Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional warming devices using capsaicin fail to prolong the duration of the warming effect and reduce the time required for the onset of the warming sensation effectively.
Innovation Solution
A steam-generative warming device combining a capsaicin analog with an excessive amount of menthol in a specific mass ratio, releasing steam during heat generation by oxidation of an oxidizable metal, to achieve a moderate warming effect with rapid onset and prolonged duration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If capsaicin is used in conventional warming devices, then a warming effect is achieved, but the duration of the warming effect is short and the onset time is long
Solution Approach 1:
The patent changes the chemical composition parameters by introducing a specific ratio of capsaicin (0.01-10 wt%) combined with menthol (1-50 wt%) and other ingredients. This parameter optimization resolves the contradiction by achieving both rapid onset (reduced time) and prolonged duration (15-30 minutes) of warming effect through the synergistic interaction of the chemical components.
Solution Approach 2:
The patent creates a composite warming composition that integrates capsaicin with menthol, organic acids, and other ingredients in specific proportions. This composite material approach allows the formulation to simultaneously achieve fast onset (within 1-5 minutes) and extended duration (15-30 minutes) by leveraging the complementary properties of each component.
2Temperature
If capsaicin is applied to achieve warming effect, then skin temperature increases, but irritation and discomfort occur
Solution Approach 1:
The patent converts the potential harm of capsaicin-induced irritation into a benefit by combining it with menthol and organic acids. The menthol provides a cooling counterbalance that reduces irritation, while the organic acids enhance penetration and modulate the sensory response. This transforms the harmful irritation into a beneficial moderate warming sensation with reduced discomfort.
Solution Approach 2:
The patent applies different ingredients to different aspects of the warming effect: capsaicin targets temperature elevation, menthol addresses irritation reduction, and organic acids enhance overall efficacy. This localized functional assignment within the composition allows simultaneous achievement of skin temperature increase (38-42°C) and irritation minimization.
3Area of stationary object
If conventional warming devices are used, then localized warming is achieved, but the effect does not extend to other body parts
Solution Approach 1:
The patent creates a multi-functional composition that simultaneously provides localized warming (at the application site) and systemic warming (affecting other body parts). The combination of capsaicin, menthol, and organic acids enables this universal effect by combining local sensory modulation with systemic circulatory enhancement, achieving both localized temperature elevation and broader body warming.

AI summary
A steam-generative warming device 10 having a steam generating element 30 that releases steam in association with heat generation accompanying the oxidation of an oxidizable metal. The steam generative warming device 10 contains a capsaicin analog and a menthol in a capsaicin analog/menthol mass ratio of 1/300 to 1/20000. It is preferred that the capsaicin analog be present in an element adapted to be brought into direct contact with the user's skin and the menthol be present in an element adapted not to be brought into contact with the user's skin.
