Solution Overview
Problem
The air conditioning industry faces issues with motor software vulnerabilities leading to potential large-scale motor discarding due to unreflected real-world usage scenarios in software testing, resulting in increased post-sale costs and reduced efficiency.
Innovation Solution
A programmable motor with a reprogramming interface that allows direct software updates and parameter modifications without disassembling the driving device, using a programming device to communicate and update motor software programs through a sealed reprogramming interface, reducing post-sale costs and improving efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If software testing is performed without fully reflecting actual use scenarios, then software development time is reduced, but software vulnerabilities increase leading to motor discarding
Solution Approach 1:
The patent applies preliminary action by pre-configuring a reprogramming interface and retaining backdoor access capabilities during the software development phase. This allows the motor to be reprogrammed later without disassembly, preventing the need to discard motors due to software vulnerabilities while maintaining efficient initial development cycles.
2Reliability
If the driving device is disassembled for software reprogramming, then software vulnerabilities can be fixed, but post-sale costs increase and efficiency decreases
Solution Approach 1:
The patent segments the reprogramming function from the main driving device structure by providing a dedicated reprogramming interface. This allows software updates to be performed independently without disassembling the entire driving device, reducing post-sale costs and improving service efficiency while maintaining motor reliability.
Solution Approach 2:
The patent introduces a reprogramming interface as an intermediary component that enables communication between the external programming device and the motor control system. This intermediary allows software vulnerabilities to be fixed without direct access to the internal driving device structure, reducing service costs and improving efficiency.
3Productivity
If a reprogramming interface is provided on the driving device, then motor reprogramming efficiency is improved, but device complexity increases
Solution Approach 1:
The patent extracts the reprogramming function from the main driving device control logic and provides it through a dedicated interface. This separation allows efficient software updates without complicating the core driving device structure, as the reprogramming interface operates independently from the motor control functions.

AI summary
Provided are a programmable motor and a household appliance having the same. The programmable motor comprises a main body (21) and a driving device (22) comprising a reprogramming interface. When performing reprogramming on the programmable motor, the reprogramming interface communicates with a programming device to receive a motor parameter or a motor software program, to transmit the same to the driving device (22), and to update the motor parameter or the motor software program in the driving device (22). The method realizes rewriting of a motor software program and realizes reprogramming of a motor by directly inserting a programming device into a reprogramming interface of a driving device (22) without having to disassemble the driving device (22), thereby effectively reducing post-sale costs associated with a motor, and improving post-sale efficiency associated with the motor.
