Power Saving Module Switching Battery Disconnection for Shipping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electrical devices experience excessive power consumption during long-term shipping and standby, leading to battery over-discharge and potential inability to recharge, especially when in sleep mode, resulting in startup failures upon arrival.
Innovation Solution
An electrical device comprising a power saving module electrically coupled to the battery module and OS system, with a switch module controlling the connection or disconnection between them, allowing switching between power saving, sleep, and run modes, utilizing an electrical switch, voltage pull elements, and an inverter to manage power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electrical device is placed in sleep mode during long-term shipping, then the device is protected and ready for use, but the battery power is consumed excessively leading to over-discharge
Solution Approach 1:
The patent applies preliminary action by completely disconnecting the battery module from the OS system before long-term shipping using a switch module. This prevents any standby power consumption during transit while ensuring the device can be quickly reconnected and activated upon arrival, resolving the contradiction between device readiness and battery power conservation
Solution Approach 2:
The patent extracts the battery module's electrical connection from the OS system by introducing a switch module that can completely disconnect them. This separation allows the battery to be isolated during shipping, eliminating parasitic power consumption while maintaining the capability to reconnect when needed
2Ease of operation
If the electrical device remains in run mode during shipping, then immediate use is possible upon arrival, but the battery power is depleted completely
Solution Approach 1:
The switch module is pre-configured to disconnect the battery during shipping, and upon arrival, users can simply activate the device without worrying about power management. The preliminary disconnection action ensures battery preservation while maintaining ease of operation upon arrival
3Use of energy by moving object
If the electrical device is shipped in power saving mode, then battery power is conserved, but the device cannot start up after arrival due to over-discharge
Solution Approach 1:
The patent extracts the battery connection entirely during shipping rather than relying on power saving modes. This complete disconnection prevents even minimal power consumption that could lead to over-discharge, ensuring the battery retains sufficient charge for reliable startup upon arrival
Solution Approach 2:
The switch module performs a preliminary anti-action by preventing any power drain on the battery during shipping. This preemptive disconnection counteracts the potential harmful effect of power consumption that would otherwise lead to over-discharge and startup failure

AI summary
The present invention provides an electrical device having a power saving mode, a sleep mode, and a run mode of an OS system. A modality switch controls an on-off of the battery module and the OS system for achieving to switch between the power saving mode and other modes. The power saving method mentioned above can apply to the shipment and the storage of the electrical device to reduce the power consumption of the battery.
