Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional perfume diffusers are expensive, generate waste, and require a power supply, making them costly and environmentally unfriendly, while also being difficult to use effectively in terms of fragrance control.
Innovation Solution
A free-standing, eco-friendly perfume diffuser made from plant polymers like cardboard, featuring a modular design with adjustable fragrance release, utilizing a coaxial cylindrical structure that can switch between closed and open configurations to control perfume diffusion, and can be attached to various surfaces using aeration holes and adhesive options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional plastic perfume diffusers with electrical power supply are used, then fragrance diffusion can be achieved, but the device becomes expensive and generates waste
Solution Approach 1:
The patent changes the material parameter from conventional plastic to plant polymer/cardboard, transforming the device into an eco-friendly, biodegradable alternative that maintains fragrance diffusion functionality while eliminating environmental pollution issues
Solution Approach 2:
The patent employs a disposable cardboard-based diffuser design that is cheap to produce and dispose, replacing expensive conventional diffusers. The device is intended for single-use or limited use cycles, after which it can be discarded without environmental harm due to its biodegradable material composition
2Productivity
If electrical heating or spray mechanisms are used for perfume diffusion, then fragrance release is effective, but the device requires power supply and becomes complex
Solution Approach 1:
The patent implements a self-service fragrance diffusion mechanism where the perfume bottle itself serves as the diffusion medium. The liquid perfume naturally contacts the cardboard walls through capillary action, eliminating the need for external power supplies, heating elements, or spray mechanisms
Solution Approach 2:
The patent replaces complex mechanical or electrical diffusion systems (heating elements, pumps, spray mechanisms) with a simple passive diffusion system based on capillary action and natural evaporation, dramatically simplifying the device structure
3Reliability
If fixed fragrance diffusion is used in conventional devices, then diffusion occurs, but the amount of perfume released cannot be easily adjusted
Solution Approach 1:
The patent introduces a dynamic, adjustable diffusion system where users can control the fragrance release rate by adjusting the immersion depth of the cardboard cylinder in the perfume bottle. This allows real-time modification of the diffusion intensity according to user preferences
Solution Approach 2:
The patent segments the diffusion process into adjustable portions by allowing the cardboard cylinder to be inserted to different depths in the perfume bottle. This segmentation enables independent control of the active diffusion surface area, providing ease of operation
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 solution provides a cost-effective, waste-free, and user-friendly fragrance diffusion system that allows for adjustable perfume release without a power supply, enhancing environmental sustainability and user control over fragrance distribution.
Implementation Method 1
The device consists of a cardboard cylinder inserted into a liquid perfume bottle, allowing the liquid to diffuse through the porous structure
Implementation Method 2
progressive release of scents and fragrances into the environment

AI summary
A free-standing device for releasing fragrances includes a hollow external cylinder having an inner surface engaging the outer surface of an internal cylinder, the internal cylinder being closed. The inner surface of the external cylinder and the outer surface of the internal cylinder are fully at contact with each other. If open, the internal cylinder projects beneath the external cylinder, allowing the user to insert it into a support having a resting surface and an upper projection perforated centrally. The upper projection has aeration holes, sliding the internal cylinder with respect to the external cylinder exposing a portion of the inner surface of the external cylinder and the outer surface of the internal cylinder. A perfumed scent is applied on the inner surface of the external cylinder and/or on the outer surface of the internal cylinder; the internal cylinder having break-lines for removing portions of the internal cylinder.
