Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If synthetic flooring material is used to provide durability and cost-effectiveness, then the flooring becomes long-lasting and inexpensive, but it lacks impact absorption and spring characteristics

Engineering Contradiction:
ImprovedurabilityVSAvoidimpact absorption
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent combines synthetic flooring material with compliant inserts made of elastomeric or viscoelastic materials to create a composite structure that provides both durability and impact absorption. The composite material approach allows the rigid synthetic floor to maintain structural integrity while the compliant insert layers provide cushioning and spring characteristics.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent modifies the physical parameters of the flooring system by introducing elements with specific stiffness, elasticity, and compliance properties. The compliant inserts have controlled durometer values and elastic moduli that can be adjusted to achieve desired impact absorption and spring characteristics while maintaining overall system durability.

Inventive Principle:
Principle #35Parameter changes

2Object-affected harmful factors

If wood flooring is used to provide impact absorption and spring characteristics, then the flooring becomes safe for sports use, but it becomes expensive and requires constant maintenance

Engineering Contradiction:
Improveimpact absorptionVSAvoidcost and maintenance
Core Design Contradiction:
Object-affected harmful factorsVSEase of manufacture

Solution Approach 1:

The patent replaces expensive wood flooring with affordable synthetic materials and compliant inserts that can be easily manufactured and replaced. The modular tile system with compliant inserts provides wood-like impact absorption at a fraction of the cost, with components that can be individually replaced without constant maintenance of the entire floor system.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The patent achieves wood-like mechanical properties through synthetic materials by carefully selecting and adjusting parameters such as elastic modulus, durometer, and compliance. The compliant inserts are engineered to replicate the spring characteristics of wood while using durable, low-maintenance synthetic materials that eliminate the need for constant upkeep.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If synthetic flooring is used for outdoor installation, then the flooring becomes suitable for extended outdoor use, but it lacks adequate drainage capability

Engineering Contradiction:
Improveoutdoor suitabilityVSAvoiddrainage
Core Design Contradiction:
Adaptability or versatilityVSObject-generated harmful factors

Solution Approach 1:

The patent incorporates porous and permeable materials in the compliant inserts and tile structures to enable water drainage. The compliant inserts include channels, voids, and porous regions that allow water to pass through, preventing pooling while maintaining the structural integrity and outdoor durability of the flooring system.

Inventive Principle:
Principle #31Porous materials

Solution Approach 2:

The patent divides the flooring system into modular tiles with integrated drainage features. The compliant inserts are segmented into discrete elements with drainage channels between them, allowing water to flow through the system while maintaining stable outdoor installation across various surfaces.

Inventive Principle:
Principle #1Segmentation

4Object-affected harmful factors

If compliant inserts with specific stiffness are used to elevate the floor tile, then impact absorption is enhanced, but the device complexity increases

Engineering Contradiction:
Improveimpact absorptionVSAvoidstructure complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent uses thin, flexible compliant inserts that can be easily integrated between the synthetic floor tile and the ground surface. These inserts are constructed from elastomeric materials with controlled thickness and compliance, providing impact absorption through their flexible nature rather than complex structural mechanisms.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The patent achieves enhanced impact absorption by adjusting material parameters such as durometer, thickness, and elastic modulus of the compliant inserts rather than through complex structural designs. The inserts are engineered with specific compliance values that can be tuned to provide desired cushioning effects while maintaining simple, easy-to-install configurations.

Inventive Principle:
Principle #35Parameter changes

AI summary

A compliant insert for flexibly supporting a synthetic floor tile above a ground surface that includes one or more elongate bodies, with each elongate body having a longitudinal axis oriented parallel to a top surface of the floor tile, a top face having an attachment interface for coupling to a tile support structure extending downward from an underside of the floor tile, and a bottom face of having at least one contact flat for contacting the ground surface and at least one upwardly-directed recess for allowing liquids to flow underneath the insert. Each of the elongate bodies also has a thickness and stiffness sufficient, in an unloaded state, to elevate the support structure a distance above the ground surface.
