Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional multi-component floor drain fittings are used, then structural integrity can be maintained, but installation complexity and time increase significantly

Engineering Contradiction:
Improveinstallation simplicityVSAvoidnumber of components
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines multiple traditional drain fitting components (drain body, mounting flange, and fastening elements) into a single integrated one-piece structure. This merging eliminates the need for separate assembly steps and reduces the number of individual parts while maintaining the structural integrity and functional performance of the traditional multi-component system.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If traditional floor drain fittings with separate mounting flanges are used, then secure attachment is achieved, but installation time and labor increase

Engineering Contradiction:
Improveattachment securityVSAvoidinstallation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The mounting flange is integrated directly into the drain body as a unified component, eliminating separate attachment steps. The one-piece construction allows the entire assembly to be installed as a single unit while maintaining secure attachment through the integrated flange design with pre-positioned fastening features.

Inventive Principle:
Principle #5Merging (Combining)

3Productivity

If multi-component drain fittings are used, then structural integrity is maintained, but the installation process becomes cumbersome and time-consuming

Engineering Contradiction:
Improveinstallation efficiencyVSAvoidnumber of assembly steps
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent integrates the drain body, mounting flange, and fastening components into a single molded one-piece structure, reducing the installation process from multiple assembly steps to a single placement operation. This significantly improves installation efficiency while maintaining all necessary structural and functional characteristics.

Inventive Principle:
Principle #5Merging (Combining)

4Adaptability or versatility

If traditional separate-piece drain fittings are used, then adaptability to different installation conditions is achieved, but the installation process becomes complex

Engineering Contradiction:
Improvecompatibility with flooring materialsVSAvoidinstallation complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The integrated one-piece design maintains adaptability to various flooring materials (wood, concrete, etc.) through the unified mounting flange structure, while simplifying the installation process by eliminating the need to assemble multiple components on-site. The single-piece construction allows for straightforward installation regardless of the substrate type.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A one-piece drain fitting with an integral mounting flange. The mounting flange has a plurality of holes for quickly securing the mounting flange to the top or bottom side of a wood sub-floor with screws or nails. The drain fitting can alternatively be installed in pre-cast or cast-in-place concrete without the use of fasteners. The drain fitting can be provided with a removable temporary cover for keeping out debris during construction.
