Design specification for Bobble Bottle

1. Function The bottle needs to hold water without any leakages. It also needs to filter the water as the consumer is using it as this is what is advertised.

2. Materials The bottle is made from PET which is BPA and phthalate free. The filter housing is made from PP which is also BPA and phthalate free. These materials are cheap to manufacture and also easily mouldable when heated.

3. Size and weight The bottle is very light as the weight will increase when liquid is added. The bottle also comes in a variety of sizes ranging from small enough to fit in a pocket up to a 1L bottle.

4. Durability The bottle is very durable as it is made from strong materials. It also has a protective coating to prevent scratching. There is no possibility of cracking due to the nature of the plastic.

5. Manufacture The bottle is blow moulded which leaves no visible manufacture marks. As all the bottles are the same, they are made using mass production techniques.

6. Safety The bottle has no sharp edges are areas which could harm a small child. There are also no small parts. This means that the bottle can be used by all ages.

7. Quality The product is checked for quality as it runs through the production line. Due to the mass production the quality is very accurate and consistent.

8. Ergonomics The bottle has an indent in the side which means it is very easy to grip. Additionally the lid is made from a rougher material meaning it is easy to open.

9. Cost The small bottle costs £10.49 and the larger bottle costs £12.99.

10. Aesthetics The water bottle has a very minimalist style with the design coming from the shape of the bottle and the colour of the lid. The clear bottle create a simplistic aesthetic.

11. Maintenance The bottle requires very minimal maintenance with exception of cleaning after use. However if the filter seems to stop working, there are filters available on the website which can easily replace the old one.
