Motor-Driven Sliding Elements for Automatic Cargo Securing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing load securing systems for cargo spaces are cumbersome, difficult to operate, and disrupt the loading process, requiring manual effort and complex mechanisms for tensioning and locking, which complicates the loading and unloading of cargo.
Innovation Solution
A motor-driven system with a gearbox and transmission means is integrated into the sliding elements of the load securing devices, allowing for fully automatic operation by pressing a switch, with self-locking mechanisms to secure the load and limit switches to manage tension, ensuring the system is robust and easy to use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual lashing straps and clamping devices are used to secure cargo, then the load can be secured, but the operation becomes cumbersome and disrupts the loading process
Solution Approach 1:
The patent replaces manual mechanical lashing operations with an automated motor-driven system. Motors are integrated into the sliding elements to automatically tension the securing element, eliminating the need for manual cranking or adjustment of traditional lashing straps and clamps.
Solution Approach 2:
The system performs self-service through automatic return mechanisms. When the cargo hold door is opened or closed, or when a switch is activated, the motors automatically retract the securing element and return the sliding elements to their initial positions without requiring manual intervention.
2Extent of automation
If complex automatic return mechanisms with expander cables and deflection rollers are used, then the securing element can return automatically, but the device complexity increases
Solution Approach 1:
The patent merges the return mechanism functionality directly into the motor-driven sliding elements. The motors that tension the securing element also drive its retraction, combining two functions (tensioning and returning) into a single integrated system rather than using separate expander cables and deflection rollers.
Solution Approach 2:
The patent extracts and eliminates the complex expander cable and deflection roller subsystem from traditional automatic return mechanisms. By using motor-driven sliding elements, the system achieves automatic return functionality without requiring the elaborate cable routing and roller assemblies found in prior art.
3Extent of automation
If multiple expander rubber bands are used on both sides of the load securing net, then automatic return is achieved, but the effort and difficulty of operation increase
Solution Approach 1:
The patent replaces elastic rubber band mechanisms with motor-driven systems. The motors provide controlled tensioning and automatic retraction of the securing element, eliminating the need for operators to manually manage multiple expander rubber bands and their associated complexity.
4Force
If telescopic support masts with deflection rollers and ropes are used, then the securing element can be tensioned, but the device complexity and space requirements increase
Solution Approach 1:
The patent merges the telescopic mast structure with the sliding element housing. The sliding elements move within the vertical rails that are integrated into the mast structures, combining the tensioning mechanism and support structure into a unified system rather than separate components.
Solution Approach 2:
The patent replaces the rope-and-deflection-roller tensioning system with motor-driven sliding elements. The motors directly drive the sliding elements along the rails, providing tensioning capability without requiring external ropes, deflection rollers, or complex telescopic sections.
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 system provides a robust, user-friendly, and fully automatic solution for securing loads, reducing operational effort and ensuring the load remains securely clamped during transport, with modular design for versatility in various cargo holds.
Implementation Method 1
At least one motor, in particular electric motor, drive or a drive unit is assigned to the sliding elements
Implementation Method 2
a self-locking function, which corresponds to a locking resistance
