Modular pad
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional modular pads with vertical sides are prone to uneven surfaces and edge deformation due to uneven laying and lack mutual support, leading to depressed and permanently deformed edges.
Innovation Solution
The modular pad design features oblique sides with complementary convex and concave corner portions that allow for quick and accurate engagement, ensuring flatness and preventing edge deformation, using flexible layers with varying hardness for enhanced support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional modular pads use vertical sides for engagement, then the structure is simple and easy to manufacture, but the surface becomes uneven and edges become depressed and permanently deformed
Solution Approach 1:
The patent applies asymmetry by changing the side shape from vertical to oblique. The first side and second side of each pad are configured with oblique surfaces that complement each other, creating an asymmetric engagement structure. This asymmetric design allows the pads to interlock at an angle, providing mechanical support that prevents edge depression and maintains surface flatness, while still being simple to manufacture using standard cutting processes.
2Ease of operation
If conventional modular pads use vertical sides, then the engagement process is simple, but the pads cannot provide mutual support and edges easily become depressed
Solution Approach 1:
The patent introduces a new dimensional aspect by using oblique surfaces instead of vertical sides. The oblique first surface and second surface create a three-dimensional interlocking mechanism where pads engage at an angle. This dimensional change allows the pads to provide mutual support through the inclined surfaces, distributing loads and preventing edge depression while maintaining simple engagement through the complementary oblique geometry.
