Solution Overview
Problem
Conveyor belt scrapers face challenges with complex and costly assembly, uneven wear due to varying material properties of torsion spring elements, and limited speed range due to elastic stripping elements, leading to increased production costs and reduced service life.
Innovation Solution
A compact, one-piece segment body with a quick-release fastener and adjustable spring elements allows for flexible attachment and force amplification or reduction, enabling easy assembly and extended service life while reducing production costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If elastic stripping elements are mounted on the carrier at several points or with complex construction, then contact pressure is achieved, but production costs increase
Solution Approach 1:
The scraper system is divided into modular segments where each segment body contains its own spring element and scraper element. This segmentation allows each unit to be assembled independently and mounted on the carrier at multiple points without requiring complex interconnections, thereby achieving contact pressure while reducing assembly complexity
Solution Approach 2:
The spring element and scraper element are combined within a single segment body structure. The spring element is integrated into the segment body and directly supports the scraper element, merging the force generation and application functions into one compact unit. This eliminates the need for separate mounting mechanisms and reduces overall assembly complexity
2Force
If steel spring elements are used, then contact pressure is generated, but natural frequency is reached quickly limiting speed range
Solution Approach 1:
The spring element parameters (material composition, wire diameter, coil diameter, number of coils) are specifically optimized to adjust the natural frequency away from operational ranges. By changing these parameters, the spring element maintains contact pressure functionality while avoiding resonance at typical conveyor belt speeds, thus expanding the usable speed range
3Force
If torsion spring elements are used, then contact pressure is available, but material property variations cause uneven wear
Solution Approach 1:
All spring elements across different segment bodies are manufactured with identical material properties and geometric parameters. This homogeneity ensures that each spring element generates the same contact pressure force, leading to uniform wear distribution across all scraper elements and preventing premature failure due to uneven wear patterns
4Force
If multiple components are used in wiper structure, then contact pressure mechanism is achieved, but assembly becomes complicated and production expensive
Solution Approach 1:
The spring element, scraper element, and mounting features are merged into a single integrated segment body. This consolidation eliminates the need for multiple separate components and complex assembly operations, significantly reducing production costs while maintaining the contact pressure function
Solution Approach 2:
The segment body is designed as a universal module that can be mounted at any position on the carrier and performs the same cleaning function. This multi-position universality reduces the number of unique parts needed and simplifies both manufacturing and assembly processes, lowering production costs
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 solution facilitates quick and cost-effective assembly, maintains consistent contact pressure, and extends the service life of conveyor belt scrapers by allowing for flexible attachment and force adjustment, reducing production costs and assembly complexity.
Implementation Method 1
The introduced pretensioning force can be stored in the spring element and can be reversibly introduced into the scraper and thus in the direction of the conveyor belt as a contact pressure during operation
Implementation Method 2
a conveyor belt scraper, in which elastic deformation of the segment body under a force introduced by means of the spring element can take place in a joint-like manner in the area of the support area
