Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If image information is transferred between display devices with different rendering capabilities, then the system achieves versatility and adaptability, but delays occur during transfer and rendering may fail

Engineering Contradiction:

Improvecompatibility between display devicesVSAvoidrendering success rate

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The system dynamically switches between two transfer modes (first transfer mode with source rendering, second transfer mode with destination rendering) based on the rendering capabilities of the source and destination devices. This dynamic adaptation ensures reliable rendering while maintaining versatility across different device combinations.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the transfer mode parameter based on the rendering capability parameters of the display devices. By detecting whether the destination device has sufficient rendering capability, the system selects the appropriate transfer mode to ensure successful rendering while adapting to different device configurations.

Inventive Principle:

Principle #35Parameter changes

2Ease of operation

If the transfer mode is fixed, then the system is simple to operate, but it cannot adapt to different rendering capabilities causing delays and failures

Engineering Contradiction:

Improvetransfer mode managementVSAvoidimage transfer efficiency

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The system automatically determines the appropriate transfer mode by comparing the rendering capabilities of the source and destination devices, eliminating the need for manual configuration. This self-service approach maintains ease of operation while optimizing image transfer efficiency for different device combinations.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system uses feedback from the rendering capability detection to automatically select the optimal transfer mode. By monitoring whether the destination device can perform rendering, the system adjusts the transfer mode to prevent delays and failures while maintaining simple operation for the user.

Inventive Principle:

Principle #23Feedback

3Reliability

If rendering is performed at the transfer source, then the transfer destination can display images, but delays occur when the destination lacks rendering capability

Engineering Contradiction:

Improvedisplay reliabilityVSAvoidtransfer delay

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system dynamically selects whether the transfer source or transfer destination performs rendering based on the destination device's capability. When the destination has rendering capability, it performs rendering locally (avoiding delays). When it lacks capability, the source performs rendering (ensuring reliability). This dynamic approach balances speed and reliability.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the rendering location parameter based on the destination device's rendering capability. By switching between source-rendering mode and destination-rendering mode, the system optimizes the balance between transfer speed and display reliability for different device configurations.

Inventive Principle:

Principle #35Parameter changes

4Adaptability or versatility

If the system supports multiple transfer modes, then it adapts to different devices, but the system complexity increases

Engineering Contradiction:

Improvedevice compatibilityVSAvoidtransfer mode determination

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system uses a straightforward parameter comparison approach, checking whether the destination device has rendering capability to determine the transfer mode. This simple parameter-based decision logic achieves high device compatibility without significantly increasing system complexity.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The system automatically determines the appropriate transfer mode by comparing device capabilities, eliminating the need for complex manual configuration or user intervention. This self-service mechanism achieves versatility while keeping the system relatively simple to operate and manage.

Inventive Principle:

Principle #25Self-service

AI summary

A vehicle display device transfers image information to a transfer destination that is a display device included in a vehicle, and includes: a transfer mode determiner that determines a transfer mode of the image information suitable for a rendering capability of the transfer destination, based on the image information, a rendering capability of a transfer source that is the vehicle display device, and the rendering capability of the transfer destination; and a transfer processor that converts a preset transfer mode to the transfer mode determined by the transfer mode determiner, and transfers the image information to the transfer destination in the transfer mode as converted.
