Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional rigid connections are used between carrier receivers and carrier beam, then structural strength is improved, but safety deteriorates due to unsafe load distribution and risk of point loads
Solution Approach 1:
The patent applies the dynamics principle by replacing rigid fixed connections with hinged connections between the carrier receivers and the carrier beam. This allows the connection to adapt dynamically to height differences and load variations, transforming the system from static to dynamic. The hinged connection enables rotation and adjustment, preventing unsafe load distribution and point loads while maintaining structural integrity during lifting operations.
2Device complexity
If fixed carrier receivers are used, then device complexity is reduced, but adaptability deteriorates due to inability to compensate for height differences
Solution Approach 1:
The hinged connection introduces dynamic adaptability without significantly increasing device complexity. The hinge mechanism is a simple mechanical element that allows the carrier receivers to adjust to height differences and uneven ground conditions, enabling the lifting device to adapt to various vehicle types and lifting scenarios while maintaining a relatively simple overall structure.
3Reliability
If hinged connections are used between carrier receivers and carrier beam, then safety is improved by preventing point loads, but device complexity increases
Solution Approach 1:
The hinged connection provides safety through dynamic load distribution, allowing the system to accommodate height differences and prevent point loads. The hinge mechanism is a simple, well-understood mechanical element that adds minimal complexity while significantly improving safety by enabling automatic load balancing and preventing structural failure from uneven load distribution.
