In modern camping and wilderness cross-country, traditional solar panels are huge and heavy, occupying a lot of trunk space. Moreover, due to its rigid shape, it is extremely picky about the terrain when building, and is often paralyzed when facing rocky shrubs or narrow cars. We were looking for lightness in the outdoors, but were forced to bring along the most cumbersome and accommodating physical encumbrances. To this end, SUNROLL from the "ancient scroll and flexible technology symbiosis" cut, subvert the traditional interactive form of photovoltaic charging. We introduce the cutting-edge flexible thin-film solar technology, so that it can be quietly rolled into a compact body at ordinary times, and can be extended gracefully on any terrain with a pull, allowing technology to blend into nature. In the face of outdoor pain points, the design gives an extreme functional closed loop: through the integrated structure of the reel, the storage volume and weight plummet by 70%, but when fully stretched, it can instantly release the large lighting area. The yellow multi-dimensional interactive handle at the front end of the reel integrates the three forms of standing, suction and hanging, which can change into a tripod, magnetically attract off-road body or hang on branches in seconds, and eat any tricky wilderness scene. Leave the bulkiness to the past, and return the lightness to the wilderness. SUNROLL uses minimalist architectural geometry to wrap flexible technology, no longer allows users to accommodate the environment, and reconstructs the symbiotic relationship between people, equipment and nature.
