Stackable Tray Side Wall Design for Fast Drying and High Load Capacity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stackable boxes face a trade-off between rapid drying of side walls and high load capacity, with previous designs either limiting load capacity or compromising on drying efficiency.
Innovation Solution
The design incorporates contact surfaces along side wall sections for stable stacking, with inclined top sides to promote rapid water runoff and drying, and protruding contact surfaces to prevent corner touching, allowing for higher load capacities while maintaining quick drying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the upper surfaces of the side wall sections are inclined at an angle to the stacking direction, then water and liquids run off quickly and drying is promoted, but the load-bearing capacity is limited
Solution Approach 1:
The side wall sections are segmented into multiple functional areas: inclined areas for water runoff and contact surfaces for load bearing. This segmentation allows each area to specialize in its function without compromising the other.
Solution Approach 2:
Different areas of the side wall sections have different properties: the inclined areas have a slope for rapid water drainage, while the contact surfaces have a flatter geometry optimized for load distribution and bearing capacity.
2Stability of the object's composition
If contact surfaces are added to improve load-bearing capacity, then stacking stability increases, but the drying efficiency may be compromised
Solution Approach 1:
The contact surfaces are segregated from the inclined drainage areas, creating distinct zones that perform different functions. The contact surfaces provide stacking stability while the inclined areas maintain rapid drying capabilities.
Solution Approach 2:
The contact surfaces extend beyond the adjacent inclined areas in the horizontal dimension, creating protruding support zones that provide load-bearing capacity without interfering with the vertical water runoff path on the inclined surfaces.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration enables boxes to achieve both high load capacity and rapid drying of side walls, ensuring efficient moisture removal and stable stacking, making them suitable for industrial use.
Implementation Method 1
the areas of the upper surface of the side wall sections remaining between the support surfaces are inclined at an angle to the stacking direction, allowing water and other liquids to quickly drain off the upper surfaces of the side wall sections
Implementation Method 2
This creates an air gap between the respective upper sides of the side wall sections of the lower box and the undersides of the side wall sections of the upper box, which in turn promotes the rapid drying of the side walls
