Every project has its quirks - when some little problem throws up an odd aside from the main activity that requires investigation. Sometimes it turns out to be a red herring. Occasionally it can change the whole design. Colin Ledsome CEng FIED highlights another such instance We've all used roller towels at some time. A compact unit on the wall has a length of towel hanging down at the front, which loops up to the back. Once you have dried your hands, you pull down a clean length of towel and the excess rolls up into the back of the machine. The mechanism locks for a few seconds before you can pull any more down. This discourages users from using an excessive amount of towel and provides a clean towel for each user.

机译：每个项目都有其怪癖-当一些小问题与需要调查的主要活动相去甚远时。有时结果是一条红鲱鱼。有时它可以更改整个设计。 Colin Ledsome CEng FIED突出了另一个这样的例子。我们有时都使用过滚筒毛巾。墙上的一个紧凑单元，其前部悬挂着一定长度的毛巾，该毛巾向上延伸至后部。一旦干了手，就拉下干净的毛巾，多余的毛巾会卷入机器的背面。该机制会锁定几秒钟，然后才能将其拉下。这不鼓励用户使用过多的毛巾，并为每个用户提供干净的毛巾。
