Solution Overview

Problem

Existing reaching and grasping tools face challenges in storage and transportation due to their telescoping poles, which are inconvenient to carry and do not fit in typical containers.

Innovation Solution

A foldable reaching and grasping tool with a hinge assembly that allows the jaw assembly to be sidelong-adjacent the trigger assembly, featuring a selectively lockable hinge and a mechanism with a cable and biasing member to maintain grip without continuous squeezing, enabling folding for compact storage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of moving object

If the pole is made telescoping to extend reach, then the reaching capability is improved, but the storage and transportation convenience deteriorates due to increased length and inability to fit in typical containers

Engineering Contradiction:
Improvereach distanceVSAvoidstorage convenience
Core Design Contradiction:
Length of moving objectVSEase of operation

Solution Approach 1:

The pole is divided into multiple telescoping segments that can be extended for reaching and collapsed for storage. The jaw assembly is separated from the trigger assembly by a hinge, allowing the jaw to be folded adjacent to the trigger assembly when not in use, effectively segmenting the tool into storable configurations.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The hinge assembly allows the jaw assembly to move from a linear extension (increasing reach in one dimension) to a folded position where the jaw is sidelong-adjacent to the trigger assembly (utilizing a different spatial dimension for storage). This dimensional transition resolves the contradiction between reach and storage.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If the hinge assembly is made selectively lockable between operating and folded positions, then the storage convenience is improved, but the device complexity increases

Engineering Contradiction:
Improvestorage convenienceVSAvoidhinge mechanism complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The hinge assembly includes a selective lock that can be engaged or disengaged by the user without requiring additional tools or complex mechanisms. The lock automatically maintains the jaw assembly in either the operating or folded position, allowing the device to self-maintain its configuration state.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If a cable and biasing member mechanism is used to maintain grip, then the ease of operation is improved by eliminating continuous squeezing, but the device complexity increases

Engineering Contradiction:
Improvegrip maintenanceVSAvoidtrigger mechanism complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The biasing member creates a periodic or sustained force that automatically maintains the jaw in a gripping position without requiring continuous user input. The cable transmits this force from the trigger mechanism to the jaw, creating an automatic grip maintenance system that activates only when the trigger is initially engaged.

Inventive Principle:
Principle #19Periodic action
