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

VSEngineering 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

Engineering Contradiction:
Improvestripping operation efficiencyVSAvoidgrinding wheel temperature
Core Design Contradiction:
ProductivityVSTemperature

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.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If the grinding wheel operates continuously to maintain productivity, then the low emission layer may be damaged due to overheating and contamination

Engineering Contradiction:
Improvecontinuous operation capabilityVSAvoidlow emission layer integrity
Core Design Contradiction:
ProductivityVSReliability

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.

Inventive Principle:
Principle #20Continuity of useful action

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

Engineering Contradiction:
Improvedowntime between operationsVSAvoidstripping device structure
Core Design Contradiction:
Loss of timeVSDevice complexity

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.

Inventive Principle:
Principle #5Merging (Combining)
