I’m developing a new line of backpacks aimed squarely at elementary school children and need a practical yet engaging design that can go straight from concept to the factory floor. The bag’s core job is simple—carry everything a young student needs each day—yet the details matter. I want to see: • Extra compartments that keep notebooks, art supplies, a lunch box, and small electronics neatly organized. • An ergonomic form scaled to smaller bodies, with padded, adjustable shoulder straps and a ventilated back panel so the load feels light even on a long walk. • Reflective materials integrated into the front, sides, and straps so the child stays visible during early-morning drop-offs or late-afternoon pickups. Please show how you’ll balance durability, weight, and cost through your choice of fabrics, zippers, and stitching. Bright, age-appropriate colorways or patterns are a plus, but the focus should always be comfort and safety. Deliverables I need from you: 1. Concept sketches and color options. 2. Detailed 3D mock-ups or CAD files illustrating dimensions and materials. 3. A tech pack ready for sampling, including fabric specs, hardware lists, and construction notes. I’ll review initial concepts within 48 hours of submission and provide targeted feedback so we can iterate quickly. Once the tech pack meets the criteria above, the project is complete and ready for hand-off to my manufacturer.
