Kitchen Appliance Stand Structure for Vibration Damping Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stands for food processors fail to effectively dampen movements and vibrations, particularly during dough preparation, leading to jerky movements and potential displacement on the support surface.
Innovation Solution
A base design featuring a soft part, such as polyurethane foam, accommodated within a shell section with a movable extension that allows horizontal movement, providing elastic deformation and restoring forces to maintain stability and prevent displacement, while the standing part is harder and connected via a form-fitting mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the base is designed as a soft part overall, then vibration damping is improved, but the device becomes less stable under heavy loads
Solution Approach 1:
The base is designed with different hardness zones: a softer inner region for vibration damping and a harder outer region for stability. This local differentiation allows the base to simultaneously absorb vibrations effectively while maintaining structural stability under heavy loads, resolving the contradiction between softness and stability.
Solution Approach 2:
The base combines materials with different hardness properties in a composite structure. The softer material provides vibration damping while the harder material provides structural support and stability, allowing both contradictory requirements to be satisfied through material composition rather than uniform material selection.
2Strength
If the extension is rigidly connected to the standing part, then structural strength is improved, but movement damping capability is reduced
Solution Approach 1:
The connection between the extension and standing part is designed to be dynamically adaptable rather than rigidly fixed. The base structure allows controlled relative movement while maintaining structural integrity, enabling it to absorb shocks and dampen movements while preserving necessary structural strength for supporting the device.
3Force
If the soft part is made harder, then load-bearing capacity is improved, but vibration damping effectiveness is reduced
Solution Approach 1:
Different regions of the base are assigned different hardness levels according to their specific functional requirements. The load-bearing regions use harder materials to support weight, while the vibration-absorbing regions use softer materials to dampen oscillations, thus simultaneously achieving both load-bearing capacity and vibration damping effectiveness.
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
The design effectively dampens horizontal and vertical movements, ensuring the food processor remains stable and immobile on the surface, even under high resistance and torque, by converting energy into friction and restoring forces, thus preventing jerky movements and displacement.
Implementation Method 1
an elastic deformation of the soft tissue in this horizontal direction can occur with a corresponding horizontal movement
Implementation Method 2
converting energy into friction and restoring forces, thus preventing jerky movements and displacement

AI summary
The stand (6) has a housing (5) comprising a support projection part (9) forming on a base, and a condition part (11) seated by a flexible element. The flexible element is accommodated in an open-topped shell portion of the condition part. The projection part extends into a side cover of the shell portion. The condition part is cooperated with the projection for enabling a lose-safe support with the projection in a force-fit manner. The projection part is held horizontally and vertically and movably received in the shell portion under a vertical coverage to the shell portion.
