OK繃
核心畫面
You can think of the whole word as one small sticky strip pressed over a cut. It takes two seconds. It hides the sore place and keeps the dirt out. And the cut itself is still there, unchanged, under the pad. Everything this word does comes from that: sometimes you are talking about the strip, sometimes about the act of pressing it on, and sometimes the sore place is not a cut at all but a problem at work.

可以把整個字想成一片壓在傷口上的小 OK 繃。兩秒鐘就貼好了。它把破皮的地方蓋住，也擋住髒東西。而傷口本身還在那裡，在軟墊底下，一點都沒變。這個字的每一種用法都是從這個畫面來的：有時候在說那一片東西，有時候在說貼上去的動作，有時候底下那個「傷口」根本不是傷，而是工作上的一個問題。From the word’s history
Wiktionary records Band-Aid as a trademark registered and coined by Johnson & Johnson in 1924, built as band(age) + aid, and now used as an ordinary word.
維基詞典記載，Band-Aid 是嬌生公司在 1924 年註冊並創造的商標，由 band(age)（繃帶）加 aid（幫助）組成，後來變成大家通用的普通名詞。所以字面上本來就是「幫一下忙的小繃帶」，短短一片，份量本來就不大。
Wiktionary (kaikki extract kaikki:3f6f69a190036ae4:1178333804) entry 'band-aid': 'Genericized trademark from Band-Aid, registered and coined by Johnson & Johnson in 1924 as band(age) + aid.'

貼在問題上的那一片（只蓋住，沒修好）
把同一片 OK 繃從傷口移到問題上：蓋住了，看不到了，底下完全沒動過。
noun · B2
A quick, cheap way of dealing with a problem that only covers it for a while and does not fix what is really wrong. The word shows that the speaker thinks this is not good enough.
