Solution Overview

Problem

Conventional wick holders for candles often result in suboptimal burning due to insufficient liquid candle material being drawn up by the wick, caused by adhesion issues and deformation during clamping, leading to clogging and reduced burning time.

Innovation Solution

A wick holder with a base sheet and a sleeve-like body featuring side openings and an additional fold line to prevent deformation, allowing lateral flow of liquid candle material and ensuring stable wick positioning, which enhances the supply of wax to the wick and maintains the candle's burning duration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the wick holder is adhered in a holder with glue, then the wick holder is fixed in position, but the glue clogs the wick and causes undesired adhesion of the wick to the wick holder

Engineering Contradiction:
Improvefixed position of wick holderVSAvoidwick flow capability
Core Design Contradiction:
Stability of the object's compositionVSReliability

Solution Approach 1:

The wick holder is divided into functionally distinct zones: a base sheet for positioning and a sleeve-like body for wick reception. The side openings segment the wax supply path, allowing lateral inflow independent of the base sheet area, thereby preventing glue clogging while maintaining fixed positioning.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces side openings that enable lateral (horizontal) inflow of liquid candle material, adding a dimensional aspect to wax supply that complements the vertical supply from the base sheet. This multi-directional supply ensures continuous wax flow even when one path is blocked by glue.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Area of stationary object

If the base sheet becomes larger, then the wick holder provides better support, but the problem of insufficient liquid candle material supply worsens due to increased distance from wick

Engineering Contradiction:
Improvebase sheet areaVSAvoidliquid candle material supply
Core Design Contradiction:
Area of stationary objectVSQuantity of substance

Solution Approach 1:

Side openings are positioned at the transition zone between base sheet and sleeve-like body, enabling lateral wax inflow that bypasses the distance limitation. This creates a shorter supply path from the side openings directly to the wick, ensuring adequate wax supply even when the base sheet is large.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The side openings act as intermediary channels that facilitate lateral wax flow to the wick, supplementing the primary vertical supply path from the base sheet. This dual-path system ensures reliable wax delivery independent of base sheet size.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Object-affected harmful factors

If the wick holder height is increased, then the flame is prevented from coming too close to the bottom, but the device becomes more complex

Engineering Contradiction:
Improveflame proximity to bottomVSAvoidwick holder structure
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The sleeve-like body serves multiple functions simultaneously: it receives and positions the wick vertically, provides structural support to prevent flame contact with the bottom, and incorporates side openings for lateral wax supply. This multi-functionality achieves safety without proportionally increasing complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent merges the wick positioning function and the wax supply function into a single integrated sleeve-like body structure. The side openings are incorporated directly into this body, combining structural support with fuel delivery in one component rather than separate elements.

Inventive Principle:
Principle #5Merging (Combining)

4Stability of the object's composition

If the wick holder is crimped to hold the wick, then the wick is secured in place, but the base sheet deforms during the crimping operation

Engineering Contradiction:
Improvewick positioningVSAvoidbase sheet flatness
Core Design Contradiction:
Stability of the object's compositionVSManufacturing precision

Solution Approach 1:

The wick holder is segmented into a base sheet and a separate sleeve-like body. The crimping operation is applied only to the sleeve-like body to secure the wick, while the base sheet remains unaffected and maintains its flatness. This functional segmentation protects the base sheet from deformation.

Inventive Principle:
Principle #1Segmentation
