Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If synthetic polymers are used for temporary hair shaping, then strong and long-lasting shape fixation is achieved, but visible polymer particles appear on hair and natural shine is lost
Solution Approach 1:
The patent changes the fundamental parameter of polymer origin from synthetic fossil-based materials to renewable natural-based materials. The specified polymers (starch, cellulose, chitosan, alginate, gelatin, proteins) are derived from renewable resources and processed to achieve the desired shaping properties without the harmful side effects of synthetic polymers, thereby eliminating visible particles while maintaining shape fixation.
Solution Approach 2:
The patent employs composite material systems by combining multiple natural-based polymers (starch, cellulose, chitosan, alginate, gelatin, or proteins) in specific compositions. These composite formulations leverage the synergistic properties of different biopolymers to achieve strong shape fixation and volume effect while maintaining hair health and avoiding visible particles on the hair surface.
2Reliability
If synthetic polymers are used for temporary hair shaping, then stable support for hairstyle is achieved, but hair health and natural shine are compromised
Solution Approach 1:
The patent transitions from synthetic polymer chemistry to natural polymer chemistry, fundamentally changing the material composition parameter. The specified natural-based polymers (starch, cellulose, chitosan, alginate, gelatin, proteins) inherently provide hair conditioning and shine properties while delivering stable hairstyle support, thus eliminating the trade-off between hold strength and hair health.
Solution Approach 2:
The patent utilizes composite formulations of multiple natural-based polymers that work synergistically to provide both structural support for the hairstyle and conditioning benefits for the hair. The combination of polymers from renewable sources creates a system that simultaneously achieves stable hairstyle support and maintains hair health and natural shine.
3Use of energy by moving object
If synthetic polymers are used, then production is energy-intensive from fossil materials, but renewable alternatives must provide equivalent performance
Solution Approach 1:
The patent fundamentally changes the raw material source parameter from fossil-based synthetic polymers to renewable natural-based polymers (starch, cellulose, chitosan, alginate, gelatin, proteins). This parameter change reduces the carbon footprint and energy intensity of production while maintaining or improving shaping performance through the inherent properties of these biopolymers.
Solution Approach 2:
The patent develops composite material systems using multiple natural-based polymers that compensate for any individual polymer limitations, ensuring equivalent or superior shaping performance compared to synthetic alternatives. The synergistic combination of biopolymers achieves the required hairstyle support, volume effect, and hold strength while being environmentally sustainable.
4Loss of substance
If natural-based polymers are used, then renewable resources are utilized, but sufficient shape fixation and volume effect must be achieved
Solution Approach 1:
The patent changes the material origin parameter to renewable natural-based polymers, eliminating dependence on fossil resources. The specified polymers (starch, cellulose, chitosan, alginate, gelatin, proteins) are derived from sustainable sources and processed to achieve shape fixation strengths comparable to or exceeding synthetic alternatives, while providing additional hair conditioning benefits.
Solution Approach 2:
The patent employs composite formulations combining multiple natural-based polymers to achieve synergistic effects that provide sufficient shape fixation strength and volume effect. The composite system leverages the complementary properties of different biopolymers to ensure reliable hairstyle support while maintaining sustainability and hair health.
