Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gluing units in labeling machines are difficult to clean, leading to glue burn-in and contamination, requiring manual effort and resulting in lower cleaning quality and potential environmental hazards.
Innovation Solution
The gluing unit is designed with a removable glue tank and an exchangeable glue scraper system, allowing for the integration of a cleaning unit that can be connected at the coupling point, enabling automated and enhanced cleaning processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the gluing unit elements are firmly connected to one another, then the structural stability is improved, but the cleaning effort increases significantly
Solution Approach 1:
The gluing unit is divided into separate modular elements (glue tank, glue pump, glue roller, scraper bar) that are connected via detachable coupling points. This segmentation allows individual components to be easily removed for cleaning while maintaining structural stability during operation.
Solution Approach 2:
The coupling points are designed to allow dynamic reconfiguration of the gluing unit. The connection between elements can be quickly changed from connected to disconnected state, enabling easy access to the glue roller for cleaning without permanent structural constraints.
2Ease of operation
If manual cleaning with steel brush is used, then the cleaning capability is improved, but the contamination risk of glue tank increases
Solution Approach 1:
The scraper bar and glue roller are extracted as separate removable components from the glue tank assembly. This allows cleaning to be performed on the roller outside the tank, preventing brush contaminants from entering the glue storage area while maintaining effective cleaning capability.
Solution Approach 2:
A detachable coupling point acts as an intermediary between the glue tank and the glue application components. This intermediary allows the roller to be removed for external cleaning without direct access to the tank interior, eliminating the contamination pathway while preserving cleaning effectiveness.
3Strength
If the glue tank is permanently connected, then the structural integrity is improved, but the cleaning accessibility decreases
Solution Approach 1:
The system is segmented into a stationary glue tank and movable application components (roller, scraper) connected through standardized coupling points. This maintains the tank's structural integrity while providing easy access to cleaning surfaces through component removal.
Solution Approach 2:
The coupling points are designed with universal functionality to maintain structural connection during operation and enable easy disconnection for cleaning. The same coupling mechanism serves both structural and operational needs, providing integrity when connected and accessibility when disconnected.
