what are intellectual property rights
intellectual property rights are ideas, designs and other non-physical property. you protect your ideas because someone could steal them and take the profit.
why do we need ip
why we need I.P:
- consumers-protects the quality means it is the real thing
- designers, inventors, and entrepreneurs ,
- society and the economy- allows business to grow
what is a patent
-patents - can only be used in certain instances- it gives monopoly (total control) of the rights to the exclusive use and production of an invention, can last for a max of 20 years- gives the owner sold right.
what is design registration
-Design registration- Protects only visual apreances of the object- can last up to 5 years in inertial apicalican, can renew it up to 25 years- induces the shape, configutstion of a 3D design and the pattern ornament of a 2D design (logo), example for exam is apple vs samson.
what are design rights
Design right has the same rights and registration but only for 2D- las up for 10 years and its fast cheap, often used for textiles.
what is trademark
Tradmark- Any sign, logo, brand image which can be represented graphically (cadubury purple)- includes company names and branding for goods and services- also includes personal names, designs, induvidul letters (bbc ) and shape of goods and packing (coke bottles) - registered for 10 years and can be renewed for infinity.
what is copyright
Copyright- protects original written, dramatic, musical and artistic work, including web sites- copy right is an automatic process (you can copytighy your DT work, just name, date and add- its reconised world wild- last for 70 years after the death of the creator.
what do you need to mention for all rights?
use this for all the RIGHTS!!- with the I.P the item becomes a property which can be bought, sold, hied or lisanced to others.

Describe two key properties of a named natural material and two key properties of a named synthetic material. 2 x [2]
Identify a specific product where one of these materials has been used and explain why the material was chosen.
Natural materials – ‘obtained or made from living things’.
Examples include cotton, paper, silk and wool, gold, silver, latex, cottons, natural cellulose.
Silk is the strongest natural textile fibre but loses some of this strength when wet.
The high tensile strength of silk is due to the many bonds in its construction, and when stretched the force is applied to these numerous bonds and they do not break.
Synthetic materials – ‘made from chemicals’.
Examples include nylon, polyester, polyurethanes, acrylic, polyester mix textiles, synthetic fibres, cement, and concrete.
The mechanical properties of nylon include high strength-to-weight ratio, high breaking elongation and excellent recovery from deformation.
Nylon’s properties, when used in carpet manufacture appearance retention, because of abrasion resistance; texture retention; recovery from crushing; durability; and dye fastness.
quantitative and qualitative testing are important aspects to consider when selecting a material or materials for a specific product.
Explain what you understand by each of these terms.
Quantitative testing is objective, measurable criteria, which can be assessed against specific performance measurable objectives.
Marks allocated with a full description with any of the following examples up to a maximum of 4 marks:
The material must weigh no more than ……
The material used must be light enough to ……
Other examples related to material hardness, malleability, ductility. 4 marks Qualitative testing will reflect the intended quality of certain defined aspects of a
material’s specification. It is a more subjective form of criteria.
Marks allocated with a full description with any of the following examples up to a maximum of 4 marks:
The material must be aesthetically pleasing.
Material used must be recyclable.
The material must be bright.
A production plan consists of important stages in the manufacture of a product.
Describe four main elements of a production plan for a product of your choice.
The 4 major elements to include: A specification for manufacturing the product. Use of detailed drawings/computer aided design (CAD). Working out the schedule for making. The tools to be used. Time for each operation. Safety and quality checks. The cost of production and profit. Setting targets and deadlines.
Design specifications are used by designers to identify key criteria in the development of new products.
(a) Describe the important features of a design specification. 2 marks
(b) For a named product, list three primary specification criteria and three secondary specification criteria.
Design Specification – A product design specification is a statement of what a not- yet-designed product is intended to do. Its aim is to ensure that the subsequent design and development of a product meets the needs of the user. The aim of the product, how is it to achieve its purpose, the target market, ergonomic factors, appearance and finish – aesthetic considerations.
