Solution Overview

Problem

The existing methods for fixing profile bars to glass panes in glazing systems are time-consuming and laborious, particularly due to the need for precise alignment and machining of holes in the glass pane, which slows down manufacturing and installation processes.

Innovation Solution

The profile bar is attached to the glass pane using a design with elongated slots and elastic locking members that press the glass pane against the profile bar, eliminating the need for screws and allowing for faster installation and secure fixing, with the machining of locking shapes enabling alignment without stopping the glass pane.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If profile bars are fixed to glass panes using traditional methods (screws, compression, glue), then the fixing is secure, but the installation process becomes time-consuming and laborious

Engineering Contradiction:
Improvefixing securityVSAvoidinstallation speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The profile bar incorporates an elastic element that can dynamically deform during installation to allow the glass pane to be inserted, then returns to its original shape to lock the glass pane securely in place. This dynamic behavior enables both easy installation and secure fixing without requiring multiple fastening operations.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The elastic locking mechanism is designed to automatically engage and lock the glass pane in place once inserted into the profile bar. The elastic element self-activates through the insertion motion itself, eliminating the need for separate screwing or clamping operations and significantly reducing installation time while maintaining secure fixing.

Inventive Principle:
Principle #25Self-service

2Reliability

If holes are machined in glass panes for screw fixation, then the profile bar can be securely attached, but the manufacturing process must stop and align with precision in two perpendicular directions

Engineering Contradiction:
Improveattachment securityVSAvoidprocessing time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The invention extracts the need for hole machining and screw fixation from the attachment process. Instead of creating holes in the glass pane, the profile bar uses an elastic locking mechanism that engages with the glass pane edge directly, eliminating the time-consuming hole machining and precision alignment steps while maintaining secure attachment.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The traditional mechanical screw-fixation system is replaced with an elastic deformation-based locking mechanism. The elastic element uses its inherent elasticity to create a secure mechanical interlock with the glass pane edge, substituting the complex hole-machining-and-screwing process with a simple insertion motion that triggers automatic locking.

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

3Ease of operation

If the profile bar uses compression fixing with slots, then the glass pane can be held in place, but additional fixing members like screws are still required

Engineering Contradiction:
Improveinstallation simplicityVSAvoidfixing mechanism complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The invention merges the compression holding function and the locking function into a single integrated elastic mechanism. The elastic element simultaneously provides the compression force to hold the glass pane and the locking action to prevent removal, eliminating the need for separate fixing members and simplifying the overall fixing mechanism.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A panel structure for a glazing system, comprising a panel and a profile bar to be locked to the panel. The panel (22) is made of glass material, comprising a first and a second side surface (22a, 22b) which are parallel, and an end surface (22c) which is placed between said side surfaces and to which said side surfaces are limited; and the panel (22) further comprises one or more elongated grooves (25) provided in the first side surface (22a) and being substantially parallel with said end surface. The profile bar (20) has a profile form extending away in the longitudinal direction of the profile bar, comprising a slot (21) with a long opening (18) for the installation of the panel, and a side wall (21 b) which limits said slot and is placed on the first side surface (22a) of the panel placed in the slot. The profile bar (20) further comprises at least one locking formed part (23, 24) provided in said side wall and placed in said groove (25).
