Pocket-Sized Telescoping Reaching Tool with Integrated Safety Cutter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional reaching tools are bulky, non-portable, and limited to a single function, making them unsuitable for frequent use in various tasks that require both reaching objects out of arm's reach and performing cutting operations.
Innovation Solution
A multipurpose tool with an extendable reaching member and a safety cutter, designed to be collapsible and portable, allowing it to fit in a pocket and be used for multiple tasks such as reaching high shelves and cutting materials like tape or shrink wrap.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a grabber mechanism is added to the distal end of the rod, then the tool can reach inaccessible objects, but the tool becomes too bulky to fit in a pocket
Solution Approach 1:
The extendable member is configured to extend from and retract into the handle, allowing the reaching function to be nested within the compact handle structure. When retracted, the extendable member fits inside the handle, enabling the tool to fit in a pocket while maintaining the capability to reach inaccessible objects when extended.
Solution Approach 2:
The tool transitions from a static compact form to a dynamic extendable form. The extendable member can be extended when reaching capability is needed and retracted when portability is needed, allowing the tool to adapt its size based on the operational requirement.
2Length of moving object
If the tool is made longer to reach farther objects, then the reaching capability is improved, but the tool cannot easily fit in a pocket or purse
Solution Approach 1:
The tool length is made dynamic through the extendable member that can extend to provide long reaching distance when needed, then retract to a compact size that easily fits in a pocket or purse for portability. This dynamic length adjustment resolves the contradiction between reaching distance and portability.
Solution Approach 2:
The tool is segmented into the handle and the extendable member, allowing the extendable member to be stored within the handle when not in use. This segmentation enables the tool to maintain a compact portable form while providing extended reach capability when required.
3Device complexity
If the tool is designed for a single reaching function, then the structure is simple, but the tool cannot be used for other tasks like cutting
Solution Approach 1:
The tool is designed with multiple functions by incorporating both the extendable reaching member and the safety cutter with razor blade. The handle serves as both the structural base for reaching and the housing for the cutting function, allowing a single tool to perform both reaching and cutting tasks.
Solution Approach 2:
The reaching function (extendable member) and cutting function (safety cutter with razor blade) are merged into a single integrated tool. The handle houses both the extendable member mechanism and the safety cutter, combining multiple functions into one unified device.

AI summary
A multipurpose tool includes a handle having a first end and a second end opposite of the first end. The handle is sized and shaped to fit in a hand of a user. The tool also includes an extendable member protruding from the first end of the handle and a safety cutter disposed in the second end of the handle. The extendable member has an extended configuration and a collapsed configuration. The tool is sized and shaped to fit within a pocket in an article of clothing when the extendable member is in the collapsed configuration. The extendable member has a plurality of telescoping parts and a locking mechanism for locking the telescoping parts in the extended configuration. A distal end of the extendable member includes a hook for engaging objects and pulling them towards the user.
