Load Securing Device Support Element Force Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing load securing devices for commercial vehicles are unable to reliably absorb and divert high tensile forces, leading to increased material and labor costs when attempting to secure heavier loads, and often compromise cargo space and loading efficiency.
Innovation Solution
Incorporating an additional support element that is positioned adjacent to the indentation in the carrier profile, allowing for the dissipation of load securing forces without excessive material usage, and featuring a U-shaped lashing means with a support element that connects the legs and provides a larger cross-sectional area for force distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing load securing devices are used to absorb high tensile forces, then the reliability of load securing improves, but the material costs and device complexity increase significantly
Solution Approach 1:
The patent introduces a support element positioned beneath the carrier profile that distributes tensile forces into the third dimension (vertically downward), rather than relying solely on the horizontal strength of the carrier profile. This dimensional approach allows high forces to be absorbed without increasing the complexity of the carrier profile itself.
Solution Approach 2:
The support element acts as an intermediary component between the carrier profile and the underlying structure. It mediates the force transmission by distributing loads from the lashing means through the carrier profile to the vehicle structure, enabling reliable load securing without requiring the carrier profile to be overly complex or strong.
2Reliability
If existing load securing devices are used to absorb high tensile forces, then the reliability of load securing improves, but the material costs increase
Solution Approach 1:
By distributing forces vertically through the support element into the vehicle structure, the patent reduces the need for excessive material in the carrier profile. The support element leverages the existing structural capacity of the vehicle body, minimizing additional material requirements while achieving high load-bearing capacity.
Solution Approach 2:
The support element as an intermediary allows the use of lighter, less expensive materials in the carrier profile by transferring critical load-bearing functions to a separate component that can be optimally positioned and anchored to the vehicle structure.
3Volume of stationary object
If the lashing means is partially arranged in a depression, then the cargo space is maximized, but the ability to absorb high tensile forces is reduced
Solution Approach 1:
The support element positioned beneath the carrier profile redirects tensile forces into the vertical dimension, compensating for the reduced force absorption capacity of the depression-embedded lashing means. This allows the lashing means to be recessed for cargo space optimization while maintaining high force absorption through the support element.
Solution Approach 2:
The support element serves as a mediator that decouples the cargo space optimization function (recessed lashing means) from the force absorption function (support element anchored to vehicle structure). This separation allows both requirements to be satisfied simultaneously.
4Force
If additional support elements are added to absorb high tensile forces, then the force absorption capacity improves, but the device complexity increases
Solution Approach 1:
Instead of uniformly strengthening the entire carrier profile, the patent applies a localized support element only at the critical position where force absorption is needed beneath the carrier profile. This localized approach increases force absorption capacity with minimal additional complexity.
Solution Approach 2:
The support element utilizes the vertical dimension beneath the carrier profile to provide force absorption, rather than requiring additional horizontal components. This spatial efficiency minimizes device complexity while maximizing force absorption capacity.
