Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The production of transition areas in belt conveyor systems, where the conveyor belt transitions from a trough shape to a flat surface at deflection rollers, is complicated and expensive due to the need for specialized, manually crafted triangular sheet metal parts.
Innovation Solution
A support device featuring a cast part with a tapered insertion area, a flat base, and an inclined belt support, allowing for easy mass production and integration with sheet metal parts to create smooth transitions and secure connections, using materials like cast aluminum or plastic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If triangular sheet metal parts are used in transition areas, then the conveyor belt can be brought back to a flat surface at deflection rollers, but the production becomes expensive and complicated due to special geometry requirements
Solution Approach 1:
The patent changes the manufacturing method from manual cutting and shaping of triangular sheet metal parts to injection molding of polymeric transition elements. This parameter change in the manufacturing process enables mass production while maintaining the precise geometric requirements for smooth belt transitions, thereby reducing production costs and complexity.
Solution Approach 2:
The patent uses polymeric materials (such as polyethylene or polypropylene) for the transition elements instead of traditional metal sheet metal. This material substitution allows for complex geometries to be easily formed through injection molding, eliminating the need for expensive manual metalworking while achieving the same functional result of smooth belt transitions.
2Stability of the object's composition
If specially bent metal sheets are used in transition areas, then the conveyor belt transitions smoothly from trough to flat shape, but the production becomes complicated and expensive
Solution Approach 1:
The patent changes the manufacturing approach from manual metal bending and shaping to injection molding of polymeric components. This enables complex three-dimensional transition geometries to be produced through a standardized, automated process, reducing production complexity while maintaining continuous and stable belt transitions from trough to flat shapes.
Solution Approach 2:
The patent creates reusable injection molding tools that can be used to mass-produce identical transition elements. This copying approach allows the complex geometry of the transition areas to be replicated efficiently without requiring manual craftsmanship for each component, thereby reducing overall production complexity.
3Ease of manufacture
If cast parts with tapered insertion areas are used, then mass production becomes simple and cost-effective, but integration with existing sheet metal parts requires additional steps
Solution Approach 1:
The patent divides the support device into separate modular components: the injection-molded polymeric transition element and the existing sheet metal support structure. This segmentation allows each component to be manufactured independently using optimal processes (injection molding for the transition element, conventional fabrication for the sheet metal), and then assembled together, balancing mass production capabilities with integration requirements.
