Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If detailed driving efficiency information is displayed using traditional methods, then information completeness is improved, but driver comprehension speed and intuitiveness deteriorate
Solution Approach 1:
The display information is segmented into distinct visual elements: a main graphical element representing current driving efficiency, a position of equilibrium representing optimal efficiency, and auxiliary graphical elements providing additional context. This segmentation allows the driver to quickly grasp the main message (current vs. optimal efficiency) while auxiliary elements provide detailed information only when needed.
Solution Approach 2:
The patent transitions from traditional text or numerical displays to a spatial, visual dimension. The main graphical element's position in space relative to the position of equilibrium visually encodes efficiency information, allowing drivers to comprehend driving efficiency status at a glance through spatial relationships rather than reading or interpreting numbers.
2Measurement precision
If multiple variables and data points are presented to the driver, then information accuracy is improved, but driver focus on road conditions deteriorates
Solution Approach 1:
The patent extracts the essential driving efficiency information from multiple variables and presents it through a simplified visual metaphor. The main graphical element's position relative to the position of equilibrium captures the core efficiency status, while auxiliary elements provide additional precision only when the driver chooses to examine them, preventing information overload.
Solution Approach 2:
Different parts of the display have different levels of information density. The main graphical element and its position relative to equilibrium provide high-level efficiency information for quick comprehension, while auxiliary graphical elements provide localized, detailed information only in specific areas when drivers need more precision, allowing selective information processing.

AI summary
A method and associated device for displaying information pertaining to efficient driving of a motor vehicle (5), wherein an image (2) is displayed on a graphical display device (1) by means of a control device (4), wherein said graphical image comprises a main graphical element (231) that moves away from a position of equilibrium (22) at a distance proportional to a variation in vehicle speed (5). In this way, the information related to the decrease in driving efficiency is presented in a highly visual and intuitive manner, particularly in respect of the more or less abrupt variations in vehicle speed.
