Implementation Achievements in Research and Development (R&D) and Manufacturing (Monozukuri) Results

Case Study 1: Major Automobile Manufacturer's Research Laboratory

There was a need to receive sensing data from a high-speed rotator. We requested Marutsu to develop a circuit board with a mechanism to supply power to a high-speed rotator via a wireless power supply and which could receive sensing data via a wireless power supply antenna.

【Details of the Request】
Based on our request, Marutsu carried out prototyping using a basic design, circuit design, MCU programming, circuit board design and manufacturing. Next a test device was produced for a high-speed rotator in a high-temperature environment. Environment tests were carried out, and the finished product was produced, satisfying all the required specifications. At the end, we also ordered case processing and harness processing, and testing of the actual machine is underway. In this case, everything was ordered through the "Proto Factory". Various issues were resolved and the desired results were achieved.

Case Study 2: Major Planning Company

【Background】 A functional liquid crystal film, which can switch between transparent and opaque, is powered by a rechargeable battery and driven by an AC signal. In addition, the final objective is control from a smartphone via BLE communication.

【Details of the Request】
 As a planning company, we had some ideas, but didn't have the means to achieve them, and requested help from Marutsu. They flexibly responded to changes in the specifications. Since production was left up to Marutsu, we could focus on marketing and the user interface. We requested only the processes that we needed, which was very helpful. We designed the housing ourselves and requested help in developing the circuit board, prototyping, and mass production. We received a progress report for each process, and the explanation was easy to understand even for a layman. Prototyping was carried out based on a basic design, circuit design, MCU programming, circuit board design, and manufacturing. At the end, we requested Marutsu for a mass production model with fewer parts with a view of cost reduction. We were able to insert the basic functions into the expected size. In addition, the interface now supports Type-C connections.
