Solution Overview
Problem
The existing IoT system designs for managing equipment often result in excessive specifications and unpredictable operation costs due to the need to withstand peak loads, particularly when using auto-scaling methods.
Innovation Solution
The equipment management system incorporates a management apparatus with a receiving unit, load detecting unit, load determining unit, and reduction control unit that detects and manages loads above a threshold value, allowing for reduction control without increasing specifications, by adjusting communication conditions and prioritizing equipment information transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the management apparatus is designed to withstand peak load using auto-scaling, then the system can handle high load periods, but the operation cost becomes unpredictable and specifications become excessive
Solution Approach 1:
The patent implements dynamic load management by enabling the management apparatus to flexibly adjust resource allocation based on real-time load conditions. The system dynamically switches between normal processing mode and peak load handling mode, allowing it to adapt to varying demand without requiring permanent over-provisioning of resources. This dynamic approach resolves the contradiction by providing peak load capability only when needed, rather than maintaining excessive specifications continuously.
Solution Approach 2:
The system changes operational parameters based on load levels, specifically adjusting the acceptance of new requests and the processing priority of existing requests. When peak load is detected, the system modifies parameters such as request acceptance thresholds and processing priorities to maintain reliability. This parameter-based adaptation allows the system to handle peak loads without permanently increasing specifications, as the high-capacity state is temporary and condition-driven.
2Reliability
If the management apparatus processes all requests during peak load, then service quality is maintained, but the load on the processing unit becomes unmanageable
Solution Approach 1:
The patent ensures continuous service quality during peak load by implementing a prioritized processing mechanism. High-priority requests continue to be processed without interruption, maintaining essential service continuity. The system distinguishes between critical and non-critical requests, ensuring that useful actions (processing essential requests) continue uninterrupted while non-essential processing is deferred or rejected. This maintains service quality for critical functions without overwhelming the processing unit.
Solution Approach 2:
The system extracts and separates high-priority requests from the general request queue during peak load conditions. By identifying and extracting critical requests that must be processed, the system ensures service quality for essential functions. Non-critical requests are either rejected or deferred to lower-priority processing queues, effectively removing the burden of processing all requests simultaneously and preventing processing unit overload while maintaining essential service quality.
