THE AIM OF THE PROJECT

  • Redesign and develop
  • Focus on customer-based research

GSK Avamys

Evolution

VoC Research

  • Venn diagram
  • Identify desirable features of nasal spray from HCP and consumer point of view.
  • Overlapping section shows features with greatest significance.
  • Indicates which design features to focus on the most.

VoC Research

  • Specific consumer research conducted for the Avamys device.
  • Overall consumers were highly satisfied with the device.
  • Although some areas where consumers were not satisfied and areas which could be improved.
  • Examples:
  • Mechanism to administer the medicine requires too greater force.
  • Smaller and lighter

VoC Research

  • Various factors that a HCP would take into account when prescribing a treatment.
  • Factors of greatest importance closer to the top.
  • Factors of less importance closer to the bottom.
  • Significant:
  • Familiarity and safety at the top
  • Easy of use above cost

Existing Product Research

Pro's

large nozzle, market leader, aesthetic, easy to use

Small, Intuitive, Aesthetically pleasing, Indicator of remaining medicine.

Con's

Can't see the remaining volume of medicine

Small bottle, No lid, Difficult for elderly users.

Pro's

Analysis against Design Specification

Ergonomic, simple to use and suitable for all ages.

Small and simple. Can easily see remaining medicine.

Con's

Large and expensive to manufacture

Lack of gripping surface and difficult for the elderly to use

Initial Concepts

So, what do you think?

CAD

Design 7

Initial Concepts

Pros

  • Easy to use
  • Small
  • Interchangeable bottle

We used these designs for rapid prototyping.

Cons

  • Complexity of design
  • Easily breakable

Design 1

Rapid prototyping

Design 3

Design 7

  • Developed designs using a rapid prototyping method - 3D printing.
  • Important for ergonomics.
  • Visual aid for gaining consumer feedback.

Design 6

Design 2

Consumer Feedback

  • Created a questionnaire
  • Gain feedback from consumers
  • Highlight areas for improvement
  • Revealed favourable aspects:
  • Reusability - Design 7
  • Visibility of medicine - Design 7
  • Ergonomics - Design 3&4
  • Intuitive operation - Design 3&4

Pros

  • Easy to use
  • Stylish
  • Interchangeable bottle

Cons

  • Some may find difficult to grip
  • Seizing of button

Further Development

Design 3

In Summary...

  • Basic frame incorporated from designs 3&4.
  • Intuitive operation and ergonomic design achieved.
  • Wrap around window developed into side entry.
  • Combining reusability and visibility of medicine aspects from design 7.

Design 5

Pros

  • Easy to use
  • Suitable for people with impairments
  • Interchangeable bottle

We would appreciate any constructive feedback or questions you have.

THANKS FOR LISTENING

- Our design is a slimmed down, light weight evolution of the original.

- Can purchase a single unit and then dispose of cartridges when medicine runs out.

- Intuitive cartridge system for ease of use and visibility of remaining medicine.

- Adapted internal mechanism and improved ergonomics for more comfortable use.

Final Design

Cons

  • Bulky
  • Complex shape
  • Not as portable as other products on market

Design 4

Aesthetic Variations

= More user choice

And here's how it works...
