Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data exchange systems between information-processing devices are inflexible, as they rely on constant temporal and spatial ranges, which can limit data exchange opportunities in areas with low spatial density, such as rural areas.
Innovation Solution
A server device that determines data exchange conditions based on location information and spatial density, allowing for dynamic adjustment of temporal and spatial ranges to facilitate data exchange between devices within a communication system.

Engineering Contradiction Analysis
1Adaptability or versatility
If constant temporal and spatial ranges are used for data exchange, then the system is simple to operate, but data exchange opportunities are limited in areas with low spatial density
Solution Approach 1:
The patent applies dynamics by making the temporal and spatial ranges adjustable rather than fixed. The server dynamically modifies these parameters based on spatial density information, allowing the system to adapt to different environments (urban vs. rural areas) and increase data exchange opportunities without requiring completely different system designs for different regions.
Solution Approach 2:
The patent changes the parameters of temporal and spatial ranges based on spatial density. When spatial density is low (rural areas), the server increases the spatial range and/or temporal range to allow data exchange between devices that are farther apart or have been apart longer, thereby adapting the system to low-density environments while maintaining simplicity through automated parameter adjustment.
2Productivity
If the spatial range is increased to reach more devices, then data exchange opportunities increase, but the precision of location-based matching decreases
Solution Approach 1:
The patent applies local quality by adjusting the spatial and temporal ranges according to local spatial density conditions. In high-density urban areas, smaller and more precise ranges are used, while in low-density rural areas, larger and more flexible ranges are applied. This allows the system to maintain appropriate precision locally while increasing overall data exchange opportunities across different regions.
Solution Approach 2:
The system dynamically adjusts the spatial and temporal ranges based on real-time or contextual spatial density information. Rather than using fixed ranges, the server modifies these parameters to balance between reaching more devices and maintaining meaningful location-based matching, with the range size adapting to the local device distribution density.
3Adaptability or versatility
If fixed data exchange conditions are used, then the system is easy to implement, but it cannot adapt to different spatial density environments
Solution Approach 1:
The patent introduces a server as an intermediary that handles the complex task of determining and adjusting data exchange conditions based on spatial density. Instead of requiring individual devices to implement complex adaptability logic, the server centralizes this function, receiving location information, calculating spatial density, and determining appropriate temporal and spatial ranges, thereby achieving environmental adaptability without significantly increasing device complexity.
Solution Approach 2:
The system achieves environmental adaptability by changing the temporal and spatial range parameters based on spatial density information. The server automatically adjusts these parameters according to whether the environment is urban (high density) or rural (low density), allowing the same system to adapt to different environments without requiring manual configuration or complex device-side decision-making.
