Disassembly Procedure Generation Using Assembly Work Element Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for generating disassembly and replacement procedures are inefficient and lack usability for service technicians, as they do not effectively convert assembly procedures into usable disassembly or replacement steps, nor do they accurately identify faulty parts or calculate comprehensive costs.
Innovation Solution
A computer-based system that generates disassembly and replacement procedures by inserting new work elements into assembly procedures, using databases to associate work elements of assembly and disassembly procedures, and calculates total costs, displaying both procedures alongside their costs for improved usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If assembly procedures are converted into disassembly procedures using existing database methods, then disassembly procedures can be generated, but the procedures lack usability for service technicians and do not accurately reflect actual disassembly steps
Solution Approach 1:
The system performs preliminary actions by inserting new work elements into the assembly procedure before conversion, and by pre-associating work elements of assembly procedures with corresponding work elements of disassembly procedures in the database. This ensures that when disassembly procedures are generated, they already contain the necessary detailed steps and cost information needed for usability by service technicians.
2Productivity
If replacement procedures are generated by referring to error code databases, then replacement procedures can be identified, but the system cannot accurately identify faulty parts or calculate comprehensive replacement costs
Solution Approach 1:
The system uses feedback by monitoring whether new work elements have been inserted into the assembly procedure, and by using this information to generate updated disassembly procedures. The cost calculation feedback loop calculates costs for individual work elements and aggregates them to provide comprehensive replacement cost information, ensuring accuracy in faulty part identification and cost estimation.
3Ease of operation
If detailed work elements are added to assembly procedures to improve disassembly procedure quality, then usability improves, but the complexity of procedure generation and cost calculation increases
Solution Approach 1:
The system uses an intermediary approach by introducing a monitoring mechanism that tracks new work element insertions, and by using cost information as an intermediary to bridge assembly and disassembly procedures. The monitoring step acts as an intermediary between procedure creation and conversion, ensuring that detailed work elements are properly captured without overwhelming system complexity.
