Blender Noise Blocking Enclosure with External Handle Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional blenders generate significant noise due to the mechanism transferring drive force and food collisions, which obstructs conversation and disrupts environments, and existing noise-blocking enclosures are large, heavy, and inefficient in noise reduction.
Innovation Solution
A compact blender design with a noise-blocking device that includes a lower blocking wall connected to the body and an upper blocking wall that pivots to enclose the container, allowing the handle to extend outside, along with an exhaust device and sealing members to enhance noise isolation and user convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a typical blender enclosure is configured to receive both a container and handle, then the enclosure can accommodate all components, but the enclosure becomes large and requires a separate handle to open/close the cover
Solution Approach 1:
The handle is extracted from the enclosure structure and positioned externally. The enclosure no longer needs to accommodate the handle internally, allowing for a more compact design while maintaining the ability to open and close the cover through the externally positioned handle.
Solution Approach 2:
The enclosure is divided into distinct functional zones: the main body that accommodates the container, and the externally positioned handle for operation. This segmentation allows each component to be optimized independently for its specific function.
2Strength
If the cover constitutes a front part of the enclosure to be heavy, then the cover has structural strength, but the entire front part must be open allowing noise leakage
Solution Approach 1:
The enclosure design provides structural strength where needed (in the main body and cover connections) while maintaining noise blocking in other areas. The handle opening is a localized exception that provides user access without compromising overall noise isolation, as it is positioned and sized to minimize noise leakage.
3Device complexity
If the enclosure is made compact and simple, then the structure is improved, but noise blocking effectiveness may be reduced
Solution Approach 1:
By extracting the handle from the enclosed space and positioning it externally, the noise-blocking volume is maximized while maintaining operational functionality. This extraction allows the main enclosure to be compact and simple without sacrificing noise blocking effectiveness.

AI summary
Disclosed is a blender including a noise blocking device. The blender includes: a container receiving food therein and having a processing member in which a processing member for processing food accommodated in the container is rotatably mounted thereon; a handle connected to the container; a body configured to allow the container to be mounted on an upper side thereof and receiving a drive device for supplying drive force for rotation of the processing member; and a noise blocking device connected to the body to define a closed space for receiving the container, wherein the handle is disposed outside the noise blocking device. The blender has a compact and simple structure, and provides user convenience. The noise blocking device of the blender can have an improved noise blocking effect.
