Solution Overview

Problem

Existing positioning systems for flooring or walls require significant time for operation due to the need for screwing and unscrewing, which slows down the alignment and positioning process, leading to inefficiencies in achieving a regular surface with uniform joints.

Innovation Solution

A positioning system that includes a spacer element with a threaded pin and a fixing device with actuation elements allowing for easy connection and disconnection without the need for unscrewing, enabling faster alignment and positioning of adjacent covering elements with predetermined joint dimensions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If a threaded pin and handle system is used for positioning covering elements, then alignment precision is improved, but operation time increases due to screwing and unscrewing

Engineering Contradiction:
Improvealignment precisionVSAvoidoperation time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The positioning system is divided into separable components: a reusable fixing device with flange and a disposable spacer element with threaded pin. This allows the time-consuming threaded connection to be performed only once per spacer element, while the fixing device can be rapidly reused across multiple positioning operations, significantly reducing cumulative operation time while maintaining alignment precision through the consistent flange reference surface.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The spacer element containing the threaded pin is designed as a disposable component that is broken and discarded after use. This eliminates the need to unscrew and store threaded pins between uses, allowing operators to quickly discard used spacers and install new ones without time-consuming disassembly operations, thereby reducing operation time while the reusable fixing device maintains precision alignment.

2Manufacturing precision

If a spacer element with breaking line is used, then joint dimension control is improved, but device complexity increases

Engineering Contradiction:
Improvejoint dimension controlVSAvoiddevice complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The spacer element is pre-designed with a weakened zone or breaking line at the precise location where the joint dimension needs to be controlled. This preliminary preparation allows the spacer to be easily broken at the correct position after use, ensuring accurate joint dimensions without requiring complex measurement or adjustment mechanisms during the positioning operation itself.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The spacer element with integrated breaking line is designed as a disposable component that combines joint dimension control functionality with a simple breakage mechanism. This approach achieves precise joint dimension control through the pre-defined breaking line while avoiding complex adjustable mechanisms, as the entire spacer including the control feature is discarded after single use.
