The initial section of this one-day program provides problem identification, validation, and creative tools for solving the problem by an individual. The goal for the entire training program is for the participants to learn and integrate effective tools for identifying and solving BIPs individually, but especially with a team. Team problem solving is useful if there is a deadline or time pressure.
- See a Problem?.
- Effective Leadership.
- Embrace Change Or Get Left Behind?
The training will deepen problem solving skills and translate to improved productivity and often previously unrecognized pathways to business success. Basic tools for validating and assessing BIPs will be taught and used. Other aspects will include:.
Dragonfly Thinking: Problem Solving for a Successful Future by Bruce Oberhardt
In this section, you will learn how to organize an effective team to understand and solve problems in the workplace and for customers. Your team will take on a real problem that was identified in the first section, coming up with ways to understand it more fully and to solve it.
Determining how to implement the best solution from Section Two with available resources and understanding how to fully integrate Dragonfly Thinking as a regular practice with your team. Dragonfly Thinking will enable you to deal effectively with conflict and challenges that often emerge when interacting with others in a company or organization and help you to generate innovative solutions to business problems, as well as to make your own life more interesting!
Obata found that the dragonfly's wing structure held the key to its stable flight. Specifically, it was the fact that its very thin wings, with their corrugated surface, created a series of small vortices above the wing surface while in flight. This was the secret to allowing the wings to create lift by making the vortices flow backward, like on a conveyor belt, and simultaneously reducing air resistance by also sweeping backward any air that is trying to "cling" to the wing. Based on this research he succeeded in developing a micro-sized flying robot using the dragonfly's wing structure and flight mechanism as an inspiration, but one day one of his friends asked him, "So, can you actually create anything useful with this robot design?
He replied, "That's a good point.
Solving the Problem of Nature’s Drone
I will invent something useful using the technologies learned from the dragonfly. The dragonfly is good at maintaining stable flight even in a slight breeze, So he wondered if he could make use of this ability to keep stable at low speeds as a nature-based technology, taking the opposite of the approach usually followed by industrial society in pursuing high speed and high power. Later on, he came up with the idea of applying the technology to the blades of wind turbines, and after three to four years of trial and error he created the micro wind turbine.
Most large-scale wind turbines in Japan have a mechanism that rotates only with the wind blowing from the same direction at a constant speed, like the ones used in Europe. These turbines do not rotate in light winds, so they are not so suitable for Japan where winds vary dramatically in strength and direction. In fact, this micro wind turbine rotates even when it catches a slight breeze as light as 30 centimeters per second about 1 kilometer per hour , even with a generator attached.
It also costs a large amount of money to construct sturdy wind turbine structures that can withstand gale force winds such as typhoons. In high winds, the turbine blades curve into a conical shape -- instead of rotating faster -- to adjust to the wind, and this lowers the electricity output automatically.
The micro wind turbine can tolerate high winds because of its ability to avoid damage by adjusting its shape, and yet can continue rotating even in a slight breeze, so it is better suited to the variety of wind conditions in Japan. Many wind turbines in Japan generate electricity using blades that rotate at a high speed to turn a shaft connected to a generator. In contrast, the micro wind turbine rotates efficiently at low speed, and do not make any low-frequency noise, one of the problems with large-scale wind turbines. At the same time, thin plastic plates or even cardboard can be used for micro turbine blades, as well, making it safe for someone to even stop the spinning blades by hand.

Micro wind turbines have many possible applications. For instance, in developed countries they can be used to generate basic household electricity -- at least enough to charge cell phones and batteries -- by installing them on the balconies of apartment buildings. Whereas in countries where blackouts often occur, they can supply basic electricity demands, such as for lighting at night, without the need to construct large-scale power plants or expanding power grids. Obata intends to conduct more research toward the design's practical use for supplying electricity safely and inexpensively in rural areas.
His research laboratory has two objectives for achieving the practical use and promotion of the micro wind turbine. The first is to achieve a constant output of electricity amounting to up to 20 percent of the actual power of the wind. Although there are challenges getting actual electricity output from a generator, an output of between 15 and 20 percent appears achievable at this time with the speed of 2. However, if the developers can attain high rotation under the average wind speed and an electrical output of nearly 30 percent of the power of the wind under various conditions on electric loads on the generator, this new invention could be the perfect compact wind turbine, usable by anyone.
Obata says, "I want to review the theory of the wind turbine right from square one, and achieve 30 percent output by combining the latest electricity generation technologies. Another challenge is production cost.
This wind turbine is produced in small numbers at the moment, as the manufacturing process requires time and efforts. When considering mass production, the labor cost could be expensive. Thus, there is no option but to produce it in developing countries with lower labor costs, although, it may be a challenge to maintain high quality and product performance. He still hopes to be able to manufacture the turbines while maintaining high quality at a low cost, even in a country like Japan where labor cost is high, and estimates the manufacturing cost per unit could be kept as low as 10, yen around U.
At the end of our interview we asked Prof. Obata for his current thoughts and what he wants to pass on to the younger generation regarding the key philosophy of learning from nature, looking back at his past studies -- specifically when he started to observe dragonflies, then develop a flying robot, and finally created the micro wind turbine. Reflecting on his past research and inventions, he answered, "Certainly, research based on field work to study nature is important.
