Tearable Tape Dispenser With Actuating Separating Edges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for separating the end of a tearable tape from a roll result in an uncontrolled, irregular separation, leading to waste, discomfort, and potential injuries due to folds or beads, and require complex manipulation that hinders proper placement on the body.
Innovation Solution
A dispenser with a pivoting body and a dispensing part featuring actuating members with movable separating edges that can be actuated by the user, allowing for precise and clean separation of the tear tape end, reducing waste and discomfort risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual separation of tear tape end from roll is performed, then the tape can be separated, but the separation location cannot be controlled precisely resulting in irregular ends
Solution Approach 1:
The patent introduces a dispenser device as an intermediary between the user and the tear tape roll. The dispenser includes a support for the roll and a separating device with separating edges that guides and controls the separation process, transforming uncontrolled manual tearing into a precise operation while maintaining ease of use
Solution Approach 2:
The separating device is designed to be actuated by the user themselves through simple manual operation. The user pulls the tear tape end and activates the separating mechanism, which automatically performs the precise separation without requiring complex manipulation or additional tools
2Reliability
If manual tearing of tear tape is performed, then separation occurs, but the end of the tape has irregularities causing discomfort and potential injury
Solution Approach 1:
The separating device acts as an intermediary that intervenes in the separation process to prevent irregularities. The separating edges guide the tear tape through a controlled path and ensure clean separation, eliminating folds, beads, and catches that would otherwise cause discomfort or injury
Solution Approach 2:
The separating device is divided into distinct functional components: a support for holding the roll, actuating members for controlling separation, and separating edges for creating clean cuts. This segmentation allows each component to perform its specific function efficiently while keeping the overall device relatively simple
3Ease of operation
If complex manipulation is used to separate tear tape, then separation can be achieved, but proper positioning on the body is hindered
Solution Approach 1:
The dispenser prepositions the tear tape end in a convenient location and orientation before separation occurs. The dispensing part holds the free end of the tear tape in readiness, so when the user activates the separating device, the tape is already positioned for immediate application to the body without requiring additional manipulation time
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The dispenser enables precise and clean separation of the tear tape end, minimizing waste and discomfort risks, while simplifying the handling process and allowing for one-handed operation, ensuring proper placement on the body.

AI summary
Dispenser for a roll of tear-off tape, comprising a reel (2) that includes: - a housing (3) with a support (6) on which the roll of tear-off tape is to be pivotally mounted; - a dispensing portion (10) with a cutting mechanism for cutting a piece of tear-off tape off the roll of tear-off tape, said cutting mechanism comprising two actuating members (20) which can be actuated by a user and each of which supports a cutting edge (16) facing each other, the actuating members (20) being movable relative to one another between a non-operational position in which the cutting edges (16) are spaced apart such that the tear-off tape can travel between the cutting edges (16), and an operational position in which the cutting edges (16) are close to one another so as to be able to come into contact with the tear-off tape.
