Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional separating mechanism mounted on a linear guide is used, then the structure is simple, but the degrees of freedom are limited and flexibility is low
Solution Approach 1:
The patent replaces the conventional mechanical linear guide system with a robot arm system. The robot arm uses its multi-axis joints and end effector to achieve separating movements, substituting complex mechanical guides with a more flexible robotic system that provides multiple degrees of freedom through its articulated structure.
Solution Approach 2:
The patent introduces dynamic positioning capability by using a robot arm that can adjust its position and orientation in real-time. The robot arm can dynamically adapt to different stack positions and object configurations, providing flexibility through controlled movement in multiple directions rather than being constrained to a fixed linear path.
2Measurement precision
If a conventional separating mechanism is used, then the mechanism is simpler, but the positioning accuracy is lower
Solution Approach 1:
The patent incorporates sensors (such as optical sensors or proximity sensors) that provide feedback on the position of the separating mechanism relative to the object stack. This feedback enables the robot control system to adjust the position and movement of the separating mechanism to achieve precise positioning, ensuring accurate separation operations.
Solution Approach 2:
The patent replaces mechanical positioning systems with a robot arm system controlled by digital signals and sensor feedback. This substitution enables higher positioning accuracy through programmable motion control and real-time adjustment, replacing less accurate mechanical guides and fixed positioning mechanisms.
3Productivity
If a conventional separating mechanism is used, then the structure is less complex, but the separating efficiency is low
Solution Approach 1:
The patent uses a robot arm that can dynamically adjust its speed, position, and movement trajectory to optimize the separating process. The robot arm can accelerate and decelerate smoothly, position itself precisely for each separation action, and adapt its movement pattern to the stack configuration, thereby improving separating efficiency through dynamic control rather than fixed mechanical operation.
Solution Approach 2:
The patent changes the operational parameters of the separating mechanism by using a robot arm that can vary its speed, position, and force application dynamically. This allows optimization of the separating process for different object types and stack configurations, improving efficiency through parameter adjustment rather than being constrained by fixed mechanical parameters.

AI summary
Embodiments of present disclosure relate to an apparatus and a method for separating objects. The apparatus comprises: a separating mechanism configured to separate objects arranged in a stack; a robot configured to hold the separating mechanism; and a controller configured to: cause the robot to move the separating mechanism to a first height; cause the robot to move the separating mechanism towards the stack; in response to a distance between the separating mechanism and the stack reaching a distance threshold, cause the robot to stop moving the separating mechanism; and cause the separating mechanism to separate the objects.
