A pattern to encircle, envelop and crush..
A Metaphor to Solve a Problem
Encircle it.
Look at it from different directions.
View from different perspectives.
Upside down - Back to front.
Zoom in - Zoom out.
Watch a Solution Grow!

Orthosis - added to the bodyStart with the fundamentals - What is the problem?

New HorizonsTechnologies that behave like muscle, control methodologies that exploit principles of biological movement - device structures like the skeleton

Some process steps
✤ Identify the limitations of current functionality
✤ Formulate the gaps as biological questions - How in the World?
✤ Search for nature’s solution - Taxonomy
✤ Generate some product ideas
✤ unique?
✤ cost-effective?
✤ sustainable?

Orthoses are addedand yet .. involve a cost
•Control Motion at a Joint or Joints - Allowing, Resisting, Blocking
•Control Positions of Body Segments -Correcting and Aligning
•Redirect Forces from Body Tissue - Relieving, Sharing Load
Cost - Cosmesis, Comfort, Encumbrance, Weight, Ease of Use

Now you have your great concept!
But you still have a long way to go..

Those who go first just might get opposition from the natives

Lead with Business Strategy - Support with Design
As businesses adapt to meet new market needs and opportunities, strategy must lead, design must
contribute.
Designers must think like business people and create like artists
