Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage sheds face issues with instability due to seamed connections between panels, which can lead to water ingress and increased manufacturing and installation complexity, while molded plastic materials offer design flexibility but require innovative coupling solutions.
Innovation Solution
The use of molded plastic panels with interlocked teeth couplings, foldable corner panels with embedded folding grooves, and varied depth protrusions and recesses, along with back strengthening ribs, to create a stable and seamless structure that reduces manufacturing and installation costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional seamed connections are used between panels, then assembly is simpler, but structural stability deteriorates and water ingress increases
Solution Approach 1:
The interlocked teeth coupling merges multiple panels into a unified structure through interlocking protrusions and recesses. The coupling integrates alignment features, interlocking mechanisms, and sealing surfaces into a single integrated system, eliminating separate fasteners and seals while enhancing structural stability and preventing water ingress.
2Adaptability or versatility
If molded plastic panels are used, then design flexibility improves, but manufacturing complexity increases
Solution Approach 1:
The molded plastic structure is segmented into modular panels with standardized interlocked teeth couplings. Each panel can be independently manufactured with consistent coupling features, allowing complex overall designs to be assembled from simpler, standardized components. This segmentation enables design flexibility while controlling manufacturing complexity through repetition of proven coupling elements.
3Strength
If interlocked teeth couplings with varied depth protrusions are used, then connection strength improves, but manufacturing precision requirements increase
Solution Approach 1:
The interlocked teeth coupling employs varied depth protrusions and recesses with distinct local qualities - deeper sections for primary load-bearing connections and shallower sections for alignment and secondary support. This local differentiation optimizes connection strength at critical points while maintaining reasonable manufacturing precision requirements through gradual transitions and standardized feature sets.
