8. due to the fact that it would be extremely easy to use as it only involves the user inserting a uniquely shaped key into the barrel of the lock and pushing it to unlock the intended door It also has additional features which help insure that no unauthorised access can occur There are unique grooves placed upon the key and they would match up with bumps and grooves within the barrel of the lock This means that the lock will not open unless all of these grooves are in place Another added layer of security is that the plus key has a slightly longer edge on one of its points meaning that the key will only fit into the lock one way round This means that ifsomebody were to find the key they would then have to know about this additional security feature Also the locking mechanism has been designed to withstand any tampering and forced entry as when the door is locked the leaver mechanism is firmly locked in place This means that the harder you try to pull the more secure the lock will become think this is the products most appealing and interesting feature Ergonomics Ergonomics was not a large part of the design as most of the lock system is permanently situated within the door Yet my key is slightly ergonomic in the fact that is small enough to fit into the palm of your hand and is not to large that it would become an inconvenience to use It is also just the right size to fit in your hand easily when unlocking the lock Maintenance There would b

Cost The product must be made to a high standard however it must still be made of cheap enough materials for a suitable budget If my product ends up being created in mass use the materials must be cheaper so that it is easy to create and sell My product would be sold for 10 30 The ranges between these prices are high because the price of materials changes and the price from the manufactures creating the components will change over time as well as improvements of the technology within the product Testing A range of tests will needed to be carried out on the prototype to check that it is of a suitable standard This will test if my product stands up properly compared to the other locks within its target market Initially the tests will be based on safety checking that the electrics mechanisms and corners are finished to a high standard this will help to decide whether the product is safe to use Secondly functionality must be tested making sure its simple to use however effective at completing its job The final test will be a questionnaire to see if the lock is aesthetically pleasing Concept 1 people within the market Relative Authority to be Consulted In my project have to take into consideration the appropriate authorities before putting the locking system into production companies like the British Standards institute The lock must fit the guidelines of the BSI and will hopefully achieve the BSI kit

It must perform at a high enough standard to gain a good reputation by the people using it The locking mechanism must be strong enough to handle any forceful attempts of entry into the cupboard It also should only be able to only accept the unique combination card or key of the owner therefore the lock can t be tampered with Must be easy to lock and unlock when necessary minimising the time of the user For the product to be a success it should reach the demands of the public allowing the users products to be safe when using the locking mechanism Ergonomics Anthropometrics Locking mechanism must be the right size so that it can work well with the user small enough to be discrete and not take too much of the cupboard space however big enough to give access to the key easily If a handle is involved in the mechanism the handle must be comfortable in the users hand and fit the correct shape and size Maintenance Depending on the locking system it may need to be oiled on a regular basis to keep mechanisms moving smoothly and keeping the possibility of rust to a minimum if the product rusts it will also weaken the joints making it more liable to damage However this shouldn t be a major issue because the joints shouldn t be exposed If magnetic or electrical locks are being used the power source has to be considered If the lock is powered using an electrical main the fuse within the product may needed to be changed However if it s power

31. ll My product would be sold for 10 30 The ranges between these prices are high because the price of materials changes and the price from the manufactures creating the components will change over time as well as improvements of the technology within the product Testing A range of tests will needed to be carried out on the prototype to check that it is of a suitable standard This will test if my product stands up properly compared to the other locks within its target market Initially the tests will be based on safety checking that the electrics mechanisms and corners are finished to a high standard this will help to decide whether the product is safe to use Secondly functionality must be tested making sure its simple to use however effective at completing its job The final test will be a questionnaire to see if the lock is aesthetically pleasing aluation Materials Components The lock system will be made from high grade aluminium with a brushed finish helping it to fit in with the look and feel of most modern homes It also helps to increase the overall life soan of the product as the better the quality of materials used in the manufacture of a product the longer the overall life span of the product would help to increase the appeal of the product to potential customers who are wanting to use the product in there student housing Production This lock will be made using mass or batch production in an automated setting this would he
