Solution Overview

Problem

Existing air purification devices for vehicles are not securely fixed and are cumbersome to assemble, lacking mobility and the ability to be assigned to specific passengers, with limited adjustment of airflow direction and requiring complex attachment methods.

Innovation Solution

A disc-shaped air purification device with a rotatable housing mounted on an adapter plate, allowing 360-degree rotation for adjustable airflow direction, easy attachment to vehicle components, and a snap-in locking mechanism for secure and easy removal, along with a compact design for improved mobility and airflow control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the air purifier is securely fixed inside the vehicle to prevent it from being thrown around, then stability and safety are improved, but the device cannot be easily removed or reassigned to different passengers

Engineering Contradiction:
Improvesecurity of fixationVSAvoidease of removal and reassignment
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The device is divided into two separate components: an adapter plate that is securely fixed to the vehicle seat, and the air purifier unit that can be easily attached and detached from the adapter plate. This segmentation allows the base to remain fixed for stability while the air purifier can be easily reassigned to different passengers by simply detaching and reattaching to different adapter plates positioned at various seat locations.

Inventive Principle:
Principle #1Segmentation

2Reliability

If the air purifier is mounted using a screw connection to ensure secure fixation, then reliability is improved, but the mounting process becomes cumbersome and complex

Engineering Contradiction:
Improvesecurity of fixationVSAvoidease of mounting
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The traditional screw connection mechanical system is replaced with a simpler snap-in locking mechanism. The air purifier unit features locking protrusions that engage with corresponding recesses in the adapter plate, providing secure fixation without requiring tools or complex assembly procedures. This mechanical substitution maintains reliability while dramatically simplifying the mounting process.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If the air purifier housing is designed in a compact disc-shaped form factor, then mobility and adaptability are improved, but the internal space for filters and fan becomes limited

Engineering Contradiction:
Improvemobility and positioning flexibilityVSAvoidinternal housing volume
Core Design Contradiction:
Adaptability or versatilityVSVolume of stationary object

Solution Approach 1:

The compact disc-shaped housing utilizes three-dimensional space efficiently by arranging the fan wheel and filter elements in vertical and radial configurations within the limited volume. The filter elements are positioned around the fan assembly, maximizing the use of available space in this compact form factor while maintaining adequate filtration capacity and airflow paths.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
