Project

Smart Paw

The purpose of the project was to carry out the development of a physical product from initial idea to a fully functioning concept, an Alfa product. The project aimed to give hands-on experience of the complete product development process, including design, surface modeling, construction, and prototyping, while ensuring manufacturability and technical feasibility.

The project required the design and development of a new computer mouse for a defined target group. The group selected children aged 9–13 as the target users, focusing on size, ergonomics, form, and color to meet their specific needs. Key constraints included designing a product suitable for mass production through plastic injection molding, ensuring appropriate draft angles, and integrating an existing circuit board from a reference mouse. The design process included sketching, physical modeling, 3D surface modeling in Alias, detailed construction in Catia V5, and 3D printing of a full-scale prototype with integrated electronics.

The project resulted in Smart Paw, an ergonomic mouse designed for elemantary school students. As digital tools increasingly shape the learning environment, children spend more time using computers at school. Smart Paw addresses the need for an ergonomic, age-adapted device while also aiming to spark interest in technology, a core subjet in the school curriculu,. The final outcome is a fully functioning prototype that demonstrates both technical viability and user-centered design, combining ergonomics, manufacturability, and inspiration into a cohesive product concept.

Design Process

01 Benchmarking

After the target group was set, benchmarking was conducted to explore various computer mouses on the market. During the benchmarking ergonomic products were explored.

02 Ideation

Idea generation focused on creating fun and engaging solutions aimed at increasing ergonomics and the target group’s interest in the subject of technology.

03 Clay Model

The computer mouse was built in clay to evaluate shapes and forms to get an ergonomic computer mouse. The target group tried the shape and assessed the ergonomics of the computer mouse. 

04 Surface and Solid Modeling

The clay model was scanned and used as a base to create a digital surface model in Alias Autodesk. The surface was exported to Catia V5 to create a solid model. 

05 Prototyping

The solid model of the computer mouse was 3D printed. A circuit board was implemented in the 3D-printed model and was evaluated by the target group.

Result

The project resulted in the Smart Paw, which is a beta product. The Smart Paw has flexible and soft shapes to offer a natural position for the hand to improve ergonomics. The size of the mouse is based on anthropometric measurements to fit middle school students ages 9-13 y/o. The inspiring computer mouse is offered in different colors to suit students’ preferences. The transparent part was implemented in the hope of attracting and interesting more students to engage in the subject of technology and to increase their understanding of the technology behind the computer mouse.
