Stackable Protective Covers for Packaging Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The lack of a suitable storage solution for protective covers on packaging machines leads to clutter, potential damage, and hygiene issues, as they are often placed on the floor or insecurely positioned, disrupting operations and compromising safety and cleanliness.
Innovation Solution
Designing protective covers that are stackable with integrated stack stops, allowing them to be securely stored on the packaging machine, eliminating the need for additional holding devices and reducing space usage, while maintaining hygiene standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If protective covers are placed loosely on the machine rack, then accessibility to the machine is improved, but the protective covers become unstable and may slide down or fall off
Solution Approach 1:
The protective cover is designed with a tiltable lid that can be dynamically adjusted between a closed position (providing protection) and an open position (providing access). This dynamic structure allows the cover to adapt to different operational states, improving accessibility while maintaining stability through controlled movement rather than complete removal.
2Ease of repair
If protective covers are removed from the machine, then access for maintenance and cleaning is improved, but the covers must be placed on the floor or adjacent areas creating hygiene issues and potential damage
Solution Approach 1:
The protective covers are designed to nest within each other when not in use, with smaller covers fitting inside larger ones. This nesting arrangement provides a compact, organized storage solution that keeps covers elevated and secure on the machine rack, eliminating the need to place them on the floor and preventing both hygiene contamination and physical damage.
Solution Approach 2:
The protective cover structure includes integrated features such as handles, lifting mechanisms, and self-aligning components that enable operators to easily remove, store, and reinstall covers without requiring additional tools or assistance. This self-service design simplifies maintenance access while ensuring covers are properly positioned and secured during storage.
3Area of stationary object
If protective covers are stacked without proper support structures, then space utilization is improved, but additional mechanical holding devices are required increasing device complexity
Solution Approach 1:
The protective covers are designed with integrated stacking features built into their structure, such as recesses, protrusions, or interlocking edges that allow them to stack and support each other without requiring separate mechanical holding devices. This merging of storage functionality into the covers themselves simplifies the overall system while maximizing space utilization on the machine rack.

AI summary
A packaging machine comprising a sealing station with a sealing tool, a side frame and at least a first as well as a second upper protective cover respectively for placement onto a top side of the side frame during the manufacturing operations, wherein each of the two protective covers form a body with a lid, multiple side walls as well as a bottom. In one embodiment, the two protective covers can be stacked on one another, wherein at least one of the two protective covers forms at least one stack stop on the lid to which an edge of the floor of the other protective cover can be coupled in a removable way if the two protective covers are stacked on top of one another. In one embodiment, the packaging machine may be a deep-drawing packaging machine or a tray-sealing machine.
