结构设计改良集锦

The phone rings. I answer. It's my future mother-in-law. We talk. She says, "Let me put Murray on." I wait. Click. The phone is disconnected! I get a call back in a minute. "Hi, Murray accidently hung up the phone."  
Why did Murray accidently hang up the phone? Well, here is a picture of the phone. Notice the on-off switch on the side. (See arrow.) This switch is in a bad location because it is on the "handle" of the phone. As a result, the phone user accidently turns the phone off, which causes the phone to disconnect! This seems to happen frequently when handing the phone to someone, switching ears or repositioning the phone.  
  
Design suggestion
One solution would be to move the switch away from the handle. If the purpose of locating the switch on the handle is to make it easy to turn the phone on or off with one hand, then recessing the switch below the surface of the phone would help avoid accidental switching.

A friend told me he was confused by the switches on his coffee maker (See photo.) Each switch has a light on it. The top switch turns the coffee maker on and off. When it is on, its light goes on. No light appears when the coffee maker is off.  
The bottom switch selects the quantity of coffee desired, either a) the smaller quantity of 3 or fewer cups or b) the larger quantity of 4 or more cups. The problem is with the light on this bottom switch. When would you expect the switch light to go on, for the smaller quantity or for the larger quantity?  
  
If you said that the light goes on when the switch is set to the larger quantity of 4 or more cups, you would be wrong. The quantity light ONLY goes on for the smaller quantity, three cups or less. It does NOT go on for the larger quantity, 4 or more cups.  
  
Why is this confusing? People naturally expect more coffee to be associated with more light (light on) and less coffee to be associated with less light (light off).  
  
Design Suggestions
Change the operation of the coffee quantity switch so that the light goes on when the coffee quantity is set to make more cups of coffee, not fewer cups. This change would involve switching the positions of the "min...3" and "4...max" labels.
Remove the light from the coffee quantity switch.  
Consider removing the coffee quantity switch entirely. Most coffee makers don't have one.

我顶一下

其实有八成以上的手机就是这样开关机的！它的作用是避免不小心的误操作及碰撞该按键所造成的意外开关机，所以用“时间”来判别是否“真假”开关机。这方法是非常简单有效，才得到众多手机厂家的应用！
版主所提倡的“独立开关健”及“贴告示”，我觉的不妥！理由是：
1.在打造一个精致及简洁至上的产品的时候，这些方法是与之相违背的。
2.完全可以把它是当作一个常识来认识，你看多少人都这么用过来！或者拿起说明书看一看！就象我们在window系统里打开一个文件，如果设定为“双击”，你就必须用鼠标点两下，单击就不行一样的道理！

谢谢，derech指教，建议竹斑加分啊！

  
出差两天刚回来，发现又加了一分。
这样也能加分！！！，谢谢斑竹，也谢谢davidlfxu。

版主从哪里搞到这么多的资料啊！

版主真是厉害，让人不得不佩服。
可以再来一点吗？多谢了！

可以再来几个。谢谢！

这样的不合理的设计的确现实中存在不少，关键就是要大家在设计的时候多考虑一下思维和使用习惯，比如这个灯亮很容易让人想到用到更强的功能时才亮，很有启发。
