Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for removing low emission and protective layers from glass panels face issues such as grinding wheel overheating and contamination due to friction and residue, which can damage the delicate low emission layer and complicate the stripping process.
Innovation Solution
A stripping device with a rotatable grinding wheel and a blowing element that directs a stream of fluid or gas to cool and clean the wheel, maintaining a constant distance through adjustable support mechanisms, ensuring efficient and continuous operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a grinding wheel is used to remove the low emission layer and/or protective layer, then the stripping operation can be performed effectively, but the grinding wheel becomes warm due to friction and dirty due to residues
Solution Approach 1:
A blowing device is introduced as an intermediary element between the grinding wheel and the environment. This device directs a stream of gas or fluid onto the grinding wheel surface, serving as a mediator to remove residues and cool the wheel without interfering with the grinding function. The blowing device acts as a separate system that addresses the thermal and contamination issues while allowing the grinding operation to continue uninterrupted.
2Productivity
If the grinding wheel operates continuously to maintain productivity, then the low emission layer may be damaged due to overheating and contamination
Solution Approach 1:
The blowing device operates continuously alongside the grinding wheel, providing uninterrupted cooling and cleaning action throughout the entire grinding process. This continuous intervention prevents temperature buildup and residue accumulation that would otherwise occur during sustained grinding operations, enabling the system to maintain both high productivity and protection of the delicate low emission layer.
3Loss of time
If the grinding wheel is cooled and cleaned during operation, then downtime between operations is reduced, but the device complexity increases due to the blowing device
Solution Approach 1:
The blowing device is integrated with the existing grinding wheel assembly, combining the cooling/cleaning function with the stripping operation. The blowing device shares the same support structure and positioning system as the grinding wheel, allowing both functions to be performed from a single operational station. This merging approach adds functionality without requiring completely separate systems, thereby limiting the increase in overall device complexity.
