VDI 6224 Blatt-3 2017-09 PDF

Full title and description

STB VDI 6224 Blatt‑3 2017‑09 — German: "Bionik - Bionische Strukturoptimierung im Rahmen eines ganzheitlichen Produktentstehungsprozesses"; English: "Biomimetics - Integrated product development process for biomimetic optimisation". This guideline defines a systematic, step‑wise product development process that applies biomimetic principles and natural archetypes to the structural lightweight optimisation of technical components, and presents the ELiSE process as an example workflow for biomimetic structural optimisation.

Abstract

The document specifies a complete product development procedure for designing and optimising lightweight, load‑bearing structures inspired by biological models. It describes the sequence of work steps — technical description and requirements, screening of biological archetypes, bio‑inspired concept generation, technical concept optimisation (including FEM/evolutionary approaches) and final validation — with attention to manufacturing constraints, static/dynamic and crash loads, and homogeneous stress distribution. The guideline is intended to help reduce weight and increase component lifetime by transferring natural optimisation principles into technical design.

Scope

The guideline addresses the application of biomimetic methods within a holistic product‑development process aimed at structural lightweight design. It is focused on methods to increase stiffness and minimise stresses while accounting for technical boundary conditions and manufacturing restrictions. The described workflow is transferable in principle to other technical problem domains, but the primary emphasis is on structurally optimised, load‑bearing components subject to static, dynamic and crash loads. Annex material includes information on intellectual property considerations related to biomimetic solutions.

Key topics and requirements

• Definition of a stepwise, integrated product‑development process for biomimetic optimisation (technical analysis → biological screening → bio‑inspired concept development → optimisation → validation).
• Use and examples of the ELiSE process as a structured method for bionic structural optimisation.
• Guidance on selecting and screening natural archetypes and transferring functional principles to technical concepts.
• Integration of computational optimisation techniques (including evolutionary algorithms and topology/shape optimisation) with manufacturing constraints.
• Focus on achieving homogeneous stress distribution, minimised material use, and consideration of static/dynamic and crash loading conditions.
• Practical application examples and discussion of how manufacturing processes influence optimisation outcomes.

Typical use and users

Intended users are engineers and technical specialists working in product development, structural design, CAE/FEA, process optimisation and project management across industries that require lightweight, load‑bearing components (automotive, aerospace, mechanical engineering, industrial design). The guideline is used as a process reference to integrate biomimetic ideas and computational optimisation into the product‑development lifecycle.
