Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dunnage partitions can damage Class A surface parts due to rigidity and lack of flexibility, and they often have sharp edges that pose safety hazards and are prone to dust contamination and fiber adhesion.
Innovation Solution
A partition made of closed-cell foam with a three-layered structure, using a lightweight, energy-absorbing inner layer and a durable outer layer, which is water-resistant and free of fibers and adhesives, allowing for curved cell formation and improved ergonomics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional rigid partitions are used to support and separate goods, then structural strength and separation capability are improved, but surface damage to Class A parts occurs due to sharp edges and lack of flexibility
Solution Approach 1:
The partition is constructed as a composite structure with an inner corrugated纸板 layer providing structural strength and an outer foam layer providing surface protection. This composite design allows the partition to maintain rigidity for structural support while the foam surface prevents damage to Class A parts.
Solution Approach 2:
An outer layer of foam material is applied over the rigid corrugated纸板 structure. This foam shell provides flexibility and softness at the surface level, preventing direct contact between sharp edges and the parts, while the underlying rigid structure maintains structural integrity.
2Stability of the object's composition
If rigid dividers are used to maintain separation of goods, then compartmentalization effectiveness is improved, but worker safety deteriorates due to sharp edges
Solution Approach 1:
The foam outer layer covers all sharp edges and corners of the rigid divider structure, creating a safe surface for worker handling while preserving the underlying structural integrity needed for effective compartmentalization.
Solution Approach 2:
The combination of rigid corrugated纸板 for structural stability and soft foam for safety creates a dual-function partition that maintains compartmentalization effectiveness while eliminating safety hazards from sharp edges.
3Ease of manufacture
If traditional partition materials like cardboard and plastic are used, then manufacturing simplicity is improved, but dust contamination and fiber adhesion occur on part surfaces
Solution Approach 1:
The foam outer layer replaces traditional adhesive-based bonding methods. The foam is applied as a continuous layer that cures to form a clean, adhesive-free surface that does not shed fibers or create dust contamination, while the inner corrugated layer provides the structural framework.
Solution Approach 2:
The foam coating creates a smooth, non-porous surface that prevents particle trapping and eliminates fiber shedding issues associated with traditional cardboard and plastic materials, providing a clean surface for Class A parts.