Primary (the key essential elements)
Product: Reading Lamp
1. The material selected must be from a sustainable source and display this information to the consumer.
2. The weight of the unit must not exceed a total weight of 2kg.
3. The individual components must be easily removed for replacement purposes.
Secondary (the additional elements or features)
1. The unit is available in a range of colours.
2. The unit will include a range of different materials in its construction.
3. The unit can be used in a variety of environments.
Responses may also refer to manufacturing specification (for a named product) – quality and safety, quantity to manufacture (will affect any tooling or moulding requirements).
The design and manufacture of products can involve the use of ICT.
Illustrate how ICT is used for research, modelling, prototyping and manufacturing.
Research
Using the internet, specific search engines, and collation of data in research to aid designing.
(b) Modelling
Compute aided modelling and using specific programmes to produced models. Communication of modelled ideas via the web to other locations.
(c) Prototyping
The use of rapid prototyping machines and how this benefits the whole process before manufacture.
(d) Manufacturing
The use of CAD and CAM systems during manufacturing. The use of computers to control and production line and monitor progress
Bought-in or standardised part-assembled components are used by manufacturers in the production of products.
(i) Explain what is meant by bought-in or standardised part-assembled components. 4 marks
(ii) State two advantages to the manufacturer of using bought-in or standardised part-assembled components.
Definition of term 4 marks
Components that are standardised can be substituted one for another i.e. using the same threat, fixings etc. These can be sourced from other companies and bought in making it possible to complete products very quickly.
Buying in means that the main company can specialise in its core operations, leaving other companies to take responsibility for the quality of a bought in component.
(b) Advantages
Aspects of quality previously checked and signed off (the responsibility for quality lies with the other supplier). Consistent quality is maintained.
Components may be produced by a specialist manufacturer from another location, allowing the main manufacturer to concentrate on assembly.
Lower costs from buying in bulk and investment possible elsewhere within the manufacturing process allowing for flexibility (the ability to shop around for lower costs).
Describe the features and benefits of the following Intellectual Property rights to the owner.
(a) Copyright
(b) Registered Trade Mark
Features and benefits Copyright
- Literary works, including novels, instruction manuals, computer programs, song lyrics, newspaper articles and some types of database.
- Dramatic works, including dance or mime.
- Musical works.
- Artistic works, including paintings, engravings, photographs, sculptures, collages,
architecture, technical drawings, diagrams, maps and logos. - Layouts or typographical arrangements used to publish a work, for a book for instance.

Benefits the copyright owner in that
Another person should only copy or use a work protected by copyright with the
copyright owner’s permission.
Copyright applies to any medium - this includes, publishing photographs on the
internet, making a sound recording of a book, a painting of a photograph and so on. Copyright does not protect ideas for a work. It is only when the work itself is fixed, for example in writing, that copyright automatically protects it - you do not have to apply for copyright.
Features and benefits: Registered Trade Mark 4 marks
Any sign which can be represented graphically.
Any sign which can distinguish goods or services.
Includes words, personal names, designs, letters and the shape of goods and their
packaging.
Registered for 10 years and can be renewed every 10 years indefinitely.
Concurrent engineering is a process used in the manufacture of products.
(a) Explain what you understand by concurrent engineering. 4 marks
(b) State two advantages of concurrent engineering to the designer and manufacturer.
Concurrent Engineering is a systematic approach to the integrated, concurrent design of products and their related processes.
2. This includes manufacturing and support and is intended to cause the developers from the very outset to consider all elements of the product life cycle, from conception to disposal, including cost, schedule, quality and user requirements.
3. It is different than the traditional product development approach in that it employs simultaneous, to rather than sequential processes.
Up to 4 marks for explanation
Advantages
Completing tasks in parallel, product development can be accomplished more efficiently and at a substantial cost savings.
Rather than completing all physical manufacturing of a prototype prior to performing any testing, concurrent engineering allows for design and analysis to occur at the same time, and multiple times, prior to actual deployment.
Multidisciplinary approach emphasizes teamwork through and it allows for employees to work collaboratively on all aspects of a project from start to finish.
