Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional navigation systems display vehicle driving status in two-dimensional formats, which may not effectively convey the operational status suited to specific usage purposes, making it difficult to understand the driving conditions intuitively.
Innovation Solution
A travel route display device and method that incorporates a display unit, topographical data storage, and a control unit to simultaneously display three-dimensional topographical data and travel route data in a mode corresponding to the vehicle's driving status, using GPS and other sensors to acquire and process data such as speed, acceleration, and gradient, and adjust the display mode (color, width, thickness, or dot size) based on these parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional two-dimensional display methods are used for vehicle driving status, then the display system remains simple and easy to implement, but the intuitiveness and ease of understanding the driving conditions deteriorates
Solution Approach 1:
The patent transitions from conventional two-dimensional display to three-dimensional topographical display, adding a vertical dimension to represent elevation and terrain features. This dimensional enhancement allows drivers to intuitively understand driving conditions such as gradients, elevation changes, and terrain difficulty, directly resolving the contradiction between display simplicity and ease of understanding.
Solution Approach 2:
The patent applies different visual properties to different sections of the travel route based on local driving conditions. Specific display modes are assigned to different route segments according to their characteristics (e.g., steep gradients, high speed sections, sharp curves), allowing drivers to quickly identify and understand critical local conditions without overwhelming the entire display.
2Loss of information
If multiple display modes are used to represent different driving statuses, then the information completeness and suitability for specific usage purposes improves, but the device complexity and difficulty of implementation increases
Solution Approach 1:
The patent implements dynamic display modes that automatically adjust based on real-time driving status parameters such as speed, gradient, and acceleration. The control unit dynamically selects and switches between different display modes according to the current driving conditions, ensuring complete and accurate information representation without requiring manual intervention or complex configuration.
Solution Approach 2:
The patent uses changes in display parameters (color, width, thickness, dot size) to represent different driving status parameters. By mapping physical driving parameters to visual display parameters, the system achieves comprehensive information representation through systematic parameter correspondence, reducing the complexity of implementing multiple display modes.
3Ease of operation
If three-dimensional topographical data is displayed with multiple display modes corresponding to different driving statuses, then the ease of understanding and visual representation quality improves, but the data processing complexity and computational requirements increases
Solution Approach 1:
The patent applies different visual display modes to different local sections of the travel route based on their specific characteristics. By processing and displaying only the relevant features of each route segment with appropriate visual properties, the system achieves high visual understanding quality while avoiding the need to process and render every detail uniformly, thus reducing overall computational complexity.
