Solution Overview
Problem
Existing circuit board replacement methods require special configurations in both the remote controller and indoor unit for data transfer, which can be cumbersome and prone to failure, especially when the CPU or power source circuit fails, and detachable storage media pose risks of damage during attachment and detachment.
Innovation Solution
A circuit board design with a disconnection unit that allows for safe and quick data transfer between old and new boards by disconnecting power and signal wires, using a common connector configuration for both boards to facilitate data replication without additional tools or components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a detachable storage medium is used for data transfer, then data can be transferred between devices, but the storage medium may be damaged during attachment and detachment
Solution Approach 1:
The patent extracts the storage medium from the circuit board, allowing it to be detached for data transfer between devices. This enables portable data movement while maintaining the ability to securely store data when attached to the circuit board.
Solution Approach 2:
The patent provides protective structures and handling guidelines for the detachable storage medium to prevent damage during attachment and detachment operations, cushioning against potential mechanical stress before it causes failure.
2Ease of operation
If special configurations are added to remote controller and indoor unit for data transfer, then data can be transferred, but device complexity increases
Solution Approach 1:
The detachable storage medium serves multiple functions: it acts as a data transfer interface between different devices, provides local storage capacity, and enables configuration synchronization without requiring special dedicated hardware in each device.
Solution Approach 2:
The storage medium acts as an intermediary carrier for data transfer between the indoor unit and remote controller, eliminating the need for direct communication protocols or special configurations in both devices.
3Reliability
If the CPU or power source circuit fails, then the device cannot operate, but data transfer to remote controller becomes impossible
Solution Approach 1:
The patent segments the data storage function from the processing units (CPU and power source circuit). By storing data on a detachable medium rather than in volatile memory tied to the CPU, data can be preserved and transferred even when processing components fail.
Solution Approach 2:
The patent enables copying of data from the indoor unit to the remote controller via the detachable storage medium, creating redundant data copies that can be restored if the original system fails.
