle control functionalityVSAvoidmobile terminal structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The vehicle key module is designed as a card-type component that can be inserted into a slot within the mobile terminal, allowing the vehicle control functionality to be nested within the existing mobile terminal structure. This enables the mobile terminal to function both as a communication device and as a vehicle key without requiring separate physical keys.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The mobile terminal is designed to perform multiple functions by integrating the vehicle key module, allowing it to serve as both a communication device and a vehicle access control device. This multi-functionality eliminates the need for separate physical vehicle keys while adding convenience to the user.

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

2Area of stationary object

If the vehicle key module is directly connected to antennas without a printed circuit board, then antenna performance is optimized and PCB space is minimized, but the electrical connection reliability may be compromised

Engineering Contradiction:
ImprovePCB spaceVSAvoidelectrical connection reliability
Core Design Contradiction:
Area of stationary objectVSReliability

Solution Approach 1:

The vehicle key module is extracted from the traditional PCB-based implementation and designed as a standalone card-type component that connects directly to the antennas. This extraction eliminates the need for additional PCB space while maintaining electrical connection through direct contact points on the card module.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The card-type vehicle key module itself serves as an intermediary component that provides the electrical connection between the antenna and the vehicle control circuitry. The card module includes contact points that directly interface with the antenna, eliminating the need for a separate PCB while ensuring reliable electrical connection.

Inventive Principle:
Principle #24Intermediary (Mediator)
