Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The limited space on a steering wheel makes it difficult to accommodate all necessary function buttons, and the fixed layout cannot be easily adjusted to accommodate varying functions and user preferences across different vehicle models and environments.
Innovation Solution
A method and apparatus for dynamically displaying a vehicle operation interface based on environmental and vehicle status information, user identity, and settings, allowing for adaptive switching and customization of the interface to match specific scenarios, thereby optimizing button placement and user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If more function buttons are added to the steering wheel to accommodate diverse control requirements, then the functionality and versatility of the steering wheel is improved, but the device complexity and space requirements increase, making it difficult to accommodate all functions within the limited steering wheel space
Solution Approach 1:
The patent uses virtual buttons displayed on a screen to replicate the functionality of physical buttons. These virtual buttons can be customized and adjusted without adding physical components to the steering wheel, thereby providing diverse control options while maintaining a simple physical structure.
Solution Approach 2:
The patent transitions from a two-dimensional physical layout of buttons on the steering wheel to a multi-dimensional virtual interface displayed on a screen. This allows for much greater flexibility in arranging and customizing control options without being constrained by the physical space of the steering wheel.
2Ease of operation
If physical buttons are disposed on the steering wheel rim and spoke to provide multiple functions, then the ease of operation is improved, but the area and space requirements increase, making it difficult to accommodate all necessary function buttons within the limited steering wheel space
Solution Approach 1:
The patent replaces physical buttons with virtual buttons displayed on a screen, allowing for numerous control options to be presented without occupying additional physical space on the steering wheel. The virtual interface can be customized to provide easy access to frequently used functions.
Solution Approach 2:
The patent implements a dynamic virtual interface that can be adjusted and customized based on user preferences and driving scenarios. The virtual buttons can be repositioned, resized, and reconfigured without any physical modifications to the steering wheel structure.
3Ease of manufacture
If the layout of function buttons is fixed to simplify manufacturing, then the ease of manufacture is improved, but the adaptability and versatility decrease, making it difficult to flexibly adjust types, quantities, and location layouts of function buttons for different vehicle models and user preferences
Solution Approach 1:
The patent uses a virtual interface that can be software-configured to provide different button layouts and functions without requiring physical reconfiguration or customization of the steering wheel hardware. This allows for easy adaptation to different vehicle models and user preferences while maintaining a standardized physical steering wheel design.
Solution Approach 2:
The patent implements a universal virtual control interface that can serve multiple functions and be customized for different scenarios. The same physical steering wheel can display different virtual button configurations for various vehicle models, functions, and user preferences, eliminating the need for model-specific hardware variations.
