CACO: Calm and Carry On – Redefining Transit Design for Urban Architecture

Urban life often places immense demands on individuals who rely on public transportation as part of their daily routine. Congested spaces, constant physical contact with transit poles, and the pressure of carrying personal belongings all contribute to a stressful commuting experience. Addressing these issues through innovative design, CACO (Calm and Carry On) offers a compact, multi-functional personal device that merges hygiene, comfort, and utility. Designed by Farwa Mumtaz and Patriceia Yu, this Honorable Mention entry of the @ease competition highlights how industrial design in architecture can transform urban commuting.

Transit Design and Human-Centered Architecture

One of the most pressing needs in contemporary urban infrastructure is public transportation design that considers both hygiene and user comfort. With millions of people relying on shared transport systems every day, CACO recognizes the importance of creating a safe, stress-free interaction between commuters and transit architecture. By introducing a soft silicone shield that can snap onto transit poles, it prevents direct skin contact with germ-prone surfaces, enhancing both physical hygiene and psychological ease.

Multi-Functional Design Features

CACO’s design extends beyond hygiene—it’s a versatile tool tailored for urban living:

• Snap-On Mechanism: Quickly attaches to transit poles, ensuring stability during crowded rides.
• Soft Stress-Relieving Grip: The pliable silicone surface provides a tactile sense of relief, acting as both a functional handle and a stress management tool.
• Bag Hooks: Built-in hooks allow users to hang personal belongings, freeing hands during transit.
• Portable Use: Lightweight and foldable, CACO can be carried in bags or attached externally for easy access.

This blend of functionality elevates CACO beyond a hygiene device—it becomes part of human-centered architectural design, directly responding to the evolving needs of urban commuters.

Material Innovation for Everyday Architecture

The product’s materiality contributes significantly to its functionality. Its pliable cushion ensures comfort, while a robust shell maintains durability under daily wear and tear. The elastic mold adapts seamlessly to various pole diameters, while the textured grip surface enhances usability. Together, these material properties demonstrate how design innovation in public transport architecture can reshape urban commuting experiences.

Reducing Stress in Transit Architecture

Modern public transportation isn’t just about efficiency—it’s about mental well-being. CACO incorporates the concept of mindful commuting. Its soft surface encourages stress relief through a simple squeeze, while its portability ensures that relief is never out of reach. By embedding comfort into daily interactions, CACO transforms routine travel into a calmer, more manageable experience.

A Step Towards Sustainable Urban Design

In the broader context of sustainable urban architecture, CACO contributes to long-term resilience. By reducing the spread of germs and alleviating commuter stress, it indirectly improves public health and productivity. Moreover, its compact, reusable form reduces reliance on disposable protective products, aligning with environmentally responsible design practices.

CACO exemplifies how innovative transit design within architecture can bridge the gap between function, comfort, and health in crowded cities. By integrating hygiene protection, stress relief, and practical storage into one device, it redefines the way we interact with everyday urban infrastructure. The project by Farwa Mumtaz and Patriceia Yu is a testament to how thoughtful design can empower commuters and enrich the architectural fabric of public transit.
