The primary solution: the outer balcony. Technical contradiction: 6. The area of a static object is VS 13 stability. Recommended invention principle 2.38. Extraction principle and strong oxidation principle. Based on the principle of extraction, the external connecting plate is movably installed in the middle layer of the balcony, with clothes hanging on the upper layer and shoes hanging on the lower layer. The original external board leads clothes to drop onto the balcony. Apply the principle of strong oxidation, and use wind energy, heat energy or ultraviolet energy to dry shoes.
There are many technical contradictions here. Try it yourself, and you will find a better solution.
