Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a polymer for hair setting is used to provide fixing effect, then hair setting holding force is improved, but flaking phenomenon occurs and tactile sensation deteriorates
Solution Approach 1:
The patent changes the chemical parameters of the polymer by introducing specific graft copolymer structures with controlled composition ratios. The polymer contains a main chain with graft chains where the graft chain content is specifically controlled at 10-50% to optimize both holding force and reduce flaking. This parameter optimization resolves the contradiction between strength and harmful effects.
Solution Approach 2:
The patent uses a composite polymer structure consisting of a main chain and grafted chains with different properties. The graft copolymer combines the holding power of the main chain with the flexibility and anti-flaking properties of the grafted chains. This composite structure allows the material to simultaneously provide strong fixing effect while minimizing flaking and improving tactile sensation.
2Ease of operation
If a silicone-grafted organic main chain polymer is used to improve hair touch, then tactile sensation is improved, but beading phenomenon occurs
Solution Approach 1:
The patent optimizes the physical parameters of the polymer including molecular weight, graft chain content, and composition ratios. By controlling the graft chain content at 10-50% and adjusting the molecular weight distribution, the patent achieves uniform spray dispersion that prevents beading while maintaining improved tactile sensation from the silicone grafts.
3Strength
If conventional polymers are used for hair setting, then setting hold is achieved, but beautiful sensation deteriorates due to excessive hardness
Solution Approach 1:
The patent modifies the mechanical properties of the polymer by controlling the graft chain content and composition. The specific parameter optimization creates a polymer with balanced hardness - strong enough for setting hold but flexible enough to avoid excessive rigidity. The graft copolymer structure provides this balance by combining rigid and flexible segments at optimal ratios.
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 composition reduces flaking and beading, enhances tactile sensation, and ensures effective cleansing without compromising hair styling hold.
Implementation Method 1
when the solvent (for example, a liquefied gas such as ethanol or LPG) is evaporated after the spray composition is sprayed onto the hair, the polymer for hair setting forms a film on the hair surface
