The starting point of product development is precise market insight. This stage requires identifying market gaps and user pain points through multi-dimensional market research. Data analysis should cover existing product sales data, user review analysis, social media discussion trends, and competitor product matrices. In-depth user interviews and focus group discussions can reveal users' unexpressed latent needs, particularly regarding user experience, privacy concerns, and emotional expectations.

The concept formation stage requires translating market insights into concrete product ideas. Creative workshops should involve cross-departmental teams, including designers, engineers, and marketing specialists, using design thinking methods to generate innovative concepts. Each concept needs feasibility assessment, including technical feasibility, production cost estimation, and market demand matching analysis. Typically, a mature product concept requires 3-5 rounds of iterative optimization before proceeding to the next stage.

The technical design stage requires transforming concepts into implementable technical solutions. Industrial design teams are responsible for product appearance, human-machine interaction, and user experience design, creating detailed 3D models and physical prototypes. Engineering development teams focus on internal structure design, electronic system integration, and software algorithm development. This stage requires special attention to product safety design, covering multiple dimensions including circuit safety, material safety, and mechanical safety.

Prototype creation and testing are key links in validating designs. Initial prototypes (Alpha prototypes) mainly verify basic functions and structural design, while intermediate prototypes (Beta prototypes) closely resemble final products for user experience testing and process validation. Each prototype requires rigorous testing, including functional testing, durability testing, environmental adaptability testing, and safety testing. Test data will provide important basis for design optimization.

Material selection directly affects product safety and user experience. The material selection process requires balancing multiple factors: medical-grade silicone must comply with ISO 10993 biocompatibility standards, electronic components need CE, FCC and other certifications, while packaging materials must balance protection and privacy. Material suppliers must provide complete testing reports and compliance certificates, accepting regular quality audits.

Supply chain construction requires consideration of all production aspects. Core component suppliers should possess stable quality control systems and sufficient production capacity, assembly factories need GMP-standard production environments, and logistics partners must provide reliable transportation services and privacy protection solutions. Supply chain flexibility and risk management are also key considerations at this stage.

Compliance certification is a necessary prerequisite for market entry. Different markets have varying certification requirements: the EU market needs CE certification and RoHS testing, the US market requires FDA registration and FCC certification, while other markets have their respective access requirements. The certification process typically takes 6-9 months, involving multiple stages including document preparation, sample testing, and factory audits.

Quality system establishment ensures product consistency and reliability. The quality management system should cover the entire process from raw material intake to finished product shipment, with key control points including incoming inspection, in-process inspection, and final inspection. Statistical Process Control (SPC) methods can monitor quality fluctuations during production, identifying and correcting issues promptly. A comprehensive traceability system enables rapid identification and resolution of quality problems.
