Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional adhesive tape dispensers face difficulties in preventing the tail end of the tape from rolling back onto the roll, making it hard for users to find the tail end when needed, thus complicating the usage process.
Innovation Solution
Incorporating an electrostatic generating element and an electrostatic bearing element that rub against each other to generate static electricity, preventing the tape from rolling back onto the roll by absorbing it onto the electrostatic bearing element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional adhesive tape dispenser is used, then the structure is simple, but the tape tail end rolls back onto the tape roll making it hard to find
Solution Approach 1:
The patent introduces an electrostatic bearing element as an intermediary between the tape and the electrostatic generating element. This mediator accumulates static electricity through friction with the electrostatic generating element, creating an electrostatic field that prevents the tape tail from rolling back onto the roll, thereby solving the problem of tape retrieval without significantly complicating the device structure
Solution Approach 2:
The patent replaces the purely mechanical tape retention system with an electrostatic system. Instead of relying on mechanical friction or physical barriers to prevent tape rollback, the invention uses electrostatic forces generated by the interaction between the electrostatic bearing element and the electrostatic generating element to hold the tape in place
2Reliability
If electrostatic generating element and electrostatic bearing element are added, then the tape can be absorbed and prevented from rolling back, but the device complexity increases
Solution Approach 1:
The electrostatic bearing element serves as a mediator that accumulates static electricity through friction with the electrostatic generating element. This intermediary component creates an electrostatic field that reliably prevents tape rollback while maintaining a relatively simple overall device structure
Solution Approach 2:
The patent changes the physical state of the tape by giving it an electrostatic charge. By transforming the tape from a neutral state to a charged state through friction with the electrostatic generating element, the tape's interaction with the bearing surface changes, creating reliable retention without mechanical complexity

AI summary
An adhesive tape dispenser includes a main body provided with a flattening sheet at an upper side of a first end and the flattening sheet is connected with a blade. The main body is provided with a Velcro at an underside of the first end and pivotally mounted with a first roller corresponding with the Velcro. In the process of release of adhesive tape, the adhesive tape enables the first roller and the Velcro to rub each other and generates static electricity and thus, when the adhesive tape is not used, the adhesive tape will be absorbed to the first roller and impossible to roll up back to the adhesive tape roll.
