Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current wound tape products generate significant waste due to disposable plastic dispensers, while reusable dispensers made of recyclable or compostable materials are less convenient and require manual loading.

Innovation Solution

A removable cutting article designed to engage with a box containing wound tape, allowing for easy attachment and use without the need for a separate dispenser, featuring a distal and proximal end with arms and protrusions for secure engagement, and a cutting element for convenient tape access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If disposable plastic dispensers are used, then convenience is improved, but waste generation increases

Engineering Contradiction:

ImproveconvenienceVSAvoidwaste generation

Core Design Contradiction:

Ease of operationVSLoss of substance

Solution Approach 1:

The cutting article is divided into separable components: a reusable box and a removable cutting element. This allows the cutting element to be replaced while keeping the box, reducing waste compared to disposable dispensers while maintaining convenience.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The cutting element can be removed and replaced when dull or damaged, while the box is retained and reused. This recovers the reusable portion and discards only the consumable cutting element, addressing both convenience and waste concerns.

Inventive Principle:

Principle #34Discarding and recovering

2Loss of substance

If reusable dispensers are used, then waste is reduced, but ease of operation deteriorates due to manual loading

Engineering Contradiction:

Improvewaste reductionVSAvoidease of use

Core Design Contradiction:

Loss of substanceVSEase of operation

Solution Approach 1:

The cutting element is pre-attached to the box in a ready-to-use configuration. Users simply remove the entire pre-assembled unit from packaging and begin using immediately, eliminating the manual loading step required by traditional reusable dispensers.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The cutting element and box are combined into a single integrated unit that is pre-assembled before delivery to the user. This merging eliminates the need for users to perform manual assembly or loading operations.

Inventive Principle:

Principle #5Merging (Combining)

3Reliability

If a separate dispenser is used, then cutting function is improved, but device complexity increases

Engineering Contradiction:

Improvecutting functionVSAvoiddevice complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The cutting element is integrated directly onto the box, combining the storage function and cutting function into a single device. This eliminates the need for a separate dispenser while maintaining reliable cutting performance.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The box serves multiple functions: it stores the tape roll and simultaneously provides the cutting surface and cutting element. This multi-functionality eliminates the need for separate dispensing and cutting devices.

Inventive Principle:

Principle #6Universality (Multi-functionality)
