Solution Overview

Problem

Consumer products containing harsh acids, such as phosphoric acid or formic acid, emit strong odors that negatively impact the trigeminal nerve, making it difficult to neutralize these odors effectively with traditional perfume ingredients, as they often compete rather than neutralize the harsh scent.

Innovation Solution

The use of specific perfume raw materials and combinations listed in Tables 1 and 2, which are independent of odor intensity, are capable of neutralizing harsh odors impacting the trigeminal nerve, when incorporated into consumer products or perfume delivery systems at various concentrations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-generated harmful factors

If traditional perfume ingredients with strong intensity are employed to counter the harsh odour, then the odour masking capability is improved, but the effectiveness is worsened as they merely compete with and do not neutralize the original harsh odour

Engineering Contradiction:
Improveharsh odour neutralizationVSAvoidodour neutralization effectiveness
Core Design Contradiction:
Object-generated harmful factorsVSReliability

Solution Approach 1:

The patent changes the chemical parameters of the perfume composition by incorporating specific ingredients (menthol, eucalyptol, camphor, and/or citronellal) that fundamentally alter the interaction mechanism with acid vapors. Instead of competing through intensity, these ingredients chemically interact with the acid molecules to neutralize the harsh odour at the molecular level, transforming the neutralization mechanism from competitive masking to chemical interaction.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent employs a composite perfume formulation combining multiple specific ingredients (menthol, eucalyptol, camphor, citronellal) that work synergistically to neutralize harsh odours. This composite approach creates a multi-functional perfume composition that addresses both the olfactory and trigeminal effects of acid vapors through the combined action of its components.

Inventive Principle:
Principle #40Composite materials

2Productivity

If acids are used in consumer products to remove deposits, then the cleaning effectiveness is improved, but the harsh odour is worsened resulting in negative consumer response

Engineering Contradiction:
Improvedeposit removal effectivenessVSAvoidharsh odour
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent introduces specific perfume ingredients as intermediary substances that mediate between the acid component and the consumer's sensory system. These intermediaries (menthol, eucalyptol, camphor, citronellal) interact with acid vapors to neutralize the harsh odour, allowing the acid to maintain its cleaning function while the intermediary protects the consumer from the unpleasant sensory experience.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent converts the harmful harsh odour generated by acids into a beneficial sensory experience by incorporating ingredients that neutralize the unpleasant effects. The acid's harshness, which originally caused negative consumer response, is transformed into an acceptable or even pleasant olfactory experience through the neutralizing action of the perfume ingredients.

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