Solution Overview

Problem

Existing systems for cutting and crushing float glass are inefficient and require significant space, leading to potential damage of glass edges and suboptimal production of high-quality sections or individual panes.

Innovation Solution

A crushing system for float glass that includes a first breaking station for breaking glass along a score line in the X-direction, a second breaking station for breaking crosspieces along a score line in the Y-direction, and a transport device for moving glass and sections in a horizontal working plane without rotation, allowing for efficient and compact production.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If glass sheets are broken into blanks while oriented substantially vertically with turning stations, then complete separation of subsections is achieved, but the system requires significant space and increases complexity

Engineering Contradiction:
Improvecomplete separation of glass subsectionsVSAvoidsystem complexity with turning stations
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

Instead of breaking glass while oriented vertically and then turning it, the patent inverts the approach by breaking the glass while it remains in horizontal orientation throughout the process. The glass sheet is broken into traverses and then into sections without any turning stations, simplifying the system architecture while achieving complete separation of subsections.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The patent extracts and eliminates the turning stations from the system. By removing these complex rotational components, the system achieves the same breaking function with simpler horizontal orientation maintenance, reducing device complexity while preserving manufacturing precision.

Inventive Principle:
Principle #2Taking out (Extraction)

2Manufacturing precision

If turning stations are used to rotate glass 90° between breaking stations, then crosspieces can be broken in both X and Y directions, but space requirements increase significantly

Engineering Contradiction:
Improvebreaking of crosspieces in perpendicular directionsVSAvoidspace requirements for turning stations
Core Design Contradiction:
Manufacturing precisionVSArea of stationary object

Solution Approach 1:

Instead of rotating the glass 90° between breaking stations, the patent inverts the approach by maintaining horizontal orientation throughout. Multiple breaking stations operate in sequence on horizontally oriented glass, eliminating the need for turning stations and significantly reducing space requirements while achieving breaking in both X and Y directions.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The patent transitions from a vertical-then-horizontal breaking sequence (requiring turning) to a purely horizontal breaking sequence. By operating all breaking stations in the horizontal plane with the glass maintaining its orientation, the system achieves multi-directional breaking without the space-consuming vertical transitions.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Manufacturing precision

If complex turning technology is employed to reorient glass for subsequent breaking, then complete subdivision is achieved, but energy consumption increases

Engineering Contradiction:
Improvecomplete subdivision of glass sheetsVSAvoidenergy consumption for turning operations
Core Design Contradiction:
Manufacturing precisionVSUse of energy by moving object

Solution Approach 1:

The patent extracts and eliminates the turning operations from the process. By maintaining consistent horizontal orientation throughout the breaking process, the system achieves complete subdivision without the energy-consuming rotational movements required by turning stations.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent establishes continuous horizontal breaking operations without interruption for turning. The glass sheet moves continuously through multiple breaking stations in the same orientation, eliminating energy-wasting stop-and-turn cycles and maintaining continuous useful action throughout the subdivision process.

Inventive Principle:
Principle #20Continuity of useful action
