Adhesive Tape Dispenser With Deflection Edge for Guided Edge Application
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adhesive tape dispensers face difficulties in guided application of adhesive tape along edges, particularly due to the obstruction caused by the tape roll and the design of the dispenser, which hinders precise application near component surfaces.
Innovation Solution
A hand-held adhesive tape dispenser with a guide system and deflection edge that changes the direction of the adhesive tape post-peeling, allowing it to be applied transversely to the peeling direction, enabling closer proximity to component edges and guided application along edges by arranging the tape roll perpendicular to the application direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the adhesive tape roll is arranged in the direction of application, then the dispenser structure is simple, but the tape roll obstructs the application process and prevents precise application near edges
Solution Approach 1:
The patent introduces a deflection edge that changes the tape's path from a linear arrangement to a three-dimensional configuration. The tape is pulled off in one direction (peeling direction) and then deflected at an angle (preferably 90 degrees) to apply in a transverse direction, allowing the roll to be positioned away from the application path while still delivering tape to the target area.
Solution Approach 2:
The patent separates the peeling function and application function into distinct spatial zones by using the deflection edge. The tape roll, guide system, and deflection mechanism are positioned in one area while the application surface is in another, with the deflection edge acting as an intermediary that redirects the tape between these separated zones.
2Manufacturing precision
If a conventional guide system is used, then the dispenser design is simple, but guided sticking along edges at specific distance is difficult
Solution Approach 1:
The deflection edge is designed to work in conjunction with the tape roll's natural unwinding motion. As the user pulls the tape off the roll, the tape automatically follows the deflection edge's geometry, self-regulating its path and maintaining consistent spacing from the dispenser body without requiring additional active control mechanisms.
Solution Approach 2:
The guide system and deflection edge are pre-configured in fixed geometric relationships during dispenser manufacturing. This preliminary arrangement of guides and deflection surfaces ensures that the tape follows a predetermined path that maintains consistent spacing, eliminating the need for real-time adjustment during application.

AI summary
The invention relates to an adhesive tape dispenser, having a holder for an adhesive tape roll (2), a guide system for an adhesive tape (3) pulled off from the adhesive tape roll (2), and a deflecting edge (10) for the adhesive tape (3) that has been pulled off, which deflecting edge is arranged at the end of the guide system in the pull-off direction (A) and deflects the adhesive tape (3) that has been pulled off from the pull-off direction (A), characterized in that the deflecting edge (10) has a deflection axis, which has a component directed in the pull-off direction (A), and an affixing direction (B) is arranged transversely to the pull-off direction (A).
