Embedded Linear-Motion Developable Mechanisms on Cylindrical Surfaces
This work explores mapping straight-line and linear-motion mechanisms onto cylinders.
PAPER TITLE
Embedded Linear-Motion Developable Mechanisms on Cylindrical Surfaces
ABSTRACT
This work introduces methods for developing embedded straight-line and linear-motion mechanisms on right circular cylinders. Developable surfaces, particularly right circular cylinders, are the manufactured embodiment of many products. Functional linkages are traditionally not geometrically constrained to a body and often dictate the final shape of the housing they reside. This work explores mapping straight-line and linear-motion mechanisms onto cylinders for practical design. Potential applications for when an embedded cylindrical developable mechanism capable of deployment and generation of linear motion would be useful are discussed. An in vivo wiper mechanism to clean obstructed laparoscope lenses during surgery is investigated to physically demonstrate the concepts introduced in the paper and to illustrate an example application.

The Ortho-Planar Spring is a compact spring with a platform that undergoes a large displacement in either direction, but does not rotate like conventional planar springs. This invention has numerous advantages. Compact: this planar spring is much more compact than traditional helical springs. No rotation: unlike conventional-planar springs, the center of this spring does not rotate relative to ...

    Currently there is an issue in joysticks for gaming controllers where the mechanism’s friction releases particles that jams the sensors (drift) and the lost material makes the joystick loose over time (needing a dead zone configuration). If this mechanism was small enough, instead of motors there were sensors and instead of the truster there would be the thumb pad the sensors might not be jammed by particles, the joystick might not get loose over time and it might reduce the number of parts drastically as there wouldn’t be a need for a spring to return the joystick to center and about six other parts. ua-cam.com/video/vQesgAtr2e4/v-deo.html

    Hey, thats very nice. I wanted to know is it the variation of thickness along the extrusion curvature that can yield for any material's compliant mechanism tendency. And if so, how do you determine the optimal thickness and it's location ? is the location through the springs in your PRBMs(pseudo rigid body models)? Do you also think polar moment of inertia can help predict curvatures thickness ? Can you also tell me which filament you used to obtain this specific design ?

    You can get kind of the same effect from a 3 x 5 card. Bring the two ends together, with one hand and then hold the rounded middle between your middle finger and thumb and then use your index finger to push and the middle a little bit. Then you can open and close by just squeezing with your middle finger and thumb. A very similar geometry. Thank you for submitting your 3D Compliant Mechanisms to Thingiverse.
