Hand-held Handle Dispenser with Integrated Tape and Insert Strip Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current hand-held adhesive tape dispensers do not allow users to add a handle to parcels being closed, requiring external pre-manufactured handles that vary by size and necessitate additional steps and costs, and solutions involving holes in the parcel are undesirable.
Innovation Solution
A hand-held handle dispenser integrated with an adhesive tape dispenser, featuring a pulling roller and insert strip roll, allows users to create handles of varying lengths by affixing a non-adhesive zone onto the adhesive tape, eliminating the need for external handles and avoiding parcel damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If external pre-manufactured handles are used, then the parcel can be carried, but logistics and storage difficulties arise and additional steps are required
Solution Approach 1:
The patent combines the handle and the adhesive tape into a single integrated dispenser unit. The handle is formed by an insert strip that is automatically applied to the adhesive tape within the dispenser, eliminating the need for separate external handles and simplifying both storage and operation.
Solution Approach 2:
The dispenser serves multiple functions: it dispenses adhesive tape for sealing parcels and simultaneously forms handles by applying insert strips. This multi-functionality eliminates the need for separate handle storage and attachment steps.
2Ease of operation
If holes are made in the parcel for handles, then the parcel can be carried, but the integrity of the content is compromised and the parcel may deteriorate
Solution Approach 1:
The insert strip acts as an intermediary element that provides the handle function without requiring holes in the parcel. The strip is applied to the adhesive tape surface, creating a handle that attaches to the parcel externally while preserving its integrity.
3Productivity
If the translation speeds of the adhesive tape and insert strip are not identical, then the dispensing process is simpler, but crinkling occurs which may jam the dispenser
Solution Approach 1:
The system incorporates feedback mechanisms where the application element monitors and adjusts the dispensing speeds of both the adhesive tape and insert strip to maintain identical translation speeds, preventing crinkling and ensuring continuous reliable operation.
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
Enables seamless handle creation without external handles or parcel modifications, reducing costs and logistics complexity while ensuring synchronized tape and insert strip movement to prevent crinkling and jamming.
Implementation Method 1
the pulling roller is made of material with a high friction coefficient
