Technology Topic 1: The Design Process

Annotating freehand drawings is important to explain the thinking behind the visual images. By adding annotations, the creator can provide additional context, explanations, and details about the drawing, allowing others to understand the thought process and intentions behind it. This helps in effectively communicating ideas, conveying information, and ensuring that the message is accurately interpreted by others.

During the stage of generating ideas in the design cycle model, drawings are most likely made without using technical aids. This is because at this stage, designers are focused on brainstorming and exploring various concepts and possibilities. They may sketch rough drawings to visually represent their ideas and communicate them to others, but these drawings are not meant to be detailed or precise. Technical aids, such as computer-aided design (CAD) software or drafting tools, are typically used in later stages when the final solution is being developed and refined.

Definition: Incremental - Small changes to the design of a product that seem trivial but the cumulative effect over a longer period can be very significant.

The product specification justifies the precise requirements of a product. The specification will
include a full list of the criteria against which the
specification can be evaluated.

Designers use perspective drawings to realistically represent an object. Perspective drawings allow designers to accurately depict the three-dimensional qualities of an object on a two-dimensional surface. By using techniques such as vanishing points and foreshortening, designers can create a sense of depth and spatial relationships, making the object appear as it would in real life. This helps viewers understand the proportions, scale, and overall appearance of the object, aiding in the design process and communication with clients or stakeholders.

The given statement "low capital cost" does not describe an advantage of using computer aided design (CAD). CAD systems typically require a significant investment in hardware, software, and training, making the capital cost relatively high. However, CAD offers advantages such as the ability to interface with other computerized systems, ease of storage for designs, and a reduction in the time taken to update engineering drawings.

Detailed orthographic drawings are best used to show the dimensions of a finished product for manufacturing. Orthographic drawings provide accurate and detailed information about the size, shape, and measurements of a product. This allows manufacturers to understand the exact dimensions and specifications required to produce the product accurately. These drawings are essential in ensuring that the manufacturing process is precise and that the final product meets the desired specifications. They provide a clear representation of the product's dimensions, enabling manufacturers to create the product with accuracy and precision.

Radical design refers to the inclusion of new material or technology that brings about a significant change to the design. This term implies a complete departure from existing design practices and the adoption of innovative and transformative elements. It suggests a disruptive and revolutionary approach to design, resulting in a substantial shift in the overall concept and functionality of the product or system. Incremental design, on the other hand, involves small, gradual improvements or modifications, while green design focuses on environmentally friendly practices, and clean technology pertains to the use of clean energy sources.

The precise limits for a complete range of performance requirements will be stated in the Product Design Specification (PDS)

A designer is most likely to use an orthographic drawing in discussions with a manufacturer. Orthographic drawings provide a detailed and accurate representation of an object from multiple views, allowing the manufacturer to understand the dimensions, shape, and features of the design. This type of drawing is commonly used in engineering and manufacturing industries to communicate design specifications and ensure accurate production.

Definition: Adaptation - A solution to a problem in one field is used to provide a new idea for a design problem in another.

Constructive discontent is the most likely factor to result in changes to the design of an existing product. This term refers to a state of dissatisfaction or dissatisfaction with the current design, which motivates individuals to identify areas for improvement and suggest modifications. By recognizing the limitations or flaws in the existing design, individuals can generate new ideas and propose changes that can enhance the product's functionality, efficiency, or aesthetics. Therefore, constructive discontent is a driving force for innovation and improvement in product design.

A performance test is designed to measure and evaluate the performance of a system or product. It aims to provide objective and measurable data regarding the system's speed, efficiency, responsiveness, and other quantitative metrics. This data is crucial in determining the system's performance capabilities and identifying any potential bottlenecks or areas for improvement. Aesthetics data, qualitative data, and data about users' opinions are not typically the main focus of a performance test, as they are subjective and not directly related to the system's performance.

In the planning and realizing stage of the design cycle model, detailed costings of a product are best made. This is because during this stage, the chosen solution has been developed and finalized, allowing for a more accurate assessment of the costs involved in bringing the product to market. Additionally, this stage involves creating a detailed plan for the production and implementation of the chosen solution, which requires a thorough understanding of the associated costs. Therefore, planning and realizing the chosen solution is the most appropriate stage for conducting detailed costings of a product.

In the design cycle, the final design solution is evaluated against the requirements set out in the specification. This means that after going through the various stages of the design cycle, such as exploring ideas, receiving feedback, and revisiting certain elements multiple times, the final design solution is assessed to determine if it meets the specified requirements. This evaluation ensures that the design solution aligns with the initial goals and objectives outlined in the specification.

Constructive discontent is defined as analyzing a situation that would benefit from redesign and developing a strategy to improve it. This involves identifying areas that need improvement and actively seeking ways to make positive changes. It is a mindset that encourages individuals to question the status quo and find innovative solutions to problems. By embracing constructive discontent, individuals can drive progress and create a better future.

Orthographic drawings are most relevant in the stage of planning and realizing the chosen solution. This is because orthographic drawings provide detailed and accurate representations of the object from multiple views, such as top, front, and side views. These drawings are essential in the planning phase as they help in visualizing the final product, understanding its dimensions, and ensuring that all the necessary components fit together properly. Additionally, orthographic drawings are also useful during the realization stage as they serve as a reference for manufacturing and assembly processes, ensuring that the final product is built accurately according to the design.

Planning and realising the chosen solution is the stage of the design cycle model that is most likely to involve mathematical models. This stage involves creating detailed plans and specifications for the chosen solution, as well as implementing and testing the solution. Mathematical models are often used during this stage to analyze and optimize the design, calculate dimensions and quantities, and simulate the behavior of the solution.

Physical models and mathematical models represent selected features of a design. This means that they focus on specific aspects or elements of a design rather than attempting to replicate the entire design. By representing selected features, these models provide a simplified and focused representation that can be used to analyze and understand those specific aspects. This allows clients and designers to gain insights and make informed decisions about the design without being overwhelmed by unnecessary details. The other options provided, such as being easy to understand by clients, being 3D, or being realistic representations, are not necessarily true for all physical and mathematical models.
