* 最早解决技术创新问题是靠试误法，就是试遍所有可能的方案。很长的时期内，对方案的选择，都是瞎猜瞎碰的。在这段漫长的岁月里，人们积累了大量技术创新经验与有关物质特性的知识。这些知识的利用，提高了发现的方向性，使得解决问题的过程有序化了。但问题本身也发生了变化，随着时间的推移问题越来越复杂。直到今天，为了找到一个需要的解决方案，也得作大量的无效尝试。??????试误法及在这一基础上建立起来的创造性劳动组织，是与现代科学技术创新的要求相矛盾的。现在需要新的、能够大大减少无效尝试数量的控制创新过程的方法，也需要新的、能够有效地运用新方法的创新过程组织法。为此，必须要有一套科学的并行之有效的解决技术创新问题的理论。???? * 注：1.为更好的保温，将塑钢窗加厚 ;用载重量更大和重型卡车代替轻型卡车 2.斧头的空心手柄,配备灭火器的焊接装置 3.子午线轮胎，汽车上用自动传动系统代替机械传动系统、原珠笔、登山自行车、计算机用的鼠标 4.内燃机、记忆合金做管接头(形状记忆合金用于管道结合，用记忆合金制成套管可以代替焊接，方法是在低温时将管端内径全扩大约 4％，装配时套接一起，一经加热，套管收缩恢复原形，形成紧密的接合。美国海军飞机的液压系统使用了10万个这种接头，多年来从未发生漏油和破损)集成电路的发明、充气轮胎，记忆合金 5、轮子、蒸汽机、飞机 Proprietary to General Electric Company * Example originated from sweet pepper industry in Bulgaria – used to use sharp knives – peppers had different shapes/sizes, so couldn’t automate knife process Proprietary to General Electric Company * Nobody knows how many years this method has been used. Maybe more than 100 years. It is a traditional way to produce popcorn in China. Nobody knows how many years this method has been used. The corn is placed inside the iron tube with sugar. The put the tube on the fire. In order the achieve good uniformity, the tube should be rotated. When the temperature goes up, the pressure of the tube will also go up. Then open the gasket suddenly to release the pressure. There is always with a big bang during the pressure reduction. The corn will expand. The sweet popcorn comes. Another example – potato in pressure cooker * * Six Hats White Hat : (facts) Red Hat : (emotions) Black Hat : (negative judgement) Yellow Hat : (positive speculation) Green Hat : (creativity) Blue Hat : (control of thinking) Lateral Thinking Thinking modes????????????????????????
