Hinged Vehicle Load Floor Assembly With Flush Interlocking Sections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing load floor arrangements for motor vehicles are complex and expensive to manufacture and assemble due to intricate interlocking engagement surfaces, compromising ease of access and load-bearing capacity.
Innovation Solution
Engagement surfaces are limited to the cover surface of the floor element, with bearing surfaces interacting with contact surfaces to enclose the trunk recess, reducing complexity and cost while maintaining rigidity and ease of pivoting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a load floor assembly is provided for a motor vehicle boot, then the organization of the boot space is improved and items can be secured against sliding, but the device adds structural complexity to the boot assembly
Solution Approach 1:
The load floor assembly is divided into a modular structure comprising a base element, a side wall element, and a front wall element that can be independently manufactured and assembled. This segmentation allows each component to perform its specific function while contributing to the overall stability of items in the boot without requiring a completely complex integrated design.
Solution Approach 2:
The load floor assembly serves multiple functions simultaneously: it provides a stable base for items, prevents sliding through friction surfaces, offers structural support, and can be integrated with existing boot components. This multi-functionality reduces the need for separate dedicated components for each function, thereby managing overall device complexity.
2Stability of the object's composition
If a load floor assembly with friction surfaces is used, then items are secured against sliding improving stability, but the manufacturing process becomes more complex
Solution Approach 1:
Friction surfaces are applied selectively to specific local areas of the load floor assembly where items contact the structure, rather than requiring the entire assembly to have enhanced friction properties. This localized treatment achieves the anti-sliding capability while keeping the rest of the manufacturing process simple and cost-effective.
Solution Approach 2:
The load floor assembly utilizes composite construction combining base materials with friction-enhancing surface treatments or coatings. This allows the bulk material to remain simple and easy to manufacture, while the surface layer provides the necessary friction properties for securing items without complicating the overall manufacturing process.
