PocketPal

Small essentials are easy to lose

We started by asking what daily challenges people face organizing their essentials. Interviews with college freshmen pointed to one pain point: carrying keys, cards and cash without misplacing them.

• Combine a wallet, key holder and phone attachment in one product
• Address limited pocket storage, including in women's clothing
• Balance function and style

From interviews to a tested prototype

We moved from sketches to prototypes, gathering feedback at each stage and trying different materials, attachment methods and storage layouts.

• User interviews to understand needs and preferences
• CAD models and simulations to optimize dimensions and function
• Prototyped a hinge mechanism for quick access to stored items
• Tested adhesive strength and durability under various conditions

Pocket-sized, under 50 grams

• Capacity: up to 3 cards, 1 key and 5 bills
• Material: ABS plastic, for durability and low weight
• Attachment: 3M adhesive, secure but easy to remove
• Size: 5 × 10 × 0.5 cm
• Weight: under 50 g
• Customization: multiple colors and designs

Positive prototype feedback

Early prototype users praised its functionality and compact design. The target audience runs from college students to busy professionals.

With a low manufacturing cost and high perceived value, PocketPal fills a gap for multi-functional phone accessories.
