Suspended Load Orientation Control via Dual Pivot Actuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for lifting and placing suspended loads, such as modular homes, often require them to be level and balanced, limiting flexibility in orientation adjustments, especially when placing multiple units side by side.
Innovation Solution
An apparatus with a frame and pivot axes, actuated by hydraulic systems, allows for controlled pitching and rolling movements of the suspended load, enabling intentional orientation adjustments by expanding or contracting actuators to alter the position of cable attachment points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the suspended load is lifted and placed in a level and balanced orientation, then the load is stable and safe during lifting, but the flexibility in orientation adjustments is limited when placing multiple units side by side
Solution Approach 1:
The patent applies the Dynamics principle by introducing movable pivot axes that can rotate independently in two directions (pitching and rolling). This transforms the static suspension system into a dynamic one where the frame can be intentionally oriented at various angles relative to the vertical axis, enabling flexible placement orientations while maintaining stability through controlled movement rather than fixed positioning
Solution Approach 2:
The patent segments the orientation control into two independent rotational degrees of freedom: pitching movement around a first pivot axis and rolling movement around a second pivot axis. This segmentation allows independent control of orientation parameters, enabling precise adjustment of the suspended load's orientation to facilitate side-by-side placement while maintaining overall system stability
2Device complexity
If the frame is suspended with fixed pivot axes, then the structure is simple and stable, but the ability to perform intentional orientation adjustments is limited
Solution Approach 1:
The patent transforms fixed pivot axes into movable pivot axes that can rotate independently in two directions. This dynamic configuration maintains structural simplicity by using the same basic pivot mechanism but enables complex orientation adjustments through the combination of pitching and rolling movements, achieving operational flexibility without proportionally increasing structural complexity

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables precise orientation control of suspended loads, facilitating easier placement of modular homes by allowing non-level orientations, improving the efficiency of side-by-side installation processes.
Implementation Method 1
A first actuator extends between the suspension assembly and the frame to impart a pitching movement of the frame. The first actuator expands and contracts.
Implementation Method 2
A second actuator extends between the suspension and the frame to impart a rolling movement of the frame. The second actuator expands and contracts.

AI summary
An apparatus for adjusting an orientation of a suspended load. The apparatus includes a frame suspended from a suspension assembly. The suspension assembly has a first pivot axis enabling up and down pitching movement of the frame relative to the suspension assembly and a second pivot axis enabling up and down rolling movement of the frame relative to the suspending assembly. A first actuator extends between the suspension assembly and the frame. When the first actuator expands, a first end goes down and a second end goes up. When the first actuator contracts, the first end goes up and the second end goes down. A second actuator extends between the suspension and the frame. When the second actuator expands, a first side goes down and a second side goes up. When the second actuator contracts, the first side goes up and the second side goes down.
