Charging Stand Support Structure for Moisture Evaporation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric apparatus units, such as those for electric toothbrushes, face issues with moisture evaporation, leading to potential corrosion and adverse sanitary conditions due to water residue when the devices are charged.
Innovation Solution
The electric apparatus unit incorporates a charging stand with a support structure that allows the electric apparatus to be positioned in a way that moisture can easily evaporate, featuring a power transmission coil and magnetism collection coil configuration that maintains non-contact power transmission while facilitating air circulation beneath the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electric toothbrush is set on the installation base through a space surrounded by an arm of a charging stand, then non-contact power transmission is achieved, but moisture between the bottom surface of the electric toothbrush and the installation base hardly evaporates
Solution Approach 1:
The support arm is designed with a through-hole structure that allows moisture to escape from the bottom surface of the electric toothbrush. By creating a vertical dimension for moisture evacuation through the through-hole, the patent resolves the contradiction between maintaining stable power transmission contact and enabling moisture evaporation.
Solution Approach 2:
The support arm incorporates a through-hole that functions as a porous structure, allowing moisture to pass through. This porous design enables moisture to be discharged from the contact area between the electric toothbrush and installation base, preventing moisture accumulation while maintaining structural integrity for power transmission.
2Stability of the object's composition
If the electric toothbrush is supported on the installation base, then stable positioning is achieved, but moisture evaporation is hindered
Solution Approach 1:
The support arm is segmented into multiple functional zones: a contact portion for stable positioning, a through-hole portion for moisture evaporation, and a connection portion for structural support. This segmentation allows each zone to perform its specific function independently, achieving both stable positioning and effective moisture removal.
Solution Approach 2:
The through-hole in the support arm acts as an intermediary structure that facilitates moisture evaporation without interfering with the stable contact between the electric toothbrush and installation base. It provides a dedicated pathway for moisture to escape while the surrounding structure maintains positioning stability.
