Solution Overview

Problem

Current methods for drilling and milling glass sheets are inefficient, prone to vibrations, and require manual handling, leading to safety risks and increased costs, while existing machines either move the glass sheet during operation or rely on complex and costly sucker systems for stabilization.

Innovation Solution

An automatic machine with two working heads that maintains the glass sheet fixed vertically, using synchronized motion along pseudo-vertical and horizontal axes to stabilize the sheet against vibrations, allowing for precise drilling and milling operations without interfering with edge grinding processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual handling and stabilization methods are used for glass sheets during drilling and milling, then ease of operation is improved, but productivity is reduced and safety risks increase

Engineering Contradiction:
Improvemanual handlingVSAvoidproductivity
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The glass sheet supports itself vertically during processing, eliminating the need for manual handling. The sheet stands on its own edge on the support surface, and the working heads perform operations automatically without requiring operators to hold or stabilize the sheet, thus improving productivity while maintaining ease of setup.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical handling with an automated vertical processing system. The glass sheet is positioned vertically and processed by automated working heads that move along guided axes, substituting manual operations with automated mechanical systems that improve both productivity and safety.

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

2Ease of operation

If the glass sheet is moved during drilling and milling operations, then ease of operation is improved, but manufacturing precision deteriorates due to vibrations

Engineering Contradiction:
Improveease of operationVSAvoidprecision
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

Instead of moving the glass sheet horizontally during operations, the patent inverts the approach by positioning the sheet vertically and moving the working heads along vertical and horizontal axes. This inversion stabilizes the sheet against vibrations while maintaining ease of operation through automated head movement.

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

Solution Approach 2:

The patent applies localized stabilization by positioning support elements at specific locations on the vertical glass sheet. The support surface contacts the sheet at the bottom, and additional stabilization is provided by the arrangement of working heads, creating localized support points that prevent vibrations without requiring movement of the entire sheet.

Inventive Principle:
Principle #3Local quality

3Stability of the object's composition

If complex sucker systems are used for stabilization, then stability of the object's composition is improved, but device complexity increases and costs rise

Engineering Contradiction:
ImprovestabilityVSAvoiddevice complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent extracts and eliminates the complex sucker stabilization system from the processing machine. Instead of using suction cups or complex clamping mechanisms, the system relies on the vertical positioning of the glass sheet on a simple support surface, reducing device complexity while maintaining stability during operations.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces expensive, complex stabilization systems with simple, inexpensive support elements. The support surface and basic positioning mechanisms are far simpler and less costly than sucker systems, achieving adequate stability without the need for expensive specialized equipment.

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

4Ease of operation

If manual handling is used for glass sheets, then ease of operation is improved, but safety deteriorates due to sharp edges and breakage risks

Engineering Contradiction:
Improvemanual handlingVSAvoidsafety
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The glass sheet supports itself vertically during processing, eliminating the need for manual handling that exposes operators to sharp edges and breakage risks. The automated system performs all operations on the vertically positioned sheet without human contact during the critical processing phases, improving safety while maintaining operational simplicity.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical handling with automated vertical processing. The working heads are positioned and operated automatically, substituting manual operations that pose safety risks with automated mechanical systems that eliminate operator exposure to hazards from sharp glass edges.

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