Outline of Final Research Achievements

In order to ensure the proper fit of the lullaby belt, we measured the belt looseness of the wearer, measured the buttock pressure of the child inside the belt, and evaluated the posture of the child, and created a prototype that can sense the belt looseness of the wearer and the child's environment.
In addition, an Internet survey was conducted to understand user needs, and those with experience using a lullaby belt were asked to select a product with a good balance of the following 8 criteria: "ease of use," "safety," "diversity of purposes," "price," "design and material," "ease of maintenance," "impact on the baby," and "burden on the mother. Those with no experience in using the product were found to place particular importance on "safety. These results clearly indicate that users desire a lullaby belt design that can be properly fitted.

Academic Significance and Societal Importance of the Research Achievements

子守帯市場規模は年々増加している。その一方で、落下事故やヒヤリハットの報告があり、その要因は不適切な装着が大きい割合を占める。不適切装着となる原因は、子守帯の装着しにくさ、機能の複雑化にある。
今回の成果は、不適切装着になりにくく、さらにユーザーニーズに合った子守帯設計である。これにより、育児中の母親が安全に使用することができるという最大の役割を果たすことに貢献している。さらに、今回の知見は子守帯だけではなく、あらゆる製品にも応用が可能となり、ユーザーは今以上に機能性も重視した使いやすい製品を手にすることが可能となる。
