Detachable User Interface for Liquid-Activated Tape Dispenser
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adhesive tape dispensing machines require operators to work closely to access controls, limiting their mobility and the size of objects that can be sealed, as the machines must be placed on a work table.
Innovation Solution
A liquid-activated adhesive tape dispensing machine with a detachable and separable user interface that allows for remote operation via a device such as a keyboard, touch display, or remote control, enabling communication through cables or wireless channels, allowing the machine to be positioned at a distance from the operator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user interface is integrated into the dispensing machine, then the control is readily accessible, but the operator's freedom of movement is limited and the machine must be placed on the work table
Solution Approach 1:
The user interface is separated from the dispensing machine into a distinct, detachable component. This segmentation allows the interface to be positioned independently at a convenient location for the operator while the machine remains in its optimal position for sealing packages.
Solution Approach 2:
A data transmission cable or wireless communication channel acts as an intermediary between the user interface and the electronic controller. This intermediary enables remote operation without requiring direct physical contact between the operator and the machine.
2Ease of operation
If the machine is placed on the work table for easy access, then the controls are within reach, but the operator cannot efficiently seal very bulky packages
Solution Approach 1:
By separating the user interface from the machine body, the operator can position the machine optimally for sealing bulky packages while maintaining easy access to controls through the detached interface.
Solution Approach 2:
The operator's interaction space is extended beyond the immediate vicinity of the machine by introducing remote interface access, effectively adding a spatial dimension to the control interaction that accommodates bulky package handling.
3Adaptability or versatility
If the user interface is detached and separate from the dispensing machine, then the operator has greater freedom of movement, but the connection between interface and controller becomes more complex
Solution Approach 1:
The mechanical connection between the user interface and controller is replaced with electrical or wireless data transmission. This substitution eliminates the need for physical coupling mechanisms while maintaining reliable communication between the separated components.
Solution Approach 2:
The data transmission interface is designed to support multiple communication protocols and connection types (cable, wireless), making the system universally compatible and reducing the complexity of any single connection method.
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
This configuration provides greater operator freedom and allows for the sealing of larger packages, enabling the machine to be placed away from the work table, such as above or next to it, facilitating the handling of bulky items.
Implementation Method 1
a tank of liquid (e.g. water), means for transferring a quantity of liquid from the tank to the tape
Implementation Method 2
liquid-activated adhesive tape dispensing machine to activate an adhesive provided on the tape... the adhesive is of the type that becomes sticky when wetted

AI summary
A liquid-activated adhesive tape dispensing machine is described comprising: • a holder for a roll of tape; • a wetting system to activate adhesive provided on the tape comprising: - a tank of liquid, - means for transferring an amount of liquid from the tank to the tape, - a feed mechanism to advance the tape through the wetting system, • a tape cutting system to produce pieces of tape, • a user interface to receive commands from a user, • an electronic controller which is connected to the user interface and configured to interpret a command entered via the user interface and drive said systems to execute the command. To ease the functioning of the machine, the user interface is a device detached from the rest of the dispensing machine so as - and configured - to be able to remain at a certain distance from the dispensing machine.
