Solution Overview

Problem

IoT networks face limitations in the number of terminal apparatuses that can be connected to an edge device, leading to a situation where additional terminal apparatuses with higher priority data cannot be collected when the connection limit is reached, as only data from already connected apparatuses are acquired.

Innovation Solution

A data collection apparatus with a connecting unit, storing unit, and controller that prioritizes connections based on stored priority levels, allowing a terminal apparatus with a higher priority level to connect in place of one with a lower priority level when the connection limit is exceeded, ensuring that higher priority data is collected.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the data collection apparatus connects to a limited number of terminal apparatuses simultaneously, then the connection management is simplified and stable, but the apparatus cannot accept additional terminal apparatuses with higher priority data when the connection limit is reached

Engineering Contradiction:
Improveconnection stabilityVSAvoidflexibility to accept additional connections
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic connection management by continuously monitoring the number of connected terminal apparatuses and automatically establishing or terminating connections based on real-time conditions. When the connection limit is reached, the system dynamically evaluates priority levels of waiting terminal apparatuses and terminates connections with lower priority terminals to accommodate higher priority ones, making the connection capacity flexible rather than static.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the parameter of connection priority by introducing priority level information for each terminal apparatus. The system uses these priority parameters to make intelligent connection decisions, where the effective connection limit becomes variable based on priority levels rather than a fixed number, allowing higher priority terminals to displace lower priority ones when resources are constrained.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If the data collection apparatus prioritizes connection with terminal apparatuses having higher priority levels, then higher priority data is collected more effectively, but the system complexity increases due to priority level management

Engineering Contradiction:
Improvedata collection efficiencyVSAvoidconnection management complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by pre-establishing priority levels for each terminal apparatus before connection decisions are made. The data collection apparatus stores priority level information in advance, allowing it to quickly determine connection priorities without complex real-time evaluations, thus reducing the actual computational complexity during operation while maintaining high data collection efficiency.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent uses copying by creating a simplified representation of connection priorities through stored priority level data. Instead of managing complex connection rules and real-time negotiations, the system copies the essential priority information into a straightforward numerical or hierarchical format that can be easily compared and acted upon, reducing management complexity while preserving productivity.

Inventive Principle:
Principle #26Copying

AI summary

A data collection apparatus includes a connecting unit, a storing unit, and a controller. The connecting unit is able to be connected through communication with a limited number of terminal apparatuses. The storing unit stores priority levels regarding connection with the terminal apparatuses. The controller allows, in a case where the number of terminal apparatuses that are present in a region in which the data collection apparatus is able to be connected through communication with a terminal apparatus via the connecting unit is larger than the limited number, a terminal apparatus that is not connected through communication with the connecting unit and has a higher priority level to be connected with the connecting unit, in place of a terminal apparatus that has already been connected through communication with the connecting unit and has a lower priority level, in accordance with the stored priority levels.
