Engineering Contradiction Analysis
1Area of stationary object
If a conventional conveying device with arms suspended between columns or a crossbar extending along the entire length of pressing devices is used, then the conveying function is achieved, but the installation space becomes large and complex
Solution Approach 1:
The conveying robot is divided into modular components: a rotating base with a first arm, a second arm with linear movement capability, and a wrist unit with multiple rotational shafts. This segmentation allows each component to be optimized independently and assembled in a compact configuration, reducing overall installation space while maintaining conveying functionality.
Solution Approach 2:
The patent utilizes three-dimensional spatial arrangement by positioning the rotating base, first arm, second arm, and wrist unit in a vertically and horizontally integrated configuration. The first arm rotates about a horizontal axis while the second arm provides linear movement, creating a compact 3D workspace that reduces the footprint compared to conventional planar conveying devices.
2Speed
If the conveying robot uses a compact configuration with rotating base and articulated arms, then the installation space is reduced, but the conveying speed may be limited by mechanical constraints
Solution Approach 1:
The conveying robot employs dynamic motion capabilities through the rotating base that can rotate about a horizontal axis, the first arm that can swivel about an orthogonal axis, and the second arm that can move linearly. These dynamic components allow high-speed positioning and conveying operations within a compact space, achieving both speed and space efficiency.
Solution Approach 2:
The wrist unit with multiple rotational shafts provides multi-functional capability, enabling the end effector to achieve various orientations and positions. This universality allows a single compact robot structure to perform multiple conveying tasks at high speed without requiring additional specialized mechanisms.
3Speed
If the first arm is disposed to move in a pendulum-like motion about a horizontal axis, then the conveying speed is increased, but interference with peripheral devices may occur
Solution Approach 1:
The patent positions the movement range of the first arm locally within or below a horizontal plane, creating a defined spatial boundary for the pendulum-like motion. This localized positioning ensures high-speed conveying while preventing interference with peripheral devices by confining the motion to a specific zone.
Solution Approach 2:
By disposing the movement range in or below a horizontal plane rather than extending vertically or horizontally beyond it, the patent utilizes vertical space efficiently. This dimensional arrangement allows pendulum-like high-speed motion while keeping the horizontal footprint compact and non-intrusive to surrounding equipment.
