Solution Overview

Problem

The existing solutions for creating sliding hatches in ornamental pond shelters require costly adaptations and additional stiffening, increasing the number of profiles and crosspieces, which complicates installation and increases costs.

Innovation Solution

The edges of alveolar polycarbonate panels are preformed with a thinning to accommodate a retaining profile that allows sliding, reducing the need for crosspieces and simplifying the assembly process by integrating the sliding connection directly into the panel and frame profiles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If sliding hatches are implemented in ornamental pond shelters using conventional methods, then access and ventilation functions are improved, but the number of profiles and crosspieces increases, manufacturing cost increases, and device complexity increases

Engineering Contradiction:
Improveaccess and ventilationVSAvoidnumber of profiles and crosspieces
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines the sliding mechanism and retention function into a single integrated profile system. The U-shaped profile integrates the retaining wall, sliding groove, and reinforcement functions into one component, eliminating the need for separate crosspieces and multiple profiles, thus reducing device complexity while maintaining access and ventilation capabilities

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The beam profile is designed to serve multiple functions simultaneously: it provides structural support, contains grooves for panel retention, enables sliding movement, and reinforces the hatch opening. This multi-functional design eliminates the need for dedicated stiffening profiles and crosspieces, reducing the overall number of components

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

AI summary

The cover has a set of roof modules that is arranged in a movable or non-movable manner. The set of roof modules is formed of a supporting frame formed from a set of panels (400). Two beams are braced by a set of cross-pieces. A pair of frame sections (310) is arranged to receive an edge of the cover, and is preformed with a profile retainer so as to allow sliding of a pair of profiles. The frame sections are placed between the beams to accommodate the panels.
