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

VSEngineering 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

Engineering Contradiction:
Improvelifting capabilityVSAvoidconnection stability
Core Design Contradiction:
ForceVSReliability

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #2Taking out (Extraction)

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

Engineering Contradiction:
Improvelifting force transferVSAvoidinstallation efficiency
Core Design Contradiction:
ForceVSProductivity

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.

Inventive Principle:
Principle #15Dynamics

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

Engineering Contradiction:
Improvelifting capabilityVSAvoidinstallation simplicity
Core Design Contradiction:
ForceVSEase of operation

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.

Inventive Principle:
Principle #25Self-service

Applied Scientific Principles
