Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing methods for deodorizing and perfuming environments require specialized devices, which are costly, environmentally unfriendly, and necessitate separate disposal, and do not allow for direct integration of deodorant and perfume substances into core materials.

Innovation Solution

A core for rolls is designed with integrated absorbent materials that can be wrapped around a tubular segment, allowing for the direct release of deodorant and perfume substances into the environment without the need for additional devices, using cardboard strips and additional absorbent strips or materials soaked with substances, which can be activated as needed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If specialized deodorizing devices are used, then deodorizing and perfuming action is achieved, but cost increases and device complexity increases

Engineering Contradiction:

Improvedeodorizing actionVSAvoiddevice complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the deodorizing function with the roll core structure by integrating absorbent material directly into the core. The core includes an axial cavity filled with absorbent material that releases deodorant substances, merging the structural support function with the deodorizing function into a single integrated component, thereby eliminating the need for separate deodorizing devices

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The roll core is designed to perform multiple functions simultaneously: it provides structural support for the wrapped material, acts as a deodorizing device through the absorbent material in its axial cavity, and serves as a perfume dispenser. This multi-functionality eliminates the need for separate specialized devices

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If specialized containers and supports are used for deodorant substances, then deodorizing action is achieved, but cost increases

Engineering Contradiction:

Improvedeodorizing actionVSAvoidmanufacturing cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent merges the deodorizing function with the roll core structure by integrating absorbent material directly into the core. The core includes an axial cavity filled with absorbent material that releases deodorant substances, merging the structural support function with the deodorizing function into a single integrated component, thereby eliminating the need for separate deodorizing devices

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The roll core serves itself by incorporating the deodorizing function directly into its structure. The absorbent material within the axial cavity automatically releases deodorant substances without requiring external containers or supports, making the system self-sufficient and reducing manufacturing costs

Inventive Principle:

Principle #25Self-service

3Reliability

If traditional deodorant devices are used, then deodorizing action is achieved, but environmental friendliness worsens due to disposal requirements

Engineering Contradiction:

Improvedeodorizing actionVSAvoidenvironmental impact

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The roll core with integrated absorbent material is designed as a disposable component that is discarded with the used rolls. This eliminates the need for separate disposal of deodorant containers and supports, simplifying waste management and reducing environmental impact through single-stream disposal

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

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

Enables effective and cost-efficient deodorizing and perfuming without specialized equipment, with environmentally friendly disposal and reduced material waste, as the core itself serves as a substance dispenser.

Implementation Method 1

suitable containers can be used which internally preserve the substances in the liquid or gelatinous state

Methodology Applied

Scientific EffectAbsorption: Absorption (physical)

Implementation Method 2

through which the substances spread slowly and over a substantially extended length of time

Methodology Applied

Scientific EffectEvaporation: Evaporation

Implementation Method 3

deodorant and perfume substances are spread into the environments

Methodology Applied

Scientific EffectDiffusion: Diffusion
