Rotary Latch Format Part Assembly for Quick Container Changeover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container handling systems require complex and costly replacement of format parts to accommodate different container sizes, with existing solutions being inefficient and difficult to implement.
Innovation Solution
A fastening device with a rotary latch that is rotatable between a first and second latch position, utilizing a locking element that blocks or allows rotation, enabling tool-free and quick assembly and disassembly of format parts, and incorporating a pre-tensioned mechanism for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If format parts are made interchangeable to accommodate different container sizes, then adaptability is improved, but device complexity and replacement cost increase
Solution Approach 1:
The fastening device is segmented into distinct functional components: a rotary latch mechanism for securing the format part, and a locking element with pre-tensioning for reliable attachment. This segmentation allows each component to perform its specific function efficiently, simplifying the overall replacement process while maintaining adaptability across different container sizes.
Solution Approach 2:
The rotary latch provides dynamic fastening by allowing rotation between locked and unlocked positions, enabling quick tool-free replacement. The locking element incorporates pre-tensioning that dynamically adjusts to ensure secure attachment during operation while facilitating easy release when needed, thus reducing replacement complexity.
2Ease of manufacture
If existing locking mechanisms are used for format part attachment, then manufacturing cost is reduced, but ease of operation deteriorates due to tool requirements and complex procedures
Solution Approach 1:
The fastening device is designed to be self-servicing during operation. The pre-tensioned locking element automatically maintains secure attachment without requiring external tools or complex procedures. The rotary latch provides intuitive self-contained operation where the operator can directly engage or disengage the format part by simple rotation, eliminating the need for additional tools and simplifying the replacement process.
