We will support the investigation of the causes of wire disconnection in hair dryers and hair irons, as well as improvement measures.
Hair dryers and hair irons have a high power consumption ranging from 1400W to 700W, which poses a risk of fire or smoke in the event of a malfunction, and there is also a high risk of injury to users. The National Consumer Affairs Center has reported on these dangers. (https://www.kokusen.go.jp/douga/20161208_1_news/n-20161208_1_low.html) The failure modes that can lead to serious accidents include: 1) Fracture of the power cord 2) Fracture of the internal wiring of bendable hair dryers 3) Fracture of the heater or breakage at the connection point between the heater and terminal. We will support the clarification of these failure causes and countermeasures. Additionally, we believe we can assist with issues such as the reproducibility of paint colors and cracks in resin.

basic information
The failure modes that can lead to serious accidents are: 1) Disconnection of the power cord 2) Disconnection of the internal wiring in flexible hair dryers 3) Disconnection of the heater or breakage at the connection point between the heater and the terminal The first failure mode, disconnection of the power cord, is related to the user's usage habits; however, manufacturers also need to consider this in their design. As society ages and the number of people living alone increases, the risk of fire rises. There is a demand for the development of safe and secure products. The second failure mode, disconnection of internal wiring, mainly occurs in flexible hair dryers. There is a gap at the bending point, which can cause sparks and poses a risk of burns. Knowledge of electrical wiring is necessary to resolve the first and second failure modes. I have experience in solving these issues from my background in a wire manufacturing company and my time at a beauty appliance manufacturer. The third failure mode, heater failure, usually sees deterioration at the connection point occurring first. Since the connection point can reach temperatures above 300°C, it is essential to investigate the causes of this failure mode and implement fundamental countermeasures. I developed a unique evaluation method to resolve this issue. If you are experiencing complaints or defects with hair dryers or hair straighteners, please feel free to consult with us.

Company information
The D&T Lab focuses on supporting research, development, design, and prototyping for manufacturing process engineering (design) and production technology development (technology). Particularly in the case of new businesses, it is necessary to introduce technologies that the company does not possess and to select and collaborate with partner companies. By utilizing so-called open innovation, we aim to shorten the marketing and product/service development periods, facilitate early entry into new fields and applications, and establish a unique strategy for the company using that information and technology to promote the business in earnest. Once we reach that stage, operations can be managed similarly to existing businesses. Therefore, the challenges of new ventures depend on how efficiently and effectively we design the entry stage. At that stage, it is necessary to gather information and technologies that the company does not possess and to make choices that are suitable for the company. I have experience in the development and launch of mass production equipment and the introduction of new products into factories. From the successes and failures I encountered, I have learned how to design mass production lines and introduce new products in my own way. Additionally, I possess processing techniques for various materials such as copper products, compound semiconductors, quartz glass, and plastics. I will contribute using the insights gained from these mass production technologies and material processing techniques.
