Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If display image size is increased to improve visibility, then viewing ease is improved, but vibration-induced carsickness increases

Engineering Contradiction:

Improveviewing easeVSAvoidcarsickness

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The display image parameters (brightness, blur, area, transparency) are dynamically adjusted based on detected vibration characteristics. The presentation processing unit continuously monitors vibration and modifies display properties in real-time, transitioning from static to adaptive display behavior that responds to vehicle motion conditions.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes multiple display parameters simultaneously including brightness (lowering during vibration), blur (increasing to soften edges), area (reducing overall size), and transparency (modifying opacity). These parameter modifications transform the display output to reduce visual stress while maintaining information accessibility.

Inventive Principle:

Principle #35Parameter changes

2Illumination intensity

If display brightness is increased to improve visibility, then information readability is improved, but visual stress during vibration increases

Engineering Contradiction:

Improvedisplay brightnessVSAvoidvisual stress

Core Design Contradiction:

Illumination intensityVSObject-affected harmful factors

Solution Approach 1:

Brightness is dynamically adjusted as a key parameter in response to vibration detection. The presentation processing unit lowers brightness during vibratory events, transforming the illumination intensity to reduce visual stress while maintaining sufficient visibility for safe operation.

Inventive Principle:

Principle #35Parameter changes

3Area of moving object

If display area is increased to improve information presentation, then usability is improved, but vibration impact on user comfort decreases

Engineering Contradiction:

Improvedisplay areaVSAvoiduser discomfort

Core Design Contradiction:

Area of moving objectVSObject-affected harmful factors

Solution Approach 1:

Display area is dynamically modified based on vibration conditions. The presentation processing unit reduces display area during vibratory events, transforming from a fixed large display to an adaptive size that minimizes user discomfort while preserving essential information presentation.

Inventive Principle:

Principle #15Dynamics
