Telescopic Cargo Retrieval Assembly with Pivot Lock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing retrieval devices for cargo from pickup beds are inefficient as they require users to enter the bed to manually handle cargo, posing safety risks and limiting accessibility.
Innovation Solution
A telescopic cargo retrieval assembly with a handle and pivotally coupled rocker, allowing for adjustable length and a removable grapple oriented perpendicular to the member for engaging cargo, enabling retrieval without entering the bed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users enter the pickup bed to manually handle cargo, then cargo can be directly accessed, but safety risks increase and accessibility is limited
Solution Approach 1:
The patent introduces a retrieval device as an intermediary tool between the user and the cargo in the pickup bed. The device includes a handle, telescopic member, and grapple that work together to enable users to retrieve cargo without entering the bed, thus eliminating safety risks while maintaining accessibility
2Adaptability or versatility
If a fixed-length handle is used, then the device structure is simple, but the device cannot adapt to different cargo positions and bed depths
Solution Approach 1:
The patent implements a telescopic member with adjustable length that can extend and retract based on the cargo position and bed depth requirements. This dynamic adjustment capability allows the device to adapt to various operating conditions while maintaining a relatively simple overall structure through the use of standard telescopic mechanisms
3Ease of operation
If a grapple oriented parallel to the member is used, then the grapple structure is simple, but the grapple cannot effectively engage cargo when the member is extended horizontally
Solution Approach 1:
The patent employs a pivotally coupled grapple that can rotate between parallel and perpendicular orientations relative to the member. This dynamic orientation adjustment enables the grapple to effectively engage cargo regardless of the member's extension position, with the perpendicular orientation being particularly effective when the member is extended horizontally into the pickup bed

AI summary
A cargo retrieval assembly includes a handle that has a length of at least 1.2 meters and the handle may be extended into a bed of a pickup. A member is slidably positioned in the handle such that the handle and the member combine to have a telescopically adjustable length, and the member has a length of at least 1.2 meters. A rocker is pivotally coupled to the handle and the rocker engages the member when the rocker is in a locking position to retain the handle and the member at a selected length. The rocker disengages the member when the rocker is manipulated for adjusting the telescopic length of the handle and the member. A grapple is removably coupled to the member has the grapple is oriented perpendicular to the member for engaging, and thusly retrieving, cargo when the member is extended into the bed of the pickup.
