Solution Overview

Problem

Current wax bead candles are difficult to mass-produce and require consumer assembly, with wicks and beads prone to shifting during transportation and use, leading to uneven appearance and fragrance distribution.

Innovation Solution

A scented candle design featuring a vessel filled with small wax beads (0.35-2.35 mm diameter) topped with a solid wax layer, which holds the beads and wick in place, allowing for pre-assembled, high-volume manufacturing and enhanced fragrance release.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If wax beads are used in a candle, then fragrance release and aesthetic appearance are improved, but the candle becomes difficult to mass-produce and requires consumer assembly

Engineering Contradiction:
Improvemass production capabilityVSAvoidassembly requirement
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The patent applies preliminary action by pre-assembling the wax beads, wick, and container into a complete candle before shipping to the consumer. This eliminates the need for consumer assembly while maintaining the aesthetic and functional benefits of wax bead candles. The manufacturer performs the assembly process in advance during production.

Inventive Principle:
Principle #10Preliminary action

2Stability of the object's composition

If wax beads are used without a solid topping layer, then manufacturing simplicity is maintained, but wicks and beads shift during transportation and use

Engineering Contradiction:
Improvewick and bead position stabilityVSAvoidcandle structure
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent uses a composite structure combining loose wax beads with a solid wax topping layer. The solid topping acts as a matrix that embeds and stabilizes both the wax beads and wick, preventing them from shifting during transportation and use. This composite approach maintains structural integrity while preserving the aesthetic qualities of bead candles.

Inventive Principle:
Principle #40Composite materials

3Stability of the object's composition

If a solid wax topping layer is added to hold beads and wick in place, then position stability is improved, but manufacturing complexity increases

Engineering Contradiction:
Improvebead and wick positioningVSAvoidmanufacturing process simplicity
Core Design Contradiction:
Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The patent changes the physical state parameter of wax from loose individual beads to a solidified topping layer. By controlling the temperature and phase of the wax during manufacturing, the solid topping is poured over the beads and wick, then allowed to cool and set, creating a stable matrix that holds components in place without requiring complex assembly mechanisms.

Inventive Principle:
Principle #35Parameter changes

4Stability of the object's composition

If pre-assembly is performed to maintain wick centrality, then wick position stability is improved, but production time and cost increase

Engineering Contradiction:
Improvewick centralityVSAvoidmanufacturing speed
Core Design Contradiction:
Stability of the object's compositionVSProductivity

Solution Approach 1:

The patent employs self-service mechanisms where the solid wax topping automatically holds the wick in a centralized location through its solidifying process. The wick is positioned centrally before the solid topping is applied, and as the topping cools and hardens, it naturally maintains the wick's central position without requiring continuous external intervention or complex positioning mechanisms throughout production.

Inventive Principle:
Principle #25Self-service

Applied Scientific Principles
