Density;

Higher mass/weight to aid stability;

Award [1] for identifying one physical property that makes hardwood a suitable choice for the base for the Gramovox^® bluetooth speaker and [1] for a brief explanation up to [2 max].

Retro-styling uses the decoration/style/appearance from a particular period of time;

The S-curve horn of the Gramovox^® mimics the shape of gramophones from the past (1920s);

Using bluetooth/up to date/new technology.

Award [1] for each distinct point in an explanation of how retro-styling has been used in the design of the Gramovox^® bluetooth speaker up to [3 max].

(Answer in brackets not required for the mark.)

Entrepreneur
An influential individual who can take an invention to market;
Bapu created a crowdfunding campaign to support the development of the speaker;
Lowering financial risk (for him/the company);

Product champion
Develops enthusiasm for a particular idea or invention/champions an idea within the organization;
Bapu saw a business opportunity in the retro-styling of the speaker;
Promoting the product through online platforms/broadcasts/interviews;

Award [1] for each distinct point in an explanation of Pavan Bapu’s role as entrepreneur and product champion in the success of the Gramovox^® bluetooth speaker up to [3 max].

Mark as [3] + [3].

(Answer in brackets not required for the mark.)

Freehand sketches:
Rough drawings/sketches used to convey/communicate an idea;
In a quick/easy/cost effective way;
To record/improve ideas as idea development progresses;

Physical models:
The creation of a (smaller or larger) tangible version of an object (that can be physically interacted with);
To test/evaluate the aesthetic/function/performance;
And provide feedback that enables the designer to modify/improve the speaker;

Solid models:
Provides a complete set of data for the product to be realised;
Used for simulations/feedback (of the assembly/materials/performance of the speaker);
Saving on time/labour (without the need of a physical model);

Award [1] for each distinct point in an explanation of the benefit of using freehand sketches, physical models and CAD solid models in the development of the horn of the Gramovox^® bluetooth speaker up to [3 max].

Do not award marks between clusters.

Mark as [3] + [3] + [3].

(Answer in brackets not required for the mark.)

Not well answered. Very few achieved 2 marks. Some got 1. Most did not get density.

A nice question, generally well answered with many candidates able to achieve 2 marks. Some were able to achieve 3 marks.

An easy enough question, well answered by some candidates only. Almost all candidates could pick up 1-2 marks but not many got more than 4. The last point in the entrepreneur cluster was not addressed by many candidates, neither was the middle point in the product champion cluster. Quite a few mentioned the entrepreneur as a ‘risk taker’ and ‘provider of finance’.

This was the most accessible of the 9 mark questions which made it easy for students to pick up 2-3 marks in both the freehand sketches and physical models clusters. Solid modelling was not quite as well answered, but some picked 1 or 2 marks here also. Overall, most students I marked achieved 4-7 marks for this question overall.
