An explorative study of design packaging of metal cans for elderly nutrition

Master Assignment

Sep 2023-May 2024

Assignment

  • How should can packaging be designed for elderly people such that it is easy to open, hygienically re-sealable, easy to handle and shows evidence of tampering? Easy-opening
  • To study the impact of face on packaging. visual-graphics

Research Phase

Use and user study 1

    To find how elderly interact with POE-Rivet cans
combo

After interaction they were asked 6 questions with respect to opening of the can

overall-steps of can opening
results-of-use-and-user-study-1

7 participants found difficult or very difficult to understand the opening.
9 participants found difficult to provide the initial force to open the can.

Force testing

    To measure how much force elderly people where able to afford.

Use and user study 2

    what was the experience after opening the can with different openings?
73mm-cans keywords used by participants to explain POE-Ringpull results-of-remaining-73mm-cans

  • POE-Ring pull works better than POE-rivet type for elderly people.
  • Visual (Geometrical , material, other) cues along iterative and intuitive thinking is the reason behind successful understanding and opening of POE-Ring pull.

Design phase

Design Challenge

“Develop innovative design ideas that push the boundaries of metal packaging while also balancing the innovation scale for elders.”

Testing of existing resealable options on metal cans

    To find which is the easiest resealable options(metal based) for elderly.

Usability Testing

  • To understand how elders interact with the concept cans
  • To score the concepts based on different affordances.

Graphics and Hypothesis creation

  • Two different hypothesis was formed

    • H1:"Elderly participants will focus more on informational content than emotional content.”

    H2: “Elderly women may prefer graphics featuring older woman over graphics featuring cultural connect”

  • Different Areas of Interests( AOI)

H1:Elderly participants will focus more on nutritional information or health benefits displayed on the cans rather than the graphics

The first hypothesis H1 is false.

H2: Elderly women may prefer graphics featuring older woman over graphics featuring cultural connect.

Conclusion

Easy opening

  • POE-Ring pull is best option among the different easy openings.It is more understandable, intuitive , easy to manipulate.
POE-Ringpull

Easy Resealing

  • Concept 6 was chosen . It was refined and production techniques were derived.
Concept-6

Graphics

  • Participants were emotionally oriented than informationally focused.
  • Cultural based artworks are liked by elderly women more than others.
