Open Innovation from Japan

An idea regarding agricultural materials that are widely used. By using biodegradable materials, we can reduce processing costs while improving workability. If realized, it could lead to a significant transformation in agriculture. Evaluation: 4.4.

Consideration of mixed farming methods utilizing the characteristics of the residential area, including crops like coffee, wasabi, and fruits. Simultaneously examining the structure and systems of robots for job hunting. Evaluation: 4.0. This is something rare that I am doing myself, to try it out. I am currently taking a course to start agriculture. However, since it is for agricultural management, whether I will start farming myself is a separate issue.

Application of mist generation mechanisms to coatings. In particular, a configuration specialized for narrow spaces such as pipes. Evaluation: 4.2.
I thought I had improved it myself, but the evaluation turned out to be low. Interesting, isn't it?

Mist generation mechanism. There is a possibility it can also be used for painting. If used for painting, it should be at low pressure. There is also a possibility of significantly reducing the amount of paint used. Rating: 4.3.

Simultaneous heat storage and cooling system. Since July 4th. It has not received a rating of over 4.0 at any time. This is the second example. Initially, it was only a heat transfer system using PCM. Although the evaluation of ChatGPT is groundbreaking, relying solely on technology leads to an overall low rating; as a result, we considered the product, its uses, and applications, and achieved a rating of over 4.0 through that total.

Initial costs range from $200 to $400, with almost zero operational costs. There is a high demand in developing countries and disaster-affected areas, and an ROI of 2 to 3 years is quite attractive. It directly contributes to food waste reduction, medical cooling, and disaster support. Creating employment and reducing environmental impact also provide significant social value.

Disaster and Non-Electrified CPAP / Auxiliary Breathing Device Concept for Developing AreasUtilizing the motor structure devised the other day.At the same time, devising a CPAP system that does not use electricity at all at night.Evaluation: 4.2.

The structure is simple and can be made with commercially available parts. Reliability testing of safety valves and pressure control is key.It is effective as an alternative to CPAP in disaster or power outage environments. However, comfort verification during long-term use is necessary.It is easy to deploy on-site and has low training costs. Optimization in terms of weight, size, and hygiene management is needed in the future.

A technology that separates air into nitrogen, oxygen, and carbon dioxide with low energy. Rating: 4.2.

The fact that it does not require external power for cooling is revolutionary. It is sustainable in that it does not require large-scale cooling equipment and can ensure low-temperature environments through natural phenomena.

Disaster medical care, agriculture, food preservation, and infrastructure in developing countries have a wide range of demand. The device configuration can also be simplified, allowing for mass production.

Artificial heart unit utilizing a motor creatively designed by nature. To be used as a backup for the original heart, or in the femoral artery. Evaluation, 4.2.

With a unique configuration that distinguishes it from existing LVADs and TAHs, including features such as decentralized electromagnetic control, pulsation control, heparin release, and micro-vibration, particularly the clear differentiation of 'femoral artery attachment' and 'reduction of stroke risk through pulsation reduction'. Although competitors exist, there is an advantage due to the focused patent strategy.

It is designed with a high degree of patentability and a configuration (materials and methods) that allows for concrete prototyping. The realistic implementation roadmap is also clear, involving prototype→simulation circulation tests→animal experiments. However, obtaining certification for medical devices requires a medium- to long-term strategy, and securing funding and partnerships remains a challenge.

1. Flexible propulsion mechanism
   Designed with applications for aerial and underwater drones in mind, this provides a noiseless and safe propulsion method without the need for propellers. It supports hybrid operation with fixed and movable wings, aiming for energy efficiency and environmental harmony.
2. Miniaturizable actuator and motor structure
   Developed as the driving unit for the propulsion mechanism mentioned above, it is quiet, vibration-free, and produces strong torque. Two types were devised: one with a flat design and another incorporating a rotational axis.
   

Idea from August 6, 2025 – Entry ① Rating: 4.5 Concept: A scalable heat pipe design that minimizes the risk of flooding phenomena.

Idea from August 6, 2025 – Entry ② Rating: 4.7 Concept: A fluid control mechanism and optional module concept for compressors.

① If successfully scaled up, this heat pipe concept could potentially be applied to large-scale systems such as thermal power plants.

② If realized, this fluid control concept might become a milestone in the history of fluid dynamics. It enables distributed fluid control systems and consists of two types: one related to liquid surface control, and another concerning pipes and hoses.
