Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current suspension systems for events like trade fairs and exhibitions face challenges in ensuring uniform load distribution and safety, as they often require additional tensile load measuring devices and adjustments, which are costly, time-consuming, and prone to errors, leading to potential load crashes due to exceeding maximum tensile loads.
Innovation Solution
A load holder with integrated levelling and measurement modules that allow for continuous tensile load measurement and adjustment, enabling safe and reliable setup and operation of suspension systems, reducing the risk of load crashes and simplifying the setup process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If additional tensile load measuring devices are integrated into the suspension system, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent combines the tensile load measuring function directly into the load holder structure. The measurement module is integrated into the load holder body, merging the functions of load support and load measurement into a single component, thereby avoiding additional separate measuring devices
Solution Approach 2:
The load holder is designed to perform multiple functions simultaneously: it supports the load mechanically, measures the tensile load through an integrated sensor, and provides levelling adjustment. This multi-functionality eliminates the need for separate dedicated measuring devices
2Manufacturing precision
If lengths of wire ropes and chains are adjusted for correct horizontal alignment and load distribution, then positioning precision is improved, but loss of time and productivity decrease
Solution Approach 1:
The load holder incorporates an integrated levelling module that allows for preliminary adjustment of the horizontal alignment and load distribution during the setup phase. This enables correct positioning to be achieved more efficiently before the final installation
Solution Approach 2:
The levelling module provides dynamic adjustment capability, allowing the operator to modify the length or position of the load holder to achieve correct horizontal alignment and load distribution. This dynamic adjustment simplifies the setup process compared to fixed-length components
3Reliability
If the suspension system is modified after hoisting to optimize load distribution, then reliability is improved, but loss of time and productivity increase
Solution Approach 1:
The integrated measurement module enables the operator to check load distribution immediately after hoisting and make necessary adjustments using the levelling module while the system is still accessible. This preliminary verification and adjustment capability ensures optimal load distribution is achieved during setup rather than requiring later modifications

AI summary
The invention relates to a load holder (1, 200) for a suspension system for suspending loads, comprising fastening means (30, 30′) for releasably fastening a suspension module (10) to and/or a suspension module (10) on a first end of the load holder (1, 200), as well as a load bearing device (60) at a second end of the load holder (1, 200), which faces away from the first end along a longitudinal direction (L) of the load holder (1, 200). In order to reduce the risk of falling loads when using the suspension system and to simply the correct set-up of the suspension system, the load holder (1, 200) further comprises a levelling module (20, 20′) for adjusting a length (L1, L2) of the load holder (1, 200) in the longitudinal direction (L) and a measurement module (40) for measuring a tensile load between the load bearing device (60) and the first end.
