Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle trunk cover arrangements slip during loading and unloading, causing discomfort for pets and allowing moisture accumulation, which reduces transport comfort.
Innovation Solution
A multi-layer cover arrangement featuring an open-cell foam layer with a diffusion-open surface layer and a non-slip backing layer, including a moisture-impermeable barrier layer to prevent slipping and moisture accumulation, and optionally incorporating an electrical heating device for faster drying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a limp tarpaulin is used for the protective insert, then it can be easily attached to trunk walls, but it slips inside the trunk during loading or unloading
Solution Approach 1:
The protective insert combines multiple layers including a foam layer and a surface layer with different friction characteristics. The surface layer is designed with higher friction to prevent slipping during loading operations, while the overall structure remains flexible enough for easy attachment to the trunk walls.
Solution Approach 2:
Different layers of the protective insert have different local properties: the surface layer has high friction for preventing slips, the foam layer provides absorption and flexibility, and the waterproof layer provides barrier function. This local differentiation of material properties allows the insert to simultaneously achieve ease of attachment and stability during use.
2Object-affected harmful factors
If a multi-layer material with open-cell foam layer is used, then moisture can be absorbed and evaporated, but the structure becomes more complex
Solution Approach 1:
The protective insert merges multiple functions into a single integrated component: the foam layer, waterproof layer, and surface layer are combined in one structure that simultaneously provides moisture absorption, evaporation, and protection. This integration avoids the need for separate components for each function, managing complexity while achieving comprehensive moisture management.
Solution Approach 2:
The multi-layer composite structure is designed with each layer serving a specific function: the open-cell foam layer for absorption and evaporation, the waterproof layer for preventing trunk penetration, and the surface layer for diffusion. This functional differentiation within the composite structure optimizes moisture management while maintaining a cohesive, integrated design.
