弄出來的東西與辦法
這一組就是核心畫面的兩種成果。一種摸得到，一種摸不到，但都是有人坐下來想出來、拼出來的。

核心畫面
To contrive is to work something out and put it together. A contrivance is what comes out of that work — a thing somebody made on purpose, for one job. The making still shows on it. Hold that picture and the other uses follow: the plan is a contrivance you cannot touch, and the criticism is what happens when the making shows too much.

contrive 是「動腦筋把東西弄出來」。contrivance 可以想成是那個弄出來的成果：為了一件事特地做出來的東西，而且身上還看得見人工的痕跡。抓住這個畫面，另外兩個用法就接得上了。一個是把東西換成辦法：弄出來的不是機器，是一套安排。另一個是把痕跡當缺點：做的痕跡太明顯，讀者就看穿了。From the word’s history
Wiktionary gives contrivance as contrive + -ance, with the suffix arriving through Old French -ance from Latin -antia. A suffix that turns a verb into the action or the result of it fits all three uses: the thing made, the plan made, and the making that shows.
資料說 contrivance 是 contrive 加上字尾 -ance；-ance 這一路從古法文 -ance、拉丁文 -antia 過來，作用是把動詞變成「那個動作」或「那個成果」的名詞。所以字面上就是「弄出來這件事／弄出來的東西」。三個用法剛好都落在這兩個位置上：做出來的機器、想出來的辦法，以及「做的痕跡」本身。

痕跡被看見的時候
同樣是「人工做出來」的痕跡，這一組把它當成缺點在講。東西做得好，你不會注意到它是被做出來的；一被看穿，這個字就轉成批評。
