Client: Tectrax

Challenge:

We were approached by Tectrax in May of 2017 to assist with the mechanical aspects of their proposed drive system for amphibious boats. In particular the retractable legs that raised and lowered the wheels. The brief given was specific and clear that the preferred design of the front arm would be in a vertical motion. They also had an initial concept of how that would work. 3DM Design’s Initial investigation of this concept revealed the action of the link arms could not create enough vertical movement to raise and lower a boat the required distance.

 3DM Design then proposed a different concept of a double scissor arm linkage that could raise and lower a boat the required distance and still retract into a small envelop when not in use. This required double hydraulic rams that worked to drive a top and lower hinged leg system but ensured the movement of the wheel was in still in a vertical motion.The rear wheel legs were to be a single leg driven by a single hydraulic cylinder.

Requirements:

• CAD Drawings of existing Hub motor and gearbox
• Verification of gear ratios and power outputs
• Detailed design of housing/casing for motor and gearbox
• Design of retractable front legs and deployment system
• Hydraulic steering system
• Design of rear legs for retraction and deployment
• Integration of hydraulics, electrics and control systems.

Successes: 
Tectrax now have a fully operating amphibious system that can be attached to OEM vessels.

Client: Cabrinha Kites

Challenge: Assist with the development of Cabrinhas new Quickloop and Control systems.  The quickloop system is a safety device, which allows the user to de-power their kite in an emergency situation.  The existing system was complicated to reload, and it was desireable to minimise release loads.  In addition to the quickloop, improvements for untwisting kite lines, adjusting kite power, and improving flotation were implemented.

• Simplify operation
• Improve release loads
• Incorporate additional features

Successes: 

• Usability described as "rediculously simple" and is deemed the new industry benchmark
• Unique pin design, maximises the available space to improve release loads
• Product Released July 2014.  Check out the launch video here

Client: Heyrex

Challenge: 

Help Heyrex develop a smaller bowl for small animals (cats, small dogs etc...) with a new modern look and smaller valve and fitration system.

The TORUS™ design is comprised of a water storage area and a drinking well. The bulk of the pet’s water is stored and protected inside the hollow walls of TORUS™. Each time your pet takes a drink, replacement water automatically flows from the storage area into the drinking well.

1. Stored water is contained inside the TORUS™ walls.
2. Fresh water is drawn from the walls through the carbon filter.
3. The filtered water flows out into the drinking well where it is kept at an optimum level.

Successes: 

• Helped refine the design to a new modern look 
• Unique smaller valve and filter system maximises the available space 
• Product Released Nov 2015.  

Client: Wishbone Design Studio

Challenge: To assist with the realisation of Wishbones highly adjustable, recycled plastic balance bike.

• Made from recycled plastic where possible
• Must be adjustable over a huge range, but in small increments to suit children from age 1 to 6
• Maintain the aesthetic of the handmade foam prototypes

Successes: We were able to recreate the organic, handmade prototypes as an engineering CAD model, enabling us to design the rotating height adjustment (Rotafix) mechanism.  We were able to predict material suitability and part performance using FEA, as well as providing high quality animations for marketing purposes.
