Embedded system design refers to the process of integrating a specially designed computer system (hardware and software) into a specific device or system to perform particular functions or tasks. These systems are typically embedded into other products or systems as essential control and processing components, rather than functioning as standalone computer systems. Embedded system design involves hardware design, software design, and system integration, aiming to achieve efficient, stable, and reliable system functionality.
Six Fundamental Principles of Electronic Product Design
User Experience Design

Exterior design directly influences the market image and user appeal of a product, considering factors such as aesthetics, ergonomics, and manufacturing processes. Designers need to create an exterior style that aligns with current trends and brand image based on the product’s positioning and the aesthetic preferences of the target users.
Cost Control
In the product design process, careful consideration of manufacturing costs and material costs is necessary to ensure the product’s price competitiveness. Cost control involves selecting materials, optimizing manufacturing processes, and improving production efficiency.
Technological Feasibility
When designing product functions and performance, technological feasibility and implementation difficulty must be considered. Designers need to understand current technological levels and industry trends, choose suitable technical solutions, and ensure that the product design complies with existing technical standards and specifications.
Reliability and Safety
Product reliability and safety are crucial design indicators directly related to user safety and product brand reputation. Designers need to consider various potential risks and safety hazards during the product design process and adopt corresponding measures and technical means to ensure product reliability and safety.
