Scent-Changing Ointment Managing Olfactory Fatigue
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing topical ointments for dry skin often suffer from olfactory fatigue, where the sense of smell becomes desensitized to a particular fragrance after prolonged exposure, reducing their appeal and effectiveness.
Innovation Solution
A Hemp/CBD oil-based topical ointment that gradually changes its scent from camphor and menthol to vanilla and finally to coconut oil, minimizing olfactory fatigue and enhancing user appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a single fragrance is used in topical ointment, then the ointment has a consistent scent, but olfactory fatigue occurs after prolonged exposure
Solution Approach 1:
The patent applies the dynamics principle by formulating a multi-component fragrance system where different scent components become dominant at different times. The ointment contains multiple fragrance compounds that evaporate or become perceptible at different rates, causing the scent profile to dynamically change over time rather than remaining static. This dynamic scent evolution prevents olfactory fatigue by continuously presenting new olfactory stimuli to the user.
Solution Approach 2:
The patent employs parameter changes by varying the volatility, concentration, and chemical composition parameters of the fragrance components. By selecting compounds with different vapor pressures and degradation rates, the scent intensity and character parameters change over time. This allows the ointment to transition between different scent phases, maintaining user engagement while providing consistent therapeutic benefits.
2Reliability
If multiple fragrance components are used to prevent olfactory fatigue, then user appeal is maintained over time, but the formulation complexity increases
Solution Approach 1:
The patent applies the merging principle by combining multiple fragrance components into a single integrated ointment formulation. Rather than using separate products or complex delivery systems, all fragrance compounds are merged into one cohesive formulation that applies simultaneously to the skin. This simplifies the user experience while achieving the goal of preventing olfactory fatigue through multi-component scent evolution.
Solution Approach 2:
The patent employs universality by designing a fragrance system that serves multiple functions: providing initial sensory appeal, maintaining long-term user engagement, and potentially offering different therapeutic benefits at different times. The same multi-component fragrance formulation universally addresses both short-term attraction and long-term compliance needs, eliminating the need for separate products or complex switching mechanisms.
3Ease of operation
If the ointment melts on the skin for easy application, then ease of operation is improved, but the ointment may melt in storage at higher temperatures
Solution Approach 1:
The patent applies phase transitions by formulating the ointment with a specific melting point range that enables it to transition from solid to liquid phase at skin temperature during application, but remains stable in solid form at typical storage temperatures. This controlled phase transition behavior allows the ointment to be solid for stable storage and transport, then become liquid for easy spreading and absorption on the skin.
Solution Approach 2:
The patent employs parameter changes by carefully selecting and adjusting the melting point parameter of the ointment formulation through choice of base ingredients and their proportions. The formulation is designed to have a melting point parameter that falls within a specific range - high enough to prevent melting during storage but low enough to allow melting during normal skin contact. This parameter optimization resolves the contradiction between storage stability and application ease.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The ointment effectively treats dry skin while continuously changing its scent to maintain user engagement and reduce olfactory fatigue, providing both therapeutic and appealing properties.
Implementation Method 1
the ointment initially has a scent of camphor and menthol. After a few minutes the scent changes to vanilla; and lastly, the smell gradually changes into a coconut oil scent
