Air Flow Image Generation for Car Ventilation Visualization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional techniques fail to provide passengers with an easy way to know the ventilation situation inside a passenger car.
Innovation Solution
A presentation information generation device that includes air flow calculating circuitry to acquire ventilation equipment information, presentation information generating circuitry to generate air flow images, and presentation information output circuitry to display these images, allowing passengers to visualize the ventilation situation using air flow information and a database storing relationships between ventilation states and air flows.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If ventilation control device only variably controls ventilation equipment, then ventilation amount is adjusted according to car load, but passenger cannot easily know ventilation situation in car interior
Solution Approach 1:
The patent applies color changes to indicate different ventilation states. The display shows color-coded information representing air flow conditions, allowing passengers to quickly understand the ventilation situation without complex data interpretation. Different colors correspond to different ventilation modes or air flow levels, making the information immediately recognizable.
Solution Approach 2:
The patent creates a visual copy or representation of the actual ventilation state through display elements. The display device generates graphical representations (such as arrows, color zones, or icons) that mirror the physical air flow conditions in the car interior, allowing passengers to perceive the ventilation situation indirectly through this visual copy.
2Loss of information
If no presentation information is provided, then device complexity is low, but passenger cannot understand ventilation situation
Solution Approach 1:
The presentation information generation device integrates multiple functions into a single system. It acquires ventilation equipment information, calculates air flow based on this information, generates appropriate presentation content, and displays it all through one integrated device. This multi-functional approach minimizes the need for separate systems while comprehensively addressing information presentation needs.
Solution Approach 2:
The patent introduces an intermediary calculation process that transforms raw ventilation equipment data into meaningful air flow information. The air flow calculation unit acts as a mediator between the ventilation control device and the display, converting technical parameters into passenger-understandable presentation information about ventilation conditions.

AI summary
A presentation information generation device includes: an air flow calculating unit that acquires ventilation equipment information indicating a state of ventilation equipment in a passenger car, and outputs air flow information regarding an air flow in a car interior of the passenger car by using the ventilation equipment information; a presentation information generating unit that generates and outputs an air flow image indicating a state of the air flow in the passenger car by using the air flow information output by the air flow calculating unit; and a presentation information output unit that causes a presentation device to present the air flow image output from the presentation information generating unit.
