Industrial design encompasses not only the exterior aesthetics but also the internal components. With careful consideration of various constraints, our team has effectively streamlined the interior of the product, removing unnecessary visual elements. We have distilled it down to the essential features that are crucial for installers, such as incorporating horizontal indications, concealing reset mechanisms, strategically locating pogo pins, and highlighting the critical cable gland nut in blue to ensure proper water seal installation. By focusing on these details, we have optimized the functionality and usability of the product, delivering a seamless experience for the installers.
