Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of substance

If reduced weight packaging is used to lower carbon footprint, then plastic consumption and environmental impact are reduced, but the container becomes more susceptible to premature leakage and breakage due to chemical activity

Engineering Contradiction:

Improveplastic consumptionVSAvoidcontainer stability

Core Design Contradiction:

Loss of substanceVSReliability

Solution Approach 1:

The patent introduces xanthine compounds as intermediary substances that mediate between the oxidizing composition and the flexible container material. These compounds act as stabilizing agents that prevent direct harmful interactions between the chemical composition and the plastic, thereby preventing premature degradation while allowing the use of reduced weight packaging.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent modifies the chemical parameters of the oxidizing composition by adjusting the pH to a specific range (1-6) and incorporating xanthine compounds at defined concentrations. This parameter optimization stabilizes the composition's chemical activity, preventing excessive oxidation that would degrade the container material, thus enabling thinner, lighter packaging without compromising integrity.

Inventive Principle:

Principle #35Parameter changes

2Loss of substance

If flexible packaging is used to reduce carbon footprint, then plastic consumption is reduced, but the container becomes more vulnerable to chemical degradation and breakage

Engineering Contradiction:

Improveplastic consumptionVSAvoidchemical degradation

Core Design Contradiction:

Loss of substanceVSObject-affected harmful factors

Solution Approach 1:

Xanthine compounds serve as protective intermediaries between the oxidizing composition and the flexible container. They absorb or neutralize excessive oxidizing activity that would otherwise attack the plastic polymer chains, thereby protecting the container from chemical degradation while maintaining the benefits of flexible, reduced-weight packaging.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent converts the potentially harmful oxidizing activity of the composition into a beneficial effect. By controlling the pH and adding xanthine compounds, the oxidation process is harnessed to stabilize the container material rather than degrade it, turning what would be a harmful factor into a protective mechanism that extends container life.

Inventive Principle:

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

3Productivity

If high chemical activity is present in the product, then the cosmetic composition is more effective, but the container experiences premature leakage and breakage

Engineering Contradiction:

Improvecosmetic composition effectivenessVSAvoidcontainer integrity

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent optimizes the chemical parameters of the oxidizing composition by controlling pH within the range of 1-6 and incorporating xanthine compounds. These parameter adjustments modulate the chemical activity to an optimal level that maintains cosmetic effectiveness while preventing excessive oxidation that would compromise container integrity, thus resolving the contradiction between effectiveness and stability.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

Xanthine compounds act as mediating substances that allow the high chemical activity of the oxidizing composition to coexist with container integrity. They intercept and neutralize excessive oxidizing radicals before they can attack the container material, thereby maintaining both the effectiveness of the cosmetic active ingredients and the reliability of the container.

Inventive Principle:

Principle #24Intermediary (Mediator)

Applied Scientific Principles

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 xanthine compounds maintain the stability and flexibility of the flexible container, preventing premature breakage and leakage, while reducing plastic consumption and environmental impact.

Implementation Method 1

Xanthines maintain the stability of flexible containers filled with aqueous oxidizing compositions comprising hydrogen peroxide at room and elevated temperature alike. Xanthines thereby prevented premature breakage and leaking of the flexible container, maintained flexibility of the plastic material, and prevented the formation of discolorations of the plastic materials.
