Truck Load Securing Belt with Spring-Loaded Deflection Rollers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing load-securing belt systems for trucks and trailers are cumbersome and inefficient in both the introduction and fixation of loads, failing to securely adapt to the outer contour and size of the load.
Innovation Solution
A load-securing belt system where the restraining strap is guided over all corners via deflection rollers, with upper rollers attached to spring or telescopic means that move towards the load upon tightening, allowing for adjustable and secure fixation, and optionally featuring a remotely controllable ratchet and force-sensing mechanisms for enhanced reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the belt is stretched over the load and fastened manually, then the load can be secured, but the process is cumbersome and inefficient
Solution Approach 1:
The patent replaces manual mechanical operations with automated mechanical systems. The ratchet mechanism automatically winds and tightens the belt, eliminating the need for manual stretching and fastening operations, thereby significantly improving loading efficiency while reducing operational complexity
Solution Approach 2:
The belt system performs self-tightening through the ratchet mechanism that automatically winds the belt when tension is applied. The system serves itself by automatically securing the load without requiring continuous manual intervention, making the loading process more efficient and simpler to operate
2Adaptability or versatility
If fixed belt length is used, then the structure is simple, but the load cannot be securely adapted to different sizes and shapes
Solution Approach 1:
The patent introduces a variable-length belt system with a ratchet mechanism that allows dynamic adjustment of the belt length during operation. The belt can be extended or retracted as needed to accommodate different load sizes and shapes, providing adaptability while maintaining a relatively simple overall structure through the use of a single adjustable component rather than multiple fixed-length belts
Solution Approach 2:
The system changes the key parameter of belt length dynamically through the ratchet mechanism. By allowing the belt length to vary according to the load requirements, the system achieves high adaptability to different load configurations while keeping the structural complexity low through a straightforward length-adjustment mechanism
3Reliability
If multiple deflection rollers are added to guide the belt around the load, then the fixation becomes more secure, but the device complexity increases
Solution Approach 1:
The patent divides the belt path into multiple segments guided by several deflection rollers positioned at different locations. Each roller independently guides a portion of the belt around specific corners or edges of the load, creating multiple contact points that collectively enhance fixation reliability while keeping each individual component simple and the overall system manageable
4Reliability
If manual tightening is used, then the system is simple, but the tightening force and reliability are insufficient
Solution Approach 1:
The patent replaces manual tightening with an automated ratchet mechanism that provides consistent and reliable tightening force. The ratchet mechanism automatically winds the belt and maintains tension, ensuring secure fixation without requiring significant manual effort, thereby improving reliability while adding only a relatively simple automated mechanical component
Solution Approach 2:
The ratchet mechanism provides self-tightening functionality by automatically winding the belt when tension is applied and maintaining constant tension throughout the loading process. This self-service capability ensures reliable fixation without requiring continuous manual adjustment or complex control systems

Function Achieved in This Case
Enables secure and adaptable load fixation tailored to the load's size and shape, with automated and monitored tightening, ensuring reliable load restraint across various loading profiles and configurations.
Implementation Method 1
at least the upper deflecting rollers are attached to spring or telescopic means in such a way that they can be moved towards the load by tightening the restraining strap
Implementation Method 2
the upper deflection rollers can be moved away from the upper corner position by tightening the belt at the bottom of the said ratchet on spring elements

AI summary
The invention relates to a load securing strap system for trucks or truck trailers, according to the preamble of claim 1. In order to improve a load securing strap system in such a way that both the loading and securing of the load are simplified, and that secure load securing is also ensured, it is proposed according to the invention that the securing strap (10) is guided over all corners of the loading clearance profile via deflection pulleys (11, 12), and that at least the upper deflection pulleys (11, 12) are attached to spring or telescopic means (21) such that these can be moved onto the load by tightening the securing strap (10) and can be positioned on the same.
