【说明】 概念描述 / Concept: 中文:设想一个小型装置（例如压力传感器）安装在马桶座圈/底座附近，能自动识别“坐下/离开”并开始计时;超过设定时长后，通过手机App（以及可选的灯光/声音/震动）进行提醒（可做得更明显但不尴尬），并在App中展示时长趋势与建议。 English: Imagine a small device (e.g., a pressure sensor) installed near the toilet seat/base that automatically detects “sit down/stand up” and starts timing. If the duration exceeds a set limit, it sends reminders (noticeable but not awkward) via a mobile app (optionally light/sound/vibration) and shows trends and tips in the app.
