Tape Unrolling Device with Pivoting Storage Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for unrolling and cutting tape from a roll are cumbersome to use and not adequately secured to the tape roll, making it difficult to guide the tape through the gap and prone to uncontrolled movement during operation.
Innovation Solution
The device is designed with a foldable storage plate or roller that forms the gap, an elastic clamping bracket for secure attachment to the tape roll, and a stopper to prevent movement, ensuring easy handling and secure positioning on the roll.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the device is designed with a fixed gap structure, then the tape guidance is stable, but the device complexity increases and handling becomes cumbersome
Solution Approach 1:
The support plate is designed to be movable rather than fixed, allowing it to pivot between a storage position and a working position. This dynamic structure enables the gap to be formed only when needed, simplifying handling when the device is not in use while providing stable tape guidance during operation.
Solution Approach 2:
The device is divided into separate functional components: a base body and a movable support plate. This segmentation allows the support plate to be independently positioned and adjusted, enabling simple handling when folded up and stable gap formation when deployed.
2Reliability
If the device is secured firmly to the tape roll, then operational stability is improved, but the device cannot be easily removed or adjusted
Solution Approach 1:
The clamping bracket is designed as an elastic, movable component that can dynamically adjust its clamping force. During operation, it provides firm securing to ensure stability, but can be easily released when removal or adjustment is needed, balancing reliability with ease of operation.
Solution Approach 2:
The clamping force of the elastic bracket can vary depending on the tape roll's diameter and thickness. The elastic material allows the clamping pressure to adapt to different roll sizes, providing secure attachment across varying conditions while maintaining ease of removal.
3Reliability
If the support plate is always in the working position, then the gap is always formed for tape guidance, but the device occupies more space and is harder to store
Solution Approach 1:
The support plate can dynamically change its position between storage and working states. When not in use, it pivots to a compact storage position, reducing the device's overall volume. When needed, it moves to form the gap for reliable tape guidance, eliminating the need for constant gap formation.
Solution Approach 2:
The support plate is designed to nest within or alongside the base body when in the storage position. This nested configuration minimizes the device's external dimensions during storage while allowing full functionality when deployed.
4Reliability
If the clamping bracket is rigid, then the device is securely attached to the tape roll, but it cannot adapt to varying tape roll diameters
Solution Approach 1:
The clamping bracket is made from elastic material that can change its deformation parameters according to the tape roll's diameter and thickness. This allows the bracket to adapt its clamping force and contact geometry to different roll sizes while maintaining secure attachment.
Solution Approach 2:
The clamping bracket uses an elastic, flexible structure instead of a rigid one. This flexibility allows the bracket to conform to different tape roll dimensions and maintain reliable contact across varying roll sizes and thicknesses.

AI summary
The problem addressed by the invention is that of ensuring simple handling in the case of a device for unrolling and cutting off a strip (2) on a strip roll (3), said device having a main body (4), wherein the main body (4) has: a top side (5), having a tear-off blade (9), a gap (12), a storage plate (13) for storing the strip (2), and a roller (22); two lateral guiding surfaces (6, 7); and an underside (8). This problem is solved in that the storage plate (13) can be lateral pivoted or the roller (22) arranged after the gap (12) as viewed against the unrolling direction (11) can be inserted and locked in order to store the strip (2), wherein the storage plate (13) or the roller (22) forms the gap (12) in the end position thereof together with a rear edge (14) of the top side (5).
