Deck Plate Rib Geometry for Stable Upside-Down Stacking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Deck plates stacked in pairs with ribs facing each other tend to be unstable due to small contact areas between ribs and recessed streak portions, leading to an unstable package that easily falls over.
Innovation Solution
Deck plates are designed with ribs and plane portions formed in complementary shapes, allowing them to be stacked upside down with maximized contact areas between ribs and plane portions, minimizing height and width, and using protruding streak portions to enhance stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If deck plates are stacked in the same direction with ribs facing each other, then the stacking method is simple, but the contact area between ribs and recessed streak portions is small causing an unstable state
Solution Approach 1:
The patent applies inversion by stacking deck plates in alternating orientations (upside down relative to each other) rather than in the same direction. This allows the protruding streak portions of one deck plate to contact the recessed streak portions of the adjacent deck plate, creating complementary contact surfaces that significantly increase the contact area and improve stacking stability.
2Stability of the object's composition
If deck plates are stacked while being turned upside down relative to each other, then the contact area between ribs and plane portions is maximized, but the height and width of the package increase
Solution Approach 1:
The patent employs asymmetry in the cross-sectional shapes of the ribs and plane portions, where one has a protruding configuration and the other has a recessed configuration. When stacked in alternating orientations, these asymmetric features interlock to maximize contact area while maintaining a compact package dimensions through efficient space utilization.
3Stability of the object's composition
If the contact area between ribs and recessed streak portions is increased, then the stacking stability is improved, but the complexity of the deck plate design increases
Solution Approach 1:
The patent achieves multi-functionality by designing the protruding and recessed streak portions to serve dual purposes: they enhance stacking stability through increased contact area while simultaneously acting as structural ribs that provide rigidity to the deck plate. This integration of multiple functions into a single design element avoids increasing overall design complexity.

AI summary
The application provides a technique for stacking deck plates in a stable state. A deck plate is formed of a metal plate and includes plane portions and ribs provided alternately and continuously. Bottom surfaces of the ribs and contact parts of the plane portions contacting the bottom surfaces of the ribs when deck plates in a pair are stacked while being turned upside down relative to each other are formed in complementary shapes.
