Multi-Cartridge Candle for Simultaneous Fragrance Diffusion

Solution Overview

Problem

Existing candles capable of diffusing multiple fragrances cannot simultaneously release a plurality of volatile active substances, limiting user customization and efficiency in fragrance diffusion while maintaining low manufacturing costs and good burning properties.

Innovation Solution

A candle design featuring a base portion with multiple holes for cartridges, each carrying a different volatile active substance, allowing for simultaneous diffusion and user-selectable fragrance combinations, with wicks positioned to prevent flame overlap and enhance diffusion efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If candles are made with several successive layers each comprising a different type of perfume, then multiple fragrances can be included in the candle, but the fragrances are diffused in turn rather than simultaneously

Engineering Contradiction:

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The candle is segmented into multiple independent cartridges, each containing a different fragrance. These cartridges are positioned side-by-side in separate wells within the candle body, allowing each fragrance to be released independently and simultaneously through its own wick, rather than releasing fragrances sequentially through layered structures.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If users want to select and combine fragrances according to their desires, then customization is enabled, but device complexity increases

Engineering Contradiction:

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The candle system is divided into replaceable cartridge modules that users can insert and remove independently. Each cartridge is a self-contained unit with its own wick and fragrance reservoir, allowing users to mix and match different fragrance combinations without complicating the overall candle structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The candle body with its array of wells serves as a universal platform that can accommodate any combination of cartridges. The base candle structure remains simple and unchanged, while the interchangeable cartridges provide the customization functionality, separating the fixed infrastructure from the variable components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Productivity

If high loads of multiple fragrances are diffused simultaneously, then fragrance diffusion efficiency is improved, but manufacturing costs increase

Engineering Contradiction:

Core Design Contradiction:

ProductivityVSEase of manufacture

Solution Approach 1:

By segmenting the fragrance loads into separate cartridges rather than mixing multiple fragrances into a single homogeneous candle body, the system achieves high diffusion efficiency for each fragrance independently while using simple, cost-effective manufacturing processes for each cartridge unit.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system changes the physical state and distribution parameters of the fragrances by containing them in separate solid or semi-solid cartridge forms rather than dissolved in a common wax matrix. This allows for higher concentration loads of each fragrance to be packed into compact cartridges while maintaining the ability to release them simultaneously at controlled rates.

Inventive Principle:

Principle #35Parameter changes
