Many people experience difficulty when opening a vacuum-sealed jar. Yet solutions to the problem continue to be tool-based rather than exploring the possibility of innovative changes in product packaging. Improvement depends on gaining knowledge of the capabilities of users, and of using that knowledge as a base for product innovation. To establish such a base we took a sample of 750 subjects and asked them two questions about how they opened jars at home. We then carried out torque measurements using a force transducer shaped like a jam jar. We reached the conclusion that if opening torque was reduced to 2 N m then 97.6% of users between 50 and 94 years of age and 100% of 20-30 year old users would have no difficulty opening a jar.
许多人在打开真空密封罐时会遇到困难。然而，解决这个问题的方法仍然基于工具，而不是探索产品包装创新变革的可能性。改进取决于了解用户的能力，并将这些知识作为产品创新的基础。为了建立这样一个基础，我们抽取了750名受试者作为样本，问了他们两个关于在家如何打开罐子的问题。然后，我们使用一个形状像果酱罐的力传感器进行扭矩测量。我们得出的结论是，如果开启扭矩降低到2 N m，那么50至94岁的用户中有97.6%以及20至30岁的用户中有100%在打开罐子时不会有困难。
