Modular Scraper Segments for Conveyor Belt Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scraper devices for conveyor belts require significant effort to assemble and replace individual scraper segments, as they must be dismantled and reassembled to attach or remove segments, especially when converting between standard and turning scraper configurations.
Innovation Solution
A scraper device with detachable scraper segments connected via an elastomer area to a support element, allowing for individual segment attachment and removal without dismantling the entire device, and featuring a wedge-shaped design to reduce contamination and enable different deformation behaviors for optimal cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If scraper segments are designed to enclose the support element over its entire circumference, then the scraper segments are securely fixed to the support element, but the assembly and replacement of individual scraper segments requires significant effort and dismantling of the entire device
Solution Approach 1:
The scraper device is divided into multiple detachable scraper segments that can be independently attached and removed from the support element. Each scraper segment is a separate module that connects to the support element through a simplified interface, allowing individual replacement without dismantling the entire device.
Solution Approach 2:
The connection mechanism is extracted and simplified to allow easy attachment and detachment. The scraper segments are designed with connection elements that can be quickly secured to and removed from the support element, eliminating the need for complex dismantling procedures.
2Adaptability or versatility
If the scraper device is designed as a turning scraper with multiple scraper segments, then it can clean conveyor belts in both conveying directions, but the complexity of assembly and configuration increases
Solution Approach 1:
The turning scraper is constructed from multiple identical or similar scraper segment modules that can be attached to the support element at different positions and orientations. This modular approach allows the device to be configured for bidirectional cleaning without requiring a completely different design.
Solution Approach 2:
The scraper segments are designed with universal connection features that allow them to be used in multiple configurations. The same basic scraper segment can be attached in different orientations and positions to achieve cleaning functionality for both conveying directions, reducing overall device complexity.
3Strength
If retaining arms are used to secure scraper segments to the support element, then the scraper segments are firmly held in place, but the assembly process requires additional steps and time
Solution Approach 1:
The connection elements are pre-configured on both the scraper segments and the support element to enable quick attachment. The retaining arms or connection mechanisms are designed to be pre-positioned or easily deployable, reducing the number of steps required during assembly.
Solution Approach 2:
The connection mechanism is designed to be self-securing or self-aligning, where the scraper segment automatically engages with the support element in the correct position when brought into contact, minimizing the need for manual adjustment and reducing assembly time.
Applied Scientific Principles

Function Achieved in This Case
Enables easy conversion between standard and turning scraper configurations with minimal effort, reduces contamination risk, and allows for customizable wiper properties to optimize cleaning performance in both conveying directions.
Implementation Method 1
the scraper segments have a connecting area made of an elastomer, for example rubber, polyurethane or another plastic
Implementation Method 2
which, for example with the aid of one or more springs, applies a force directed to the conveyor belt to the support element

AI summary
The device has stripping segments (2, 2 ') attached with a tubular support element i.e. cylindrical pipe (1) that is arranged transversely to a conveying direction of a conveyor belt with attached stripping blades (5), which are pressed at the conveyor belt. The stripping segments are connected with the support element via a rotationally fixed connection region that is formed of elastomer material. The stripping segments are connected to each other opposite to the support element and comprise a half-shell-shaped connector i.e. connecting plate, for connection with the support element.
