Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional metal rollers in conveyor devices generate noise and risk damaging objects, especially when used in inclined configurations, due to hard surfaces and collisions.
Innovation Solution
Conveying rollers with elastically deformable blade-shaped pieces around a core member, which absorb collision impacts and reduce noise, allowing for dense arrangement and varied lengths with shared components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a metal conveying roller with a hard surface is used, then the conveying roller has high strength and durability, but the object may be damaged and sound is generated when an object collides with the conveying roller
Solution Approach 1:
The conveying roller uses a composite structure combining a metal core member with elastic blade-shaped pieces made of rubber or plastic materials. This composite design provides both the strength needed for conveying and the elasticity to absorb collision impacts, preventing object damage and reducing noise generation.
Solution Approach 2:
The invention changes the material parameter of the conveying roller surface from hard metal to elastic material (rubber or plastic). This parameter change allows the surface to deform elastically during collision, absorbing impact energy and preventing damage to conveyed objects while reducing noise.
2Object-affected harmful factors
If the conveying roller uses elastic blade-shaped pieces, then collision impacts are softened and noise is reduced, but the structural complexity increases
Solution Approach 1:
The conveying roller surface is segmented into multiple blade-shaped pieces arranged around the core member. Each blade is an independent elastic element that can deform individually during collision, distributing the impact across multiple points and effectively softening collisions while maintaining a relatively simple overall structure.
Solution Approach 2:
The blade-shaped pieces are designed as thin, flexible elements that can easily deform elastically. This flexible structure allows the conveying roller to absorb collision impacts effectively while keeping the individual components simple and the overall assembly not overly complex.
3Object-affected harmful factors
If the blade-shaped pieces are arranged densely around the core member, then the impact distribution is improved and object damage is reduced, but the manufacturing complexity increases
Solution Approach 1:
The conveying roller surface is divided into multiple blade-shaped segments arranged around the core member. This segmentation allows for uniform impact distribution across the surface while each segment can be manufactured independently, simplifying the overall manufacturing process compared to a monolithic structure.
Solution Approach 2:
By changing the material parameter to elastic materials like rubber or plastic, the invention enables dense arrangement of blade-shaped pieces that can deform to distribute impacts uniformly. The elastic material properties allow for flexible manufacturing processes that can accommodate dense arrangements without significantly increasing manufacturing complexity.
