Acetabular Cup

Lightweight design for personalized medical treatment.

Artificial acetabular cups are often used as implants for hip replacement. A lightweight acetabular cup with enough load bearing capability is desirable for patients. With the help of generative design technique, acetabular cups with optimized topology can be designed which has a similar weight and mechanical property with the original one. Besides, the surface of the optimized acetabular cup presents a porous feature which can facilitates bone growth.

Medical Splint

Lightweight design for personalized medical treatment.

Medical splints are commonly used to treat fracture in clinical treatment. However, the traditional splint made by gypsum or plastic is bulky, heavy and discomfort. Changing dressing is hard and the skin is easy to be allergic with the traditional splint.

With the generative design method, a newly lightweight splints can be designed to overcome the shortcomings in the traditional splints. The new splints are customized with the help of 3D scan and additive manufacturing, mechanical properties of which are guaranteed by biomedical analysis and intelligent algorithm. A 50% weight reduction can be achieved in the new splints comparing to the traditional one. Besides, porous surface in the new splints increase the breathability of the structure, making patients more comfortable.

Exoskeleton

Lightweight design for personalized medical treatment.

A lower limb exoskeleton is often used to assist walking for a patient with injured foot, which can transform the loads directly from road into leg without injuring the wounded foot. However, traditional exoskeletons with heavy weight make patients walk painfully and uncomfortably. With the generative design technique, a lightweight and porous lower limb exoskeleton design can be realized. The strength and stiffness of the optimized exoskeleton are ensured by biomedical analysis and the comfort of the patient is preserved at the same time.

Steering Knuckle

Lightweight design for automotive industry.

The endurance mileage and energy saving capability are two key indexes for new energy car. Structural lightweight design is one of the most important ways to improve above performance. With the generative design technique, a steering knuckle with lightweight cellular infills can be realized, which has a weight reduction of 30% comparing to the traditional design. Besides, an excellent impulsive load bearing capability, enough strength and stiffness are processed in the new steering knuckle.

Welding Robot

Lightweight design for manufacturing facilities.

Lightweight design is essential for welding robots to increase the response speed and to decrease the energy consumption. With the generative design technique, 20%-35% weight reduction can be realized in the topology optimized robot arm. A lightweight lattice pattern with the advantage of high strength-to-weight ratio is utilized to replace the original bulky structure. The stiffness and the strength of the optimized robot arm both satisfy the design requirements. Besides, the response speed for the welding robot can be increased with the optimized lightweight robot arm and the total energy consumption is decreased.

Vehicle Chassis

Lightweight design for vehicle engineering.

Energy saving and increasing the endurance mileage are key objectives for the new energy vehicle industry. Structural lightweight design is one of the most important ways to achieve above objectives.

With the generative design technique, a lightweight automotive chassis with optimized topology for a new energy vehicle can realized with a weight reduction of 15%-30% comparing to the traditional design. Mechanical properties e.g. strength, stiffness of the optimized chassis satisfy the design requirements. A larger endurance mileage and a larger loading capability can be achieved with the optimized chassis design.
