Solution Overview

Problem

Existing flexible covering mounting systems require specialized tools and precision manufacturing, limiting their standardization and ease of use, as well as allowing for only one-time installation and no reusability due to the need for custom dimensions and irreversible attachment methods.

Innovation Solution

A method using V-shaped or U-shaped locking clips that are separate from the base sections and covering, allowing for easy installation and removal without damaging the covering, with the clips retaining the covering under tension and enabling standardization of manufacturing and reuse by keeping excess material within the frame.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If hook-shaped attachment profile with high-frequency heat-welding is used, then the flexible covering is securely fixed to the frame, but the manufacturing complexity increases and reusability is lost

Engineering Contradiction:
Improvefixing securityVSAvoidmanufacturing complexity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent replaces the thermal welding system (high-frequency heat-welding) with a mechanical fastening system using clips and receiving housings. This substitution eliminates the need for specialized heat-welding equipment and complex manufacturing processes while maintaining secure fixation through mechanical interlocking of the hook profile with the receiving housing.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent divides the fixation system into separate modular components: the hook-shaped attachment profile on the covering, the receiving housing in the frame, and the clip fastener. This segmentation allows each component to be manufactured independently using standard processes, enabling reuse and replacement without requiring the entire assembly to be custom-manufactured through complex thermal welding.

Inventive Principle:
Principle #1Segmentation

2Manufacturing precision

If custom manufacturing with precise dimensions is required, then the covering fits precisely on the frame, but the ease of operation decreases and standardization is lost

Engineering Contradiction:
Improvedimensional precisionVSAvoidinstallation simplicity
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The patent creates a universal fixation system where the hook-shaped profile, receiving housing, and clip can be used with multiple different coverings and frame configurations. The standardized dimensions and interchangeable components allow the same fixation mechanism to work across various applications, eliminating the need for custom manufacturing while maintaining precise fit through the mechanical interlocking design.

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

Solution Approach 2:

The patent introduces the clip as an intermediary element that mediates between the covering and the frame. This intermediate fastening component absorbs the dimensional variations and tolerance differences, allowing standard-sized coverings to fit precisely on standard frames without requiring custom manufacturing, while the clip provides the precise positioning and secure connection.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Shape

If the covering is cut flush with the frame after assembly, then a clean appearance is achieved, but reusability is lost due to dimensional reduction

Engineering Contradiction:
Improveaesthetic appearanceVSAvoidreusability
Core Design Contradiction:
ShapeVSAdaptability or versatility

Solution Approach 1:

The patent implements a nesting arrangement where the covering with its hook profile is inserted into the receiving housing of the frame, and the excess covering material is contained within the receiving housing. This nesting structure allows the covering to be extended or retracted as needed, maintaining a clean appearance while preserving the full dimensions of the covering for future reuse and repositioning.

Inventive Principle:
Principle #7Nested doll (Nesting)

4Reliability

If specialized tools and professional intervention are required, then reliable fixation is achieved, but the device complexity increases

Engineering Contradiction:
Improvefixation reliabilityVSAvoidtool requirements
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent designs a self-service fixation system where the clip can be manually inserted into the receiving housing and automatically engages with the hook profile without requiring specialized tools or professional intervention. The mechanical design provides self-aligning features and automatic locking, enabling reliable fixation to be achieved by end-users through simple manual operations.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent employs simple, inexpensive clip components that can be easily replaced if needed, eliminating the need for expensive specialized installation tools. The clip serves as a disposable or easily replaceable fastening element that provides reliable fixation through its simple mechanical design, making the system accessible to non-professionals without requiring investment in specialized equipment.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

AI summary

The invention relates to a mounting frame (100) which can be attached to a ceiling (3) and comprises an assembly of basic profiles (10) comprising a housing (14) for receiving an edge of a covering (1) and a plurality of V-shaped or U-shaped locking clips (50) designed to enter the receiving housing (14) and remain therein in a locked position in which the edge of said covering (1) is clamped between the locking clip (50) and said housing (14). Each locking clip (50) is therefore interposed between an insertion tool such as a palette knife and the covering (1) and facilitates the insertion of the covering (1) into the receiving housing (14) without damaging it. The covering (1), the dimensions of which remain greater than those of said frame, can thus be completely removed and reused since it has not been damaged in any way, either while it is being fitted or while it is being held in place.
