Appliance Base Soft-Mount Structure for Shock and Friction Damping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing kitchen appliance bases fail to effectively dampen movements and shocks, leading to potential damage and instability during use, particularly when subjected to weight loads and friction.
Innovation Solution
A base design featuring a soft part that surrounds the extension, providing lateral and vertical cushioning without direct tensile load on the soft tissue, and a hard part clamped by the soft part for secure assembly, with the soft part being designed in multiple parts and made of flexible foam materials for enhanced damping properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the extension is accommodated in the shell part so that it can move transversely to a compression movement, then the device can absorb shocks and vibrations, but the extension directly contacts with hard shell parts causing friction and potential damage
Solution Approach 1:
The patent introduces a soft part as an intermediary element between the extension and the hard shell parts. This soft part completely surrounds the extension in the shell part, creating a cushioning layer that prevents direct contact between the extension and hard surfaces. The soft part absorbs friction and shock, eliminating damage while maintaining the transverse movement capability for vibration absorption.
Solution Approach 2:
The patent employs a flexible soft part that completely surrounds the extension within the shell part. This flexible element allows the extension to move transversely to compression movements while providing continuous protective contact. The soft part deforms elastically to accommodate extension movement, preventing rigid contact and friction damage between hard components.
2Device complexity
If the soft part only provides vertical cushioning without lateral extension, then the assembly is simpler, but the extension cannot be effectively cushioned in directions transverse to the weight force
Solution Approach 1:
The patent extends the soft part's functionality from purely vertical cushioning to multi-dimensional protection by having it completely surround the extension laterally within the shell part. This lateral extension of the soft part into the shell part creates protection in directions transverse to the weight force, while the soft part's elastic properties maintain assembly simplicity. The soft part forms a continuous cushioning envelope around the extension.
3Reliability
If the extension extends further down below the impingement surface without weight loading, then it provides additional engagement area, but it creates unnecessary complexity and potential friction points
Solution Approach 1:
The patent removes the unnecessary extension geometry below the impingement surface. By analyzing the actual functional requirements, the invention determines that the extension only needs to reach the impingement surface on the soft part to achieve adequate engagement. The soft part's lateral surround within the shell part provides additional contact area without requiring the extension to extend further down, thereby eliminating geometric complexity and potential friction points.
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 absorbs and distributes weight forces, reducing shock and movement-related stress, enhancing the stability and durability of the appliance by preventing damage from friction and ensuring secure attachment without additional assembly measures.
Implementation Method 1
the soft part in an upwards open shell section of the standing part is included... The same part of the extension can be cushioned by the soft tissue in the said area laterally to a direction of action of the weight and vertically in the direction of the weight
Implementation Method 2
The extension can move in the said area relative to the soft tissue, also relative to the area of the soft tissue extending laterally to the extension, above the loading surface. The extension is not connected to the soft tissue in the mentioned area, so that a movement in a direction transverse to the deflection movement due to the weight force can lead to a compression of the area of the soft tissue extending laterally to the extension

AI summary
The invention relates to a base (6) for an appliance, in particular a table-top food processor (1), the appliance having a housing (5) with an extension (9) which protrudes downwards in normal installation and which has a base (10) on a forming standing part (12) with the interposition of a soft part (25), the soft part (25) being accommodated in a shell section (18) of the standing part (12) which is open at the top and the extension reaching into the shell part also being transverse to a compression movement by a Weight of the device is movably accommodated in the shell part, with the soft tissue also forming an upper loading surface (27) for the extension (9). In order to achieve a better stability of the device during movement, it is proposed that the soft part (25), starting from the impingement surface, also be formed laterally to the extension (9) at the top, even without weight load from the extension (9).
