Imagine a 20-30% drop in your manufacturing costs

Compliant mechanism can achieve a big reduction in your manufacturing and production costs.

It is also the most ergonomic form or process engineering pathway AI can mathematically design.

Advantages
of Compliant Mechanisms


Compliant Mechanism Design provides significant advantages which can have a significant positive effects on both product costs and performance.

So what exactly is compliant mechanism?

Compliant mechanisms use elastic body deformation to transfer an input force or displacement to another point.​ These are monolithic (single piece) or joint-less mechanisms performing complex actions. They are often a part of complex structures. The elastic properties with no joints provide the means to miniaturize the mechanism. The resulting mechanisms can be made to do precise and repeatable actions.

So why doesn't everyone else do it?

COMBINATION OF
COMPLEX SYSTEMS

 

The main barriers to analyzing and designing compliant mechanisms are:

1. Lack of expertise in Compliant Design

2. Lack of knowledge in mechanism analysis methods and the deflection of flexible links.


3. Fear of changing the status quo from traditional mechanical engineering design.

LIMITATION OF LIMITED MOTION IN COMPLIANT SYSTEMS

The motion from the deflection of compliant links is limited by the strength of the deflecting component. Unlike a pin joint, a compliant link is unable to reproduce a continuous rotational motion. We take this into account in our design process.

NON-LINEAR EQUATIONS, HENCE DIFFICULT TO
MANAGE

Since flexible links undergo large deflections, linearized beam equations are no longer valid. Nonlinear equations must be used that account for the geometric nonlinearity caused by large deflections. Compliant mechanism analysis and design are tougher than that of rigid-body mechanisms.

FATIGUE LIFE UNDERSTANDING / DESIGN NECESSARY

Compliant members are loaded cyclically when a compliant mechanism is used. And hence, it is essential to design those members such that they will have sufficient fatigue life to perform their prescribed functions.

Technology

Manufacturing Techniques for Compliant Mechanisms


Based on the methods used and the type of mechanisms created using them, there are four broad categories of compliant mechanisms available today.

3D Printing


Also, called Additive Manufacturing (AM). It is used to create a 3D object in which layers of material are formed under computer control to create an object.




Injection Moulding


It is a process of manufacturing parts by injecting material into a mold.




Lamina Emergent Mechanism


LEM is initially a flat sheet. It unfolds to simulate movement by the interaction at the seams, which are living hinges fabricated into the material.




Electrical Discharge Machining


Also, called Subtractive Manufacturing Here the desired shape is obtained by removing material using electrical current discharges. Electrodes are separated by a dielectric liquid and subject to an electric voltage.

Case Studies

Actuators
 

An Actuator is a component of a machine that is responsible for moving and controlling a mechanism or system, for example by opening a valve. In simple terms, it is a "mover".

Market size was 49.2 B$ in 2016, is projected to be 78.9B$ by 2025.

About

We are a team of experts in various fields of engineering with the sole aim of changing the status quo mindset in mechanical engineering design which still uses age old design methods. We begin with the process of ‘Compliant Design’ assessment. 

Compliant Mechanism Design helps you achieve this with: 

  • Reduce Part Count — reducing parts and hence of manufacturing costs - as high as 30% in some cases

  • Niche Applications — Designing parts for niche applications like Space and Medical fields that not possible with conventional methods

At CMDE Labs, we provide strategy and material on the latest production techniques like photo-lithography, LEM, and 3D printing. In addition, we also guide you on generating intellectual property.
