Solution Overview
Problem
Existing cleaning devices are prone to water accumulation and electrical failures due to seams allowing liquids to enter, which can lead to dampness and shorten the device's service life, potentially causing electrical safety accidents.
Innovation Solution
A cleaning device design featuring a main body with a first accommodating chamber and a first electronic assembly, where a first flow drainage channel is formed around the top of the chamber to discharge liquids outside, reducing the likelihood of liquid entering the chamber and protecting the electronic assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If cleaning devices are designed with seams for assembly and manufacturing, then ease of manufacture is improved, but liquid ingress through seams causes water accumulation and electronic component failure
Solution Approach 1:
The patent extracts the harmful function of seams by introducing a waterproof layer that completely covers seam areas, effectively removing the liquid ingress pathway while preserving the segmented structure for ease of manufacture. The waterproof layer is applied to the inner surface of the housing, specifically covering the seam regions where liquid would otherwise penetrate.
Solution Approach 2:
The waterproof layer serves as an intermediary element between the housing segments. It is positioned at the seam interfaces and acts as a mediator that prevents liquid from penetrating through the assembly gaps, allowing the housing to maintain its segmented construction for manufacturing convenience while achieving waterproof integrity.
2Reliability
If waterproof measures are added to prevent liquid ingress, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent employs a flexible waterproof layer in the form of a thin film that conforms to the inner surface of the housing. This thin film structure provides effective waterproofing without adding significant structural complexity or bulk to the device. The waterproof layer can be made of materials like rubber or plastic that are easily integrated into existing housing designs.
3Object-generated harmful factors
If drainage channels are added to discharge liquid, then water accumulation is reduced, but manufacturing precision requirements increase
Solution Approach 1:
The drainage system is segmented into multiple components: drainage holes positioned at the bottom of the housing, a waterproof layer with integrated drainage pathways, and a waterproof stopper mechanism. This segmentation allows each component to be manufactured separately with standard precision, and they work together to achieve effective liquid drainage without requiring ultra-precise manufacturing of the entire assembly.
