Solution Overview
Problem
Existing inverters are difficult to monitor and control remotely, especially when placed in hard-to-reach locations, leading to issues with status display failure, inefficient battery management, and constant draught fan noise, which results in early battery discharge or over-discharge.
Innovation Solution
An inverter device with a wireless communication module and display panel connected via a flexible cable, allowing remote control and monitoring through Bluetooth, Wi-Fi, or 2.4G networks, and incorporating a test module and draught fan controller for variable speed operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the inverter is fixed at a corner with wired remote control, then users can control on-off state remotely, but the display panel cannot be observed in time and wireless communication may fail when placed in hard-to-reach locations
Solution Approach 1:
The inverter system is divided into two independent parts: the main body (power conversion unit) and the display panel (control unit). The display panel can be placed at any location within flexible wire range, allowing users to observe status information and control the inverter remotely without being constrained by the main body's location.
Solution Approach 2:
A flexible wire serves as an intermediary connection between the display panel and the main body, enabling both power supply and data transmission. This intermediary allows the display panel to be positioned far from the main body while maintaining functional connectivity.
2Temperature
If the draught fan operates in sole 'on'-state, then cooling function is provided, but noise is relatively big and cannot be switched off individually
Solution Approach 1:
The draught fan controller enables the fan to operate in multiple states (off, low speed, high speed) rather than a fixed on/off mode. Users can dynamically adjust the fan's operation based on actual cooling needs, reducing noise when full cooling is not required.
Solution Approach 2:
The system provides feedback about the inverter's operating state and temperature conditions, allowing the draught fan controller to adjust fan speed appropriately. This feedback mechanism enables the fan to run at lower speeds when cooling demand is low, reducing noise while maintaining effective cooling when needed.
3Device complexity
If the inverter lacks timing function and battery state monitoring, then device is simple, but user cannot know battery state and may cause early switching-off or over-discharging
Solution Approach 1:
The inverter continuously monitors battery state (charge level, temperature, health) and provides real-time feedback to users through the display panel. This feedback enables users to make informed decisions about when to switch the inverter off, preventing both early shutdown and over-discharging.
Solution Approach 2:
The timing function allows the inverter to be set in advance for automatic on/off operations. Users can preset operation schedules before leaving, and the inverter will automatically execute these pre-programmed actions, eliminating the need for manual intervention and ensuring reliable battery management.

AI summary
The present invention relates to an inverter device. Regard to the problem in the traditional convert device that the user is difficult to obtain the information shown on the display panel in time; the state of the inverter can not be switched remotely after the user leaves; discharging or early switching-off caused by missing battery information; and the draught fan can only be at the state of ‘full-speed-start’ or switch-off, the invention provides an inverter device, it is configured with an extensible flexible wire to fix the display panel of the inverter to the place the user wants to for getting the information of the inverter in time; by virtue of wireless transmission, user can control the state of the inverter remotely; by adding a test module to the inverter device, it avoids the waste of electricity which is caused by the discharging of the battery-to-convert and switching off.
