Washer Base with Segmented Structure for Narrow Cabinet Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protective packaging for large appliances, such as washing machines, fails to adequately support the centralized load during transport, as EPS bases can break apart and corrugated bases are too bulky for narrow cabinet openings, while irregularly shaped spaces around the load complicate access and stability.
Innovation Solution
A washer base comprising a bottom panel with hingedly connected flaps and a center insert shaped like a truncated pyramid, which fits between the centralized load and the cabinet, providing stability and securing the load with foam attachments, allowing for easy assembly and shipping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If EPS base is used for protective packaging, then cushioning and protection is provided, but the base breaks apart during impact
Solution Approach 1:
The base combines corrugated fiberboard with foam material to create a composite structure. The corrugated fiberboard provides structural framework and rigidity, while the foam material provides cushioning and impact absorption. This composite approach allows the base to maintain structural integrity while providing effective protection against impact forces.
2Reliability
If corrugated base is used for protective packaging, then structural integrity is maintained, but the base is too bulky to fit inside narrow cabinet opening
Solution Approach 1:
The base is divided into multiple functional segments: a flat outer perimeter portion made of corrugated fiberboard for structural support, and a central insert made of foam material for cushioning. This segmentation allows each portion to be optimized for its specific function while reducing the overall volume and enabling the base to fit through narrow cabinet openings.
3Object-affected harmful factors
If inwardly extending bottom lip is increased to reduce access to cabinet interior, then cabinet protection is improved, but access to centralized load is reduced
Solution Approach 1:
The base design incorporates different structural qualities in different locations. The outer perimeter has a larger footprint to provide cabinet protection and support, while the central insert is smaller and strategically positioned to provide load support without blocking access. This local differentiation allows both cabinet protection and load accessibility to be optimized simultaneously.
