Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual disassembly and assembly method is used, then flexibility and adaptability are maintained, but time consumption and labor intensity increase significantly
Solution Approach 1:
The patent replaces manual mechanical operations with an automated robotic system comprising a robotic arm, drivers, and working members. The robotic arm executes pre-programmed trajectories to perform disassembly and assembly operations, substituting human mechanical actions with automated mechanical systems controlled by computer programs, thereby increasing productivity while managing complexity through automation.
Solution Approach 2:
The automated system performs disassembly and assembly operations independently without requiring human intervention during the actual operations. The robotic arm autonomously positions working members, applies forces, and completes tasks based on pre-programmed sequences, enabling the system to serve itself and eliminating the need for continuous human oversight, thus improving productivity.
2Reliability
If multiple people cooperate manually for disassembly and assembly, then complex operations can be performed, but safety risks increase due to pressurizing materials
Solution Approach 1:
The robotic arm and working members serve as intermediaries between the operator and the pressurizing materials. By introducing this automated intermediary system, direct human contact with hazardous pressurizing materials is eliminated, thereby improving safety. The intermediary executes all operations that would otherwise require human hands to be near or in contact with dangerous substances.
Solution Approach 2:
Manual mechanical operations involving pressurizing materials are replaced with automated robotic mechanical operations. The robotic system performs all mechanical actions remotely, substituting human mechanical interactions with automated ones, thereby eliminating safety risks associated with direct human exposure to pressurizing materials while maintaining operational capability.
3Loss of time
If traditional manual method is used, then equipment complexity is low, but time consumption and labor intensity are high
Solution Approach 1:
The system performs preliminary programming and trajectory planning before actual disassembly and assembly operations. The robotic arm's path, the sequence of operations, and the positioning of working members are all pre-configured, allowing the system to execute tasks efficiently without real-time decision-making delays, thereby reducing overall task time despite the complexity of the automation system.
4Ease of operation
If automated robotic system is implemented, then productivity and safety are improved, but device complexity increases
Solution Approach 1:
The robotic system operates autonomously based on pre-programmed instructions, performing all disassembly and assembly tasks without requiring continuous human intervention or complex real-time control. The system serves itself by executing predetermined sequences, which simplifies the operational interface and makes the system easier to operate despite its internal complexity.
