Automated Ideation in CAD: From Prior Art to Novel Concepts
Category: Modelling · Effect: Strong effect · Year: 2019
Leveraging TRIZ principles within a CAD framework can automate the generation and evaluation of design concepts from existing models.
Design Takeaway
Designers can explore integrating TRIZ principles and computational tools into their ideation workflows to systematically generate and evaluate novel design concepts from existing product data.
Why It Matters
This approach can significantly accelerate the early stages of the design process, moving beyond manual modification of existing designs to systematically explore novel solutions. By integrating ideation with CAD and decision-making tools, design teams can more efficiently identify and develop high-value concepts.
Key Finding
A new computational method has been developed that uses existing 3D CAD models and the Theory of Inventive Problem Solving (TRIZ) to automatically generate and evaluate new design ideas, presenting them as CAD models.
Key Findings
- A method for automated ideation and concept development using TRIZ, CAD, and MCDM was developed.
- The integration of these tools enables the transformation of existing designs into novel concepts.
- An automated method for reducing CAD model complexity was proposed.
Research Evidence
Aim: Can TRIZ principles be integrated with CAD and Multi-Criteria Decision Making (MCDM) to automate the ideation and concept development stage, transforming existing 3D CAD models into novel design concepts?
Method: Computational Modelling and Algorithmic Design
Procedure: The method involves creating a function model from a prior art CAD design, simplifying it to generate new function models, and then using MCDM to quantitatively evaluate and select the most promising new designs. This is supported by an automated CAD model complexity reduction technique.
Context: Computer-Aided Design (CAD) software development and engineering design processes.
Design Principle
Systematic innovation can be achieved by applying structured problem-solving methodologies (like TRIZ) within digital modelling environments to generate and evaluate design alternatives.
How to Apply
Develop or utilize CAD plugins that incorporate TRIZ tools to suggest design modifications or generate variations based on an initial model. Implement MCDM frameworks to objectively compare generated concepts.
Limitations
The effectiveness of the automated ideation is dependent on the quality of the input model and the TRIZ principles applied. The MCDM process requires careful definition of criteria and weights.
