Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conveyor belt scrapers face challenges with high wear and laborious installation due to overloading and the need for specialized support structures, leading to increased manufacturing costs and reduced operational life.
Innovation Solution
A segment body with a plate-shaped mounting element and double damping mechanisms, including a hollow body and an insertion pocket for a spring element, provides resilient support and adjustable press-on force, simplifying installation and reducing wear by absorbing jerky impacts and overloads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If flexible scraping elements are mounted to multiple locations on the carrier, then the scraper can apply press-on force to the conveyor belt, but the installation becomes very laborious and requires expensive special construction
Solution Approach 1:
The scraper is divided into modular segment bodies that can be independently installed and replaced. Each segment body contains its own mounting element and damping mechanism, allowing for simplified installation without requiring complex carrier construction while maintaining effective press-on force distribution across multiple locations.
Solution Approach 2:
The invention introduces damping mechanisms with adjustable parameters (spring constants, hollow body dimensions) that allow the press-on force characteristics to be optimized without changing the fundamental mounting structure. This enables effective cleaning force while using simpler, more easily installed carrier designs.
2Reliability
If scraper elements are consistently overloaded during operation, then they can handle conveyor belt connections or damage, but this leads to twisted or yielding scraper elements that increase wear and reduce operating life
Solution Approach 1:
The invention incorporates damping mechanisms (hollow bodies and spring elements) that are pre-configured to absorb and cushion overload impacts before they reach the scraper elements. This beforehand cushioning protects the scraper elements from twisted or yielding failures during conveyor belt connections or damage events, significantly extending operating life while maintaining reliability.
3Ease of operation
If specially manufactured support strips are used, then the scraper elements can be easier to install, but the manufacturing costs increase
Solution Approach 1:
The segment body design serves multiple functions: it provides structural support, contains the damping mechanism, holds the scraper element, and facilitates installation. This multi-functionality eliminates the need for separate specially manufactured support strips, reducing manufacturing costs while maintaining ease of installation through the integrated design.
4Force
If the carrier requires a special expensive construction, then the scraper can provide adequate press-on force, but the manufacturing costs increase
Solution Approach 1:
The invention extracts the force-generation and damping functions from the carrier structure itself and places them within the segment bodies. The carrier can therefore use simpler, less expensive construction while the segment bodies contain the specialized components (springs, hollow bodies) that provide the necessary press-on force and overload protection.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The segment body achieves higher wear resistance and simplified installation, with the double damping mechanism effectively reducing material wear and extending operational life while allowing for adjustable damping strength and easy replacement of wear parts.
Implementation Method 1
an underside of the carrier section forms a hollow body together with an opposite section of the mounting element so that the carrier section is resiliently supported on the mounting element by means of the supporting area and thus forms a first damping mechanism
Implementation Method 2
the carrier section is resiliently supported on the mounting element by means of the supporting area
Implementation Method 3
an insertion pocket on the adjoining underside of the carrier section which insertion pocket is suitable to accommodate a spring element in order to form a second damping mechanism
