Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing lifting devices for framed exterior walls do not effectively lift walls when they are already in a vertical orientation, as they typically engage the bottom plate rather than the top plate, limiting their functionality.

Innovation Solution

A bracket with a right-angled design that includes a wall space for receiving the top plate of a framed exterior wall, equipped with an attachment point for a lifting line and nuts and bolts to secure the top plate, allowing for safe and stable lifting of the wall in a vertical orientation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a lifting device engages the bottom plate of a framed exterior wall, then the wall can be lifted from a horizontal position into a vertical position, but the device cannot lift the wall when it is already in a vertical orientation

Engineering Contradiction:

Improvelifting capability in vertical orientationVSAvoidbracket structure with wall space and multiple fasteners

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Instead of engaging the bottom plate as in conventional lifting devices, this invention engages the top plate of the framed exterior wall. The bracket is positioned with its wall space receiving the top plate, and the lifting line is attached to the upper portion of the bracket, enabling lifting in vertical orientation.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The bracket is divided into distinct functional portions: a lateral portion, a lower portion, and an upper portion, each serving specific functions. The wall space is segmented to receive the top plate, while the upper portion provides the attachment point for the lifting line, allowing specialized functionality in each segment.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If a bracket engages the top plate of a framed exterior wall for vertical lifting, then the wall can be lifted in vertical orientation, but the top plate may slide out of the wall space during lifting

Engineering Contradiction:

Improvevertical lifting capabilityVSAvoidtop plate retention in wall space

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The nuts are coupled to the upper portion of the bracket in advance, and the bolts are positioned to engage the top plate before lifting begins. This preliminary securing action ensures the top plate is firmly retained in the wall space before the lifting force is applied, preventing sliding during the lifting process.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The bracket integrates multiple functions into a single structure: the wall space receives and secures the top plate, while the upper portion provides the lifting attachment point. The combination of the lateral, lower, and upper portions creates a unified system that both secures and lifts the wall.

Inventive Principle:

Principle #5Merging (Combining)

3Ease of operation

If a bracket with wall space receives the top plate insertably, then the bracket can be positioned on the framed exterior wall for lifting, but the top plate may become unstable during the lifting process

Engineering Contradiction:

Improvebracket positioning on wallVSAvoidtop plate stability during lifting

Core Design Contradiction:

Ease of operationVSStability of the object's composition

Solution Approach 1:

The top plate is inserted into the wall space and secured with bolts and nuts before the lifting process begins. This preliminary securing ensures the top plate is firmly retained in the wall space before the lifting force is applied, preventing sliding or instability during the lifting process.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The bracket structure combines multiple components (lateral portion, lower portion, upper portion, wall space, nuts, and bolts) into a composite system that provides both ease of positioning and stability during lifting. The integration of these elements creates a unified structure that secures the top plate firmly.

Inventive Principle:

Principle #40Composite materials

AI summary

A wall lifting assembly includes a bracket which includes a lateral portion forming a right angle with a lower portion and forming a right angle with an upper portion. The lower portion is spaced from the upper portion to define a wall space for insertably receiving a top plate of a framed exterior wall. The bracket has an attachment point integrated and a lifting line can engage the attachment point. In this way the framed exterior wall can be lifted with the lifting line when the bracket is positioned on the framed exterior wall. A plurality of nuts is each of the nuts is coupled to the upper portion of the bracket. A plurality of bolts is each threadable through a respective one of the nuts when the top plate is positioned in the wall space to inhibit the top plate from sliding out of the wall space when the bracket is lifted.
