Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional guard apparatuses for conveyor systems experience friction-related issues, leading to reduced life and reliability, loosening, and unintentional breakage, while also increasing manufacturing complexity and cost due to complex profiles.
Innovation Solution
A guard assembly with a top cover and holder, featuring friction-reducing elements like recessed serrations and tapered grooves, is detachably secured between conveyor rollers to reduce friction and prevent unauthorized access, debris accumulation, and finger injuries, using lightweight polymer materials and simplified manufacturing methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional guard apparatuses are used to secure conveyor gaps, then safety and protection functions are provided, but friction-related issues cause reduced life and reliability, loosening, and unintentional breakage
Solution Approach 1:
The patent introduces an intermediary friction-reducing element (such as a friction-reducing coating or layer) between the guard apparatus and the conveyor roller surface. This intermediary layer reduces direct friction and wear between the guard apparatus and the roller, thereby extending the life and reliability of the guard assembly while maintaining its protective function.
Solution Approach 2:
The patent modifies the surface properties of the guard apparatus by applying friction-reducing coatings or treatments that change the coefficient of friction between the guard and the roller. This parameter change reduces the harmful friction forces that cause loosening and breakage, thereby improving reliability without compromising the guard's structural integrity or protective capability.
2Reliability
If complex profiles are used in conventional guard apparatuses, then protection and safety functions are enhanced, but manufacturing complexity and cost increase
Solution Approach 1:
The patent divides the guard apparatus into modular segments or components that can be manufactured separately using simpler processes and then assembled together. This segmentation allows each component to be produced with less complex manufacturing operations while the assembled structure maintains the necessary protection and safety functions.
Solution Approach 2:
The patent combines multiple functions into a single integrated guard assembly structure that achieves the required protection level without requiring complex individual components. By merging the protective barrier function, the mounting structure, and the friction-reducing features into a unified design, the overall manufacturing complexity is reduced while maintaining effective protection.
