Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the blade diameter is increased to produce more power, then the power output is improved, but the manufacturing difficulty and required vehicle height increase
Solution Approach 1:
The gantry system employs wheels instead of fixed support structures, enabling dynamic movement along the blade length. This dynamic configuration allows the system to adapt to varying blade sizes and shapes without requiring reconfiguration of the entire manufacturing platform, thereby reducing manufacturing complexity while maintaining high power output capability
Solution Approach 2:
The gantry system bridges the blade in the cross-section direction (horizontal dimension) rather than requiring a vertically stacked configuration. This dimensional change allows the manufacturing platform to span across the blade width, providing stability and access to large-diameter blades without proportionally increasing vehicle height
2Adaptability or versatility
If the vehicle height is increased to accommodate large blade diameters, then the blade processing capability is improved, but the vehicle footprint and space requirements increase
Solution Approach 1:
The gantry system transitions from a vertical stacking approach to a horizontal spanning approach by bridging the blade in the cross-section direction. This allows the system to accommodate large blade diameters through increased span width rather than increased height, thereby maintaining adaptability while reducing vertical space requirements and footprint
Solution Approach 2:
The wheeled gantry system can dynamically adjust its position and span configuration to match different blade sizes. This dynamic adaptability allows a single system design to handle various blade diameters without requiring proportionally larger footprints, as the system can be positioned optimally for each specific blade geometry
3Device complexity
If manual manufacturing methods are used for large blades, then the equipment simplicity is maintained, but the worker safety and ergonomic conditions deteriorate
Solution Approach 1:
The robotic units perform manufacturing operations autonomously without requiring direct human intervention in hazardous zones. The system serves itself by automatically executing manufacturing steps, thereby eliminating worker exposure to harmful substances while maintaining relatively simple equipment architecture through automation rather than complex safety systems
Solution Approach 2:
Manual mechanical operations are replaced with automated robotic units that can operate in hazardous environments. This substitution removes workers from exposure to hazardous substances while the robotic systems maintain operational simplicity through programmable control rather than requiring complex safety infrastructure
4Manufacturing precision
If automated robotic units are introduced for manufacturing, then the manufacturing precision and safety are improved, but the device complexity increases
Solution Approach 1:
Manual operations are replaced with programmable robotic units that inherently provide higher precision through controlled motion systems. The complexity increase is offset by the elimination of manual positioning and measurement processes, as the robotic system integrates sensing, control, and execution in a unified automated platform that maintains overall system manageability
