The Mitsubishi Electric Group engages in universal design under the principle of "creating user-friendly products and comfortable living environments that benefit as many people as possible." To achieve user-friendliness and comfortable living in the true sense of the words, we are committed to providing products and living environments that offer a high level of satisfaction to as many people as possible.
We have applied the concept of universal design (UD) to home appliances such as air conditioners and televisions, as well as to public equipment such as elevators, through considering the needs of all users. This approach is continuing to evolve.

Mitsubishi Electric has been ahead of the game in applying the concepts of universal design (UD) to home appliances. For instance, we have applied the Universal Design Guidelines to the RakuRaku-IH Cooking Heater cooking equipment.

Even in the industrial sector, where there is a high level of specialization and a relative lack of diversity in terms of operators who handle equipment, the labor environment is changing. Examples of this transformation include the aging of workers, and more foreign and inexperienced workers – changes that have increased the need for universal design. At Mitsubishi Electric, we are applying the concept of universal design (UD) in our industrial products, such as factory automation (FA) equipment and electric power devices, as well as to the installation and maintenance of equipment on factory floors.
We are also employing the Universal Design Guidelines for sequencers in FA equipment.

UD-Checker is Mitsubishi Electric’s proprietary tool that can be used by both industrial designers and engineers to evaluate for universal design (UD) qualities. This tool shows four quantitative measures of UD, namely recognition, identification, physical use, and safety/usability, indicating specific design aspects for development and improving the efficiency of product development. The UD-Checker is used on a wide variety of Mitsubishi Electric products from home appliances and public equipment to industrial equipment.

The Universal Design Guidelines are a set of standards that apply to a wide range of product development, and were formulated based on the expertise gained through using the UD-Checker. To promote greater usability of our products by all users, including children, senior citizens, and people with physical disabilities, we created guidelines on changes that occur to human characteristics with age and that consider disabilities. The guidelines are structured in the same way as the UD-Checker, which incorporates the four perspectives of recognition, identification, physical use, and safety/usability.
Under a campaign to provide first-rate instruction manuals, Mitsubishi Electric Group is directing its efforts to creating easy-to-read and easy-to-understand instruction manuals to ensure the safe and comfortable use of our products. Forming the basis of this effort is Mitsubishi Electric's original "Guidelines for the creation of instruction manuals for home appliances—Instructions." To raise the quality level of instruction manuals, this handbook is distributed to all affiliates in Japan who handle home appliances.
Our Quick Guide (Basic Operations) enlarges each button, allowing users to recognize at a glance which button they should push on their remote control. In addition to this, large font sizes and ample margins make the explanations extremely easy to understand.

In fiscal 2019, following the International Association for Universal Design (IAUD)’s evaluations of Mitsubishi Electric’s developments based on experiments targeting various users, we won a total of eight awards at the IAUD International Design Awards. The accolades included the Gold Award for the "small refrigerator for hospital patient use," "full-color LED displays in railcars," and "Car navigation series: Gathers InterNavi Premium," as well as the Silver Award for the "Cordless Stick Vacuum Cleaner JXH iNSTICK ZUBAQ."
Mitsubishi Electric aims in fiscal 2020 to continue creating universal design products that take ingenious approaches and consider various perspectives across a broad range of fields.
