Variable Priority On-Vehicle Terminal for Dynamic Data Sorting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional on-vehicle information terminals struggle to dynamically select relevant information based on user status and preferences, as they rely on fixed priority settings that do not adapt to changing user needs.
Innovation Solution
An on-vehicle information terminal with a variable priority table that allows users to dynamically change the order of data output based on user-operated switches and instructions received from road-side communication devices, enabling real-time sorting and prioritization of information categories according to user status and preferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed priority table is used to sort data categories, then the system structure is simple and easy to operate, but the system cannot adapt to changing user needs and status
Solution Approach 1:
The patent applies the dynamics principle by making the priority table variable rather than fixed. The control section dynamically changes the priority of data categories based on user operations (button presses) and received instructions. This allows the system to adapt to changing user needs and status while maintaining a relatively simple overall structure, resolving the contradiction between adaptability and complexity.
2Ease of operation
If data is sorted according to predetermined fixed priority, then the user can obtain necessary information without paying specific attention to data sorting, but the necessary information is not always selected when user status or preference changes
Solution Approach 1:
The patent implements feedback by monitoring user operations (button presses) and using this feedback to dynamically adjust the priority table. The control section detects when a user presses a button and automatically changes the priority of the corresponding data category. This feedback mechanism allows the system to maintain ease of operation while becoming responsive to changing user preferences and status.
3Quantity of substance
If multiple data categories are output simultaneously, then comprehensive information is provided to the user, but the user burden increases due to difficulty in sorting out useful data
Solution Approach 1:
The patent applies segmentation by dividing information output into priority-based segments. The control section outputs data categories in order of their current priority, with higher priority categories presented first. This segmentation approach allows comprehensive information to be provided while reducing user burden by organizing data in a logical, priority-based sequence that makes it easier to identify and process useful information.
Data Source
AI summary
An on-vehicle information terminal that conducts communication with a road side communication device (base station) located on a road includes a transmitter/receiver section that communicates with the road side communication device, a voice output section that outputs data from the road side communication device which is received by the transmitter/receiver section through a voice or images, and a control section having a priority table that stores information on categories representative of the type of data that is added with the data and transmitted from the road side communication device and priorities for determining orders in which the voice output section outputs the data in association with each other. The priority of the priority table is variable, and is changed on the basis of a signal from a priority setting switch due to the operation of a user or an instruction signal from the road side communication device.
