Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional stacking devices with multiple plates and counter-rotating turrets are used, then stacking function is achieved, but device complexity increases
Solution Approach 1:
The device is divided into functionally independent modules: a conveying stretch for bag transport, a removal device with vertically movable push-in device for bag pickup, and a stack holding device with buffer storage chute and cartridge storage chute. This modular segmentation simplifies each component's design while maintaining overall stacking productivity.
Solution Approach 2:
The invention extracts the essential stacking function from complex mechanical systems and implements it through a simplified mechanism: a single vertically movable push-in device that raises bags from the conveying stretch and transfers them to the stack holding device, eliminating the need for multiple plates and counter-rotating turrets.
2Area of stationary object
If conventional stacking methods with multiple components are used, then stacking reliability is achieved, but space requirement increases
Solution Approach 1:
The buffer storage chute and cartridge storage chute are integrated into a single stack holding device structure, with the cartridge positioned above the buffer storage. This merging of storage functions into one compact unit reduces the overall footprint while ensuring reliable stacking through coordinated operation of the push-in device between the two chutes.
Solution Approach 2:
The invention utilizes vertical space by arranging the cartridge storage chute above the buffer storage chute, effectively using the vertical dimension to reduce horizontal space requirements. The vertically movable push-in device operates in this vertical arrangement to transfer bags between levels.
3Ease of operation
If conventional conveying and stacking systems are used, then bag transfer function is achieved, but ease of operation deteriorates
Solution Approach 1:
The vertically movable push-in device automatically performs the bag transfer operation by raising bags from the conveying stretch and placing them into the stack holding device. The system operates autonomously without requiring manual intervention for bag handling, improving ease of operation while maintaining simplicity through the single push-in device mechanism.

Data Source
AI summary
A method and a device for forming stacks of packages by stacking infusion bags is disclosed. In one example, the method includes removing an individual infusion bag from a conveying stretch, on which individual infusion bags are fed, to a removal station. The individual infusion bags, guided by a vertically movable push-in device in a stacking stroke of said push-in device, are transferred into a buffer storage chute of said stack holding device. In a transfer stroke of said push-in device, which is greater than said stacking stroke, an infusion bag completing said stack of packages is raised off of said conveying stretch and transferred into a cartridge storage chute of said stack holding device.
