Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a complex structure is used to support the camera, then the support stability is improved, but the operation becomes tedious and device complexity increases
Solution Approach 1:
The patent combines multiple locking mechanisms (upper locking mechanism with swing bolt and eccentric rod, lower locking mechanism with tightening wedge block and locking block) into a single integrated system controlled by one pulling handle. This merging of functions allows the operator to control both joints simultaneously, improving ease of operation while maintaining support stability through the coordinated action of both locking mechanisms.
Solution Approach 2:
The single pulling handle serves multiple functions: it controls the upper locking mechanism through the swing bolt and eccentric rod, and simultaneously controls the lower locking mechanism through the connection rod and tightening wedge block. This multi-functionality reduces the number of separate controls needed, making operation more convenient while maintaining stable camera support.
2Measurement precision
If multiple locking mechanisms are used to control different joints, then the positioning precision is improved, but the device complexity and number of components increase
Solution Approach 1:
The patent integrates two separate locking mechanisms (upper and lower) into a single control system operated by one pulling handle. The upper locking mechanism uses a swing bolt and eccentric rod, while the lower uses a tightening wedge block and locking block, but both are controlled through the same handle, reducing operational complexity while maintaining precise positioning of both joints.
Solution Approach 2:
The pulling handle core rotates around a shaft axis of the swinging shaft, and the eccentric rod and eccentric boss shaft convert this rotational motion into linear motion of the swing bolt and tightening wedge block. This dynamic conversion allows a single rotational input to control multiple locking points, achieving precise positioning without requiring separate controls for each joint.
3Ease of operation
If a single pulling handle is used to control both joints, then the ease of operation is improved, but the reliability of individual locking mechanisms may be compromised
Solution Approach 1:
The patent combines two independent locking mechanisms into one integrated system controlled by the pulling handle. The upper locking mechanism with swing bolt and eccentric rod operates independently from the lower locking mechanism with tightening wedge block and locking block, but both respond to the same control input. This design maintains reliability through redundancy while improving ease of operation through unified control.
Solution Approach 2:
The pulling handle core acts as an intermediary that translates a single user input into coordinated action of both locking mechanisms. The eccentric rod and eccentric boss shaft serve as intermediate elements that convert the rotational motion of the handle into the linear motion required by both locking systems, ensuring reliable and synchronized operation of both joints.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables efficient and comfortable operation with a single pulling handle, allowing for precise control of camera positioning, enhanced durability, and improved user experience through magnetic attraction and adjustable locking forces.
Implementation Method 1
The fixed part is provided with a magnetic latch device... every two of the first sliding frame, the second sliding frame and the third sliding frame are in butt joint due to attracting of the magnetic blocks
Implementation Method 2
an axis of the eccentric rod deviates from an axis of the swinging shaft, and eccentric rotation of the eccentric rod enables the swing bolt to do push-pull movement
Implementation Method 3
one surface, making contact with the locking block, of the tightening wedge block is a bevel, one surface, making contact with the tightening wedge block, of the locking block is also a bevel, the bevel of the tightening wedge block in the upward moving process can push the locking block to move transversely in the groove
