Solution Overview

Problem

Existing baseboards in industrial settings, particularly in the food industry, face issues with ineffective sealing due to irregularities in walls and floors, retention areas that promote microorganism growth, and aesthetically unpleasing designs with grooves that complicate cleaning and hygiene.

Innovation Solution

A device featuring a one-piece hard profile with inclined flexible lips, elastically deformable foam strips for fixing and sealing, and a connector system with a clip-on cover element, designed to absorb shocks and irregularities while ensuring tight sealing and easy maintenance, eliminating retention zones and grooves.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If conventional baseboards with hollow zones and removable covers are used, then the baseboards provide shock resistance and structural protection, but they create retention areas that promote microorganism growth and deteriorate hygiene

Engineering Contradiction:
Improveshock resistanceVSAvoidmicroorganism growth
Core Design Contradiction:
StrengthVSObject-affected harmful factors

Solution Approach 1:

The invention extracts and eliminates the hollow zone and removable cover from the baseboard structure. The profile is designed as a solid one-piece element without internal cavities, thereby removing the retention areas where water and microorganisms could accumulate, while preserving the external protective function

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention uses foam strips with closed-cell structure for fixing and sealing. These foam materials provide shock absorption and irregularity compensation through their cellular structure, while the closed cells prevent water penetration and microorganism growth, resolving the contradiction between mechanical cushioning and hygiene

Inventive Principle:
Principle #31Porous materials

2Ease of manufacture

If baseboards have grooves and removable covers for fixing mechanisms, then they provide structural attachment capability, but they create additional retention areas that are difficult to clean and compromise aesthetics

Engineering Contradiction:
Improvefixing mechanism integrationVSAvoidcleanability
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The invention merges the fixing mechanism directly into the solid profile structure. Foam strips with adhesive are integrated into the profile design, eliminating the need for separate hollow zones and removable covers. This integration maintains attachment functionality while creating a smooth, continuous surface that is easy to clean and aesthetically pleasing

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The invention removes grooves and separate cover elements from the baseboard design. The fixing system is implemented through foam strips applied to the solid profile, eliminating crevices and discrete components that would create retention areas and complicate cleaning

Inventive Principle:
Principle #2Taking out (Extraction)

3Strength

If rigid fixing methods are used to secure baseboards to walls, then strong mechanical attachment is achieved, but the baseboards cannot adapt to wall irregularities and are susceptible to shock damage

Engineering Contradiction:
Improveattachment strengthVSAvoidirregularity absorption
Core Design Contradiction:
StrengthVSAdaptability or versatility

Solution Approach 1:

The invention changes the mechanical parameters of the fixing system by using foam strips with viscoelastic properties. These foam elements can deform and adapt to wall irregularities while maintaining strong attachment through adhesive bonding, providing both flexibility for adaptation and strength for secure fixation

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The invention uses composite fixing elements combining foam material with adhesive. The foam provides shock absorption and adaptability to irregularities, while the adhesive ensures strong mechanical attachment to the wall, creating a hybrid fixing system that achieves both flexibility and strength

Inventive Principle:
Principle #40Composite materials

4Object-affected harmful factors

If smooth front faces without sharp corners are used, then hygiene is improved by eliminating retention areas, but manufacturing complexity increases

Engineering Contradiction:
Improvemicroorganism growth preventionVSAvoidprofile manufacturing
Core Design Contradiction:
Object-affected harmful factorsVSEase of manufacture

Solution Approach 1:

The invention applies curved transitions and rounded edges to the profile geometry, eliminating sharp corners that create retention areas. The smooth, continuous curved surfaces prevent water and microorganism accumulation while being compatible with standard extrusion manufacturing processes for plastic profiles

Inventive Principle:
Principle #14Spheroidality (Curvature)
