Solution Overview
Problem
Rechargeable vacuum cleaners face challenges in aligning with charging stands, resulting in low charging efficiency due to the difficulty in aligning grooves with guide ribs, which hampers accurate positioning and efficient charging.
Innovation Solution
Incorporating a first magnetic member on the vacuum cleaner and a second magnetic member on the charging stand for magnetic attraction, along with a pivotable pedal and safety protection devices, to facilitate fast and accurate positioning and enhance charging efficiency, while also providing a blade for hair cutting around the brushroll.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a guide rib and groove alignment mechanism is used for charging stand positioning, then the charging connection can be established, but the alignment is difficult to achieve and positioning accuracy is low
Solution Approach 1:
The patent replaces the mechanical guide rib and groove alignment system with a magnetic positioning system. Magnetic members are embedded in both the charging stand and the vacuum cleaner body, creating automatic magnetic attraction that guides and secures the vacuum cleaner in the correct charging position without requiring manual alignment of mechanical features.
Solution Approach 2:
The magnetic positioning system enables self-alignment and self-positioning of the vacuum cleaner on the charging stand. The magnetic attraction force automatically draws the vacuum cleaner into the correct position, eliminating the need for user intervention in the alignment process and ensuring consistent positioning accuracy.
2Productivity
If manual positioning alignment is required for charging, then the charging stand structure can be simple, but the charging efficiency is low due to time-consuming alignment
Solution Approach 1:
The magnetic positioning system replaces time-consuming manual alignment operations with automatic magnetic attraction. When the vacuum cleaner is placed near the charging stand, the magnetic members create an attractive force that quickly pulls the vacuum cleaner into the correct charging position, dramatically reducing the time required to establish charging connection.
Solution Approach 2:
The magnetic members are pre-positioned in both the charging stand and vacuum cleaner body during manufacturing. This preliminary positioning ensures that when the vacuum cleaner approaches the charging stand, the magnetic attraction immediately guides it to the correct position without requiring any adjustment or alignment actions by the user during the charging process.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The magnetic attraction ensures precise alignment and efficient charging, while the pivotable pedal and safety protection devices enhance user safety and convenience, and the blade expands the functionality of the charging stand by automatically cutting off hairs, improving overall charging efficiency and user experience.
Implementation Method 1
the first magnetic member is configured to cooperate with the second magnetic member through magnetic attraction so as to position the rechargeable vacuum cleaner to the charging stand
