Solution Overview
Problem
Current commercial vehicle bodies face challenges in load securing, particularly in terms of complexity and cost, especially when adapting to varying loading situations, and existing solutions often impede loading and unloading processes.
Innovation Solution
A commercial vehicle body design featuring a load securing device with a carriage that can be slid along a beam, equipped with a locking device allowing for easy repositioning and adjustment, reducing the need for multiple attachment points and minimizing interference with loading operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple fixed attachment points are provided for load securing, then load securing adaptability to different loading situations is improved, but device complexity and cost increase
Solution Approach 1:
A single load securing device is designed to perform multiple functions by allowing the carriage to be positioned at different locations along the beam. The same device structure serves as both the mounting point and the positioning mechanism, eliminating the need for multiple specialized attachment points while maintaining adaptability to various loading configurations
Solution Approach 2:
The load securing device transitions from a static fixed attachment point to a dynamic system where the carriage can slide along the beam and be locked at different positions. This dynamic positioning capability provides adaptability equivalent to multiple fixed points while using a single movable device instead of multiple stationary ones
2Reliability
If rails are recessed into side walls or roof for load securing, then load securing reliability is improved, but ease of manufacture deteriorates due to complex installation
Solution Approach 1:
The load securing system is divided into separate modular components: the beam with channel serves as the structural element, while the carriage with locking device is a separate attachable component. This segmentation allows the beam to be manufactured independently without complex recesses, and the carriage can be added or adjusted independently, significantly simplifying manufacturing and assembly while maintaining secure load attachment
3Adaptability or versatility
If crossbeams with mounting rails are installed between stanchions, then load securing versatility is improved, but device complexity and cost increase due to additional components
Solution Approach 1:
The beam itself is designed with an integrated channel that serves both as a structural support element and as a guide for the load securing carriage. This multi-functional design eliminates the need for separate crossbeams and mounting rails, providing load securing versatility directly through the existing beam structure while reducing overall device complexity
Solution Approach 2:
The functions of the beam (structural support) and the mounting rail (load securing guide) are merged into a single integrated channel structure on the beam. This combination eliminates the need for separate crossbeam components and their associated mounting rails, reducing the number of parts while maintaining load securing versatility
4Adaptability or versatility
If eyelets are attached to roof rail for load securing, then load securing adaptability is improved, but ease of manufacture deteriorates due to complex attachment process
Solution Approach 1:
The load securing function is segmented from the roof rail structure into a separate carriage component that slides along the beam's channel. This segmentation allows the beam to be manufactured without complex eyelet attachment features, while the carriage provides the necessary adaptability through its movable design and integrated locking mechanism
Solution Approach 2:
The eyelet attachment function is extracted from the roof rail and replaced by a sliding carriage system that moves along the beam's channel. This extraction eliminates the need for complex eyelet attachment processes while maintaining load securing adaptability through the carriage's ability to be positioned and locked at various locations
