Apparency Half a century ago, Stern discussed this attribute of an artistic object and called it apparency. While art is not limited to this single end, he felt that one of its two basic functions was "to create images which by clarity and harmony of form fulfill the need for vividly comprehensible appearance." In his mind, this was an essential first step toward the expression of inner meaning. Kevin Lynch, The Image of the City artmeaningimagesharmonyform
The minimum condition When a device is so designed that its component parts are only just strong enough to get the intended result without danger of failure, we may say it is in its minimum condition. I suspect that the functionalists sometimes meant by functional design simply design aimed at the minimum condition for a device. In that case 'form should follow function' would mean that every system should be in its minimum condition, thus having certain limitations imposed on its form.
