Solution Overview

Problem

Existing belt grinding devices require significant labor and time to couple and detach modules due to the need for multiple screw connections, making the process cumbersome and inefficient.

Innovation Solution

A belt grinding device with a coupling element featuring a bolt and clamping bolt system that allows for easy movement between a release and coupling position, enabling secure connection between modules without the need for tools, using a clamping bar and quick-action clamping screws for a simple and secure mechanical link.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If screw connections are used to connect belt grinding modules, then a secure mechanical connection is achieved, but the coupling and detaching process requires significant labor and time

Engineering Contradiction:
Improvemechanical connection strengthVSAvoidmodule coupling and detaching time
Core Design Contradiction:
StrengthVSLoss of time

Solution Approach 1:

The connection system is segmented into a coupling element with bolts on one module and a counter-element with clamping bolts and openings on the other module. This segmentation allows the connection to be made through simple insertion and clamping actions rather than requiring multiple screw connections, thereby reducing the time and labor needed for module coupling while maintaining secure mechanical connection.

Inventive Principle:
Principle #1Segmentation

2Reliability

If multiple screw connections are made to firmly connect modules, then a stable mechanical link is achieved, but the process becomes cumbersome and requires tools

Engineering Contradiction:
Improvemechanical connection stabilityVSAvoidmodule coupling ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The fastening function is extracted from the traditional screw connection system and implemented through a dedicated clamping bolt mechanism. The clamping bolt, when moved to the coupling position, secures the bolts in the openings without requiring tools, thus maintaining connection stability while greatly improving ease of operation.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The coupling element and counter-element are designed to self-secure through the clamping bolt mechanism. Once the bolts are inserted into the openings, the clamping bolt automatically secures them in place, creating a reliable connection without requiring additional tools or complex fastening procedures.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If a simple coupling mechanism is used to reduce labor, then ease of operation improves, but the mechanical connection may be less secure against twisting or shifting

Engineering Contradiction:
Improvemodule coupling easeVSAvoidmodule connection stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The connection stability is enhanced by adding a clamping dimension to the simple insertion mechanism. The clamping bolt provides a third dimension of control (clamping force) in addition to the insertion motion, creating a secure connection that resists twisting and shifting while maintaining ease of operation through the straightforward clamp-and-lock action.

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