Solution Overview

Problem

Conveyor belts often require external support structures to prevent sagging and collapse under load, which increases complexity and reduces modularity, and existing linkage assemblies do not efficiently transition between self-supporting and non-self-supporting positions for navigating linear and curved paths.

Innovation Solution

A conveyor belt system featuring a self-supporting linkage assembly with interlocking links and a biasing member that allows links to move between engaged and disengaged positions, enabling the belt to support itself in linear segments while disengaging for curved segments, reducing the need for external support and enhancing modularity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If external support structures are used to prevent sagging and collapse, then the conveyor belt can support itself, but the device complexity increases and modularity decreases

Engineering Contradiction:
Improveself-support capabilityVSAvoidsupport structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The conveyor belt system performs self-support through its linkage assembly that automatically engages and disengages based on the path geometry. The biasing member causes the linkage to engage in linear segments to provide self-support, and disengage in curved segments to allow navigation, eliminating the need for external support structures.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The linkage assembly transitions dynamically between engaged and disengaged states based on the operational requirements. In linear segments, the linkage engages to provide structural support, while in curved segments, it disengages to allow the belt to follow the curve, creating a adaptive support system.

Inventive Principle:
Principle #15Dynamics

2Reliability

If the linkage assembly is engaged to provide self-support, then the belt can support itself in linear segments, but it cannot navigate curved paths

Engineering Contradiction:
Improveself-support capabilityVSAvoidpath navigation capability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The linkage assembly dynamically transitions between engaged and disengaged states based on the path geometry. In linear segments, the linkage engages to provide self-support, while in curved segments, it disengages to allow the belt to follow the curve, creating an adaptive support system.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The conveyor belt path is segmented into linear segments requiring self-support and curved segments requiring flexibility. The linkage assembly responds to each segment type appropriately, engaging for linear portions and disengaging for curved portions, allowing the system to handle both path types effectively.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If the linkage assembly is disengaged to navigate curved paths, then the belt can follow curved trajectories, but it cannot support itself in linear segments

Engineering Contradiction:
Improvepath navigation capabilityVSAvoidself-support capability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The linkage assembly dynamically transitions between engaged and disengaged states based on the path geometry. In linear segments, the linkage engages to provide self-support, while in curved segments, it disengages to allow the belt to follow the curve, creating an adaptive support system.

Inventive Principle:
Principle #15Dynamics

4Shape

If a traditional support structure is used, then the conveyor belt can maintain its shape, but the assembly complexity increases

Engineering Contradiction:
Improvebelt assembly shape maintenanceVSAvoidsupport structure complexity
Core Design Contradiction:

Solution Approach 1:

The conveyor belt system performs self-support through its linkage assembly that automatically engages and disengages based on the path geometry. The biasing member causes the linkage to engage in linear segments to provide self-support, and disengage in curved segments to allow navigation, eliminating the need for external support structures.

AI summary

A conveyor belt (1000) includes a self-supporting linkage assembly (1142) and a plurality of transverse elements (1140) configured to travel along a longitudinal direction (1112). The transverse elements are interconnected by the linkage assembly. The conveyor belt also includes a biasing member (1300). The linkage assembly includes a first link (1164) and a second link (1158A). The first and second links are configured to move relative to each other between an engaged position and a disengaged position. The biasing member is configured to bias the first and second links toward the engaged position. The first and second links, when in the engaged position, are constrained against rotation relative to each other. The first and second links, when in the disengaged position, are configured to rotate relative to each other.
