Food Processor Enclosure Segmentation to Reduce Noise and Vibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Food processors generate noise and vibrations due to the collision of the processing member with the container and its inner walls, leading to increased risk of conduction and degradation of the binding force between the container and base, and require large enclosures that occupy excessive space.
Innovation Solution
A food processor design featuring a base, container with a handle support, and enclosures that support the handle to suppress container shaking and noise, using elastic sealing members and a vacuum exhaust system to create an air-tight space around the container, reducing vibrations and noise transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If an enclosure entirely covers the container to shield noise, then noise shielding is improved, but the device occupies excessive space and requires a larger base
Solution Approach 1:
The enclosure is divided into an upper enclosure and a lower enclosure that can be separately positioned and coupled. The lower enclosure is installed on the base to surround the lower portion of the container, while the upper enclosure is positioned to surround the upper portion, allowing noise shielding without requiring a single large enclosing structure that would occupy excessive space.
Solution Approach 2:
The enclosures are designed to extend in specific directions (laterally and vertically) rather than requiring a large horizontal footprint. The lower enclosure extends laterally from the base, and the upper enclosure extends vertically, allowing effective noise shielding within a compact overall volume.
2Ease of operation
If the container is detachably coupled to the base, then ease of operation is improved, but the height of the food processor increases and vibration transmission risk increases
Solution Approach 1:
The lower enclosure acts as an intermediary structure between the base and the container. It is installed on the base and provides lateral extension that stabilizes the container during operation, reducing vibration transmission while maintaining the detachable coupling for ease of operation.
3Object-affected harmful factors
If enclosures are designed to surround the container, then noise shielding is improved, but the binding force between container and base degrades due to increased vibration conduction
Solution Approach 1:
The enclosure system is segmented into upper and lower portions that are positioned at different heights. The lower enclosure is installed on the base and provides stabilization, while the upper enclosure is positioned to surround the upper portion of the container. This segmentation allows noise shielding without creating a rigid structure that would transmit vibrations and degrade binding force.
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
Effectively shields noise and suppresses container shaking during operation, reducing the risk of conduction and maintaining a secure binding force while minimizing the occupied space compared to traditional designs.
Implementation Method 1
The upper support surface, the first side support surface, and the second side support surface may be configured as sealing members having an elastic force.

AI summary
A food processor may include: a base; a container including an accommodation tub installed on an upper surface of the base and accommodating a processing target, a handle support part laterally protruding from a side surface of the accommodation tub, and a handle extending upwards or downwards from the handle support part; a lower enclosure installed on the upper surface of the base to surround a lower portion of the accommodation tub; and an upper enclosure positioned in a coupled state and a released state with respect to the lower enclosure and cooperatively supporting the handle support part together with the lower enclosure to suppress shaking of the container.
