Solution Overview
Problem
Conventional humidification and air cleaning devices face challenges in effectively recognizing user voice commands due to operating noise and moisture interference, which affect the performance of voice recognition modules.
Innovation Solution
The proposed solution involves a humidification and air cleaning apparatus design that includes a leg wall and plurality of legs forming a concave space, with the input assembly, housing a microphone, disposed in front of this concave space to minimize noise and moisture interference. This configuration allows for effective voice signal reflection and reduction of operating noise impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the input assembly is exposed to the outside for effective voice recognition, then voice recognition capability is improved, but the device is more susceptible to operating noise and moisture interference
Solution Approach 1:
The housing is divided into multiple segments including the leg wall and legs that form a concave space structure. This segmentation allows the input assembly to be positioned in a protected niche while maintaining exposure to external voice commands, effectively separating the voice reception function from the noise-prone operational areas.
Solution Approach 2:
The concave space formed by the leg wall and legs acts as an intermediary structure between the external environment and the input assembly. This intermediate space reflects voice signals toward the input assembly while shielding it from direct exposure to operating noise and moisture, mediating between the need for exposure and protection.
2Object-affected harmful factors
If the input assembly is positioned far from noise-generating components, then operating noise interference is minimized, but voice signal reception may be weakened
Solution Approach 1:
The concave space created by the leg wall and legs forms a curved, bowl-like structure that acoustically focuses and reflects voice signals toward the input assembly. This curvature allows the input assembly to be positioned farther from noise sources while maintaining strong voice signal reception through acoustic reflection and focusing effects.
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

AI summary
The present disclosure comprises a lower base, a lower housing, a plurality of legs, a leg wall, and an input assembly. The lower base is supported by the ground. The lower housing is spaced apart upwardly from the lower base and forms a suction gap by being spaced apart from the lower base. The plurality of legs are disposed on at least one of the lower base and the lower housing. The plurality of legs supports the lower housing. The leg wall connects two legs adjacent to each other. The input assembly is disposed at the lower housing. The input assembly protrudes toward the suction gap. The input assembly receives a wireless signal. The plurality of legs include a first leg and a second leg adjacent to each other. The input assembly is disposed outside the leg wall. In the present disclosure, since an input assembly receiving a voice signal is exposed to the outside, a user's voice may be effectively recognized. In the present disclosure, since the leg wall is disposed between the input assembly and the lower housing inlet, it is possible to suppress the propagation of the operating noise generated from the blowing unit to the input assembly.
