Multi-Tape Dispenser for Reversed-Conjoined Tape Strips
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tape dispensers are inadequate for simultaneously dispensing multiple tape rolls, especially when one roll needs to be reversed for adhesive alignment with another, which is essential for tasks like masking surfaces during painting or attaching lightweight materials without leaving residue.
Innovation Solution
A multi-tape dispenser design featuring rotatable tape-roll hubs on offset panels, allowing for the simultaneous dispensing of reversed-conjoined and non-reversed-conjoined tape end portions, with an integrated handle and pivotable L-shaped hook for easy handling and cutting of tape strips.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple tape rolls are dispensed individually using current dispensers, then each tape can be dispensed separately, but the user cannot simultaneously dispense reversed-conjoined tape strips for efficient masking and attachment tasks
Solution Approach 1:
The dispenser is divided into multiple compartments (first compartment for first tape roll, second compartment for second tape roll) that can independently hold and dispense different tape rolls. This segmentation allows each tape to be dispensed separately or in combination, enabling reversed-conjoined dispensing without requiring a completely complex new structure.
Solution Approach 2:
The dispenser is designed with universal functionality to handle multiple tape configurations - it can dispense tapes individually, dispense tapes in reversed-conjoined manner, or dispense tapes in non-reversed-conjoined manner. The same basic structure accommodates different dispensing modes through flexible tape path configuration, avoiding the need for multiple specialized devices.
2Adaptability or versatility
If a frame structure with lanyard forming a loop is used to hold two tape rolls, then the structure can accommodate multiple rolls, but the handle becomes cumbersome and impractical for users
Solution Approach 1:
Instead of attaching the handle to a cumbersome frame structure with lanyards, the invention inverts the approach by providing a simple handheld body that directly holds the tape rolls in compartments. The handle becomes an integrated part of the compact dispenser body rather than an attachment to a large frame, making it convenient to hold and operate like a traditional tape dispenser.
Solution Approach 2:
The invention extracts the essential function of holding multiple tape rolls from the cumbersome frame structure with lanyards. The frame structure and lanyard components are removed entirely, replacing them with a compact handheld body that has integrated compartments for holding tape rolls, thereby eliminating the handling inconvenience while preserving the multi-roll capability.
3Productivity
If tapes are dispensed with adhesive sides facing the same direction, then the dispensing path is simple, but the adhesive edges cannot be conjoined for efficient edge attachment tasks
Solution Approach 1:
The invention applies local quality by providing different tape orientation configurations in different compartments. The first tape roll can be positioned with its adhesive edge facing a specific direction, while the second tape roll in the adjacent compartment can be positioned with its adhesive edge facing the opposite direction. This localized differentiation of tape orientation enables reversed-conjoined dispensing at the point of use without requiring complex reversal mechanisms throughout the entire device.
Solution Approach 2:
The invention performs preliminary action by pre-positioning the tape rolls in the compartments with their adhesive edges oriented in specific directions before dispensing. The user loads the tapes in the desired orientations during setup, and the dispenser maintains these orientations through the dispensing process. This preliminary configuration of tape orientations eliminates the need for complex real-time reversal mechanisms during operation.

AI summary
A multi-tape dispenser, for dispensing reversed-conjoined and non-reversed-conjoined adhesive tape end portions from adhesive tape rolls, includes a housing structure configured with at least two rotatable tape-roll hubs installed perpendicularly to the front wall panel and rear wall panel so that at least one of the tape rolls installed on the rotatable tape-roll hubs is reversed and at least one adhesive edge of at least one tape roll is conjoined partially and longitudinally to a reversed adhesive edge of at least one rear tape roll when the reversed-conjoined tape end portions are being dispensed simultaneously on the same path. The multi-tape dispenser may be manufactured for use with a combination of two tape-roll hubs or three tape-roll hubs with tape rolls mounted thereto to produce reversed-conjoined tape end portions. The dispenser can also be used for dispensing at least one tape roll without being conjoined.
