Unverified容量与重量、结构挺括度相互矛盾：大容量包为了防塌陷会用更多支撑板和厚面料从而更重，追求轻量化的包则往往软塌、装满后变形显乱91% similarUnverified承重与折叠便利性存在矛盾：承重越高需要越厚的硬质支撑板和金属框架，折叠后越难压缩、越重；纯软布折叠款收纳最省空间但基本不能承重89% similarUnverified折叠便携性是核心卖点，但折叠款普遍牺牲结构硬度，侧壁较软、重物堆叠时容易变形倾倒，承重能力弱于硬壳款。87% similarUnverified折叠便携性与承重结构互相矛盾：能压扁收纳的软体款承重普遍不足，承重强的硬壳款几乎不可折叠且平时空占空间87% similarUnverified材质越硬承重越好但越重、韧性差易碎；软质折叠箱轻便省空间但不可堆叠承重，二者不可兼得，重物运输选硬质，临时/换季收纳选折叠款86% similar
