Content Distribution Server Movement Means Determination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing content distribution systems inaccurately determine the movement means of users, leading to incorrect content distribution, particularly when users travel by public buses or encounter traffic congestion, as they rely solely on movement rates without considering route limitations or current mobility conditions.
Innovation Solution
A content distribution server that acquires and utilizes activation and position information from in-vehicle devices to determine whether a user can visit a facility by vehicle, allowing for accurate content distribution based on this information, and includes features like customer management databases and linkage information to associate mobile terminals with vehicles, enabling precise movement means determination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If movement rate alone is used to determine movement means, then the determination process is simple, but the determination accuracy deteriorates
Solution Approach 1:
The patent segments the determination process into multiple independent analysis dimensions: movement rate analysis, position information analysis (for route limitation detection), and activation information analysis. Each dimension provides specific indicators that are collectively evaluated to determine movement means, avoiding reliance on a single metric while maintaining systematic analysis.
Solution Approach 2:
The patent transitions from one-dimensional movement rate analysis to multi-dimensional analysis by incorporating position information (spatial dimension) and activation information (temporal/state dimension). This dimensional expansion enables the system to detect route limitations and traffic conditions, significantly improving movement means determination accuracy.
2Ease of operation
If only movement rate is considered, then the system operation is simple, but incorrect content distribution occurs
Solution Approach 1:
The patent implements feedback mechanisms where position information and activation information continuously inform the movement means determination. The system uses position information to detect route limitations (feedback on spatial constraints) and activation information to identify traffic snarl-ups (feedback on temporal constraints), then adjusts content distribution decisions based on this feedback, ensuring accuracy while maintaining operational simplicity.
Solution Approach 2:
The patent introduces position information and activation information as intermediary elements that mediate between the simple movement rate measurement and the complex content distribution decision. These intermediaries translate raw data into meaningful indicators of route limitations and traffic conditions, enabling accurate content distribution without complicating the overall system operation.
3Measurement precision
If comprehensive information is collected from in-vehicle devices, then movement means determination accuracy is improved, but information processing complexity increases
Solution Approach 1:
The patent extracts only the essential and relevant information elements from in-vehicle devices: movement rate, position information (for route limitation detection), and activation information (for traffic condition detection). By selectively extracting only these critical parameters and discarding redundant data, the system maintains high determination accuracy while avoiding excessive information processing complexity.
Data Source
AI summary
A content distribution server is provided with: a storage unit, which stores a plurality of pieces of content related to a facility; an acquisition unit, which acquires, from an in-vehicle navigation device of the vehicle, any one or both of starting information on a vehicle and location information on the vehicle, as information for determination; and a content distribution unit, which distributes content stored in the storage unit to a mobile terminal. The content distribution unit determines, on the basis of the information for determination acquired by the acquisition unit, whether a user can visit the facility by the vehicle, and determines, on the basis of the determination result, which content in the plurality of pieces of content stored in the storage unit is distributed to the mobile terminal.
