Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual intervention and cranes are used for disassembly, then the disassembly can be performed, but the risk of injury to personnel and damage to equipment increases
Solution Approach 1:
The disassembly tool is designed to perform the disassembly operation autonomously without requiring manual intervention. The tool self-positiones on the connecting member and automatically executes the disassembly process, eliminating the need for personnel to manually handle the blade segments during disassembly.
Solution Approach 2:
A disassembly tool acts as an intermediary device between the blade segments and the disassembly operation. This tool engages with the connecting member and facilitates the separation of blade segments without requiring direct manual handling, thereby reducing safety risks while maintaining operational capability.
2Productivity
If manual intervention and cranes are used for disassembly, then the disassembly can be performed, but the efficiency and cost increase
Solution Approach 1:
The disassembly tool is designed as a modular device with distinct functional components: a positioning device for locating the connecting member, a guiding device for directing removal motion, and a support structure. This segmented design enables efficient disassembly operations while keeping individual components relatively simple and manageable.
Solution Approach 2:
The disassembly tool serves as an intermediary mechanism that simplifies the overall disassembly process. By introducing this specialized tool, the system replaces complex crane operations with a more straightforward, tool-based approach that improves efficiency without requiring excessively complex equipment.
3Ease of operation
If the connecting member is removed without guidance, then the removal can be performed, but the mobility of the connecting member increases causing safety risks
Solution Approach 1:
The guiding device acts as an intermediary element between the connecting member and the removal operation. It provides a guided path for the connecting member during extraction, maintaining necessary control and stability while still allowing the removal to proceed. This eliminates uncontrolled mobility while preserving the ability to perform the disassembly operation.
Solution Approach 2:
The guiding device provides localized guidance and constraint specifically at the critical interface where the connecting member is being removed. This targeted approach maintains control where needed (during extraction) while allowing freedom of movement elsewhere in the system, achieving the balance between control and operational flexibility.
