Resource and material efficiency 6.5 Simplified ecological life cycle assessment Life cycle assessments can be used to calculate how high the envi- ronmental impact of products is in various environmental impact categories. In the past, we approached the complexity of environ- mental impact categories through the establishment of a simpli- fied ecological life cycle assessment (LCA), which allows the CO 2 footprint of the product to be calculated via the bill of materials in the early phases of product development. In order to integrate such a calculation logic into standardised cor- porate processes, further projects and measures were set up on this topic in 2020. More and more customer enquiries are reaching Festo regarding the CO 2 footprint of its own products (cradle-to- gate). The graphs below show an internally calculated CO 2 footprint for the solenoid valve VUVS, the solenoid valve MVH and the adaptive mould gripper DHEF. 6.6 Lightweight construction as an interdisciplinary cross-sectional topic Lightweight construction must be taken into account as a cross-sectional topic in the early phases of product development. In addition to lightweight functional design and well-thought-out functional integration during the design of the functional structure, lightweight material design and lightweight mould design as well as lightweight manufacturing design are important elements that must be taken into account during systematic product develop- ment according to VDI 2221. It is important that the development engineers reduce themselves to the essentials as much as possible. This leads directly to the fact that – in addition to the standard market products – new prod- ucts can emerge that no longer fulfil all the functions that our cus- tomers are used to, but which are lighter and cheaper. Much there- fore also depends on the mindset of the client: in order to achieve a CO 2 reduction through lightweight construction within the mean- ing of sustainability, we as a component supplier are dependent on the machine and plant manufacturers, who should also specifically focus on lightweight purchasing. Adaptive shape gripper DHEF An example of lightweight construction at the functional level and resource efficiency in general is the adaptive shape gripper DHEF, which was launched in 2019. The elastic silicone cap of the gripper slips over almost any grip- ping object with the help of compressed air and spring force. This creates a tight form fit and the flexible silicone adapts precisely to many different geometries. The great advantage here is that the gripper can replace a complex mechatronic system in a very simple way, with additional functions at the same time. The gripper can grip, collect and release a high variety of workpieces with different shapes without the need for manual conversion during operation. When combined with a pneu- matic drive, the adaptive mould gripper also grips safely and with low energy consumption. Learning from nature The operating principle of the adaptive gripper DHEF follows the function of the chameleon’s tongue, which is placed over the respective prey animal during the hunt and encloses it securely and firmly. The unique combination of force and form closure of the tongue was utilised by the Festo Bionic Learning Network with researchers from the University of Oslo in the development of a prototype under the name ‘FlexShapeGripper’, which was subsequently fur- ther developed into the series product DHEF.
