Segmented Dust Suction Housing to Protect Resilient Inlet Members
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dust suction devices face issues with malfunction due to dust accumulation on resiliently operating members, leading to impaired performance and reduced effectiveness in removing impurities from shoe bottoms, and they require frequent maintenance to prevent mold growth and bacterial breeding.
Innovation Solution
The design incorporates a housing with independently divided spaces for dust collection and elastic member operation, featuring a top plate with inlets, a separation plate, and resiliently operating members that open and close under pressure, along with a suction machine for efficient dust removal, and an optional controller for timed operation based on visitor detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If dust suction devices use resiliently operating members to open and close inlets, then dust and impurities can be removed from shoe bottoms, but dust accumulates on the resiliently operating members causing malfunction
Solution Approach 1:
The housing is divided into a first space for dust collection and a second space for housing the resiliently operating members, with a partition wall separating them. This segmentation prevents dust from reaching the resiliently operating members while maintaining their dust removal function, resolving the contradiction between productivity and reliability.
2Ease of manufacture
If simple weave construction mats are used for dust adsorption, then manufacturing is easy and cost-effective, but absorbability is low and cleanliness cannot be maintained long
Solution Approach 1:
The mat uses a composite structure combining a base fabric layer with a dust adsorption layer containing dust adsorption particles. This composite material design maintains ease of manufacture while significantly improving dust adsorption effectiveness and maintaining cleanliness over time, resolving the contradiction between ease of manufacture and reliability.
3Productivity
If fabric mats are used to adsorb moisture and dust, then dust can be absorbed initially, but mold growth and bad smell occur after dust accumulation
Solution Approach 1:
The dust adsorption particles are designed to prevent mold and bacterial growth by creating an environment unfavorable for biological contamination. This allows the mat to maintain dust adsorption capability while preventing harmful factors like mold growth and bad smells, resolving the contradiction between productivity and harmful factors generated.
