Solution Overview

Problem

Candles made with natural waxes often leave difficult-to-remove residue in containers, posing safety hazards and environmental concerns, as consumers struggle to extract the after-burn residue without damaging the vessel.

Innovation Solution

A wax formulation comprising stearic acid, a natural wax, and a volatile active substance, designed to pull away from the container surface upon cooling, facilitating easy residue removal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If natural wax is used in candle formulations, then sustainability and eco-friendliness are improved, but residue removal difficulty increases

Engineering Contradiction:
ImprovesustainabilityVSAvoidresidue removal
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent modifies the physical and chemical parameters of natural wax by adding stearic acid (5-20% by weight) and volatile active substances (20-40% by weight), changing the wax's crystalline structure and cooling characteristics to enable easier residue removal while preserving sustainability

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite wax formulation combining natural wax with stearic acid and volatile active substances, leveraging the complementary properties of each component: natural wax provides sustainability, stearic acid enhances structure and release characteristics, and volatile substances improve burn properties

Inventive Principle:
Principle #40Composite materials

2Reliability

If natural wax formulations are used in containers, then eco-friendliness is improved, but safety hazards from difficult residue removal increase

Engineering Contradiction:
Improveeco-friendlinessVSAvoidsafety hazards
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the thermal and mechanical parameters of the wax formulation through stearic acid addition, modifying how the wax contracts during cooling to prevent adherence to container surfaces, thereby eliminating the need for forceful removal that causes safety hazards

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent converts the naturally high adhesion property of pure natural wax, which causes residue to stick to containers, into a benefit by adding stearic acid that creates a controlled release mechanism, allowing the wax to adhere during burning but release easily after cooling

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

3Stability of the object's composition

If conventional wax formulations are used, then residue adhesion to containers occurs, but formulation complexity increases with additives

Engineering Contradiction:
Improveresidue adhesionVSAvoidformulation complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent uses stearic acid at a specific concentration range (5-20% by weight) to modify the crystalline structure and cooling contraction of the wax formulation, achieving controlled residue release without requiring complex multi-component systems

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent applies stearic acid and volatile active substances specifically to modify the interface between the wax and container surface, creating localized properties that enable easy release while maintaining the bulk natural wax composition for sustainability

Inventive Principle:
Principle #3Local quality
