Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple cameras (local and wireless) are integrated into the vehicle imaging system, then the coverage and monitoring capability are improved, but the system complexity and processing burden increase

Engineering Contradiction:

Improvemonitoring capabilityVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The display controller serves as an intermediary device that receives image data from multiple cameras via different interfaces (conductive and wireless), processes the data centrally, and manages the complexity of integrating multiple camera sources. This mediator approach allows the system to handle diverse camera inputs without increasing overall system complexity at the camera level.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Manufacturing precision

If unprocessed image data from local camera is received and processed, then the image quality and detail are improved, but the processing time and computational load increase

Engineering Contradiction:

Improveimage qualityVSAvoidprocessing time

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

The display controller performs preliminary processing actions on unprocessed image data by generating processed image data from the raw input. This preliminary action prepares the data in advance for display, ensuring high image quality while managing processing time through efficient central processing rather than post-capture processing.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system rushes through the processing of unprocessed image data by having the display controller generate processed image data in real-time as data is received from cameras. This allows the system to maintain high image quality while minimizing processing delays through streamlined processing operations.

Inventive Principle:

Principle #21Skipping (Rushing through)

3Speed

If processed image data from wireless camera is directly output, then the system response speed is improved, but the adaptability to different display configurations is reduced

Engineering Contradiction:

Improvesystem response speedVSAvoiddisplay configuration flexibility

Core Design Contradiction:

SpeedVSAdaptability or versatility

Solution Approach 1:

The display controller provides universal processing capability that handles both processed and unprocessed image data from different camera sources. It can selectively output appropriately processed image data to match various display configurations and requirements, making the system adaptable to different display scenarios while maintaining efficient processing.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The display controller dynamically adjusts its processing and output based on the specific display configuration and requirements. It can selectively output processed image data with varying levels of processing applied, allowing the system to optimize between speed and adaptability depending on the current operational context.

Inventive Principle:

Principle #15Dynamics

4Adaptability or versatility

If both conductive and wireless interfaces are used for camera connections, then the system versatility and installation flexibility are improved, but the interface complexity and compatibility requirements increase

Engineering Contradiction:

Improveinstallation flexibilityVSAvoidinterface complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The display controller acts as a central intermediary that manages multiple interface types (conductive and wireless). It receives data from cameras through different interfaces and统一 processes all inputs through a single processing architecture, thereby supporting installation flexibility while managing interface complexity centrally rather than distributing it across multiple components.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A display system for a vehicle includes a first camera in connection with the vehicle. The first camera outputs unprocessed image data. A second camera outputs a first processed image data. A display controller is in communication with the first camera via a conductive interface and the second camera via a wireless interface. The controller is configured to receive the unprocessed image data from the first camera and receive the first processed image data from the second camera. The controller further generates second processed image data from the unprocessed image data and selectively outputs the first processed image data and the second processed image data to a vehicle display device.
