Solution Overview

Problem

Conventional adhesive tape dispensers often cause hand injuries due to collisions with objects and fail to smoothly attach tape to uneven surfaces, and they lack a convenient carrying mechanism.

Innovation Solution

An adhesive tape dispenser with a protective wall and handgrip that encompasses fingers, a rotatable tape roll holder, and a pressing roller for smooth tape application, along with a hanging auxiliary for easy carrying and operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a conventional adhesive tape dispenser is used, then the dispensing operation is simple, but the user's hand may collide with the object and get hurt

Engineering Contradiction:

Improvedispensing operation simplicityVSAvoidhand injury risk

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The protective wall is pre-installed on the dispenser body to create a protective barrier before the dispensing operation begins. This preliminary structural arrangement ensures that the user's hand is protected from collision with the object during the entire dispensing process, eliminating the injury risk while maintaining operational simplicity

Inventive Principle:

Principle #10Preliminary action

2Device complexity

If a conventional adhesive tape dispenser is used, then the structure is simple, but it fails to smoothly attach tape to uneven surfaces

Engineering Contradiction:

Improvedispenser structure simplicityVSAvoidtape attachment smoothness

Core Design Contradiction:

Device complexityVSManufacturing precision

Solution Approach 1:

The pressing roller acts as an intermediary component between the tape roll and the object surface. It applies pressure to the tape as it is dispensed, ensuring smooth attachment to uneven surfaces. This additional component improves tape application quality while adding minimal complexity to the overall dispenser structure

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If a conventional adhesive tape dispenser is used, then it has basic dispensing function, but it lacks convenient carrying mechanism

Engineering Contradiction:

Improvecarrying convenienceVSAvoiddispenser structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The hanging auxiliary component serves multiple functions: it provides a carrying mechanism by allowing the dispenser to be hung on the user's wrist or belt, and it also serves as a structural support element. This multi-functional design improves carrying convenience while adding minimal complexity to the dispenser structure

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

An adhesive tape dispenser, to which a tape roll having a roll of an adhesive tape can be mounted and which is composed of a main body, a tape roll holder, and a pressing roller. The main body includes a handgrip, a protective wall connected with the handgrip, and an assembly member. A receiving space is formed between the handgrip and the protective wall. The protective wall has a contact surface formed at one side thereof opposite to the other side thereof facing the handgrip. The tape roll holder is mounted to the assembly member and includes a rotatable member for installing the tape roll thereto. The pressing roller is mounted to the main body and includes a rolling member which is rotatable relative to the main body for rolling the adhesive tape pulled out from the tape roll.
