Solution Overview

Problem

Existing fastening devices for connecting belt segments to machines face challenges in achieving maximum force transmission while minimizing installation space requirements, often resulting in high surface pressure and increased installation complexity.

Innovation Solution

A fastening device with a connecting element and receiving device, where the connecting element has a shoulder and clamping unit that clamps onto steel cables, and the receiving device has multiple shells for complete positive reception, allowing even force distribution and compact design.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stress or pressure

If the connecting element is enlarged to reduce surface pressure, then surface pressure distribution improves, but installation space requirements increase

Engineering Contradiction:
Improvesurface pressureVSAvoidinstallation space
Core Design Contradiction:
Stress or pressureVSVolume of moving object

Solution Approach 1:

The connecting element is divided into multiple functional parts: a clamping unit with cable-receiving openings and a shoulder portion. This segmentation allows the force transmission function to be separated from the cable anchoring function, enabling compact design while maintaining even surface pressure distribution through the shoulder's geometry.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The shoulder portion is designed with specific geometric characteristics that create favorable stress distribution at the interface with the receiving device. The local geometry of the shoulder provides even surface pressure without requiring overall enlargement of the connecting element, thus resolving the contradiction between pressure distribution and installation space.

Inventive Principle:
Principle #3Local quality

2Force

If traditional clamp connections are used in tight spaces, then force transmission is achieved, but installation complexity and risk of improper execution increase

Engineering Contradiction:
Improveforce transmissionVSAvoidinstallation complexity
Core Design Contradiction:
ForceVSEase of operation

Solution Approach 1:

The clamping unit is designed to automatically secure the cables through its structure. The cables are received in openings and secured without requiring complex adjustment or tightening operations, making the installation process simpler and more reliable even in tight spaces.

Inventive Principle:
Principle #25Self-service

3Power

If force is transmitted over a small area, then installation space is minimized, but locally high load results in reduced power transmission capacity

Engineering Contradiction:
Improvepower transmission capacityVSAvoidinterface area
Core Design Contradiction:
PowerVSArea of stationary object

Solution Approach 1:

The shoulder portion extends in a direction perpendicular to the main force transmission axis, distributing the load over a larger three-dimensional volume rather than concentrating it on a small flat surface. This dimensional extension increases the effective load-bearing area without significantly increasing the footprint in the primary installation plane.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
