11.5.4 Analogy

Analogy draws on similar situations to provide ideas for invention and design. Alexander Graham Bell used the analogy of the human ear when designing telephone apparatus to receive sound. As mentioned above, his first receivers were much better than his transmitters where the analogy with the ear didn't work as well. When devising their flying machine, the Wright brothers used the analogy of soaring birds twisting their wings to restore balance. They designed the wings of their aircraft to be

11.1 Five steps to invention

I've looked at what motivates people and organisations to invent. I'll look more closely now at what's actually involved in inventing something.

Wherever invention occurs, whether with a lone inventor or in a creative team within an organisation, there seem to be common factors involved. There have been many attempts over the past 100 years to explain the creative process that occurs while people are attempting to solve problems. I'm going to combine ideas from two such models of the st

4.9 A consumer's experience of innovation

First phone in 1968

As I mentioned earlier my parents first acquired a domestic telephone in 1968 – more than 90 years after its invention.

Before then other ways of communicating seemed good enough. In the early 1950s in our street of around 100 houses only one family had a private telephone. My family used public call boxes occasionally but we didn't know many people with their own phone so not many calls needed to be made. When we needed to communicate with people at a

4.7 Has telephone design changed over time?

As you can see from Figure 5 the design of the telephone has changed considerably over its lifetime, reflecting the improvements in technology, materials, components and manufacturing processes. Figures 1(a) to (f) show some of the early progress. Author(s): The Open University

4.2 When and where was the telephone invented?

I'd read in the past that the telephone was invented in 1876 by Alexander Graham Bell. However when I looked more closely at the history it turns out that the idea had been ‘in the air’ for almost half a century.

The distance communication technology of the time, the telegraph, was based on sending pulses of electricity along a wire to control an electromagnet at the receiving end. The sender completed an electric circuit by pressing a key and the receiver's electromagnet controlled

I will now elaborate on my answer from Exercise 1. I'm doing this because my internet search revealed more than I've written in the above answer, and to show that the invention of the telephone and its use by consumers is not as plain and simple as you may think. You we

2.2 The inventive drive

What events and ideas spurred people to come up with thousands of inventions in the last 100 years?

Ron Hickman was a do-it-yourself enthusiast who damaged a chair being used to support a piece of wood he was sawing. Instead of merely being annoyed at the accident he set about designing and building a prototype of a combined workbench and sawhorse to prevent further damage to his furniture. This became the Workmate (Author(s): The Open University

1.3.4 Diagrams for connectivity

Relationship diagrams offer one way of putting more order into your understanding of a situation. Each element of a situation is named in an oval and lines between ovals indicate that there are relationships between the particular elements – but no more than this!

Systems maps are another way of developing one's understanding of a situation. Systems maps are essentially ‘structure’ diagrams. Each element or sub-system is contained in a circle or oval and a line is d

Diagrams are normally intended to describe either structure or process and not both. Table 1 gives a classification of diagram types by structure or process. Another way to view this is to note that there are diagram types that represent largely static relationships and those that represent situ

4 Who are the users?

This section reveals that ‘users’ can include a wide variety of people – not just the final purchasers or consumers of a product. The section also makes the case for strong user representation in the design process.

Of course, it is not only me who uses the various products in my home; other people use them as well, both members of the family and visitors. Sometimes the range of users of a product, and their different needs, can be diverse. And in addition to the obvious or intend

5.10 Fluoridation

The addition of fluoride to water has caused much controversy and public debate. The problem seems to be that some see it as the addition of a poison, and others see it as the use of mass medication whether the individual wishes it or not.

Many waters do, however, have a natural fluoride content (Figure 33) and it has been suggested that the presence of fluoride in a concentration of 1.0 mg l−1 is beneficial in preventing dental decay. Above this concentration there is the

8 Voice

Is the speaker in a poem one and the same as the writer? Stop and consider this for a few moments. Can you think of any poems you have read where a writer has created a character, or persona, whose voice we hear when we read?

Wordsworth's The Prelude was written as an autobiographical poem, but there are many instances where it is obvious that poet and persona are different. Charlotte Mew's poem, ‘The Farmer's Bride’ (1916) begins like this:

1.7 Babylonian mathematical style

Not only should you have learnt through this exercise more about the Babylonian mathematical style, but also, on another level, you should have gained more experience in the endeavour of trying to understand past mathematics. The model that we have been trying out can be characterised thus: use any means, any symbolism or notation that occurs to you, to find your way into the problem, then check rigorously to see how much of your new understanding is more a projection backwards from your own

4.3 Religion and political stability

Wilberforce’s whole approach is strong indirect testimony to the predominance among his contemporaries of the kinds of religious outlook he is criticising, although objective evaluation requires a detachment from his own Evangelical zeal. Certainly his portrayal of the dominant tone of late eighteenth-century Christianity as one of undemanding endorsement of social harmony, decency and good neighbourliness rings true. A leading theological influence was that of William Paley (1743–1805) w

4.5 The cases in Latin

‘Cases’ indicate the various functions that nouns, pronouns and adjectives can have in a sentence. The case is shown by the word-ending in Latin.

Although learning about cases is not within the scope of this introductory unit, it may help to have a short checklist of the cases and how they may be translated into English from Latin.
