Rotatable Support Dispenser for Double-Sided Adhesive Tape
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in automating the dispensing of discrete sections of double-sided adhesive tape, particularly in ensuring precise length adjustment and preventing damage to thin web materials during application.
Innovation Solution
A reconfigurable dispenser that allows users to set the required length of double-sided adhesive tape sections by adjusting the cutting zone, using a rotatable support and a cutting unit with a linearly movable sliding blade, ensuring accurate cutting without damaging the support film.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-length dispensing mechanism is used, then the device structure is simple, but the adaptability to different tape lengths is poor
Solution Approach 1:
The patent implements a rotatable support carrying the reel, allowing the cutting zone to be dynamically positioned at different angular locations. This dynamic adjustment mechanism enables the system to adapt to various tape lengths by rotating the support to the appropriate cutting position, rather than using fixed-length dispensing mechanisms for each length variant.
Solution Approach 2:
The single rotatable support structure serves multiple functions: it carries the reel, enables length adjustment through rotation, and positions the cutting zone appropriately. This multi-functional design allows one device to handle different tape lengths without requiring separate dedicated mechanisms for each length type.
2Manufacturing precision
If a cutting mechanism is used to create discrete sections, then the precision of tape length control is improved, but the risk of damaging the support film increases
Solution Approach 1:
The patent introduces a rotatable support as an intermediary carrier that holds the reel and enables precise positioning of the cutting zone without direct contact between the cutting mechanism and the support film. The cutting occurs at a controlled angular position on the reel, and the rotatable support mediates between the cutting action and the film, preventing damage while maintaining precision.
Solution Approach 2:
The system performs preliminary positioning of the cutting zone at the correct angular position on the rotatable support before cutting occurs. This preliminary action ensures that the cutting takes place at the precise location needed for the desired tape length, while the rotatable support protects the support film from damage during the cutting process.
3Productivity
If manual application of adhesive tape is used, then the complexity of the dispensing system is reduced, but the productivity and operational efficiency are lowered
Solution Approach 1:
The patent implements an automated dispensing system where the rotatable support automatically positions the cutting zone and dispenses tape sections without manual intervention. The system serves itself by automatically adjusting the cutting position based on the desired tape length and executing the cutting and dispensing operations, thereby increasing productivity while managing complexity through automated control rather than manual operations.
