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 load distribution safety deteriorates due to height differences between lifting devices
Solution Approach 1:
The patent applies the dynamics principle by replacing rigid fixed connections with hinged connections between the carrier receivers and carrier beam. This allows the structure to adapt dynamically to height differences between lifting devices, enabling automatic load redistribution while maintaining structural integrity during lifting operations.
Solution Approach 2:
The patent changes the connection parameter from rigid to hinged, allowing angular adjustment between carrier receivers and carrier beam. This parameter change enables the system to accommodate vertical position variations of lifting devices while maintaining safe load distribution through controlled mechanical movement.
2Ease of manufacture
If fixed rigid crossbeam structure is used, then manufacturing simplicity is improved, but adaptability to different lifting scenarios deteriorates
Solution Approach 1:
By introducing hinged connections instead of rigid welds or bolts, the crossbeam gains adaptive capability while maintaining relatively simple manufacturing processes. The hinged joints allow the structure to adjust to various lifting configurations and height differences without requiring complex adjustable mechanisms.
3Stability of the object's composition
If carrier receivers are rigidly connected to carrier beam, then structural stability is improved, but risk of point loads and load peaks increases
Solution Approach 1:
The hinged connection creates a dynamic system that can redistribute loads in real-time based on the actual positions of lifting devices. When height differences occur, the hinges allow rotational adjustment that prevents concentration of forces at single points, thereby eliminating harmful point loads while maintaining overall structural stability.
Solution Approach 2:
The hinged connection acts as a pre-designed protective mechanism that cushions against improper load application. Before harmful point loads can develop, the hinge allows controlled movement that redistributes forces, preventing the formation of dangerous load peaks that could compromise structural integrity.
