Project Storyboard!

Here is an interactive storyboard of our design process!

The MEng project is a year-long project required by the MEng program at Cornell. With a group of 8 other students, we were tasked to redesign the student experience so that they don’t just get by but thrive.

Group members: Nirmal Antonyselvaraji Jhon Leonard Ar, Lingxiang Cai, Grace Chen, Italivi Diaz, Yu Guan, Jinfeng He, Qisheng Su, Haolin Wu, Wenhao Zhang
Advisors: Sirietta Simoncini, Robert Shepherd

Project Timeline:

Project work done in conjunction with and on top of Innovative Product Design (MAE 5340)

Empathize & Unpacking Phase:
6 September 2024 - 18 September 2024
  • Empathy field work (EFW)
  • Unpacking EFW
empathy field work map
Modeling Phase:
18 September 2024 - 25 September 2024
  • Create emotional donut
  • “How might we” diagram
  • Flow of thoughts
  • Creating personas – persona descriptions & personas flushed out
  • Persona context diagram
  • Criteria comparison matrix
Ideate Phase:
25 September 2024 - 2 October 2024
  • Brainstorming sessions
  • Desirability vs. feasibility graphs
  • Choose 3 final concepts
  • Product concept sketches
  • Persona concept sketches
  • Branding/logo creation

Our top 3 ideas after brainstorming:

1st Review
2 October 2024 - 7 October 2024

After 1st review with industry advisors:

7 October 2024 - 28 October 2024
  • Chose what project idea to work on (we chose the acupressure inspired massage foot rest)
  • Create our first rough prototype with cardboard and tape (Design Zero)
  • User testing
  • Modeling the results from our user testing
  • Conjoint Analysis
  • Iterate our prototype based on feedback from user testing and conjoint analysis (Design One)
Design Zero

Features of our first prototype (Design Zero)

  • Materials: cardboard and tape
  • Rocking chair inspired rocking mechanism
  • Ball and socket joint connected top pad to baseboard (middle picture)
  • Removable acupuncture mat function (picture on the right)
Design One
28 October 2024 - 8 November 2024

Features of our iterated prototype (Design One)

  • Materials: acrylic, foam, ABS, COTS acupressure mat
  • Inclined angle for more comfortable foot resting position
  • 3D printed rocking hinge joint that connects base to board
  • Removable and customizable pad feature
2nd Review
8 November 2024 - 11 November 2024

After 2nd review with industry advisors:

  • Explore manufacturing processes
  • Discuss industrial design – how to make our design more visually appealing
Design Two
11 November 2024 - 5 December 2024

Features of our final fall prototype (Design Two):

  • Materials: MDF, ABS, rubber, foam, glue
  • Chinese acupressure inspired massage pad made from ABS and rubber
  • Inclined angle for better comfortability
  • Foam underneath acupressure inspired massage board allows for many degrees of motion for the foot (instead of just front and back like in Design One)

Spring 2025:

Throughout the spring semester we continued to design, iterate, and test, specifically improving and adding the following:

  • Improving acupressure pad:
    • Changing the material to a dual material: silicon and 3D printed PLA inserts
    • Changing the acupressure zones to a foot like shape
  • Adding electric modules:
    • Vibration module
    • Heating module
    • Fan module
    • Button module to control the other modules
  • Changed the inclined angle to 20 degrees
  • Materials: 3D printed PLA, memory foam, electronics, silicon
