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

VSEngineering 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

Engineering Contradiction:
Improveloading efficiencyVSAvoidoperation complexity
Core Design Contradiction:
ProductivityVSEase of operation

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

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

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

Inventive Principle:
Principle #25Self-service

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

Engineering Contradiction:
Improveload adaptation capabilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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

Inventive Principle:
Principle #15Dynamics

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

Inventive Principle:
Principle #35Parameter changes

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

Engineering Contradiction:
Improvefixation reliabilityVSAvoidnumber of components
Core Design Contradiction:
ReliabilityVSDevice complexity

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

Inventive Principle:
Principle #1Segmentation

4Reliability

If manual tightening is used, then the system is simple, but the tightening force and reliability are insufficient

Engineering Contradiction:
Improvefixation securityVSAvoidtightening mechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

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

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

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

Inventive Principle:
Principle #25Self-service

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.
