増量

1. Origins, structure, and basic meaning

• Structure: Written 増量 and read ぞうりょう, it means increasing the quantity or weight of material or product content.
• Basic usage: It applies to using more fabric in a prototype and a package made heavier by added content.

2. Common pitfalls and similar expressions

• Quantity rather than packaging size
  • The relevant amount grows; a larger-looking container alone does not establish an increase.
