Staggered Container Pack Rigidity via Asymmetric Rearrangement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging systems for cylindrical containers, such as bottles and cans, face challenges in maintaining stability and efficiency when forming matrix packs, often leading to deformation and container escape due to insufficient rigidity, and require complex mechanical systems for staggered arrangements.
Innovation Solution
A packaging installation that uses retractable pushers and guide walls to rearrange containers into staggered rows, allowing for the creation of additional columns and ensuring all containers are in contact, simplifying the process and adapting to any packaging machine, without the need for precise column control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If containers are arranged in a matrix formation, then the packaging structure is simple and regular, but the pack rigidity becomes insufficient and containers may escape
Solution Approach 1:
The patent applies asymmetry by transitioning from a symmetric matrix arrangement to an asymmetric staggered arrangement where containers are offset by half a diameter between rows. This asymmetric positioning increases the number of contact points between containers from 4 to 6, thereby enhancing pack rigidity and stability while maintaining manufacturing simplicity.
2Stability of the object's composition
If containers are arranged in staggered rows to improve rigidity, then pack stability increases, but the packaging process becomes more complex
Solution Approach 1:
The patent employs self-service by allowing containers to automatically form staggered rows through their own interaction and contact with neighboring containers during the packaging process. The containers naturally settle into the staggered configuration with 6 contact points each, eliminating the need for complex mechanical positioning systems or additional guiding mechanisms.
3Stability of the object's composition
If containers are arranged in staggered rows with optimized column distribution, then pack compactness and rigidity are maximized, but the arrangement control becomes more difficult
Solution Approach 1:
The patent uses self-service principles where containers automatically organize themselves into the optimal staggered pattern with alternating columns of 3 and 4 containers. The containers' own geometry and contact forces drive them into the correct positions, achieving maximum compactness and rigidity without requiring complex control systems to manage the alternating column distribution.
