RFP Title
Moving Force Across a Defined Space with Precision and Reliability
RFP Description

NineSigma, representing a Global Manufacturing Client, invites proposals for cross-industrial technologies capable of delivering a controlled force to move a payload in a variety of machine operations.

Background

Linear actuators drive a wide range of essential functions in the industrial and manufacturing fields. Discrete forces delivered along a defined linear axis can be applied to many areas within a single piece of machinery. Variations in the force, stroke, precision, and duty cycle of the actuated system are optimized to drive a single function, and these elements can vary greatly between different pieces of equipment.

 

 

A range of five (5) representative applications are shown below as reference:

 

  A B C D E
Moving mass (kg)   5500   6400   7900  10400 22100
Target Time to Stroke (msec) 640 730 900 950 1100
One-Way Stroke (mm) 645 730 975 975 1085

 

Traditional actuator technologies, such as hydromechanical, electromechanical, and pneumatic, all face limitations in functionality. These include one or more of the following: efficiency, accuracy, repeatability, contamination from the working fluid, high operating and maintenance costs, and high capital costs. Most often, one limitation is eliminated at the expense of another. This is especially true in high force and/or speed applications.

 

The client seeks partners with novel concepts to supplement systems in their existing infrastructure for delivering a payload. Technologies that improve upon the current state of the art, that make use of non-contact solutions, or that have cross-industry applicability are all of significant interest.

 

Anticipated Project Phases or Project Plan

Phase 1 – Proof of concept

  • In this phase, the proposed technology will be examined for compatibility with the client’s application and will include testing.

 

Phase 2 – Commercial development

  • In this phase, the proposed technology will be integrated with the client’s equipment in preparation for sale.

 

Criteria for Moving from Phase 1 to Phase 2

  • To continue from Phase 1 to Phase 2, it must be evident that the proposed technology is capable of meeting the performance requirements and brings value to the client’s customers in an economical way.

 

 

Key Success Criteria

The successful technology will be able to:

  • Move a payload horizontally and stop it repeatably within 0.005 of an inch.
  • Reduce energy consumption by 20% over existing technologies
    • Note that this could mean the use of low friction sliding technologies
  • Be capable of, or adaptable to, a high volume of cycles in excess of 2 years of continuous movement in the 10 to 30 second cycle range with little to no maintenance.
  • Be capable of exerting a holding force at the terminal stroke position.
  • The times and strokes listed above are for a specific configuration, but the actual stroke/time is customer settable.

 

 

Possible Approaches

Possible approaches might include, but are not limited to:

  • Improvements upon linear actuators (electromagnetic, piezoelectric, etc.)
  • Novel pneumatic technologies
  • Breakthrough mechanical solutions
  • Non-contact solutions
  • Cross-industrial solutions from outside the manufacturing industry

 

 

Approaches not of interest

The following approaches are not of interest:

  • Systems based upon hydraulic technologies (due to both functional and environmental concerns)
  • Traditional ball or roller screw technologies
