The inherent technology of computerized sewing machine products is closely tied to addressing key aspects such as seamability, functional requirements, operability, reliability, and durability. It involves the continuous advancement of the product’s own technology, aiming for high-speed performance and automation. Technical solutions like specialization and integration are concerned with the methods and strategies used to implement these innovations. These elements collectively form the core technical knowledge of computerized sewing machines.
Mastering the core technology of industrial computerized pattern machines requires deep professional expertise, including knowledge from related fields. Only by thoroughly analyzing and mastering the essential technologies can we develop and design products with independent intellectual property rights. Through continuous technical accumulation, we can gradually build a product design database and a mechanism map for sewing machines, laying a solid foundation for future innovation in industrial sewing machine design.
It is important to note that the core technology of sewing machine products is not static—it evolves with the maturation of existing technologies, the introduction of new technologies, product upgrades, function expansions, and even the creation of new stitch types. While specific technologies may change, many common principles remain applicable across different products, especially when developing a series of related products. This highlights the significance of technological accumulation and practical experience.
For example, high-speed lockstitch machines require mastery of several key technologies, such as:
1. Lightweight technology: including analysis of vibration sources, use of lightweight materials, and understanding the impact of casing cross-sections on vibration.
2. Factors affecting low-tension sewing.
3. Upper thread dynamic tension measurement techniques.
4. Rotary hook design.
The industrial computerized sewing machine industry has established standard line types. The basic mechanisms that produce various stitches have been refined over time, and their designs tend to stabilize. Product improvements, variety expansion, and technological upgrades are typically based on existing models. The integration of mechatronics provides more opportunities for gradual innovation, but it still relies on the original structure, adding automation or system functions. It is unlikely that the fundamental types of industrial sewing machines will be completely replaced. Even if cam mechanisms are replaced by electronic control systems, it's just a shift in control mode aimed at simplifying the mechanism.
Reverse engineering is also an innovative approach. It involves a comprehensive, in-depth, and systematic analysis of advanced existing products using scientific testing methods. Understanding the structural features, mechanism principles, functionality, quality level, and design parameters of the product is crucial. At the same time, evaluating new technologies, processes, and materials applied in the product helps identify areas for improvement and user needs. This serves as a starting point for innovative design.
Market demand drives the development of any sewing machine product. The guiding principle is to align with the enterprise’s strategic goals and ensure the highest success rate. It involves assessing the marketability, economy, and quality of the product to meet diverse consumer needs.
Selecting a suitable prototype is essential for future product development. The chosen base product should be advanced, preferably from a well-known brand, and must meet user quality expectations. Establishing a product data (sample) library is also critical.
Evaluating the prototype includes checking its separability, functionality, durability, safety, and other key factors. Comparing the results with existing or advanced products helps define technical indicators for innovative design.
Examples of innovative solutions include rethinking feeding mechanisms, thread take-up systems, needle mechanisms, and transmission modes. Each innovation aims to improve efficiency, accuracy, and performance.
After evaluating the innovative design, clear improvement goals and technical requirements are set. Using the product data library, design database, institutional maps, and professional knowledge, a detailed design plan is developed. Physical prototypes are then tested, often requiring multiple revisions before reaching the optimal solution.
This process represents a comprehensive and practical approach to innovation. By embracing creative thinking, continuous learning, and experience sharing, our ability to innovate will steadily improve. This will significantly contribute to the progress of China’s sewing machine industry and help accelerate its position as the world’s leading producer.
