3D Manufacturing Process Planning via Visual Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current manufacturing process planning methods rely on abstract text-based descriptions, which are less intuitive and require validation, making it difficult for users to accurately define and verify manufacturing processes, especially when dealing with complex products.
Innovation Solution
A method that uses graphical representations of three-dimensional interactions to describe and define manufacturing processes, providing users with visual feedback, allowing them to interact with product parts as they would in the real world, thereby making the process more intuitive and reducing the need for validation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If text-based descriptions are used to describe manufacturing processes, then the process planning can be completed, but the intuitiveness and ease of verification deteriorate
Solution Approach 1:
The patent transitions from two-dimensional text-based descriptions to three-dimensional graphical representations of manufacturing processes. Users interact with 3D models of parts and processes, allowing them to visually define and verify manufacturing steps by manipulating spatial representations rather than interpreting abstract text, thereby improving both intuitiveness and verification accuracy
Solution Approach 2:
The patent creates visual copies of the actual manufacturing process through graphical representations that mirror real-world operations. These graphical models serve as accurate replicas of the physical manufacturing process, allowing users to verify process correctness by comparing the graphical representation against the intended real-world operation
2Ease of manufacture
If text-based descriptions are used for manufacturing processes, then the process can be documented, but the complexity and abstract nature increase
Solution Approach 1:
The system automatically generates process descriptions and documentation from the graphical interactions. When users manipulate 3D representations to define manufacturing steps, the system self-generates the corresponding process documentation, eliminating the need for users to manually create text descriptions and reducing the perceived complexity of the process definition task
3Measurement precision
If visual feedback is provided in graphical form, then the intuitiveness improves, but the system complexity increases
Solution Approach 1:
The patent merges the process definition interface and the verification display into a single integrated graphical environment. The same 3D graphical representation that users interact with for defining processes also serves as the verification medium, eliminating the need for separate verification systems and reducing overall system complexity while maintaining high verification precision

AI summary
Manufacturing process planning is usually considered as not intuitive for non-expert user. This is because a user needs to deal with processes, describing a work to be done, and other abstract concepts that are loosely related to the real world. Accordingly, a method and corresponding apparatus according to an embodiment of the present invention are provided to describe a work to be done in response to a user interacting with a three-dimensional representation of one or more parts that form a product and to provide the user with feedback in the form of a graphical representation of the work to be done. This approach is very intuitive as it is close to how a user would, for example, in a real world, decompose a product into sub-assemblies that essentially results into a definition of a manufacturing process of the product.
