Rotatable Glass Scoring Surface for Debris Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing glass substrate manufacturing processes face challenges in effectively cleaning the elongated engagement surface after scoring, leading to residual debris that can contaminate subsequent glass substrates and affect the quality of the pristine surfaces.
Innovation Solution
A glass manufacturing apparatus with a rotatable elongated engagement surface that transitions from a scoring position to a cleaning position, equipped with a scoring device such as a scoring wheel and a cleaning device featuring a brush or vacuum for debris removal, allowing for efficient cleaning and prevention of debris transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the elongated engagement surface is continuously used for scoring glass substrates, then productivity is maintained, but residual debris accumulates on the engagement surface causing cross-contamination of subsequent substrates
Solution Approach 1:
The elongated engagement surface is made rotatable to dynamically transition between scoring and cleaning positions. This dynamic repositioning allows the same surface to alternately perform scoring functions and receive cleaning treatment, resolving the contradiction between maintaining continuous productivity and preventing debris accumulation.
Solution Approach 2:
The cleaning operation is performed preliminarily on portions of the engagement surface before they are reused for scoring subsequent substrates. By rotating the surface to bring cleaned portions into the scoring position and moving contaminated portions to the cleaning position, the system prevents cross-contamination while maintaining processing continuity.
2Reliability
If the elongated engagement surface is rotated to a cleaning position for debris removal, then surface cleanliness is improved, but processing time increases due to rotation and cleaning operations
Solution Approach 1:
The cleaning operation is integrated into the continuous rotation cycle of the engagement surface rather than being a separate interruptive step. Multiple zones of the elongated surface are simultaneously in different states (scoring, cleaning, transitioning), allowing continuous productive action without complete停机 for cleaning.
Solution Approach 2:
The elongated engagement surface is effectively segmented into multiple functional zones through rotation - some portions are actively scoring while others are being cleaned. This segmentation allows parallel execution of scoring and cleaning operations, reducing the time penalty associated with cleaning.
3Object-generated harmful factors
If a cleaning device is added to the scoring apparatus, then debris removal capability is improved, but device complexity increases
Solution Approach 1:
The elongated engagement surface serves multiple functions - it acts as both the scoring surface and the cleaning surface. By rotating this universal component between scoring and cleaning positions, the patent eliminates the need for separate dedicated cleaning mechanisms, thereby adding debris removal capability without proportionally increasing device complexity.
Solution Approach 2:
The engagement surface cleans itself by being rotated to a position where it contacts the cleaning device, which removes debris from its surface. This self-service approach minimizes the complexity of the cleaning system compared to active cleaning mechanisms that would require additional actuators and control systems.
