Solution Overview

Problem

Existing methods for attaching or laying stone or slab-shaped facade elements and floor coverings require complex calculations and measurements to achieve uniform joint patterns, making the process labor-intensive and prone to errors, as they cannot effectively account for construction tolerances.

Innovation Solution

A device with at least two placeholder elements connected via an elastic element allows for adjustable joint widths, enabling easy division of routes into equal sections by stretching the elastic element to achieve uniform distances, which can be fixed temporarily to ensure accurate placement and distribution of stone or slab formats.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If complex calculations and measurements are performed to achieve uniform joint patterns, then manufacturing precision is improved, but device complexity and loss of time increase

Engineering Contradiction:
Improveuniform joint patternVSAvoidmeasurement and calculation process
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent changes the parameter of joint width dynamically by using an elastic element that can be stretched to compensate for construction tolerances. This allows the joint width to be adjusted as a variable parameter rather than a fixed value, enabling uniform joint patterns without complex calculations

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The device performs self-adjustment through the elastic element's inherent properties. When stretched between two points, the elastic element automatically distributes the distance into equal sections, eliminating the need for external calculations or measurements by the user

Inventive Principle:
Principle #25Self-service

2Ease of operation

If fixed joint widths are specified, then ease of operation is improved, but manufacturing precision deteriorates due to inability to account for construction tolerances

Engineering Contradiction:
Improvejoint width specificationVSAvoidjoint pattern uniformity
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The patent transforms the static, fixed joint width specification into a dynamic system where the elastic element can stretch and adapt. The joint width becomes a dynamic parameter that automatically adjusts to accommodate construction tolerances while maintaining uniform distribution, resolving the contradiction between ease of operation and precision

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If manual measurements and calculations are performed, then adaptability to different construction scenarios is improved, but productivity decreases due to labor-intensive process

Engineering Contradiction:
Improveaccommodation of construction tolerancesVSAvoidplacement speed
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The device performs the adaptive adjustment automatically through the elastic element's physical properties. When stretched, it self-calculates and self-distributes the distance into equal sections, providing adaptability to different construction scenarios without requiring manual intervention, thereby increasing productivity

Inventive Principle:
Principle #25Self-service

AI summary

The invention relates to a method for dividing a path into equal sections, in particular for determining layer heights and/or joint widths when installing stone- or slab-shaped facade elements or when laying stone- or slab-shaped floor coverings. The method uses a device comprising at least two placeholder elements (1) connected via at least one elastic element (2).The method comprises the following steps: - placing the device against a surface, whereby a first end of the device and/or an end of a placeholder element (1) arranged in this end region is brought into contact with a starting point of a section to be divided, - aligning the device parallel to the section to be divided, - fixing the first end of the device and/or the placeholder element (1) arranged in this end region to the surface, for example by simply pressing it down, - pulling on the opposite end of the device parallel to the section to be divided, whereby the other end of the device and/or an end of a placeholder element (1) preferably arranged in this end region is brought into contact with an endpoint of the section.
