Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air cleaners have limited capacity and difficulty in purifying air across entire indoor spaces due to restricted rotation of flow switching devices caused by power connections, leading to inefficient air distribution.
Innovation Solution
The implementation of a wireless power transmission system between the air blowing device and the flow switching device allows for 360-degree rotation without twisting cables, simplifying the power connection process and ensuring stable power supply to the flow switching device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wired power connection is used between the air blowing device and the flow switching device, then power can be supplied reliably, but the rotation of the flow switching device is limited due to cable twisting
Solution Approach 1:
The patent replaces the mechanical wired power connection system with a wireless power transmission system. The wireless power transmitter is disposed in the air blowing device and wirelessly transmits power to the wireless power receiver in the flow switching device, eliminating the mechanical constraints of cables and enabling 360-degree rotation without twisting limitations.
2Reliability
If the flow switching device is restricted in rotation to prevent cable damage, then cable reliability is maintained, but purified air cannot be smoothly provided to all spaces
Solution Approach 1:
The patent eliminates the mechanical cable connection by implementing wireless power transmission. This allows the flow switching device to rotate freely 360 degrees to distribute purified air to various spaces, while the wireless power system maintains reliable power supply without the physical constraints of cables.
3Adaptability or versatility
If wireless power transmission is implemented to enable 360-degree rotation, then air distribution coverage is improved, but power connection complexity increases
Solution Approach 1:
The patent integrates wireless power transmission functionality into the existing air blowing device and flow switching device. The wireless power transmitter utilizes the existing power supply and transmitting coil structure, while the flow switching device incorporates a wireless power receiver that works with its existing motor and flow control mechanisms, achieving multi-functionality without excessive complexity.
