Manufacturing Design Dependency Analysis for Change Propagation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In complex manufacturing systems, multiple design processes are often interdependent, leading to rework and delays due to the need for adjustments among design processes such as mechanism, electrical, and control designs, which current technologies fail to efficiently manage.
Innovation Solution
A manufacturing system design assistance apparatus that integrates design information from various processes, analyzes dependencies, and notifies relevant processes of required changes, thereby reducing rework.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple design processes are responsible for designing the manufacturing system, then the manufacturing system can be designed with specialized expertise, but the design processes become interdependent and require adjustment among themselves, causing rework and delays
Solution Approach 1:
The system automatically detects design changes in one process and provides feedback to other affected processes through the design information integrated management unit. This feedback mechanism notifies relevant design processes of changes and their impacts, enabling timely adjustments without manual coordination and reducing overall design cycle time.
Solution Approach 2:
The design information integrated management unit acts as an intermediary between multiple design processes. It centrally manages design information, detects changes, and coordinates adjustments among processes, eliminating the need for direct manual communication between designers and reducing rework caused by lack of coordination.
2Adaptability or versatility
If multiple design processes are responsible for designing the manufacturing system, then comprehensive design coverage is achieved, but adjustment among design processes is required which causes rework in design
Solution Approach 1:
The system automatically detects design changes and provides feedback to affected processes, reducing the complexity of manual coordination. Designers receive automated notifications about changes in related processes, making the adjustment process more manageable and reducing rework.
Solution Approach 2:
The design information is segmented and managed by specific design processes (mechanism design, electrical design, control design), while the integrated management unit coordinates between them. This segmentation maintains specialized expertise while the integration layer simplifies adjustment coordination.
3Manufacturing precision
If design changes are made in one process, then the design can be optimized, but other design processes may be affected requiring notification and adjustment
Solution Approach 1:
The system automatically detects design changes and provides feedback to other affected processes. When a designer optimizes a component, the system automatically notifies other processes that may be affected by this change, ensuring no critical information is lost and coordination is maintained.
Solution Approach 2:
The design information integrated management unit serves as an intermediary that captures design change information and distributes it to relevant processes. This ensures comprehensive information flow about design optimizations and their potential impacts across the system.

AI summary
A plurality of pieces of design information created in the respective design processes and dependencies among the plurality of pieces of design information are stored. A piece of design information to be changed by a piece of design information that is input is extracted from the plurality of pieces of design information. The piece of design information is combined with the plurality of pieces of design information. An influence of the piece of design information on one or more pieces of design information other than the piece of design information to be changed is analyzed based on the dependencies, and it is determined whether the piece of design information is required to be changed. The design process is notified of a request for change of the piece of design information when it is determined that the piece of design information is required to be changed.
