Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed configuration conveyance system is used, then the system structure is simple, but it cannot accommodate multiple vehicle models
Solution Approach 1:
The gripping parts are designed to be adjustable in width, allowing the conveyance system to adapt to different vehicle model dimensions. The control part dynamically adjusts the gripping part configuration based on the detected vehicle model, enabling a single system to handle multiple vehicle types without requiring fixed dedicated configurations for each model
Solution Approach 2:
The system changes the physical parameters of the gripping parts (width and position) according to the vehicle model being conveyed. The control part modifies these parameters dynamically, allowing the same hardware to serve multiple purposes across different vehicle models, thereby improving adaptability without proportionally increasing system complexity
2Manufacturing precision
If positioning pins are used for each work station, then positioning precision is improved, but the system cannot easily switch between different vehicle models
Solution Approach 1:
The positioning pins are designed as universal components that can be used across multiple work stations and different vehicle models. Rather than having model-specific positioning pins, the system uses a set of standardized positioning pins that work with various vehicle types, maintaining positioning precision while enabling multi-model applicability
Solution Approach 2:
The positioning pin configuration is dynamically adjusted based on the vehicle model. The control part selects and positions appropriate pins according to the detected vehicle type, allowing the same physical pins to serve different positioning requirements for various models, thereby achieving both precision and adaptability
3Productivity
If manual adjustment of gripping parts is used, then system complexity is reduced, but conveyance efficiency and positioning accuracy decrease
Solution Approach 1:
The system performs self-adjustment of the gripping parts through automated control. The control part automatically detects the vehicle model and adjusts the gripping part width and position without requiring manual intervention, thereby improving conveyance efficiency and positioning accuracy while managing system complexity through automation
Solution Approach 2:
The control part uses feedback from vehicle model detection to automatically adjust gripping part parameters. This closed-loop control ensures accurate positioning and efficient conveyance by continuously adapting to the specific vehicle model being handled, improving productivity while maintaining manageable system complexity through intelligent control

AI summary
A vehicle body conveyance system includes: an unmanned carrier conveying a vehicle body between multiple work stations; and a positioning pin standing on a work station. The unmanned carrier is provided with a driving part, a pair of gripping parts, a lifting part, and a control part. The control part is configured to: control the gripping parts, so that a left-right width between the pair of gripping parts fits a left-right width between a pair of side sills of the vehicle body, control the lifting part to lift up the vehicle body to separate the positioning hole of the vehicle body from the positioning pin; control the driving part to move the unmanned carrier to another work station, and control the lifting part to lower the vehicle body to insert the positioning hole through the positioning pin standing on the another work station.
