Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If packages are placed on the load-carrying device using conventional methods, then the picking process can proceed, but gaps arise between individual packages leading to reduced stability and packing density
Solution Approach 1:
The fine positioning device enables packages to self-adjust to optimal positions through automated sliding movements, eliminating gaps and achieving compact packing without manual intervention. The device allows packages to be automatically pushed into correct positions based on the predetermined packing pattern.
Solution Approach 2:
The system changes the positional parameters of packages by using the fine positioning device to slide packages along the load-carrying device. This adjusts the position, orientation, and spacing of packages to eliminate gaps and achieve the desired packing density and stability.
2Stability of the object's composition
If more load-carrying devices are used to compensate for instability, then package stability can be maintained, but the number of devices increases leading to reduced efficiency and higher costs
Solution Approach 1:
The invention extracts and eliminates the problematic gaps between packages using the fine positioning device. By removing these gaps through automated sliding adjustments, the system achieves stable package arrangements without needing additional load-carrying devices, thereby maintaining productivity.
3Productivity
If the picking robot travels at higher speeds, then productivity increases, but package stability deteriorates due to movement and vibration
Solution Approach 1:
The fine positioning device performs preliminary positioning of packages before the picking robot begins high-speed travel. By pre-adjusting package positions and eliminating gaps beforehand, the system ensures package stability is maintained even during high-speed movement and vibration.
4Stability of the object's composition
If manual adjustment of packages is performed to eliminate gaps, then packing stability improves, but setup time and operational complexity increase
Solution Approach 1:
The invention replaces manual mechanical adjustment with an automated fine positioning device that uses sliding mechanisms actuated by motors or other drive systems. This substitution eliminates the need for manual intervention while achieving the same gap-elimination effect, thereby reducing setup time and operational complexity.

Function Achieved in This Case
This solution enables more efficient packing, reducing the need for multiple load-carrying devices, increasing travel and cornering speeds, and improving handling capacity by stabilizing packages during movement, thus optimizing the picking process and reducing setup times.
Implementation Method 1
The sliding device comprises an actuator that is implemented hydraulically, pneumatically, mechanically, or according to a technology known from the prior art. The sliding device allows packages to be pushed onto a counter-bearing
Implementation Method 2
The sliding device allows packages to be pushed onto a counter-bearing, which is designed, for example, as an opposite, fixed wall of the picking robot
