Expand any service to see the actual engineering work involved — description, benefits, deliverables, and where it applies.
We figure out what the form, layout and user experience should be before doing detailed CAD work; this involves sketching and modelling how it should look and feel.
We produce parametric 3D CAD models of the plastic enclosures and mounting hardware around a design's electronics that take into account the intended manufacturing process.
We develop the schematic and PCB layout, and ensure that connector footprints and board shape are taken into account to ensure a perfect fit within the mechanically designed enclosure.
We write the firmware used to operate your product's electronics in embedded C and C++. This focuses on sensor sampling and interface control.
We review the electronics and mechanical designs to ensure they are optimized to be easily manufactured.
We simulate mechanical loading and thermal dissipation within a design to ensure that failures do not occur.
We build and integrate mechanisms, electronics and software systems to prove our concepts using 3D printing, CNC machining and electronics prototype construction.
Most vendors specialize in one discipline and hand you off for the rest. We keep mechanical, electronics, and firmware under one roof, from Thane, Maharashtra.

Representative examples of the kind of end-to-end product work we take on.
Challenge-A startup had a smart metering concept but lacked in-house hardware or firmware capabilities. Solution-We executed entire industrial design, enclosure design, board and firmware development, DFM review as one full program. Result-A completed and validated prototype was provided on the client's timelines, allowing them a marketable product before establishing an engineering team.
Challenge-The client's existing unit costs were too high, primarily due to complicated enclosure and board assembly. Solution-We reworked the enclosure design to ease fabrication and integrated the board design to simplify manufacturing. Result-We reduced the cost of materials and assembly while maintaining the product's exterior appearance, increasing profit margins on the established product line.
Challenge-The client required a working prototype of their proposed device based on a simple two-page brief, with no prior CAD or electronics work done. Solution-We developed a requirements analysis and subsequently an industrial design, mechanical and electronics design, and firmware development for the product. Result-A working prototype was delivered and demonstrated in the field and to investors within the project constraints.
A well-engineered product needs to be practical to manufacture, assemble, test, and scale. Our engineering team supports the transition from validated designs to production with DFM reviews, prototype refinement, documentation, component considerations, and manufacturing coordination.
Review product designs for manufacturability, assembly requirements, material selection, tolerances, and production constraints.
Evaluate prototype performance and incorporate engineering improvements before moving toward production.
Prepare and refine technical drawings, design files, specifications, and documentation required for manufacturing.
Support component selection, material considerations, and design decisions based on product and manufacturing requirements.
Coordinate engineering requirements with manufacturing partners to help maintain design intent through production.
In a product development sense Design & Engineering is the end-to-end process of turning an idea into something that is producible including industrial design, mechanical design, electronics design, embedded firmware, along with analysis and testing to validate the product before production. Treated as distinct disciplines they are passed between different suppliers which can lead to problems being discovered late, for example an enclosure that is the wrong size for the board, firmware that was written for hardware that is no longer applicable, when treated as a single coordinated process, one team follows the requirements through all stages spotting issues early rather than at the first prototype.
Questions we hear on every design & engineering scoping call — answered directly, without the brochure language.
Concept & industrial design, mechanical design & 3D CAD, electronics & PCB design, embedded firmware design, DFM/DFA review, prototyping and mechanical/thermal analysis from a single in-house engineering team end-to-end.
Yes. The full turnkey product development cycle is a Rhosigma specialty, from concept sketching & industrial design, through mechanical & electronics design, firmware, prototyping and handing off to manufacturing.
No, we work with clients from initial concept and requirements engineering, through concept study before working with CAD or electronics design software.
The complete concept to prototype typically runs 3 to 6 months with mechanical or electronic only engagements taking less time.
Yes, our mechanical and electronic design resources are integrated into the same in-house team, considering physical fit, thermal impact, and electronic interface points together, instead of needing separate vendors for separate pieces of a product.
Yes. We can look into existing products for opportunities in material choice, component costs and DFM, then redesign a product accordingly.
