Anchor Point Device for Building Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing load handling devices for lifting and relocating building elements, such as wooden components, face challenges including incomplete securing against slipping, risk of soiling, pressure marks, and inefficient force transfer due to frictional connections and clamping mechanisms.
Innovation Solution
An anchor point device with a base unit that can be inserted into a recess in a building element, featuring a first and second stop means connected by a connecting element, and at least one expansion element that compresses and expands vertically to securely fix the base unit within the recess, allowing for easy lifting and reuse.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If frictional connection and clamping mechanism are used for force transfer, then lifting capability is achieved, but reliability deteriorates due to influence of surface condition and moisture content
Solution Approach 1:
The connection system is divided into separate functional elements: the base unit inserted into the recess, the expansion element for securing, and the connecting element for force transfer. This segmentation allows each component to perform its specific function optimally without the drawbacks of integrated friction-based clamping mechanisms.
Solution Approach 2:
The invention extracts the harmful frictional connection mechanism from the lifting system and replaces it with a positive mechanical connection. The expansion element provides secure anchoring through geometric interlocking rather than friction, eliminating sensitivity to surface conditions and moisture.
2Force
If fully threaded screws are used for connection, then lifting force can be transferred, but productivity deteriorates due to insufficient performance for narrow surfaces
Solution Approach 1:
The base unit is designed to be dynamically insertable into the recess, allowing quick installation without complex threading operations. The expansion element can be rapidly deployed to secure the connection, significantly improving installation efficiency compared to fully threaded screws while maintaining high lifting force capability.
3Force
If lifting loops are used for lifting, then lifting capability is achieved, but ease of operation deteriorates due to complex installation and limited usability
Solution Approach 1:
The anchor point device is designed to be self-securing through the expansion element that automatically expands within the recess to lock the base unit in place. This self-service mechanism eliminates complex installation procedures and makes the device reusable, as the same unit can be installed and removed multiple times without additional components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The anchor point device enables secure and efficient lifting of building elements by providing a stable anchor point that minimizes slipping and soiling risks, while allowing for non-destructive removal and reuse, thus overcoming the limitations of existing load handling devices.
Implementation Method 1
the at least one expansion element can be compressed by a screwing movement of the first stop means in the screwing-in direction, whereby the at least one expansion element can be expanded vertically to a longitudinal extent of the base unit
