Manufacturing State Visualization for Assembly Sequence Planning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing manufacturing process planning systems fail to accurately represent the assembly sequence and do not allow for variability in tasks or resources, leading to conflicts and costly rework, and lack the ability to reuse manufacturing views across different contexts.
Innovation Solution
A method and system for defining and storing manufacturing states at different time periods in a process database, allowing for the visualization of manufacturing contexts across multiple installation plans, enabling holistic context establishment and reducing redundant work.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manufacturing states are stored in a process database for reuse across multiple installation plans, then productivity and reduction of redundant work improve, but device complexity increases due to the need for database management and state retrieval systems
Solution Approach 1:
The process database stores manufacturing states that can be reused across multiple installation plans and different manufacturing contexts. A single manufactured state (e.g., a wire harness assembly state) can be referenced by multiple installation plans, eliminating the need to recreate the same states repeatedly and enabling universal application of manufacturing knowledge across different projects.
Solution Approach 2:
The system creates digital copies of manufacturing states and stores them in the process database. These copied states can then be retrieved and used in different installation plans without physically recreating the manufacturing context, allowing efficient replication of manufacturing knowledge across multiple projects and reducing redundant work.
2Measurement precision
If manufacturing contexts are visually displayed across multiple installation plans, then measurement precision and contextual understanding improve, but information overload and difficulty of detecting and measuring increase
Solution Approach 1:
The visual display system presents manufacturing contexts with localized detail - showing specific manufacturing states and their attributes only where relevant to each installation plan. The display adapts the level of detail based on the specific context being viewed, preventing information overload by showing only the necessary local information rather than all possible data at once.
Solution Approach 2:
The manufacturing context information is segmented into discrete, manageable units representing different manufacturing states. Each state is a separate entity that can be individually displayed and analyzed, allowing the system to break down complex manufacturing processes into comprehensible segments that can be visually presented without overwhelming the user.
3Adaptability or versatility
If manufacturing states are defined at different time periods, then adaptability and representation of process evolution improve, but device complexity increases due to temporal state management
Solution Approach 1:
The system dynamically manages manufacturing states across different time periods, allowing the manufacturing context to evolve and change over time. The process database stores states at various temporal points, enabling the system to adapt to different stages of manufacturing and retrieve appropriate historical states when needed, providing flexibility in representing process evolution.
Solution Approach 2:
The system pre-defines and stores manufacturing states at different time periods in advance, before they are needed for specific installation plans. By preparing these temporal states beforehand and organizing them in the process database, the system eliminates the need for complex real-time state creation and management during actual manufacturing operations.

AI summary
A system and method of using manufacturing states in a manufacturing process is provided in which manufacturing states for an article of manufacture are defined at different time periods of a manufacturing process for display as manufacturing contexts relating to an installation plan. The manufacturing states for the article of manufacture are stored in a process database as the manufacturing states are defined during the manufacturing process. The manufacturing contexts relating to the installation plan for the article of manufacture are visually displayed with at least one other manufacturing context relating to another installation plan for another article of manufacture.
