Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional containers with adhered protective mats cannot be effectively cleaned in hot water or dishwashers, as the adhesive degrades, and the mats often contain toxic materials, limiting their usability and cleaning efficiency.

Innovation Solution

A removably attachable base assembly with a resilient portion, such as a cushion pad made from materials like silicone or rubber, which provides vibration isolation, anti-skid properties, and can be cleaned separately from the container, featuring a mechanical fit with the container's recess to allow for easy assembly and disassembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a protective mat is adhered to the container bottom using adhesive, then the container gains vibration isolation and anti-skid properties, but the adhesive degrades in hot water or dishwashers and may contain toxic materials

Engineering Contradiction:

Improvevibration isolation and anti-skid functionalityVSAvoidtoxic materials and adhesive degradation

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The protective mat is separated from the container as a distinct, removable base assembly that can be independently cleaned and replaced. This segmentation eliminates the need for adhesive bonding while maintaining the protective functions, allowing the mat to be washed separately in hot water or dishwashers without degrading the container or releasing toxins.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A mechanical interface (recess and base assembly structure) serves as an intermediary between the container and protective mat, replacing the chemical adhesive bond with a physical fit. This mechanical connection maintains the protective mat's position and functionality while eliminating adhesive-related harmful effects.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If a protective mat is adhered to the container bottom, then the container gains surface protection, but the container cannot be effectively cleaned in hot water or dishwashers

Engineering Contradiction:

Improvesurface protectionVSAvoidcleaning efficiency

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

By dividing the container system into a removable base assembly and the main container body, the protective mat becomes accessible for separate cleaning. The base assembly can be removed and washed independently in hot water or dishwashers, while the container can also be cleaned thoroughly, eliminating the cleaning limitations imposed by adhered mats.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The base assembly transitions from a static adhered state to a dynamic removable state, allowing it to be easily detached for cleaning and reattached when needed. This dynamic design enables flexible cleaning operations without compromising the protective surface function.

Inventive Principle:

Principle #15Dynamics

3Stability of the object's composition

If adhesive is used to attach the protective mat, then the mat remains fixed to the container, but the adhesive degrades under high temperature and moisture conditions

Engineering Contradiction:

Improvemat attachment stabilityVSAvoidresistance to hot water and dishwasher temperatures

Core Design Contradiction:

Stability of the object's compositionVSTemperature

Solution Approach 1:

The chemical adhesive bonding system is replaced with a mechanical attachment system consisting of a recess in the container bottom and a corresponding base assembly structure. This mechanical interface provides stable attachment that is resistant to high temperatures and moisture, eliminating the degradation issues associated with adhesive materials in dishwasher conditions.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A container has a removable base assembly. The base assembly has a resilient portion. The base assembly is removably attachable to the container in a recess of the container. The base assembly being dimensioned to have a fixed fit with the recess such that when the base assembly is assembled with the container, the resilient portion is exposed from the recess allowing the container to be supported on a support surface by the resilient portion of the base assembly.
