Solution Overview

Problem

Existing roller assemblies for conveyor systems have numerous individual parts, leading to mechanical weak points and wear surfaces, which can compromise their durability and performance.

Innovation Solution

A roller arrangement where the roller axle body is clamped in the insertion channels of the roller suspension using elastic damping elements, eliminating the need for additional clips and allowing the damping elements to serve both damping and attachment functions, with positive-locking connections for stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple individual parts are used in the roller assembly (roller, roller suspension, damping element, clip), then the damping function can be achieved, but the number of mechanical weak points and wear surfaces increases

Engineering Contradiction:
ImprovedurabilityVSAvoidnumber of parts
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the attachment function (clip) and damping function (damping element) into a single integrated damping element that performs both functions simultaneously. The damping element is designed with a clamping structure that directly secures the roller axle body to the roller suspension while providing vibration damping, thereby reducing the total number of parts and eliminating the mechanical weak points associated with multiple separate components

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The damping element is designed to serve multiple functions: it provides vibration damping, attaches the roller to the roller suspension, and secures the roller axle body in position. This multi-functional design eliminates the need for separate clips and reduces the number of wear surfaces, thereby improving reliability while reducing device complexity

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If multiple individual parts are used in the roller assembly, then the damping function can be achieved, but many wear surfaces are created

Engineering Contradiction:
ImprovedurabilityVSAvoidnumber of wear surfaces
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the attachment and damping functions into a single component, thereby reducing the number of contact interfaces and wear surfaces. The integrated damping element has fewer mating surfaces compared to separate clips and damping elements, reducing the overall number of wear points in the assembly

Inventive Principle:
Principle #5Merging (Combining)

3Device complexity

If elastic damping elements are used to clamp the roller axle body, then the number of parts is reduced, but the fastening mechanism becomes more complex

Engineering Contradiction:
Improvenumber of partsVSAvoidmanufacturing complexity
Core Design Contradiction:
Device complexityVSEase of manufacture

Solution Approach 1:

The damping element utilizes elastic deformation as a key parameter to achieve both attachment and damping functions. By designing the damping element with specific elastic properties and geometric features (such as curved surfaces and resilient sections), the component can dynamically adapt to assembly tolerances and provide secure fastening without requiring complex manufacturing processes or additional fastening mechanisms

Inventive Principle:
Principle #35Parameter changes
