What is Conceptual Modelling?
- Conceptual modelling is the first step in realizing a design.
- Therefore conceptual design affects all of the following stages in the design process.
- Decisions made during the conceptual design stage will determine the fundamentals of the design project.
- Conceptual models are mostly a way for designers to straighten out their thinking before physically starting to design.
They can allow designers to explore a problem through mind mapping, brainstorming, discussion, conceptual sketching. - By fully understanding of the aspects of a problem, a designer can come to core concepts that need further investigation.
- This can distinguish good perspectives from bad ones in an early stage.
- Conceptual modelling is about getting your head around all the concepts involved in a design project.
- It allows you to frame and start to visualize the problem and (parts of) the solution by thoroughly (re-)assessing all aspects of the design brief.
- Different types of modelling can then be used to give shape to the concepts.
This can be done by using graphical, physical and virtual modelling. - The models one produces with these techniques, will be a visual and sometimes tangible translation of a concept, and therefore can also be called concept models, as they show an idea and are not the final product.
Elements of Conceptual Modelling
- A conceptual model originates in the mind and its primary purpose is to outline the principles, processes and basic functions of a design or system.
- Conceptual modeling describes a proposed system using models and concepts that define what it should do, how it should behave, and how it should appear.
- A conceptual model represents what the user is likely to think, and how the user is likely to respond. It is a high-level description of how a system is organized and operates.
- Conceptual modelling is essential for communication, and making the product understandable to users.
- A conceptual model includes all the information required to describe a potential design solution that simulates the physicality of the design.
- For example, functional features, performance and aesthetics.
- To be effective, conceptual models should be as simple as possible, incorporating concepts limited to those required for functionality.
- Conceptual modelling is also an iterative process and thus evolves and improves over time.
Purposes of Modelling
- Modeling is working out ideas or hypotheses by using sketching techniques to draw graphical or virtual models or by manipulating or printing materials to construct physical models.
- The chosen technique depends on the models purpose.
- Models can be made for all sorts of applications and purposes.
- It may be to show a proposed building design in its surroundings, or to show the form of a product for ergonomic considerations, or maybe to model a mechanism before manufacture.
- So the purpose determines the chosen modelling approach.
- For instance, designers of prestige cars may use a full-size clay model of a car at the final concept stage of the design process because at full-size it gives a more realistic view of the intended design and clay allows the shape to be changed easily, but at a considerable different cost level in terms of time, budget and technology.
Types of Modelling
- Conceptual modelling; A model that exists in the mind used to help us know and understand ideas.
- Sketches; Rough drawings of ideas used to convey or refine the idea.
- Graphical models; A visualization of an idea, often created on paper or through software, in two or three dimensions.
- Physical modelling; The creation of a smaller or larger tangible version of an object that can be physically interacted with. This may also include investigations into part of the design.
- Virtual prototyping; Photorealistic CAD-based interactive models that use surface and solid modelling. They can be considered 'digital mock-ups'.
