Solution Overview

Problem

Existing joining devices for conveyor belts require significant force to insert the second end between the wings, making the assembly process difficult due to the spacer's central positioning, which increases manufacturing costs and complexity due to the need for multiple molds to accommodate various belt thicknesses.

Innovation Solution

A joining device with a removable spacer offset from the junction plane, allowing easier insertion of the conveyor belt end by promoting wing spacing through elastic deformation, and a dual-function fixing device that centers and secures the spacer, improving resistance and simplifying the assembly process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the spacer is positioned at the center of the joining device, then the structure is symmetric and stable, but significant force is required to insert the conveyor belt end between the wings, making assembly difficult

Engineering Contradiction:
Improvestructural stabilityVSAvoidease of insertion
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The spacer is positioned asymmetrically relative to the joining plane, specifically offset towards one of the wing pairs. This asymmetric positioning creates unequal spacing between the spacer and the two pairs of wings, allowing one pair of wings to be closer and easier to open for belt insertion, while the other pair remains more constrained for structural stability during the joining process.

Inventive Principle:
Principle #4Asymmetry

2Adaptability or versatility

If multiple molds are used to accommodate various belt thicknesses, then the joining device can handle different conveyor belt thicknesses, but manufacturing costs and complexity increase

Engineering Contradiction:
Improveadaptability to belt thicknessVSAvoidmanufacturing cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The joining device incorporates movable or adjustable components that allow the structure to adapt dynamically to different belt thicknesses. The spacer positioning and wing configuration enable the device to accommodate a range of thicknesses through mechanical adjustment rather than requiring separate molded components for each thickness variant.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The joining device is designed as a universal tool that can handle multiple conveyor belt thicknesses using the same mold and component set. The asymmetric spacer positioning and adjustable wing mechanisms provide multi-functionality, allowing a single device design to serve multiple thickness requirements without increasing manufacturing complexity.

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

3Ease of operation

If the spacer is offset from the joining plane, then the space between the second pair of wings is freed for easier belt insertion, but the structural symmetry is reduced

Engineering Contradiction:
Improveease of insertionVSAvoidstructural symmetry
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The spacer is deliberately positioned asymmetrically relative to the joining plane, creating unequal spacing between the spacer and the two pairs of wings. This asymmetric configuration frees up space between one pair of wings (the second pair) to facilitate easier conveyor belt end insertion, while maintaining sufficient structural stability through the overall design and constraint mechanisms.

Inventive Principle:
Principle #4Asymmetry
