Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Certain flat, planar products like diatomaceous earth slabs are susceptible to warping or deforming during shipment, which can reduce their utility and desirability to end users.
Innovation Solution
A packaging system comprising a top cover and bottom base that applies a deflection force to the slab, maintaining its integrity by biasing it into a convex shape to counteract natural deformation due to humidity, heat, or gravity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If flat, planar products are packaged during shipment, then they are protected from external damage, but they are susceptible to warping or deforming due to humidity, heat, or gravity
Solution Approach 1:
The patent applies a preliminary counteracting force during packaging that opposes the expected deformation force. The packaging system pre-applies a convex deflection force to the slab, creating an initial convex shape that counteracts the natural tendency to deform concavely under humidity, heat, or gravity during shipment. This preliminary anti-action ensures the slab maintains its desired planar or slightly convex configuration upon delivery.
Solution Approach 2:
The packaging system performs a preliminary action by applying a controlled deflection force to the slab before shipment. The top cover and bottom base are configured to exert a predetermined convex force on the slab, establishing an initial shape bias that prevents subsequent concave deformation. This preliminary shaping action prepares the product to resist environmental stresses during transport.
2Stability of the object's composition
If a deflection force is applied to maintain product shape, then shape stability is improved, but packaging complexity increases
Solution Approach 1:
The packaging system applies local quality by concentrating the deflection force at specific contact points between the slab and the packaging structure. The top cover and bottom base are designed with specific contacting regions that apply localized pressure to create the desired convex shape. This localized approach achieves shape stability without requiring complex packaging throughout the entire structure.
Solution Approach 2:
The patent utilizes curvature by applying a convex deflection force that creates a slight spherical or bowl-like shape in the slab. The top cover and bottom base are configured to exert forces that produce this curved configuration, which naturally resists flat-slab deformation. This curvature-based approach provides shape stability through geometric form rather than complex mechanical constraints.

AI summary
A system may include a slab, and a top cover and a bottom base configured to cooperate with each other to retain the slab. The bottom base may have a planar bottom surface, a plurality of bottom-slab-contacting regions that extend above the planar bottom surface by varying heights, and four bottom-base sides. The top cover may have a planar top surface, a plurality of top-slab-contacting regions that extend below the planar top surface by varying heights, and four top-cover sides. The bottom base and the top cover may be configured such to exert pressure on the slab in a first direction at each of the four corners and exert pressure in a second direction that is opposite the first direction at the central region, so as to deflect the slab in a bowl-like manner along a width and a length of the slab.
