Jawaharal - Design Inspired by Limpets - Open 2011 Jawaharal - Design Inspired by Limpets - Open 2011 Presentation Transcript

  • Limpets – A Biomimicry Approach
    Lavanya Jawaharlal
    Diamond Bar High School
  • Junior at Diamond Bar High School, CA
    Visited Costa Rica in April 2010
    stayed in the rainforest for 1 week, near Osa Peninsula
    Considered to be one of the most bio-diverse places in the world
    Inspired to learn more about nature  Biomimicry
    Background
  • bio - meaning life
    mimesis – meaning to imitate
    An attempt to emulate nature’s form, process, and ecosystem
    nature has already solved many of the problems humans face today
    Biomimicry
    http://www.biomimicryinstitute.org/about-us/biomimic.html
  • Nature has had more time to evolve and change accordingly
    Humans have had very little time
    Nature as a guide
    Measure, the rightness of the function
    Mentor and Measure
  • Adam Nieman
  • Nature Inspired Designs
    Examples
  • Burr
    Photo Burr: http://www.mnn.com/health/fitness-well-being/photos/7-ultra-green-extreme-sports
    Engineering Design: Velcro
    Plant: has small hooks on the end of the burr needles
    Mimic: hooks to create velcro
    Effectiveness: easy attachment for materials
  • Engineering Design: Zimbabwe building
    Natural Mound: has a self-cooling system
    Mimic: the building uses large chimneys like the tunnels in the termite mound
    Effectiveness: uses 90% less energy to heat/cool the building
    Termite Mound

  • Member of the MolluscaGastropoda family
    Are found mainly in the mid-intertidal and sub-tidal zones
    Clings to rocks and uneven surfaces
    Have an oval-shaped shell
    Limpets
    Lavanya Jawaharlal, Costa Rica 2010
  • Three parts to a limpet
    Head-foot: contains the locomotion and sensory reception
    Mass: contains organs
    Mantle: the outer shell protecting the mass
    Body Composition

  • Limpets have not been part of an engineering design
    How can limpets help us?
    The strength could be imitated to make fasteners that are optimal and non-toxic
    *Today, there are adhesives, such as epoxy and super glue, that produce excess waste and toxic
    *fasteners, like suction cups, can not maintain a grip on uneven or unsmooth surfaces
  • holding force
    Multi-terrain clamp
    cap/plug
    Applications
  • Measuring the Force
    experiment
  • touch a limpet, the mass and mantle stiffen
    as tapping increases, the holding force increases (Smith 1991)
    Response Test
  • To test the holding force:
    Tied a thread around the shell
    Used a spring scale to measure up to 50lbs
    Smith (1991) designed a similar experiment
  • Measure force of the waves
    Lift and drag
    Find the hydrodynamic forces
    Simultaneously measure the holding force of limpet
    Holding force:
    Use a sensor-based system connected to a computer
    Load cells
    Strain gauges
    The Ideal Experiment
  • Unable to complete an ideal experiment
    Experiment can not take place without jeopardizing the limpet’s natural behavior
    Intertidal zones leave room for a large error of measurement
  • Thank you teacher (Nature) for the inspiration
