Solution Overview
Problem
Existing solutions for improving indoor environments, such as sound dampening and air quality, often require separate devices that can be bulky, costly, and complex, and fail to effectively combine sound dampening with air purification in a cost-effective and efficient manner.
Innovation Solution
A sound dampening device with a frame, rear, and front layers forming an enclosed space, incorporating a first sound absorbing layer and an air purifying device in fluid communication, where purified air is discharged through a distribution layer with low flow resistance, achieving both sound dampening and localized air purification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate air purifiers are used to improve air quality, then air purification function is achieved, but the device becomes visually disturbing, causes unpleasant air flows, draught, high noise levels and occupies space
Solution Approach 1:
The patent combines the air purifying device with the sound dampening device into a single integrated unit. The air purifier is positioned inside the sound dampening device, sharing the same housing and structure. This merging eliminates the need for separate air purifier equipment, thereby removing the associated visual disturbance, unwanted air flows, and additional noise sources while maintaining effective air purification in the local environment.
2Reliability
If common air purifiers are used to purify large air volumes, then air quality in the whole room is improved, but the device becomes large and bulky and requires powerful fans with high power consumption
Solution Approach 1:
The invention shifts from a global air purification approach to a local one. The air purifying device is designed to purify only the air in the immediate local environment around the user rather than the entire room. This localized approach significantly reduces the air volume that needs to be processed, allowing for a compact device design with smaller dimensions and lower power consumption while still effectively improving air quality where it is most needed.
3Object-affected harmful factors
If sound absorbing materials are used to improve acoustic properties, then sound dampening is achieved, but ventilation is hindered and dust, particles and microorganisms are collected
Solution Approach 1:
The sound dampening device is segmented into multiple functional layers including sound absorbing materials, ventilation channels, and filtration elements. The ventilation channels are specifically designed to allow air flow through the device structure, preventing the sound absorbing materials from completely blocking ventilation. Simultaneously, filtration elements are integrated to capture dust, particles, and microorganisms from the air passing through, thus resolving the contradiction between sound dampening and ventilation while adding air purification functionality.

Function Achieved in This Case
The device provides efficient sound dampening and localized air purification with reduced noise and power consumption, creating a comfortable indoor environment while minimizing space and cost.
Implementation Method 1
Both the sound absorbing layer and the cavity dampen sounds from the environment as well as from the air purifying device
Implementation Method 2
By arranging an air purifying device in fluid communication with the cavity, such that purified air from the air purifying device is supplied to the cavity via an inlet and is discharged through at least one opening in the first sound absorbing layer and at least one output zone in the front layer
