Solution Overview

Problem

Existing methods for connecting laminated glass panes at their end faces face challenges in ensuring weather and aging resistance, safety, and strength, while also requiring quick and easy on-site assembly.

Innovation Solution

The method involves pre-assembling T-shaped profile strips with reinforcement elements and cover strips on the glass panes in the factory, which are then connected on-site using clamping elements and screws, enhancing strength and weather resistance, and allowing for various optical effects.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If connection is performed on-site with adhesive, then flexibility in installation is improved, but weather resistance and connection strength deteriorate due to delayed hardening at low temperatures and damage from driving rain

Engineering Contradiction:
Improveinstallation flexibilityVSAvoidweather resistance
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The T-shaped profile strips are pre-assembled with seals and reinforcement elements in the factory before transportation. This preliminary preparation ensures that the connection components are ready for immediate installation on-site without exposure to adverse weather conditions during the assembly process, thereby maintaining both installation flexibility and weather resistance.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The T-shaped profile strips serve as intermediary elements between the glass panes, incorporating integrated seals and reinforcement. These profile strips protect the connection points from driving rain and provide structural strength, mediating between the glass panes while ensuring both weather resistance and connection integrity.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If factory pre-assembly of T-shaped profile strips is performed, then on-site assembly time is reduced, but manufacturing complexity increases

Engineering Contradiction:
Improveon-site assembly speedVSAvoidmanufacturing process complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The connection system is segmented into modular T-shaped profile strips that can be independently manufactured and pre-assembled in the factory. Each profile strip is a self-contained unit with integrated functions (structural support, sealing, reinforcement), allowing for simplified factory production while enabling rapid on-site assembly through simple connection operations.

Inventive Principle:
Principle #1Segmentation

3Strength

If reinforcement elements are added to increase connection strength, then safety requirements are met, but device complexity and weight increase

Engineering Contradiction:
Improveconnection strengthVSAvoidstructural complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The reinforcement elements are merged with the T-shaped profile strips to form an integrated structural unit. The profile strips incorporate reinforcement elements within their geometry, combining the structural support function with the connection function in a single component, thereby increasing connection strength without proportionally increasing overall complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The T-shaped profile strips utilize composite construction combining aluminum alloy material with integrated reinforcement elements. This composite approach provides high strength-to-weight ratio and meets safety requirements while maintaining reasonable device complexity through efficient material utilization.

Inventive Principle:
Principle #40Composite materials

AI summary

The device has a wall portion (1) provided at the connected end face with a cross-sectional approximately T-shaped profiled strip (2), whose foot (3) on a first wall side of the wall portion and whose back having a leg on the end face abuts in the connection position. The back bears two T-shaped profile strips that remain between the end faces. A clamping element (7) is provided with clamping projections connected to the end face adjacent to the legs of the T-shaped profile strips.
