Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Soil tillage rollers for machines like compactors face issues with maintaining mass while preventing undefined movement states during vibrations.
Innovation Solution
The soil tillage roller features ballast units with elastic suspension arrangements that allow movement in all spatial directions, ensuring permanent coupling and defined positioning, with multiple units arranged circumferentially to enhance stability and prevent unwanted movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If ring-shaped ballast elements are arranged in the roller interior to increase mass, then the roller's mass is improved, but undefined movement states occur during vibrations
Solution Approach 1:
The ballast elements are designed to be movable relative to the roller shell through elastic suspension, allowing them to dynamically adjust their position during vibrations. This dynamic capability enables the ballast elements to maintain stable relative positioning while accommodating vibrational movements, resolving the contradiction between increased mass and movement stability.
Solution Approach 2:
An elastic suspension arrangement acts as an intermediary between the ballast elements and the roller shell. This suspension system allows the ballast elements to move relative to the roller shell while maintaining controlled, defined movement states during vibrations, preventing undefined movement while preserving the mass increase benefit.
2Stability of the object's composition
If ballast elements are permanently coupled to the roller shell, then movement stability is improved, but vibrational decoupling is reduced
Solution Approach 1:
The elastic suspension creates a dynamic coupling system that allows ballast elements to move relative to the roller shell during vibrations. This dynamic behavior enables the system to maintain stable positioning while effectively decoupling vibrational forces, resolving the contradiction between positioning stability and vibration resistance.
3Weight of moving object
If multiple ballast units are arranged circumferentially, then mass distribution is improved, but device complexity increases
Solution Approach 1:
The ballast system is segmented into multiple independent ballast units arranged circumferentially around the roller shell. Each unit has its own elastic suspension, allowing independent movement. This segmentation enables improved mass distribution while keeping each individual suspension arrangement relatively simple, resolving the contradiction between mass distribution and device complexity.
