Summary

Introduction

It may be a good way to illustrate the absorbing intellectual problems presented by engineering design to recount some of the more interesting examples that have come my way, and so I have added this new chapter to the second edition. Several themes emerge, for instance, that there is nothing new under the sun and that most, if not all, invention reduces to the adapation of old ideas to new circumstances or new functions. Another is that contemplating a problem in a ruminative frame of mind may lead to a feeling that there must be a better way than those so far thought of. Known solutions sometimes have a hint of the digging of holes simply to fill them up again, which may be a pointer to such a better way, if we can only spot what it is.

The spotting of a case of digging a hole to fill it up is one example of the important insights which mark the progress of much design. Often it is only after a lot of apparently fruitless work that there suddenly dawns a great light, and we know where we are going. There is then rapid progress for a while, but alas, there are often further struggles before we achieve a satisfactory conclusion, if indeed we ever do.
