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

VSEngineering 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

Engineering Contradiction:
Improveease of manufactureVSAvoidsurface flatness
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

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.

Inventive Principle:
Principle #4Asymmetry

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

Engineering Contradiction:
Improveengagement simplicityVSAvoidedge support strength
Core Design Contradiction:
Ease of operationVSStrength

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.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
