Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of centralized control in multi-split air conditioning systems, particularly due to complex wiring or debugging processes, leads to inefficiencies and instability in managing outdoor and indoor units, especially in large commercial settings.
Innovation Solution
A centralized control method that uses a debugging terminal to acquire an outdoor unit's identification code, send requests to a cloud server for system information, create a project, upload project information, and generate a delivery code, allowing a centralized control device to load and activate the project without communication wiring or network debugging, simplifying the management process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired communication is used for centralized control, then control stability is improved, but wiring complexity increases
Solution Approach 1:
The patent replaces the mechanical wiring system with a wireless communication system. The centralized control device communicates with outdoor and indoor units through wireless signals, eliminating the need for complex physical wiring while maintaining control functionality. This substitution resolves the contradiction by removing the mechanical constraint (wiring) that caused complexity.
2Device complexity
If wireless communication is used for centralized control, then wiring complexity is reduced, but debugging complexity and communication stability worsen
Solution Approach 1:
The patent implements preliminary action by pre-configuring communication parameters and establishing connection protocols before actual centralized control operation. The system performs automatic device discovery, network topology detection, and communication parameter negotiation during initial setup, eliminating the need for manual debugging later. This preliminary configuration resolves the debugging complexity issue.
3Device complexity
If wireless communication is used for centralized control, then wiring complexity is reduced, but communication stability worsens due to building structure
Solution Approach 1:
The patent introduces a gateway device as an intermediary between the centralized control device and indoor units. The gateway receives control signals, processes them, and forwards appropriate commands to target devices. This intermediary layer stabilizes communication by handling signal routing, error correction, and protocol conversion, compensating for the instability caused by building structures blocking direct wireless signals.
4Reliability
If traditional centralized control implementation process is used, then control functionality is achieved, but implementation complexity increases
Solution Approach 1:
The patent uses copying by creating a virtual representation of the air conditioning system topology in the centralized control device. Instead of directly mapping physical connections, the system creates a logical model that mirrors the actual device relationships. This virtual copy simplifies control implementation by allowing configuration and management through the simplified virtual model rather than dealing with complex physical wiring details.
