Snap-on Glide Strips for Hygienic Conveyor Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Food processing equipment requires hygienic designs that minimize contact surfaces, eliminate mechanical fasteners, and reduce microbe harborage areas, but existing conveyor systems do not adequately address these needs.
Innovation Solution
The development of a hygienic track system for spiral and straight conveying systems using snap-on glide strips and guide blocks made from elastic materials with specific cross-sectional shapes and durometers, which snap onto slots in metal rails, allowing for easy cleaning and replacement, and reducing contact surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional conveyor systems are used, then structural strength and stability are maintained, but contact surfaces increase and hygiene is compromised
Solution Approach 1:
The conveyor system is divided into separate modular components: elastic glide strips that can be removed and cleaned independently from the metal rail structure. This segmentation allows the contact surfaces to be easily detached for cleaning while maintaining the structural integrity of the rail system.
Solution Approach 2:
The glide strips are made from elastic materials with specific durometer ranges (Shore A 60-90) that allow them to be compressed during installation and then expand to provide a hygienic, smooth contact surface. The elastic property enables the surface to be minimized while maintaining functionality.
2Object-affected harmful factors
If mechanical fasteners are eliminated, then hygiene is improved, but installation and removal complexity increases
Solution Approach 1:
The fastening mechanism is extracted from the glide strip itself and transferred to the metal rail structure through integrated slots and support features. This allows the glide strips to be installed and removed without mechanical fasteners on the contact surfaces, eliminating harborage areas while maintaining ease of operation through the slot-based attachment system.
3Object-affected harmful factors
If access for inspection is provided, then hygiene is improved, but structural integrity may be compromised
Solution Approach 1:
The separation of the elastic glide strips from the metal rail structure allows inspection access to the rail components without compromising overall structural integrity. The glide strips can be removed to inspect the rail slots and support features, while the rail structure itself maintains its load-bearing capacity.
Solution Approach 2:
The elastic glide strips act as intermediaries between the metal rail structure and the conveyor belt. They can be removed for inspection while the metal rail maintains structural integrity, as the glide strips are not critical load-bearing components but rather functional interface elements.
