Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In a ubiquitous society, intermittent communication between sensors and devices leads to a buildup of sensor data, causing a sudden load and battery consumption issues when communication is reestablished, resulting in inconvenience to users.
Innovation Solution
A method and apparatus for managing sensor data by receiving data from sensors, checking communication connection states, and selectively transmitting data based on user queries and allowable delay limits, using a First-In First-Out policy and data storage policies to reduce the amount of data transmitted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If sensor data is continuously transmitted to the mobile device, then the user receives real-time information, but battery consumption increases rapidly and device malfunction may occur due to continuous load
Solution Approach 1:
The patent implements periodic transmission by checking communication connection states at intervals and transmitting sensor data only when connection is available. The system transitions between active transmission and standby states, avoiding continuous operation. This periodic approach maintains information delivery while significantly reducing energy consumption compared to continuous transmission.
2Loss of information
If sensor data is transmitted after communication disconnection, then all accumulated data is sent, but sudden load increase causes battery consumption and device malfunction
Solution Approach 1:
The patent segments accumulated sensor data into multiple transmission batches rather than transmitting all data at once. The data buffer is divided into smaller units that are transmitted sequentially over multiple communication cycles. This segmentation prevents sudden load spikes, maintains device stability, and ensures reliable transmission of all accumulated information.
3Loss of information
If all sensor data is transmitted whenever communication restarts, then complete data is delivered, but the sudden increase in data amount causes rapid battery consumption
Solution Approach 1:
The patent applies partial action by transmitting only a portion of accumulated sensor data in each communication cycle rather than all data at once. The system transmits data in controlled amounts across multiple cycles, balancing data completeness with energy conservation. This approach delivers complete information over time while avoiding the energy waste of single-batch transmission.
4Productivity
If communication connection is maintained continuously, then data transmission is smooth, but energy consumption increases due to constant connection state
Solution Approach 1:
The patent implements dynamic connection management by transitioning the communication interface between active and inactive states based on connection availability. The system dynamically adjusts its operation mode: actively transmitting when connected, and entering standby when disconnected. This dynamic approach optimizes the balance between transmission efficiency and energy consumption.

AI summary
Provided are an apparatus and method for transmitting only sensor data actually used to process a user request among sensor data received from a sensor when communication restarts between a sensor data management device and a sensor data analysis device. Accordingly, the amount of data transmitted to the sensor data analysis device is reduced. The sensor data analysis device may analyze the sensor data received from the sensor data management device to process the user request.
