1. Demand Analysis and Concept Generation
The first step in the design of Home Appliance Prototype Parts is to conduct demand analysis, which is the basis for moving from concept to function realization. The design team must first have a deep understanding of the overall functional requirements of home appliances, including user expectations, market trends, and product positioning. For example, for a new smart refrigerator, market research may show that users want more precise temperature control, larger storage space, and convenient smart interconnection functions. Based on these needs, designers begin to conceive the concept of parts. For example, for precise temperature control, they may think of designing a new temperature sensor part concept. This concept may initially be just a general functional description, such as being able to quickly and accurately sense temperature changes in a small space.
2. Principle Research and Technology Selection
After having a preliminary concept, principle research and technology selection are needed to promote the transformation to functional realization. Taking the temperature sensor as an example, designers need to study different temperature sensing principles, such as the working mechanism, advantages and disadvantages of thermistors, thermocouples, etc. Then, according to the specific requirements of the refrigerator, such as measurement range, accuracy, response speed, etc., select the most suitable technology. At the same time, it is also necessary to consider the collaborative working principle with other parts, such as how the sensor interacts with the refrigerator's control system to ensure the realization of the temperature regulation function. This stage may involve consulting a large amount of technical information, conducting theoretical calculations, and laboratory verification of some key technologies to determine the technical direction for part design.
3. Detailed design and modeling
After determining the technical direction, enter the detailed design and modeling stage. Designers begin to carry out detailed structural design of Home Appliance Prototype Parts based on the selected technology and principles. For temperature sensors, this includes determining their external dimensions, shell materials, internal circuit layout, etc. At the same time, computer-aided design (CAD) software is used to build a three-dimensional model of the part, and each detail is accurately constructed in the model, such as the connection method of the pins, the installation position of the sensor element, etc. This three-dimensional model should not only reflect the appearance and shape of the part, but also accurately reflect the structural relationship of its functional realization. In this process, designers need to consider the feasibility of the manufacturing process. For example, some complex shapes may require special manufacturing processes to achieve, which requires trade-offs and adjustments during design to ensure that the designed parts can be actually manufactured and meet the functional requirements.
4. Prototype production and functional verification
The last step is the prototype production and functional verification link. According to the designed model, the physical object of Home Appliance Prototype Parts is produced through various manufacturing methods. For temperature sensors, precision machining or electronic manufacturing processes may be used to produce samples. The prototype parts are then installed on the actual home appliance test platform (such as a refrigerator prototype) for functional verification. In this process, various test equipment are used to detect whether the parts meet the expected functional indicators, such as using a high-precision thermometer to verify whether the measurement accuracy of the temperature sensor meets the design requirements. If problems are found in the functional verification, such as excessive measurement errors or insufficient response speed, the design needs to be adjusted, the prototype needs to be remade and verified again until the part can fully realize the functions set from the concept.
