DOUBLE ELECTRIC FIRE HOSE Roller

The challenge

Design a mobile machine capable of rewinding two fire hoses simultaneously for two operators. The equipment needed to be assembled from separate modular parts for easy customer assembly and compact shipping. It had to ensure uniform rewinding speed, meet strict safety standards, shut off automatically at full rewind, and feature both automatic and mechanical hose ejection systems. Additional requirements included a hose tensioning mechanism, visual indicators for operation, pause, and emergency stop, foot-pedal controls, and the option for emergency shutdown.

The solution

The machine was built on welded steel frames made from square and rectangular tubing, ensuring strength and stability. Rotating components were CNC-machined from aluminum, while the housing was fabricated from sheet aluminum for durability and reduced weight. Speed sensors maintained uniform hose winding, and electro-actuators enabled automatic hose ejection, supported by a backup mechanical system. A controller managed operating modes with clear visual indicators, while the entire mechanism was specifically engineered for effortless assembly using only screws and a screwdriver—making it compact for shipping and quick to put together straight out of the box.

Configurable conference table module

The challenge

Design a modular conference table connectivity module that could adapt to different meeting needs while maintaining a sleek, unified appearance. The unit had to support durability, seamless integration of power and data connections, and allow simple installation or reconfiguration without compromising reliability or aesthetics.

The solution

Developed a flexible, modular connectivity module with interchangeable components and concealed cable management, enabling rapid adaptation to various conference setups. Precision-engineered housings and high-quality plastics ensure rigidity and longevity, while a minimalist design keeps the table surface clean, professional, and clutter-free.

The Pool Tables

The challenge

Design and engineer an 8-foot billiard table based on a concept sketch, ensuring exceptional stability and safety. The table had to support a playing surface weighing 800–850 lbs (363–386 kg) without deflection, maintain a rigid, vibration-free frame under lateral or vertical impact, and meet high aesthetic standards.

The solution

The frame was precision-formed from 1/4" (6.35 mm) aluminum sheet, validated with Finite Element Analysis (FEA) in SolidWorks to ensure zero deflection under load. A welded rectangular aluminum tubing support structure provided maximum rigidity, while a high-quality natural wood finish delivered a refined, elegant appearance.

Credenza open

Sculptural Credenza

The challenge

Design a luxury credenza composed entirely of individual chrome spheres, creating the appearance of a seamless, monolithic piece. The four front doors had to remain completely hidden, while the design had to accommodate over 3,200 spheres with precise assembly tolerances of just 0.005 inches, despite the weight and complexity of numerous fasteners.

The solution

A solid wooden frame veneered with mirrored aluminum provided the structural base, while PVC spheres were injection-molded and finished with a reflective chrome coating. This approach delivered a visually seamless, high-end piece that combined meticulous engineering with striking luxury aesthetics.

Engineering Projects
