Toolless Wear Strip Locking Mechanism for Conveyor Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing conveyor wear strip designs require tools for removal and replacement, which can complicate maintenance and increase downtime.
Innovation Solution
A wear strip design featuring frame spacers with T-shaped locks and holes with wide and narrow gaps, allowing for secure longitudinal locking and easy tool-free removal by sliding the wear strip relative to the frame, with additional features like dynamic noser assemblies for enhanced usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wear strips are secured with traditional fastening methods, then they remain stable during operation, but they require tools for removal and replacement
Solution Approach 1:
The locking mechanism is segmented into distinct functional elements: the T-shaped lock on the frame spacer and the corresponding hole with wide/narrow gaps in the wear strip. This segmentation allows the lock to engage at two different positions (wide gap for insertion, narrow gap for locking), enabling tool-free removal while maintaining operational stability.
Solution Approach 2:
The locking mechanism transitions from a static fastening system to a dynamic one where the wear strip can be easily inserted and removed by sliding. The T-shaped lock interacts with the varying gap widths to provide automatic locking during normal operation while allowing easy release when needed, creating a dynamic ease of maintenance.
2Loss of time
If wear strips are designed for easy removal, then maintenance time is reduced, but secure locking during operation may be compromised
Solution Approach 1:
The T-shaped lock and corresponding hole feature asymmetric gap widths - a wide gap for easy insertion and a narrow gap for secure locking. This asymmetry ensures that during normal operation (reliability phase), the narrow gap provides strong locking, while during maintenance (time phase), the wide gap allows tool-free removal by parallel sliding.
Solution Approach 2:
Different regions of the locking interface have different properties: the wide gap region facilitates easy insertion and removal operations, while the narrow gap region provides secure locking during operation. This local differentiation of properties resolves the contradiction between easy maintenance and reliable operation.
3Productivity
If traditional fastening methods are used, then secure attachment is achieved, but operational efficiency decreases due to tool requirements
Solution Approach 1:
The wear strip and frame spacer locking mechanism is designed to be self-servicing - the operator can remove and replace wear strips using only the hands, without requiring external tools. The T-shaped lock and gap configuration allows the wear strip itself to be manipulated for removal, significantly improving ease of maintenance and operational efficiency.

AI summary
A dynamic noser assembly used with a conveyor having pegs is provided. The dynamic noser assembly has a noser with a noser inner side, a noser outer side, a first lateral side, a second lateral side, a rear side and a front side. The dynamic noser further has a first hole with a first hole slot accessible via the noser inner side and a first hole notch, and a second hole with a second hole slot accessible via the rear side and a second hole notch. The noser is alignable with the pegs to lock the noser in place when the pegs are received within notches. The dynamic noser assembly further as a shaft removably connected to the noser, the shaft supporting at least one bearing. The noser front side has a channel formed therein for removably receiving the bearing shaft.
