Solution Overview

Problem

Existing trailer systems for transporting and raising elongated objects to a vertical working position are inefficient in terms of force required and trailer weight, as they often rely on conventional pivotal attachments that increase the initial force needed to raise the object and add unnecessary weight to the trailer.

Innovation Solution

A trailer apparatus with a tilting rear frame section pivotally attached to a front frame section about a horizontal tilt axis, equipped with an actuator, engagement mechanism, and lock, which allows the elongated object to be raised vertically while reducing the forces needed and minimizing trailer weight by utilizing the tilting rear frame section as a functional part of the trailer frame.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Force

If conventional pivotal attachments are used to raise elongated objects to vertical position, then the object can be raised from horizontal to vertical orientation, but the initial force required to raise the object increases and trailer weight increases

Engineering Contradiction:

Improveforce required to raise objectVSAvoidraising capability

Core Design Contradiction:

ForceVSReliability

Solution Approach 1:

The patent inverts the conventional approach by having the trailer frame tilt upward rather than the object pivot upward. The rear frame section tilts about a horizontal axis, and the engagement mechanism moves downward into engagement with the receiver, reversing the traditional motion direction to reduce required force

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent employs a dynamic tilting rear frame section that can pivot between horizontal and vertical positions, allowing the system to adapt its configuration during the raising operation. The engagement mechanism dynamically transitions from disengaged to engaged state as the frame tilts

Inventive Principle:

Principle #15Dynamics

2Reliability

If conventional pivotal attachments are used to raise elongated objects, then the object can be secured in vertical position, but the trailer weight increases

Engineering Contradiction:

Improvevertical position stabilityVSAvoidtrailer weight

Core Design Contradiction:

ReliabilityVSWeight of moving object

Solution Approach 1:

The patent merges the trailer frame structure with the raising mechanism by making the rear frame section itself the tilting element. The engagement mechanism and receiver form an integrated connection system that combines securing and raising functions into a unified structure

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The tilting rear frame section serves multiple functions: it provides structural support for the trailer, acts as the raising mechanism through its tilt motion, and incorporates the engagement mechanism for securing the object. This multi-functionality eliminates the need for separate heavy components

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A transport apparatus for moving an elongated object includes a trailer frame with a tilting rear frame section pivotally attached to a front frame section. Rear wheels are mounted under the rear frame section rearward of the tilt axis, and an actuator pivots the rear frame section upward about the tilt axis from a horizontal lowered position to a vertical raised position. An engagement mechanism on a rear end of the rear frame section rearward of the rear wheels moves downward into engagement with a receiver on the object when the rear frame section moves upward. When the rear frame section moves upward to the raised position adjacent to the object, the rear wheels are raised above the ground. A lock secures the object to the tilting rear frame. Moving the tilting rear frame section downward moves the object downward to a horizontal transport position resting on the trailer frame.
