Are you looking for revolution rather than evolution, breaking the mold, thinking your way outside of The Box? We keep up with the best of what’s happening in technology and apply a disciplined creative ideation process to challenges and problems all the time. We will work closely with you in developing your product idea and create an innovative, elegant, well thought-out, manufacturable and fully-CAD-documented design. Contact us at design@contechs.com to see how we can help you journey the world outside the Box.

performance optimized

For aerospace, energy, sporting goods and other high-technology products whose viability depends on extreme light weight, efficiency or other high-performance factors, we can apply our systematic approach to create performance beyond what may have been thought possible.

Our comprehensive System-Level Analytic Modeling and Optimization method (SLAMO), developed over the last several years, enables us to evaluate performance tradeoffs and perform global numerical optimization. In this method, system goals are identified and reduced to one or more FOM (figures of merit) and constraints.  The various temperatures, pressures, ratios, dimensions, etc. are parameterized. Mathematical relations, simple at first but evolving in sophistication and accuracy, are developed to inter-link the parameters while a top-level optimization routine continually adjusts individual parameters looking for system improvement. CAD models are linked to dimensional parameters to allow nearly immediate visualization and/or FEA confirmation of the evolving design.

This methodology has been applied in the past to the system tradeoffs involved in optimization of an experimental resonant radioisotope powered heat engine/generator intended for the Pluto Express deep-space probe.  This approach allowed a system that required only one Plutonium General Purpose Heat Source rather than two for a competing dynamic system or five for Thermal PV cells.  The system mass was reduced by a factor of two through this optimization process.  A similar approach was used in the modeling of a waste-heat driven Stirling engine for generating onboard electrical power for Aircraft.  A number of cryocooler projects also benefited this analysis including a 65K single stage, a two-stage 30K and a multi-stage 11K cooler.

With this approach, it is much easier to determine sensitivity to the various assumptions made, likely deviations in the as-built equipment, and off-design operating conditions.

engineering research & analysis

Concepts, prototypes, test facilities, testing, and designs; all are supported throughout with sound engineering calculations quantifying such factors as strength, heat transfer, fluid flow, durability and other relevant parameters that are important to the success of the idea. Creative concept development is coupled with in-depth quantitative evaluation to generate innovative, cost-effective solutions. We utilize state-of-the-art science, methods, materials and engineering techniques, information technology, computer-aided design; e-mail us at analysis@contechs.com to see how we can help you.

available product designs & concepts

Over a decade in research, design and development has enabled us to collect and originate hundreds of product concepts and designs, many of which are available for licensing or cooperative development. Please e-mail productdesigns@contechs.com for a product summary list in your area of interest.

market optimized

More often, products must balance their performance against the real-world factors of manufacturing cost and the market: what users value in a product and how much each factor or feature is worth to them. This version of our optimization process uses analysis of existing products and market research to fold in specific, quantitative data about what users want and how much they want it. In addition, a routine that estimates relative manufacturing costs for product variations aids the maximization of Return On Investment in a new product.
