FlexWorks Software

There are over 14 million CAD users and Makers designing things, and no tool to help make things that Flex-to-Function… until now. In a research project funded by the National Science Foundation, this tool will generate a single-part mechanism. It uses a compliant design methodology invented by UofM Mechanical Engineering professor Sridhar Kota, and it’s primarily meant to help reduce parts and assembly cost.

This software tool can't produce everything that we show possible with compliant design, but it's a start!

Compliant Design

Distributed Compliant Design exploits the elasticity of materials, from plastic to steel. This elasticity can be put to work and flex, in a predicable manner and without over-stressing the material. Applied properly, this design approach results in joint-less mechanisms that can last an extremely high number of cycles. “Joint-less” means no hinges, pins, springs, multiple rigid members, no wear, no contaminating lubrication, and less tooling. And with reduced parts, comes reduced backlash in your mechanism. Almost any assembly of moving parts can benefit. The problem has been that there is no design tool to help create these devices that Flex-to-Function… until now. Our FlexWorks design tool will create a single-piece compliant Input/Output type device from user criteria for its function.

About FlexSys

FlexSys Inc. is a specialty engineering firm that develops and licenses intellectual property to reduce complexity and improve performance of client products. In 2000, Dr. Sridhar Kota founded the company to develop and commercialize his patented design of a shape-morphing adaptive control surface for airfoils. As a professor of Mechanical Engineering at the University of Michigan since 1987, Dr. Kota initiated research in compliant mechanisms in the 1990s and pioneered the bio-inspired concept of Distributed Compliance. In 2015, the 15 year development of FlexFoil™ culminated in successful flight testing by Nasa and the Air Force leading to a Joint Venture with Aviation Partners. With a projected 5-12% in reduced fuel burn from its application, it is expected to be on commercial aircraft by 2020. For more on FlexSys and FlexFoil, visit Flxsys.com

Over the years, FlexSys has demonstrated application in industries including automotive, medical, furniture, prosthetics, marine, and recreation to name a few. Almost any product can be considered for a no-assembly design approach using compliant mechanisms. The company has extensive experience with materials, manufacturing techniques, and control systems for fabrication and testing of functional prototypes. It also developed its own proprietary software for the creation and optimization of compliant systems, and uses a suite of commercial CAD/CAE tools for advanced modeling and analysis. Today, FlexSys is an established world leader in shape-adaptive engineering design and creating devices that Flex-to-Function. The engineers at FlexSys stand ready to review your next product for application.

Wiper - from 15 parts to 3

FlexSys designed, prototyped and tested a new wiper design for a major automaker. By using Distributed Compliant Design methods, we reduced part count from 15 to three. The new wiper design is injection molded of 33% glass filled PBT and won a 2016 JEC Innovation Award. It out performs legacy wipers by delivering more evenly distributed pressure to the glass. It can be made in the USA for less than importing. This one is custom designed and includes the arm. But the patented design is currently available for other automakers or aftermarket makers.

Side Mirror Actuator - from 18 parts to 7

By using Distributed Compliant Design methods and some out-of-the-box thinking, this side mirror actuator was reduced to 7 parts for a 40% cost savings over those benchmarked. Some had as many as 29 parts. This patented design has been prototype tooled and is currently available for licensing.

Even the common stapler - from 18 parts to 3

One day, Professor Kota was standing before his mechanical engineering class explaining the concept of Compliant Systems Design. He picked up a stapler nearby and exclaimed; "There are items all around us that can benefit from using compliant design. I'm sure that even this stapler could be reduced to just a couple parts using this unconventional way of thinking and designing." A masters student took him up on it and re-imagined the stapler into a single joint-less shape that could drop out of an injection molding machine, with two insert molded metal pieces. To this day, it is one of the best examples of thinking out-of-the-box and how compliant systems design can drastically reduce part count.
