Vehicle Side Lining Step Structure for Wide Cargo Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During the loading of wide cargo into vehicles with rear seats that can be folded, the cargo often entangles with the carpet and fabric of the seats, hindering loading and positioning due to lack of adequate support.
Innovation Solution
A side lining with a step structure is mounted on the vehicle's sidewall, featuring a horizontal step surface that extends inside the passenger compartment, providing a load surface to support cargo and prevent entanglement with the carpet and seat fabric.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If rear seats are folded to extend cargo space, then cargo capacity is improved, but cargo entangles with carpet and seat fabric making loading difficult
Solution Approach 1:
The side lining acts as an intermediary structure between the cargo and the seat/carpet. It provides a dedicated load surface that elevates cargo above the carpet and folded seat fabric, preventing entanglement while maintaining extended cargo space. The step structure serves as a mediator that separates cargo from the problematic surfaces below.
Solution Approach 2:
The side lining introduces a vertical dimension to cargo support by creating elevated load surfaces through step structures. Instead of cargo resting directly on the horizontal floor level, the step structures raise cargo to a higher plane, preventing contact with carpet and seat fabric while maintaining horizontal cargo capacity.
2Ease of operation
If cargo is placed directly on the floor, then loading is simple, but cargo entangles with carpet and seat fabric
Solution Approach 1:
The side lining serves as an intermediary structure that separates cargo from harmful surfaces (carpet and seat fabric). By providing an elevated load surface, it prevents direct contact between cargo and the entangling materials while maintaining ease of loading through the simple step-like structure.
Solution Approach 2:
The side lining is divided into multiple step structures at different heights and positions along the sidewall. These segmented steps create multiple elevated platforms that can accommodate different cargo sizes and shapes, preventing entanglement while maintaining loading simplicity.
3Reliability
If step structure is added to side lining, then cargo support is improved, but device complexity increases
Solution Approach 1:
The side lining is segmented into multiple step structures of varying heights positioned along the sidewall. This segmentation provides reliable cargo support for different cargo configurations while maintaining a relatively simple overall structure that can be manufactured and installed efficiently.
Solution Approach 2:
Different step structures are positioned at specific locations along the sidewall with different heights based on local cargo support needs. This local quality approach provides reliable support where needed while maintaining simplicity in areas where less support is required, optimizing the balance between reliability and complexity.

AI summary
A side lining adapted to be mounted to a sidewall of a vehicle includes a step structure defining a step surface extending horizontally and inside a passenger compartment of the vehicle. The step surface is arranged proximate to a bottom end of the side lining and defines a load surface to support a cargo.
