Iris Mechanism Generator (Variant 5)

This model is part of a series of Iris Mechanisms I began designing during the pandemic, and it now receives an update after several years. The original model uploaded a few years ago is available here: šŸ”— https://grabcad.com/library/iris-generator-model-3-1 Unfortunately, due to GrabCADā€™s community guidelines, it has been flagged as ā€œtainted due to a violation of community guidelinesā€ and is no longer publicly visible unless accessed via direct link. šŸ› ļø About this Variant In this version, the actuation is achieved by rotating the driving plate. This plate interacts with slots (guides) on each leaf, which in turn execute the opening or closing of the iris. The mechanism has been successfully tested with 4 to 7 leaves, though I do not recommend using only 4, as the slot approaches too close to the edge of the plate. Suggested maximum opening angles (r_max) are: 4 leaves ā†’ up to 45Ā° 5ā€“6 leaves ā†’ around 40Ā° to 35Ā° 7 leaves ā†’ up to 30Ā° Please review the model carefully and test parameters cautiously before applying them in a final design. āš™ļø Notes Open the full assembly file, as part dimensions and parameters are linked directly to it via parametric references. Feel free to use or modify this model as you see fit. (And fingers crossed GrabCAD doesnā€™t report it again šŸ˜…)

Iris Mechanism Generator (Variant 6)

This model is part of a series of Iris Mechanisms I began designing during the pandemic, and it now receives an update after several years. The original model uploaded a few years ago is available here: šŸ”— https://grabcad.com/library/iris-generator-model-5-1 Unfortunately, due to GrabCADā€™s community policies, it has been flagged as ā€œtainted due to a violation of community guidelinesā€ and is no longer publicly visible unless accessed directly. šŸ› ļø About this Variant This version features somewhat triangular leaves that slide against each other. The mechanism operates through two plates: A base plate with straight linear guides, which define the opening/closing position of each leaf A driving plate with curved slots, which actuate the iris motion through controlled displacement This model is a schematic representation, so any manufacturing considerationsā€”such as tolerances between pins and slotsā€”are left to the discretion of the designer using this as a starting point. āš™ļø Notes Be sure to open the assembly file, as the parts are dimensionally linked to the assembly (parametric relationships are defined there). Feel free to use or modify this model however you'd like. (Letā€™s hope GrabCAD doesnā€™t flag this one again šŸ˜…)

Iris Mechanism Generator (Variant 4)

This model is part of a series of Iris Mechanisms I began designing during the pandemic, and it now receives an update after several years. The original model uploaded a few years ago can be found here: šŸ”— https://grabcad.com/library/iris-generator-model-3-1 However, due to GrabCAD's community policies, it has been flagged as "tainted due to a violation of community guidelines" and is no longer publicly searchable. šŸ› ļø About this Variant This version is an Iris Generator where the leaves pivot from one of their ends, and must rotate to open or close the mechanism. Iā€™ve tested this configuration with 4 to 7 leaves, using the following recommended maximum opening angles (r_max): 4 leaves ā†’ up to 45Ā° 5ā€“6 leaves ā†’ around 40Ā° to 35Ā° 7 leaves ā†’ up to 30Ā° The leaves must move reciprocally, meaning they should all rotate the same amount in opposite directions to maintain symmetry. This motion is not included in the modelā€”you, as the designer, can implement the drive mechanism using gears, pulleys, linkages, or any transmission system of your choice. āš™ļø Notes Make sure to open the full assembly file, as the parts are dimensionally linked to the main assembly (parametric constraints are defined at the assembly level). This model was designed with parametric intent and can be customized for different leaf counts or outer diameters.
