Folding Reach Extender Tool with Telescopic Segments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a tool that can reach, grasp, and release objects at various distances, being both extendable and retractable, while also being foldable for storage and transportation, and capable of operating with or without manual actuation for users with limited physical capabilities.
Innovation Solution
A folding reach extender tool with an expandable assembly, featuring a handle for manual operation, a gear assembly for adjusting extension length, and a control mechanism for automation, including retaining arms with magnetic or suction cup capabilities, and a rotary component for grasping and releasing objects, which can be mounted on a wheelchair for enhanced accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the tool is made extendable to reach remote objects, then the reach distance is improved, but the storage space requirement increases
Solution Approach 1:
The tool shaft is divided into multiple telescopic segments that can slide relative to each other, allowing the tool to extend to long reach distances while collapsing into a compact configuration for storage. The shaft includes first, second, and third segments that can be extended or retracted as needed.
Solution Approach 2:
The telescopic shaft segments are nested within each other, with the second segment sliding within the first segment, and the third segment sliding within the second segment. This nesting arrangement allows the tool to achieve extended length when needed while collapsing to a compact form for storage.
2Volume of moving object
If the tool is made retractable for compact storage, then the storage space is reduced, but the reach capability is limited
Solution Approach 1:
The tool features dynamic adjustability where the shaft segments can be extended or retracted based on the task requirements. The tool transitions between a compact retracted state for storage and an extended state for reaching remote objects, providing adaptability between storage efficiency and reach capability.
3Reliability
If the tool includes magnetic or suction cup retaining arms for secure grasping, then the grasping reliability is improved, but the device complexity increases
Solution Approach 1:
The retaining arms are designed with multi-functionality, incorporating both magnetic and suction cup grasping mechanisms in a single component. This allows the tool to grasp various types of objects (metallic and non-metallic) using different mechanisms, improving grasping reliability across different object types while avoiding the need for separate specialized components.
4Ease of operation
If the tool is designed for manual operation, then the ease of operation is improved, but the automation capability is reduced
Solution Approach 1:
The tool incorporates a self-service control mechanism where the user can manually actuate the retaining arms through a handle that engages with the rotary component. The system allows user-initiated operation without requiring external power sources or complex control systems, maintaining simplicity while providing functional automation through manual input.

AI summary
A tool to grasp objects, and to expand and/or retract while holding the objects, wherein the tool can include at least one handle disposed on a first end of an expandable assembly. At least one handle can be adapted to expand the expandable assembly when actuated or when there are a pair of handles and they are moved towards one another and retract the expandable assembly when they are moved away from one another. A gear assembly can be disposed on a second end of the expandable assembly. The tool can allow users to reach, grasp, move, and release remote objects.
