Solution Overview

Problem

Existing tile levelling devices require significant manual effort and time for screwing and unscrewing operations, making the levelling process inefficient.

Innovation Solution

The device incorporates a pressure body with magnetic attraction to an external rotating member, allowing for quick coupling and uncoupling with the elongated body or rod, facilitated by a screwing tool that can rotate the pressure body in both directions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual screwing and unscrewing of the pressure member onto the elongated body is used, then secure mechanical connection is achieved, but significant time is required for coupling and uncoupling operations

Engineering Contradiction:

Improvemechanical connectionVSAvoidcoupling and uncoupling time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent replaces the traditional threaded mechanical screwing system with a magnetic coupling system. The pressure member and elongated body are equipped with magnetic elements that enable automatic mechanical connection through magnetic attraction, eliminating the need for manual screwing and unscrewing operations while maintaining secure connection reliability

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces magnetic fields as an intermediary force between the pressure member and elongated body. This magnetic intermediary enables automatic coupling and uncoupling operations, replacing the direct mechanical interaction of threading and eliminating time-consuming manual operations

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If frequent coupling and uncoupling of the pressure member is performed, then levelling operations can be completed, but the lengthy screwing and unscrewing process becomes the bottleneck

Engineering Contradiction:

Improvelevelling operation speedVSAvoidscrewing and unscrewing time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent replaces the time-consuming threaded mechanical system with a magnetic coupling system that enables rapid attachment and detachment. This substitution eliminates the bottleneck of manual screwing and unscrewing, allowing frequent coupling and uncoupling operations to be performed quickly, thereby significantly improving overall levelling productivity

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Loss of time

If a magnetic coupling system is used instead of threading, then coupling and uncoupling time is reduced, but the device complexity increases due to additional magnetic components

Engineering Contradiction:

Improvecoupling and uncoupling timeVSAvoiddevice structure

Core Design Contradiction:

Loss of timeVSDevice complexity

Solution Approach 1:

The patent merges the magnetic coupling functionality directly into the existing pressure member and elongated body structures. The magnetic elements are integrated into the design of these components rather than being added as separate external systems, thereby reducing overall device complexity while still achieving rapid coupling and uncoupling operations

Inventive Principle:

Principle #5Merging (Combining)
