Outdoor Unit Voltage-Triggered Reset Without Physical Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing outdoor device unit (ODU) reset process is time- and effort-consuming, requiring users to physically access the device, remove a waterproof cover, and manually trigger a reset switch, which is inefficient and inconvenient.
Innovation Solution
A voltage regulation apparatus is connected to the ODU, which regulates the working voltage based on a feedback signal, allowing the ODU to determine when a change in voltage is within a preset range and perform a reset operation remotely, thereby simplifying the reset process and avoiding the complexity of triggering a physical reset switch.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a reset switch is provided on the outdoor device unit, then the reset operation can be performed, but the user needs to physically access the device which is time- and effort-consuming
Solution Approach 1:
The patent introduces a voltage regulation apparatus as an intermediary between the power supply and the outdoor device unit. By manipulating the voltage regulation apparatus (specifically by adjusting the feedback signal to change the working voltage), the user can trigger a reset operation without physically accessing the outdoor device unit. This mediator enables remote reset operation, resolving the contradiction between operational convenience and time consumption.
Solution Approach 2:
The patent replaces the mechanical reset switch operation with an electrical control mechanism. Instead of physically pressing a reset switch on the outdoor device unit, the user controls the voltage regulation apparatus electrically (through voltage adjustment). This substitution of mechanical operation with electrical control eliminates the need for physical access and reduces reset operation time.
2Ease of operation
If the reset switch is on the outdoor device unit, then resetting is possible, but the operation complexity increases due to needing to remove waterproof cover and access the device
Solution Approach 1:
The voltage regulation apparatus serves as an intermediary that simplifies the reset process. Instead of the user directly interacting with the outdoor device unit (which requires removing waterproof covers and accessing internal components), the user interacts with the voltage regulation apparatus which is more accessible. This intermediary approach reduces operational complexity while maintaining the reset functionality.
Solution Approach 2:
The patent extracts the reset trigger function from the outdoor device unit itself and places it in the voltage regulation apparatus. By taking out the reset initiation capability from the remote outdoor device and placing it in the accessible voltage regulation apparatus, the system simplifies the user interaction required for resetting while preserving the reset functionality.
3Ease of operation
If remote reset is implemented through voltage regulation, then operation convenience is improved, but additional control function complexity is added to the voltage regulation apparatus
Solution Approach 1:
The voltage regulation apparatus is designed to perform multiple functions: its primary function of voltage regulation and an additional function of triggering reset operations. By making the voltage regulation apparatus multi-functional, the patent avoids adding a separate dedicated reset mechanism, thereby implementing remote reset capability without significantly increasing overall system complexity.
Solution Approach 2:
The patent merges the voltage regulation function and the reset trigger function into a single integrated apparatus. The voltage regulation apparatus not only regulates voltage but also serves as the control interface for initiating reset operations. This merging of functions reduces the number of separate components needed and simplifies the overall system architecture while enabling remote reset.

AI summary
An outdoor device reset system includes a voltage regulation apparatus coupled to a power supply apparatus and an outdoor device coupled to the voltage regulation apparatus. The voltage regulation apparatus is configured to regulate a working voltage input to the outdoor device based on a feedback signal, a supply voltage from the power supply apparatus for the voltage regulation apparatus, and a reference voltage of the voltage regulation apparatus. The outdoor device is configured to determine a change amount of the working voltage, and perform a reset operation when the change amount is within a preset range.
