Material Innovation: Explore new materials or combinations of materials to enhance luggage durability, weight, and aesthetics. This could involve using lightweight yet durable materials like carbon fiber composites, innovative fabric blends, or eco-friendly and sustainable materials.
Smart Luggage Features: Integrate smart technologies into luggage designs, such as built-in GPS tracking systems, electronic locks, USB charging ports, integrated scales, or even biometric recognition for added security and convenience.
Modular Design: Create luggage with modular components that allow customization and flexibility. This could involve detachable compartments, expandable sections, or interchangeable parts that cater to different travel needs and preferences.
User-Focused Design: Conduct extensive user research to identify pain points and design luggage solutions that cater to specific travel needs, such as specialized compartments for electronics, improved organization systems, or easy access pockets for travel essentials.
The most cost-effective way is to innovate in color, different colors give people a very different feeling, bright colors can always make people notice at the first glance, the combination of different colors has become a popular trend.

Just like the luggage we made above, although the style has been very common, but the collocation of different colors gives people a fresh feeling
