Wireless Power Transmission Standby Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless power transmission and reception systems face inefficiencies due to varying distances and impedance changes, leading to increased power consumption when electronic devices are in an off or standby state, as they maintain an active state to receive control signals.
Innovation Solution
Incorporating a control module that blocks power supply to the wireless power transmission module when a power off signal is received, allowing components to be turned off in standby states, reducing power consumption and preventing overvoltage issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wireless power transmission apparatus maintains an active state to receive control signals, then the control signal reception function is ensured, but the power consumption increases
Solution Approach 1:
The patent divides the wireless power transmission apparatus into separate functional modules: a control signal reception module that remains active and a power transmission module that can be turned off. This segmentation allows the reception function to operate independently while consuming minimal power, resolving the contradiction between maintaining reception capability and reducing power consumption.
Solution Approach 2:
The patent implements dynamic power management where the power transmission module can switch between active and standby states based on operational needs. The module transitions to a low-power state when no power transmission is required, while the reception module maintains operational status to receive control signals, thus dynamically balancing functionality and power consumption.
2Use of energy by moving object
If the wireless power transmission module is turned off in standby state, then the power consumption is reduced, but the power transmission capability is lost
Solution Approach 1:
The patent implements a preliminary action mechanism where the control signal reception module proactively detects incoming control signals or power requests before the power transmission module is activated. This allows the system to transition from standby to active state in advance, ensuring immediate power transmission capability when needed while maintaining low power consumption during idle periods.
Solution Approach 2:
The system dynamically adjusts the operational state of the power transmission module based on real-time demands. When a control signal or power request is detected, the module transitions from a low-power standby state to a full-power transmission state, optimizing the balance between power consumption and transmission capability according to actual operational requirements.

AI summary
An electronic apparatus is disclosed. The electronic apparatus includes a wireless power transmission module that wirelessly transmits power to a wireless power reception apparatus that is configured to supply power to a drive apparatus for an operation of an electronic apparatus, a first signal reception module that receives a control signal from a remote control apparatus, a first power supply module that supplies power to the first signal reception module, and a first control module configured to control the first power supply module. When the first signal reception module receives an off signal, the first control module controls the first power supply module such that power that is supplied to the wireless power transmission module is blocked.
