Solution Overview

Problem

Existing glazing blocks often displace adhesives or fail to ensure proper adhesive distribution during the installation of glass panes, requiring precise positioning before adhesive curing, which can be challenging and inefficient.

Innovation Solution

The glazing block features spring devices made of spaced tubes or hollow cylinder sections that minimize adhesive displacement, allowing for secure glass pane positioning after adhesive introduction, with optional connecting webs for improved stability and ease of assembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional glazing blocks are inserted into the frame rebate, then glass pane positioning is achieved, but adhesive displacement or insufficient adhesive distribution occurs

Engineering Contradiction:
Improvesecure positioning of glass paneVSAvoidadhesive displacement
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

The glazing block is divided into multiple separate spring devices (tubes or shells) spaced apart from one another. These segmented spring devices create multiple cavities for adhesive reception, allowing the adhesive to be distributed in controlled portions between the spring devices rather than being displaced as a single mass, thus maintaining reliable glass positioning while preventing adhesive loss

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The spring devices act as intermediary elements between the glazing block and the adhesive. They provide a mechanical structure that holds the glass pane in position while their spaced arrangement creates cavities that accommodate the adhesive, mediating between the positioning function and the adhesive distribution function without direct displacement

Inventive Principle:
Principle #24Intermediary (Mediator)

2Manufacturing precision

If glazing blocks are inserted before adhesive curing, then glass pane positioning is maintained, but precise positioning becomes challenging and time-consuming

Engineering Contradiction:
Improvepositioning precision of glass paneVSAvoidpositioning time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The spring devices are pre-formed with specific geometries (tubes with elliptical cross-sections or hollow cylinder sections) that create predetermined cavities for adhesive placement. This preliminary structuring allows the adhesive to be applied in a standardized manner, and the glazing block can be inserted without requiring precise manual positioning, as the spring devices themselves provide the positioning function through their fixed arrangement

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The spring devices are made of elastic material that can deform under compression. When the glazing block is inserted, the spring devices compress elastically to accommodate the adhesive and glass pane, then return to their original shape, providing a self-adjusting positioning mechanism that reduces the need for precise manual positioning and speeds up the installation process

Inventive Principle:
Principle #15Dynamics

AI summary

The block (10a) has a glass side (14) and a framework side pointing to glass in a usage condition and a frame side pointing to a frame rabbet. Cavities (20a) are arranged on the framework side for receiving cement. Spring mechanisms (22a) are material sections, which are provided for limiting the cavities. Pipes run either in longitudinal or transverse axis direction of the glazing block. Bars (24) run transverse to the longitudinal axis direction of the glazing block.
