Personalised air purification device with a blow-off part
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air purification systems in open-plan offices and living spaces fail to provide personalized and hygienic air flow, as they often require restrictive devices that limit user mobility and can contaminate the air due to hose-based designs and inadequate handling, lacking direct air stream direction without hoses and easy connection to air cleaning devices.
Innovation Solution
A personalized air purification device with a blow-out part directly connected to the housing via releasable fastenings like plug-in or magnetic holders, allowing for easy attachment and detachment to direct air flow against the body, featuring a disc-shaped design with integrated filters and optical indicators for airflow control, ensuring improved hygiene and user convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hose-based air supply system is used to deliver cleaned air to the user, then the air can be supplied from a centralized location, but the hose can accumulate dirt and bacteria that contaminate the supplied air and the hose restricts user mobility
Solution Approach 1:
The patent removes the hose component from the air supply system entirely. The air cleaner is designed with a blow-out part that attaches directly to the user's clothing or body, eliminating the intermediate hose that accumulates contaminants and restricts movement. This extraction of the problematic hose element resolves both the contamination and mobility issues.
Solution Approach 2:
The patent introduces a blow-out part as a new intermediary component that attaches directly to the user. This mediator eliminates the need for a long hose by providing a direct connection point on the user's body, thereby preventing contamination accumulation and unrestricted user movement while maintaining the air supply function.
2Reliability
If a centralized air cleaner with a long hose is used, then air can be cleaned and delivered to the user, but the device placement on the floor and hose connection creates difficult handling and noise
Solution Approach 1:
The patent segments the air supply system into two independent components: a compact air cleaner unit and a separate blow-out part that attaches to the user. This segmentation allows the air cleaner to be placed conveniently while eliminating the noisy and cumbersome long hose, improving handling ease without compromising air cleaning functionality.
Solution Approach 2:
The patent transitions from a floor-based centralized air cleaner with horizontal hose extension to a portable unit with vertical attachment to the user's body. This dimensional change from floor placement to body-mounted delivery point eliminates handling difficulties and reduces noise by shortening the air path.
3Adaptability or versatility
If a blow-out part is provided that can be detached and attached to direct air flow against the body, then personalized air delivery is achieved, but the fastening mechanism adds device complexity
Solution Approach 1:
The patent replaces complex mechanical fastening systems with simpler attachment mechanisms such as magnetic holders or lightweight snap-fit connections. This substitution maintains the adaptability of directing air flow to different body locations while significantly reducing the complexity of the fastening mechanism.
Solution Approach 2:
The patent employs simple releasable fastenings that change the attachment parameter from permanent to temporary, allowing easy attachment and detachment of the blow-out part. This parameter change enables personalized air delivery positioning without requiring complex fastening mechanisms, maintaining versatility while minimizing complexity.
