Wireless Terminal Temporary Information Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems using near field communication struggle to accurately provide information relevant to a user's current location and time, as information stored in databases may be outdated and temporal communication opportunities are limited, leading to inaccurate search results due to changes in shop conditions or restricted communication windows.
Innovation Solution
A wireless communication terminal and method that transmits and receives 'temporarily remaining information' linked with place and time to a communication base station, storing and deleting this information after a predetermined time, allowing for real-time information acquisition and ensuring accuracy based on the user's current location and time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If information is stored in a database for future retrieval, then information can be accessed later, but the information becomes outdated and inaccurate over time
Solution Approach 1:
The patent implements temporarily remaining information that automatically expires after a predetermined time period. This disposable information approach ensures that only current and relevant information is available, preventing outdated data from causing inaccuracies while maintaining information freshness through continuous updates.
Solution Approach 2:
The system dynamically manages information validity periods, allowing information to remain accessible only within a specified time window. This dynamic approach ensures that information accuracy is maintained by automatically expiring old data while providing timely access to current information through the temporarily remaining information mechanism.
2Reliability
If near field communication is used for information exchange, then communication occurs in real-time, but communication opportunities are restricted by temporal and spatial limitations
Solution Approach 1:
The system performs preliminary actions by storing information in advance at communication base stations before actual communication needs arise. This allows the terminal to acquire temporarily remaining information from multiple base stations during movement, ensuring communication availability is maintained while increasing flexibility through pre-positioned information resources.
Solution Approach 2:
Communication base stations serve as intermediaries that store and manage temporarily remaining information. These intermediaries enable the terminal to access real-time information without direct real-time communication with the original information source, thereby maintaining communication reliability while expanding adaptability through indirect information acquisition channels.
3Quantity of substance
If information is retained indefinitely in storage, then all historical data is available, but storage resources are wasted and data quality deteriorates
Solution Approach 1:
The patent implements automatic discarding of temporarily remaining information after a predetermined time period expires. This selective discarding mechanism maintains information quality by removing outdated data while preserving valuable current information, ensuring that storage resources are efficiently utilized and data reliability is maintained through continuous purification of the information pool.

AI summary
A wireless communication terminal includes: a wireless communication part configured to transmit temporarily remaining information, which is information linked with place and time, to a communication base station and receive the temporarily remaining information stored in the communication base station from the communication base station; a storage device in which the temporarily remaining information received by the wireless communication part is stored; and a deletion part configured to, after receipt of the temporarily remaining information, delete the temporarily remaining information having passed a predetermined time specified in advance.
