Hand-held Handle Dispenser Integrating Insert Strip Roll
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current hand-held adhesive tape dispensers do not allow users to easily add a handle to parcels without external pre-manufactured handles, which requires multiple steps, additional logistics, and can compromise parcel integrity, and existing solutions like pre-drilled holes are costly and undesirable.
Innovation Solution
A hand-held handle dispenser integrated with a handle distributor that includes a mechanism for cutting and affixing a continuous insert strip onto adhesive tape, allowing users to create handles of varying lengths without external handles or holes, using a system with a helical cutter and synchronized tape and insert strip translation to prevent crinkling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If external pre-manufactured handles are used, then handles can be added to parcels, but logistics and storage difficulties arise and additional handling steps are required
Solution Approach 1:
The patent combines the handle material (insert strip) and the application mechanism into a single integrated dispenser unit. The insert strip roll is housed within the dispenser along with the adhesive tape, allowing both handle material and application functionality to be merged in one device, eliminating the need for separate handle storage and application steps
Solution Approach 2:
The dispenser is designed to perform multiple functions: it can dispense both adhesive tape and handle material (insert strip), and the application element can apply both tape and handle. This multi-functionality allows a single device to replace multiple separate tools, reducing logistics complexity while maintaining versatility in parcel sealing and handle addition
2Adaptability or versatility
If pre-drilled holes are made in packages for handles, then handles can be attached, but parcel integrity is compromised and additional costs are incurred
Solution Approach 1:
The insert strip is pre-coated with adhesive on its back surface during manufacturing. This preliminary application of adhesive eliminates the need to create holes or openings in the parcel during the handling process, as the strip can be directly applied to the outer surface of the parcel and pressed onto the adhesive tape, thereby preserving parcel integrity
Solution Approach 2:
The insert strip acts as an intermediary element between the adhesive tape and the handle function. Instead of attaching handles directly to the parcel (which would require holes), the adhesive-coated insert strip is applied to the adhesive tape, which is already attached to the parcel. This intermediary approach allows handle attachment without compromising parcel integrity
3Adaptability or versatility
If handles of various lengths are required, then multiple pre-manufactured handle models are needed, but this increases device complexity and handling steps
Solution Approach 1:
The patent transitions from static, fixed-length pre-manufactured handles to a dynamic system where the insert strip can be dispensed in continuous or variable lengths. The user can control the length of the insert strip dispensed based on the parcel size and handle requirements, allowing adaptive handle length adjustment without needing multiple pre-manufactured models
Solution Approach 2:
The system allows changing the parameter of handle length by controlling the dispensing amount of the insert strip. Instead of selecting from discrete pre-manufactured handle models with fixed lengths, the user can dispense the insert strip to the desired length and then cut it, enabling continuous variation in handle length to match different parcel sizes and requirements
4Adaptability or versatility
If a continuous roll of insert strip is used, then handles of various lengths can be created, but a compact and efficient cutting mechanism is required within the hand-held dispenser
Solution Approach 1:
The cutting blade is integrated into the existing dispenser structure, nested within the housing that already contains the adhesive tape roll and application element. The blade is positioned to interact with the insert strip as it passes through the dispenser, utilizing the existing spatial arrangement and mechanical components of the hand-held device to accommodate the cutting function without significantly increasing overall complexity
