Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing cleansing compositions are used, then cleansing function is provided, but they fail to provide stable emulsion and effective moisturizing without rinsing
Solution Approach 1:
The patent combines multiple carrier oils (coconut oil, olive oil, almond oil) with essential oils and specific cleansing agents to create a composite emulsion formulation. This composite approach provides stable moisturizing properties while maintaining cleansing efficacy, resolving the contradiction between emulsion stability and formulation complexity by integrating multiple functional components into a unified composition.
Solution Approach 2:
The patent specifies precise parameter ranges for formulation components, including oil content at 10-30% by volume, essential oils at 0.1-2% by volume, and cleansing agents at 0.1-5% by volume. By optimizing these parameters, the composition achieves stable emulsion formation and effective rinse-free moisturizing, resolving the contradiction between reliability and ease of manufacture through controlled parameter specification.
2Reliability
If high oil content is used for moisturizing, then moisturizing efficacy is improved, but viscosity increases and blocks sprayer nozzles
Solution Approach 1:
The patent optimizes the oil content parameter to 10-30% by volume, which provides sufficient moisturizing efficacy while maintaining viscosity levels that allow the composition to be atomized by sprayers at room temperature. This parameter optimization resolves the contradiction between moisturizing efficacy and sprayability by finding the optimal balance point.
Solution Approach 2:
The patent uses different types of oils with varying viscosity characteristics in specific proportions. Lighter carrier oils like almond oil and olive oil are combined with coconut oil to achieve local quality variations in the formulation, ensuring that the overall composition has appropriate flow properties for spray application while maintaining moisturizing effectiveness at the application site.
3Object-affected harmful factors
If natural ingredients are used, then safety and soothing properties are improved, but antimicrobial efficacy may be reduced
Solution Approach 1:
The patent creates a composite formulation combining multiple natural ingredients with complementary properties. Carrier oils (coconut, olive, almond) provide moisturizing and soothing effects, while essential oils (tea tree, lavender, eucalyptus) contribute antimicrobial and antiseptic properties. This composite approach resolves the contradiction between skin safety and antimicrobial protection by integrating ingredients that perform different functions synergistically.
Solution Approach 2:
The patent selects natural ingredients that serve multiple functions. For example, coconut oil provides both moisturizing and antimicrobial properties, while tea tree oil offers antimicrobial, anti-inflammatory, and soothing effects. This multi-functionality resolves the contradiction between skin safety and antimicrobial protection by using ingredients that simultaneously address multiple concerns.
4Ease of operation
If rinse-free composition is used, then convenience is improved, but residue on skin may cause discomfort
Solution Approach 1:
The patent formulates the composition with specific parameter ranges that enable it to remain on the skin without rinsing. The oil content is optimized at 10-30% to provide sufficient moisturizing without excessive residue, and the cleansing agent concentration is controlled at 0.1-5% to ensure effective cleaning while maintaining skin comfort. This parameter optimization resolves the contradiction between convenience and skin discomfort.
Solution Approach 2:
The patent employs a formulation approach where the composition is applied and then removed with disposable materials such as toilet paper or wipes. This allows the composition to provide its cleansing and moisturizing functions during the brief contact period, then be easily discarded without requiring water rinsing, resolving the contradiction between convenience and potential residue discomfort.
