Linear Design Process
Design is the conception of an idea and its development, through graphic communication, into a practical, producible, and usable product or process.
Functional design is the design of a product so that it operates successfully or accomplishes its purpose.
Aesthetic design is the form or overall physical appearance of the product. Aesthetics involves characteristics such as color, line, style, space, contrast, proportion and balance.
In the development of the any product, designers use knowledge, creativity, experience, and resources to create a new or improved product. The design must be functionally efficient, meet the design objective, and be aesthetically appealing.
In the linear design process, a designer takes the design of a product from the initial design problem or idea stage and carries it through, step by step, until it is turned over to the production division.
1. A design or idea starts with the recognition of a problem or the determination of a need or want. The designer carefully analyzes the idea to determine
if it is practical and marketable.
2. Next, alternative designs are gathered to create possible product solutions. All notes and sketches are signed, dated, and retained for further work and
possible patent proof.
3. At this point the best solution is evaluated in detail, and attempts are made to simplify the design so that it performs efficiently and is easily
manufactured. Materials and costs are carefully considered. A design layout drawing is made to show basic proportions of parts and how they fit
together in an assembly drawing.
4. After the most feasible solution is selected, a prototype is constructed to test the design. The prototype can be a physical model or a computer-
generated model of the design.
5. Once the engineering team or a select group of consumers has evaluated the prototype, the feedback is used for changes to the design. The design
process then loops back to previous stages for final consideration before the manufacturing of the product.
6. Finally, a set of working drawings are prepared, and the design is sent into production.
