Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the impeller is manually shifted and moved axially for disassembly, then the impeller can be separated from the motor, but the process requires large force and is labor-intensive due to the heavy weight of the impeller
Solution Approach 1:
The patent replaces the traditional mechanical manual shifting and axial movement system with an electromagnetic coupling system. The electromagnetic coil generates magnetic force to automatically engage and disengage the impeller from the motor, substituting heavy mechanical manual operations with a lighter electromagnetic field-based system. This resolves the contradiction by eliminating the need to manually overcome the impeller's weight and axial friction.
Solution Approach 2:
The patent introduces an electromagnetic coil as an intermediary between the impeller and the motor. This intermediary generates the biasing force that facilitates automatic engagement and disengagement, mediating the interaction between the heavy impeller and the motor without requiring direct manual force application. The electromagnetic field acts as a force multiplier, enabling easy operation despite the impeller's weight.
2Productivity
If the impeller is manually shifted a certain distance in the axial direction for disassembly, then the impeller can be separated from the motor, but the process is complicated and time-consuming
Solution Approach 1:
The patent implements a self-service disassembly and assembly mechanism where the electromagnetic coil automatically generates the biasing force needed to engage and disengage the impeller. The system performs the separation and engagement functions itself without requiring manual intervention for shifting or positioning, thereby dramatically improving productivity and eliminating time loss associated with manual operations.
Solution Approach 2:
The patent replaces the manual mechanical shifting process with an automated electromagnetic actuation system. The electromagnetic coil generates force to automatically move the impeller into or away from the motor without requiring manual axial displacement, thus resolving the time-consuming nature of traditional disassembly methods.
3Ease of manufacture
If the impeller is manually shifted and moved axially for assembly, then the impeller can be engaged with the motor, but the process requires large force and is difficult to complete due to the heavy weight of the impeller
Solution Approach 1:
The patent replaces manual mechanical assembly operations with an electromagnetic actuation system. The electromagnetic coil generates the biasing force automatically to engage the impeller with the motor, eliminating the need for manual force application against the impeller's weight. This makes assembly as easy as activating the electromagnetic coil.
Solution Approach 2:
The electromagnetic coil serves as an intermediary that provides the necessary force for engagement without requiring direct manual force application. It mediates between the heavy impeller and the motor, using electromagnetic force to overcome gravitational and frictional forces during assembly.
4Device complexity
If the impeller is manually shifted and moved axially for disassembly, then the impeller can be separated from the motor, but the process is complicated due to multiple steps and manual operations
Solution Approach 1:
The patent creates a self-service system where the electromagnetic coil automatically performs the disassembly function by generating the biasing force needed to separate the impeller from the motor. This eliminates multiple manual steps and reduces the disassembly process to a simple activation of the electromagnetic coil, thereby reducing device complexity while improving ease of operation.
Solution Approach 2:
The patent replaces complex manual mechanical disassembly operations with a simple electromagnetic actuation system. The electromagnetic coil generates force to automatically separate the impeller, replacing multiple manual steps with a single automated action, thus reducing overall system complexity.

AI summary
A control method for disassembling and assembling an impeller of an air conditioner is provided. The control method includes: controlling the electromagnetic coil (12) to control a force application direction on an impeller (10), and incorporating forward rotation or reverse rotation of a motor (20), and when the electromagnetic coil (12) is controlled to apply a force on the impeller (10) in a direction away from the motor (20), the motor (20) is rotated reversely, such that the impeller (10) is automatically separated from the motor (20), and when the electromagnetic coil (12) is controlled to apply a force to the impeller (10) in a direction approaching the motor (20), the motor (20) is rotated forward, and the impeller (10) is automatically engaged with the motor (20), so that the impeller (10) can be automatically disassembled or assembled, thus reduce manual operation and improve operation efficiency.
