Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the number of vehicle functions is increased to provide more convenience, then the functionality and versatility of the vehicle is improved, but the manipulation load on the driver increases and safety decreases

Engineering Contradiction:

Improvevehicle function diversityVSAvoiddriver manipulation load

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent combines multiple control functions into a single integrated touch input device with a concave region. The touch input device integrates object selection, direction control, and gesture recognition capabilities, allowing drivers to control diverse vehicle functions through one unified interface rather than multiple separate controls, thereby reducing manipulation load while maintaining functionality

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The touch input device is designed as a universal control interface that can handle multiple types of inputs (touch position, pressure, gestures) and control various vehicle functions (navigation, audio, climate control, etc.). This multi-functional design allows a single device to replace multiple specialized controls, improving ease of operation without sacrificing versatility

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If the number of vehicle functions is increased, then the versatility is improved, but the difficulty in operation increases especially for inexperienced drivers

Engineering Contradiction:

Improvenumber of vehicle functionsVSAvoidoperation difficulty

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The concave region is divided into multiple subregions with different tactile characteristics and pressure sensitivity levels. Each subregion corresponds to specific UI objects or control functions, providing localized quality variations that guide users intuitively. This spatial differentiation makes it easier for inexperienced drivers to understand and operate different functions without complex instructions

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The touch input device's concave region is segmented into multiple subregions, each associated with specific UI objects or control functions. This segmentation creates distinct tactile zones that are easier to identify and operate, reducing the cognitive load on drivers and making the system more accessible to inexperienced users while maintaining comprehensive functionality

Inventive Principle:

Principle #1Segmentation

3Measurement precision

If a touch input device with concave region is used to improve touch accuracy, then the precision of input detection is improved, but the device complexity increases

Engineering Contradiction:

Improvetouch detection accuracyVSAvoidtouch input device structure

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent employs a concave (curved) region instead of a flat touch surface. This curvature provides tactile feedback and spatial reference that enhances touch detection accuracy without requiring complex additional sensors. The geometric shape itself contributes to precision by creating natural tactile landmarks and improving finger positioning, thereby achieving high measurement precision with relatively simple structural implementation

Inventive Principle:

Principle #14Spheroidality (Curvature)
