Multi-Orientation Air Purifier with Low Center of Gravity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air purifiers are limited to a single operating orientation, restricting user placement and often tip over due to an unstable center of gravity, especially in vertical positions.
Innovation Solution
An air purifier design that allows for both vertical and horizontal orientations, featuring a housing with a removable base and sides for support, a motor strategically located between the midpoint and bottom to maintain stability, and a cover with a light source for aesthetic purposes, ensuring the device remains upright and functional in various settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the air purifier is designed to operate in multiple orientations, then the adaptability of the device is improved, but the stability of the device deteriorates
Solution Approach 1:
The air purifier incorporates a movable base that can be positioned at different locations along the housing, allowing the device to adapt to various orientations (vertical, horizontal, angled) while maintaining stability through dynamic repositioning of the support point
Solution Approach 2:
The center of gravity of the air purifier is designed to be lower than its geometric center, creating a stable equilibrium position. This parameter change in the weight distribution allows the device to remain stable across multiple orientations by ensuring the center of gravity remains within the support base
2Reliability
If the motor is located to maintain stability in vertical orientation, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The motor is specifically positioned in the lower half of the housing, creating an asymmetric weight distribution that lowers the center of gravity. This localized placement of the heavy motor component achieves stability without requiring complex additional mechanisms
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables flexible placement and reduced risk of tipping, enhancing user convenience and safety by maintaining airflow efficiency and stability across different orientations.
Implementation Method 1
a motor is also located within the housing. The motor includes a motor shaft and a fan is on the motor shaft for urging air into the air inlet, through the airflow path and out of the air outlet
Implementation Method 2
The air purifier is positionable in one of a vertical operating orientation when the weight of the housing is supported by the base and a horizontal operating orientation when the weight of the housing is supported by one of the sides of the housing
