Multi-purpose Tool with Hollow Handle and Folding Axes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge lies in carrying multiple essential tools for outdoor activities or emergencies without the burden of weight and volume, as separate tools are often heavy, bulky, and inconvenient to carry, leading to reduced efficiency and duration of activities.
Innovation Solution
A multi-purpose tool device that integrates various tools such as a shovel, axe, knife, saw, and hammer into a single, compact structure with a central axis and connection means, allowing tools to be housed or attached to the device, enabling selective use and storage, and providing a lightweight, versatile solution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate tools are carried for outdoor activities, then tool functionality and versatility are improved, but weight and volume increase, making carrying inconvenient
Solution Approach 1:
The patent combines multiple separate tools (shovel, axe, knife, saw, hammer) into a single integrated multi-purpose tool device. All these tools share a common handle and connection structure, merging their functions into one unified device that provides versatility while reducing the total weight and volume compared to carrying separate tools.
Solution Approach 2:
The patent creates a universal tool device that can perform multiple functions through different attachments. The central handle structure serves as a common platform for various tools, allowing one device to replace multiple specialized tools, thereby improving versatility without proportionally increasing weight.
2Adaptability or versatility
If multiple separate tools are carried for outdoor activities, then tool functionality is improved, but device volume and bulkiness increase, reducing portability
Solution Approach 1:
The patent merges multiple tools into a single compact device with shared structural components. The common handle and connection mechanism allow multiple tools to be integrated in a space-efficient manner, reducing the overall volume compared to carrying separate tools individually.
Solution Approach 2:
The patent employs a nested structure where various tool components can be stored or attached to the central handle. The tools can be positioned within or around the central structure, allowing compact arrangement that minimizes device volume while maintaining accessibility to all functions.
3Ease of operation
If tools are integrated into a single multi-purpose device, then portability and convenience are improved, but device complexity increases
Solution Approach 1:
The patent divides the multi-purpose tool into distinct modular segments (handle, connection means, various tool components). Each tool can be independently attached or detached from the central handle, allowing simple maintenance and replacement while maintaining overall device simplicity despite multiple functions.
Solution Approach 2:
The patent employs dynamic connection mechanisms that allow tools to be easily attached and detached from the central handle. The connection means provide simple engagement and disengagement actions, making the complex multi-functional device easy to operate and adapt to different needs without increasing operational complexity.

AI summary
A multi-purpose tool or apparatus includes multiple mechanical tools. In one implementation, the multi-purpose tool includes an elongated handle, a folding axe, and a folding shovel or spade, as well as a hammer or hammer-head. The folding axe is foldable between an open position and a closed position. The folding shovel is foldable among three positions, which are a closed shovel position, a 90-degree open shovel position, and a 180-degree extended shovel position. The elongated handle is hollow and includes an elongated cavity. A folding saw, as well as a knife and a sheath to protect the knife, are stored within the elongated cavity and can be removed therefrom.
