Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the parking assist device directly processes vehicle-specific data for multiple vehicle models, then the device can handle diverse vehicle types, but the device complexity increases significantly

Engineering Contradiction:

Improveability to handle various vehicle modelsVSAvoidconfiguration complexity of parking assist device

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces a relay device as an intermediary component between the parking assist device and vehicles of different models. The relay device receives vehicle-specific data from various vehicle models, performs the necessary data conversion and processing, and transmits standardized data to the parking assist device. This mediator approach allows the parking assist device to work with multiple vehicle types without directly processing vehicle-specific protocols, thereby resolving the contradiction between adaptability and device complexity.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the parking assist device includes additional processing capabilities for each vehicle type, then it can accommodate more vehicle models, but the ease of operation and configuration decreases

Engineering Contradiction:

Improvesupport for different vehicle modelsVSAvoidsimplicity of data processing

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent extracts the vehicle-specific data processing functionality from the parking assist device and places it in a separate relay device. The relay device is responsible for receiving diverse vehicle data, converting it to standardized formats, and forwarding it to the parking assist device. This extraction allows the parking assist device to maintain simple, standardized processing operations while still supporting multiple vehicle models through the relay device's conversion capabilities.

AI summary

A parking assist device performs parking assist. A vehicle receives assist from the parking assist device. A type determination unit determines a type of received data, which represents data received from the parking assist device or the vehicle. A replacement transmission unit replaces the received data with at least one transmission data, which is prepared in advance, according to the type of the received data and transmits the transmission data to the receiver device, when the type of the received data is a first type. A transfer unit transfers the received data as the transmission data to the receiver device when the type of the received data is a preset second type.
