Solution Overview

Problem

Existing roof covering methods with tile-like sheets face challenges in efficient and flexible assembly, requiring extra fittings and limiting directional installation, while also not allowing for easy replacement of damaged parts and adequate water drainage and air circulation.

Innovation Solution

A method of mounting roof covering elements where each sheet is stabilized by screws through specific holes and cramps, allowing for flexible assembly direction and easy replacement, with a semicircular bend of the lower edge placed in a semicircular deflection of the sheet to be covered, enabling free water drainage and air circulation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional roof covering methods are used with tile-like sheets, then assembly requires extra fittings and limits directional installation, but the patent enables flexible assembly in any direction with no extra fittings needed

Engineering Contradiction:
Improveassembly direction flexibilityVSAvoidnumber of fittings required
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple functions into the sheet edges themselves: the overlapping edges serve as both the structural connection element and the fastening element, eliminating the need for separate fittings. The sheets are designed with integrated features where the right edge of one sheet directly engages with the left edge of the adjacent sheet through standardized hole patterns and overlapping geometry.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The sheet design provides multi-functionality: the same overlapping edge structure enables assembly in any direction (horizontal, vertical, diagonal), serves as both structural support and fastening mechanism, and allows for easy disassembly and replacement. The standardized hole pattern at each corner serves multiple purposes for different assembly configurations.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of repair

If traditional roof covering methods are used, then damaged parts cannot be easily replaced, but the patent enables easy replacement of damaged sheets

Engineering Contradiction:
Improvedamaged sheet replacementVSAvoidassembly procedure complexity
Core Design Contradiction:
Ease of repairVSDevice complexity

Solution Approach 1:

The roof covering is segmented into individual replaceable sheets with standardized connection points. Each sheet can be independently removed and replaced by loosening the fastening screws at its four corners, without requiring removal of adjacent sheets. The modular design with standardized overlapping edges and hole patterns enables easy segmentation and reassembly.

Inventive Principle:
Principle #1Segmentation

3Object-affected harmful factors

If sheets are tightly overlapped, then water drainage and air circulation are restricted, but the patent enables free water drainage and air circulation

Engineering Contradiction:
Improvewater drainage and air circulationVSAvoidroof covering stability
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The sheet design implements local quality differentiation: the overlapping edges provide tight coverage for structural stability, while the interior regions maintain spacing for drainage and circulation. The wave-like embossing and semicircular deflections create localized channels for water and air flow without compromising the overall overlapping structure's integrity.

Inventive Principle:
Principle #3Local quality

AI summary

Method of a roof covering with roof covering elements (tile-like sheets), in which the lower transversal step has got fixing sunken embossing well-fitting to the bend of the upper transversal step of an adjacent roof covering element placed over the former one, performed according to fixed procedure, preferably with use of prefabricated assembling embossments and holes, exploiting embossments at a corner of the roof covering element and an element fixed to a roof with mounting device at one end and its the other end clamps an edge of the roof covering element to the roofing characterised in that the left edge (1.1) of an initial sheet (1) stabilized by fastening with at least one screw to a roof batten (3) is covered by the right edge (4.1) of the second sheet (4). The sheets are mounted by a screw placed through the right lower assembling hole (4.2) of the second sheet (4) and the left lower assembling hole (1.2) of the initial sheet (1). Then the second sheet (4) is stabilized by mounting at least of one screw to a roof batten (3). The lower edge (5.1) of the third sheet (5) is put onto the upper edge (1.3) the initial sheet (1). These sheets are mounted by a screw placed through the right lower assembling hole (5.2) of the third sheet (5) and the right upper assembling hole (1.4) of the initial sheet (1) and at the same time, the left lower assembling hole (5.3) of the third sheet (5) appears over the right upper assembling hole (4.3) of the second sheet (4). Then the right edge (6.1) of the fourth sheet (6) is put onto the left edge (5.4) of the third sheet (5), whilst the lower edge (6.2) of the fourth sheet (6) is placed onto the upper edge (4.4) of the second sheet (4). The fourth (6) and the second (4) sheets are mounted by a screw applied through, preferably, the middle lower assembling hole (6.6) of the fourth sheet (6) and through the middle upper assembling hole (4.8) of the second sheet (4). The junction comprised of corners of four sheets is mounted with a screw applied through the right lower assembling hole (6.4) of the fourth sheet (6), the left lower assembling hole (5.3). of the third sheet (5), the right upper assembling hole (4.3) of the second sheet (4) and through the left upper assembling hole (1.5) of the initial sheet (1). Every time, the bend (5.7) or (6.7) - preferably straight - of the lower edge end (5.1) or (6.2) of a sheet put onto a covered one, is placed in a semicircular deflection (1.6) or (4.9) of the sheet to be covered.
