“…Figure 10 shows one of the results of edge extraction using the cable operator. From the extraction results, it can be seen that the cable operator has a good effect on the simple image and the clothing edges are successfully extracted, but there are still some background spurious points in the image, so it can be seen that the edge extraction using only the cable operator cannot achieve the expected effect [36].…”

With the development of computer science, especially the application of 3D scanning technology in garment design, intelligent modeling is realized, which is impossible to achieve in traditional design methods. In this paper, we propose the 3D model construction of human garments based on the motion recovery structure method. The eigenmatrix is obtained from the camera parameters, and the transformation matrix is calculated by matching the image feature points with the help of scale-invariant feature conversion algorithm to realize the 3D reconstruction technology of human garments based on multiview image sequences. The effectiveness of this method is verified through experiments, and it has good robustness and accuracy. Through the form of style modeling, the design thinking and method can be extended to form a more reasonable garment structure and guide the innovation of garment production mode.

“…Detailed design phase includes specification of the physical appearance and materials of all parts in the product and the identification of all standard parts from suppliers. The output of this phase is full detail for the product such as the drawings or computer files describing the geometry of each part and its production requirement, the specifications of parts and raw materials, and manufacturing operation required to produce and assembly of the product (Wang, Yang, Hu, Huo, & Feng, 2021) (Zhang & Yu, 2016).…”

The design of a walking assistive device with a single stick, offset handle, and small base area platform has been introduced in this study as an alternative channel for supporting senior adults to walk by themselves with confidence while maintaining good posture. The stick can follow the rhythm of walking step, and the users can control it easily. To provide cost-effective design structure while preserving customer requirements, product design and development (PDD) with the assistance of finite element analysis (FEA) is applied in this study for simulating the load distribution on the area of interest. The perceptions from potential users expressed that “strong and stiff with light weight” were the main considerations for making a walking device. Aluminum material was suggested to be the reference for developing a walking cane. The concept of “usefulness of product” was applied as the guideline to help and support the design team for selecting the right design parameters of a walking cane based on the data obtained from the survey and customer perceptions.

“…In addition, when two existing systems need to interface in an application, REV helps ensure they can operate together. REV is also used for inspiration, personalization, and idea generation (Wang et al, 2021) and sometimes to ensure commercial advantage. Its methods and processes highlight two stages in the engineering design process: setting up experiments and determining design requirements, connected through communication (see Figure 2f).…”

Background: Understanding the nature of engineering is important for shaping engineering education, especially precollege education. While much research has established the pedagogical benefits of teaching engineering in kindergarten through 12th grade (K-12), the philosophical foundations of engineering remain under-examined.Purpose: This conceptual paper introduces the honeycomb of engineering framework, which offers an epistemologically justified theoretical position and a pedagogical lens that can be used to examine ways engineering concepts and practices are taught in precollege education.Scope/Method: The honeycomb of engineering was developed as a descriptive framework by examining existing literature over a wide range of related disciplines such as the philosophy of engineering and technology, as well as design thinking and practice. The pedagogical translation of the framework was then developed to examine published precollege engineering curricula. Results:The framework categorizes the multiple goals of engineering using an ontological classification of engineering inquiries anchored in the central practice of negotiating risks and benefits (i.e., trade-offs). This framework also illustrates the adaptability of design methodology in guiding six inquiries:(1) user-centered design, (2) design-build-test, (3) engineering science, (4) optimization, (5) engineering analysis, and (6) reverse engineering. The published curricula represented these inquiries with varying degrees, with design-buildtest lessons seeing the most representation followed by user-centered design. Conclusions:The honeycomb of engineering framework delineates variations in engineering education based on an epistemological explanation. The pedagogical translations offer guidance to educators, researchers, and curriculum designers for differentiating curricular aims and learning outcomes resulting from participation in different engineering inquiries.
