Solution Overview

Problem

Existing transport vehicle loading structures face challenges in securely holding loads against transverse forces and longitudinal acceleration, leading to potential shifting, falling, or slipping, especially during cornering and braking, and lack sufficient adaptability and stability to accommodate varying cargo volumes and sizes.

Innovation Solution

A loading area structure where the locking bar is attached to the slats rather than just stanchions, with a diagonal lashing system using tensioning elements that can only withstand tensile loads, allowing for adjustable positioning and increased stability, ensuring the locking bar remains fixed and the slats are securely held, even under heavy loads.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the locking bar is attached only to stanchions, then the structure is simpler, but the adaptability to different cargo positions and the stability under transverse forces are reduced

Engineering Contradiction:
Improveadaptability to different cargo positionsVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The locking bar is designed to perform multiple functions: it attaches to both stanchions and side slats, providing both longitudinal and transverse load securing. This multi-functional attachment system allows the same component to adapt to different cargo positions and sizes without requiring separate specialized components for each function.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Strength

If the side slats are made flexible to absorb transverse loads, then the load securing is improved, but the slats may bend excessively and fall out of the posts

Engineering Contradiction:
Improvetransverse load absorptionVSAvoidslat retention in posts
Core Design Contradiction:
StrengthVSReliability

Solution Approach 1:

The side slats are designed with controlled flexibility parameters that allow them to elastically deform under transverse loads up to a certain threshold. The slat material and cross-section are selected to provide sufficient elastic recovery force to push the load back after lateral acceleration, while the insertion depth and receptacle design ensure the slats remain retained even during elastic deformation.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If the locking bar is made detachable at both ends, then the ease of assembly and disassembly is improved, but the reliability of load securing is reduced

Engineering Contradiction:
Improveassembly and disassembly easeVSAvoidload securing reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The detachable connection system uses simple, robust connection elements that can be quickly attached and detached multiple times. While each individual connection element is simple and replaceable, the system as a whole maintains high reliability through the redundancy of multiple attachment points (both stanchion and side slat connections) and the form-fitting design that ensures secure engagement during load securing operations.

AI summary

The structure has posts (4e, 4f) spaced apart from each other and arranged along a cargo area (2), and post latches (5e, 5f) arranged between the posts and aligned along the area. An interlocking bar (12) extending transverse to longitudinal direction of the area is provided between the posts and/or latches. A diagonal wiring (13) provided for bracing the bar has two clampers (26a, 26b). The clampers has an end attached to a joint formed in a region of the area, and another end connected to the bar such that operating lines of the bar are cross observed in the direction.
