Solution Overview

Problem

The existing junction devices for conveyor belts require multiple molds for various thicknesses, leading to high manufacturing, storage, and distribution costs, while maintaining the quality and strength of the fastening means.

Innovation Solution

A junction plate design with first and second interfaces arranged in a repeated pattern, allowing the same type of plate to function as both upper and lower plates, manufactured from a continuous belt, reducing the need for multiple molds and simplifying installation and maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple molds are used for various thicknesses of conveyor belts, then the junction device can accommodate different belt specifications, but the manufacturing, storage, and distribution costs increase

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

Solution Approach 1:

The junction plate is designed with a universal structure that can serve multiple functions for different belt thicknesses. The plate includes a body with a through hole and a recess that can accommodate various belt thicknesses, eliminating the need for multiple specialized molds. This multi-functional design allows a single junction plate type to replace several thickness-specific variants, directly reducing manufacturing complexity and cost while maintaining adaptability.

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

2Adaptability or versatility

If multiple molds are used for various thicknesses, then different belt specifications are covered, but the storage and distribution complexity increases

Engineering Contradiction:
Improvecoverage of belt specificationsVSAvoidnumber of mold types
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The junction plate incorporates a universal design with a through hole and recess structure that can accommodate multiple belt thicknesses simultaneously. This single mold design replaces the previous need for multiple thickness-specific molds, simplifying the manufacturing system while maintaining the ability to serve different conveyor belt specifications.

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

3Strength

If traditional junction devices are used with separate upper and lower plates, then the fastening strength is maintained, but the manufacturing and maintenance complexity increases

Engineering Contradiction:
Improvefastening strengthVSAvoidnumber of plate components
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The invention merges the previously separate upper and lower junction plates into a single integrated junction plate structure. This unified plate includes a body with a through hole for fastening means and a recess for belt end engagement, combining the functions of multiple components. This reduction in component count simplifies manufacturing and assembly while maintaining the necessary fastening strength through the integrated structural design.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A junction plate for a junction device of conveyor belt intended to connect two ends of at least one conveyor belt. The junction device is of a type having at least two junction plates fastened together with the ends of the conveyor belt by fasteners each including a head and an anchoring section. The junction plate includes first interfaces to cooperate with the heads of the fasteners and second interfaces to cooperate with the anchoring sections of the fasteners. The second interfaces are distinct from the first interfaces and include inserts incorporated at least in part in the junction plate. The first and second interfaces are arranged so as to form a succession of patterns which are repeated, and each pattern has as many first interfaces as second interfaces.
