Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing packaging for sharp-edged tools, such as saw blades, poses a risk of injury due to difficulty in gripping the tool without covering the sharp edges, often requiring disposable plastic protectors.

Innovation Solution

A folding packaging design with an integrated protective section that can be folded down, allowing safe handling by enclosing the tool's sharp edges, featuring a detachable closure and a movable insert with a protective rim that can be pulled into a protruding position for easy grip.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If sharp-edged tools are placed in packaging without protective covers, then the packaging is simple and easy to manufacture, but the risk of injury during handling increases

Engineering Contradiction:

Improvepackaging simplicityVSAvoidinjury risk

Core Design Contradiction:

Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The packaging is divided into two functional parts: the outer packaging body and the inner insert with protective edge. The insert can be moved independently between retracted and protruding positions, allowing the protective function to be activated only when needed during tool removal, while maintaining packaging simplicity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The insert is designed to be movable between a retracted position (where it is completely located within the receiving space) and a protruding position (where the protective section protrudes through the access opening). This dynamic configuration allows the protective edge to be positioned optimally during tool removal while maintaining packaging simplicity.

Inventive Principle:

Principle #15Dynamics

2Object-affected harmful factors

If disposable plastic protectors are used to cover sharp edges, then the risk of injury is reduced, but the packaging complexity and waste increase

Engineering Contradiction:

Improveinjury riskVSAvoidpackaging complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The protective function is merged with the packaging structure itself through the insert with the protective edge. The protective edge is integrated into the insert, which is part of the packaging assembly, eliminating the need for separate disposable plastic protectors and reducing packaging complexity.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

Instead of using disposable plastic protectors that are discarded after use, the protective insert is designed to be reusable and can be returned to the packaging with the tool. The insert remains in the packaging after tool removal, ready to protect the tool again during the next storage cycle.

Inventive Principle:

Principle #34Discarding and recovering

3Object-affected harmful factors

If the protective section is always protruding, then safe handling is enabled, but the packaging appearance and compactness are compromised

AI summary

A folding packaging for a tool comprises an outer packaging body with a back wall section, a front wall section, a closure section, a first side wall section connecting the back wall section to the front wall section, and a second side wall section connecting the back wall section to the closure section, wherein the back wall section and the front wall section are configured to define a receiving space between them, and wherein the closure section is detachably connected to the front wall section in order to open or close an access opening to the receiving space, and an insert for placement in the receiving space, which has a protective section that can be folded down about a fold line and a receiving area for the tool, wherein the protective section has a protective edge surrounding the receiving area at least towards the access opening.The insert can be moved between a retracted position, in which it is completely located within the receiving space, and a protruding position, in which the protective section extends out of the receiving space through the access opening.
