[생각의 새로운 방법_TRIZ]Theory of Inventive Problem Solving_127 TRIZ is a tool for creative problem-solving, utilizing 40 inventive principles to address technical challenges. Beginners may find it difficult to identify and resolve contradictions directly, so applying the 40 principles one by one is recommended for practice. Deep understanding and internalization of each principle through examples are essential. Over time, experience helps improve the abilit.. 더보기
[생각의 새로운 방법_TRIZ]Theory of Inventive Problem Solving_126 TRIZ is a powerful tool for creative problem-solving, but only Russian experts seem to effectively apply it due to a lack of comprehensive education and practical problem-solving experience elsewhere. Companies have adopted TRIZ via software tools and hiring Russian experts, yet neither approach ensures deep knowledge integration. The essence of TRIZ, including resolving contradictions and using.. 더보기
[생각의 새로운 방법_TRIZ]Theory of Inventive Problem Solving_125 TRIZ (Theory of Inventive Problem Solving) originated from Genrich Altshuller in Russia, who analyzed 200,000 patents to identify common principles in creative problem solving. He emphasized overcoming contradictions as the key, distinguishing between technical contradictions (conflicts between two technical parameters) and physical contradictions (a single parameter needing conflicting values s.. 더보기
[생각의 새로운 방법_TRIZ]Theory of Inventive Problem Solving_124 The TRIZ method (Theory of Inventive Problem Solving) focuses on achieving "Ideal Final Results (IFR)"—solutions that maximize effect while minimizing cost. A case study of a maritime accident in Estonia demonstrates TRIZ's application in resolving real-world problems. TRIZ experts proposed innovative solutions like water-utilizing mechanisms to stabilize ships and practical sliding door designs.. 더보기
[화학&고분자_유화 비법서]계면활성제 합성 및 응용기술_123 Surface-active agents, commonly called surfactants, are compounds that alter the properties of interfaces between different phases, such as air-liquid or liquid-solid. Cationic surfactants are characterized by a positive charge and are less commonly used due to their lower cleaning power compared to anionic surfactants. Amphoteric surfactants, which contain both positive and negative charges, di.. 더보기
[화학&고분자_유화 비법서]계면활성제 합성 및 응용기술_122 Anionic surfactants have evolved since their industrialization in 1817 by BASF. Initially used in textiles, their applications now span industries such as cosmetics, construction, and food. Their affordability, ease of manufacture, and excellent properties have made them staples in detergents and industrial cleaners. The primary functional groups are carboxylic acids, sulfate esters, and sulfoni.. 더보기
[화학&고분자_유화 비법서]계면활성제 합성 및 응용기술_121 Surfactants are synthesized from hydrophobic raw materials derived from animal/plant oils or petroleum, combined with hydrophilic groups. Their production involves processes like sulfonation and esterification to create anionic, cationic, nonionic, or amphoteric surfactants. Environmental concerns have shifted the focus to eco-friendly and biodegradable surfactants, especially for home and indus.. 더보기
[화학&고분자_유화 비법서]계면활성제 합성 및 응용기술_120 Surfactants are classified into ionic (anionic, cationic, amphoteric) and non-ionic types and are composed of hydrophilic and hydrophobic parts that alter the properties of surfaces and interfaces. Major application fields include textiles, household detergents, paper manufacturing, pesticides, pharmaceuticals, paints, cosmetics, and food, with textiles and household detergents accounting for th.. 더보기
