Research and Development
R&D
The Science of Comfort.
's Core Technology for Creating Spatial Value
Airflow control, germ elimination and deodorization, and auto-clean humidification.cadoWe are committed to researching and developing proprietary technologies that support a comfortable living environment.
Airflow Control Technology
Greater Control Over Air
Air, with even greater freedom. Designing air.
At the heart of this is the airflow technology from cado. Strong airflow, long-range airflow, and quiet operation—we are constantly refining the blade shapes and streamlined airflow paths that make these features possible. This minimalist design philosophy extends not only to the exterior but also to the internal structure. By combining blades with different characteristics and using specially designed blades and grilles, we engineer airflow tailored to specific applications.
Germ-Killing and Deodorizing Technology
Toward an Odor-Free Life.
Odors that constantly arise in daily life are a common issue that affects our comfort. In our pursuit of a system that continuously eliminates odors, we have developed a deodorization technology that combines a catalyst with ozone.
We harness the power of ozone and a mechanism that heats a catalyst to accelerate decomposition. We are developing Ozone Boost Technology, which breaks down odors at the molecular level, and Heat Refresh Technology.
Performance evaluations are conducted by an in-house development team composed of certified odor assessors. They quantify and evaluate the deodorizing effects based on subjective sensory perception.
Auto-Clean Humidification Technology
Let's make cleanliness even more commonplace.
To reduce the effort required to maintain humidifiers while ensuring both cleanliness and cost-effectiveness—this challenge sparked the development of AutoClean technology.
The idea was inspired by the concept of pasteurization, which is used for milk and other products. We developed a system that periodically heats the water in the tank to suppress bacterial growth.
By controlling the heating time required for disinfection, we maintain cleanliness while reducing power consumption. We are conducting research to use technology to simplify daily maintenance.
Research and Development of "
" Solutions for Organizing Daily Life
We actively collaborate with the medical community and external research institutions to conduct research and development on solutions that improve people’s daily lives.
Joint Research with Research Institutions
The Science of Sleep Quality.
While the effectiveness of futon dryers in combating dust mites has been proven in laboratory experiments, there have been no cases to date in which their effectiveness has been verified in real-world environments, where dust mites inhabit and reproduce in various parts of beds and futons.
cadoThe company conducted a field survey on the current state of dust mite control in real-world environments and tested the effectiveness of the FOEHN bedding dryer in those same environments, thereby identifying effective usage methods and verifying the product’s efficacy.
We will continue our research aimed at improving sleep and health.
Joint Development with Medical Institutions
Help people stay in good condition.
Through a collaboration between the medical and engineering fields, we are jointly developing a healthcare device based on tVNS (transcutaneous vagus nerve stimulation) theory to regulate the autonomic nervous system.
We have developed the world’s first patented technology that combines three types of stimulation—vibration, heat, and music—to provide a soothing experience for the ears and neck.
It delivers an unprecedented vibration sensation made possible by haptic feedback technology.
We are currently conducting clinical trials at university hospitals and specialized clinics, and are working to develop devices that address sleep-related issues and improve performance—in short, devices designed to optimize people’s overall well-being.
Strengthening Barriers to Entry for
Through Patent and Intellectual Property Strategies
Through proprietary technology and intellectual property strategies, we are building long-term competitive advantages and barriers to entry.
We have secured a basic patent for the technology that combines heating and ultrasonic methods—the core of our AutoClean humidification technology. Furthermore, we are working to obtain related patents covering the internal structure, thereby expanding the scope of protection for our proprietary technology.
- Basic Patent (Parent) No. 7847896 (Granted in June, Year 26)
- Basic Patents Related to Hybrid Technology Combining Heat-Based and Ultrasonic Methods
- Related Patents (Subordinate) Examination Request Pending
- Expanding the scope of protection for internal structures to deter imitation by competitors
We protect the airflow technology underlying the FOEHN series through basic patents and related patents. While we are pursuing patent protection with an eye toward derivative products, we are also leveraging this technology by licensing it to other companies.
- Basic Patent (Parent) No. 7546969 (Granted in July, Year 24)
- Comprehensive Coverage of the Basic Components of Stick-Type Futon Dryers
- Related Patents (Subordinate) No. 7729647 (Examined in August, Year 25)
- Expanding the scope of protection for exterior designs to strongly deter design imitation
- Enhanced Patent (Grandchild) JP 2025-147058 (Examination completed in June 26)
- Securing a broad scope of rights that takes future derivative products into account
