Vehicle Indicator Data Output Device Reducing Processing Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle maintenance reporting devices face high data processing loads when notifying users of maintenance timing, as they need to manage and visualize multiple management items to convey the increase in vehicle usage amount, leading to increased complexity and processing demands.
Innovation Solution
An indicator data output device and method that uses a simplified approach by storing vehicle identification data and indicator data, obtaining vehicle usage amount data, and updating indicator data based on usage, allowing users to grasp usage increases through dimensionless indicators, thereby reducing data processing load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple management items are managed and visualized to notify the increase in vehicle usage amount, then the user can grasp the usage amount in detail, but the data processing load on the device becomes large
Solution Approach 1:
The patent segments the vehicle usage amount information into multiple management items (e.g., engine driving period, usage period of vehicle component, stoppage period, total traveling distance) and processes only the necessary segments for the notification purpose, rather than processing all raw data comprehensively
Solution Approach 2:
The patent extracts only the essential management items needed for maintenance timing notification from the complete vehicle usage data set, eliminating unnecessary data processing while preserving the critical information required for the notification function
2Measurement precision
If the number of management items increases to notify maintenance timing more accurately, then the maintenance timing notification becomes more accurate, but the data processing load on the device increases
Solution Approach 1:
The patent applies different processing qualities to different management items based on their relevance to maintenance timing, focusing computational resources on the most critical items (such as engine driving period and usage period of vehicle component) while using simplified processing for less critical items
Solution Approach 2:
The patent changes the parameter representation of management items by converting raw usage data into standardized management item metrics that are optimized for maintenance timing calculation, reducing the computational complexity while maintaining notification accuracy
