Solution Overview

Problem

Existing drain installation methods face challenges in ensuring correct leveling and alignment without separate level tools, and protecting the drain from damage and debris during installation.

Innovation Solution

A combination of a cover plate with integrated level means and locking mechanisms that allows secure attachment to the drain for leveling and protection, with the locking means designed to be damaged upon removal to prevent incorrect reattachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a separate level tool is used to adjust drain inclination, then the drain can be leveled during installation, but the level tool may have insufficient extension for specific drains and the drain may become misaligned after installation

Engineering Contradiction:
Improveleveling accuracyVSAvoidalignment stability
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The level means is integrated into the cover plate structure, combining the protective cover function with the leveling measurement function into a single component. This eliminates the need for separate level tools and ensures the leveling reference is always available with the cover plate.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The cover plate acts as an intermediary carrier for the level means, providing a stable base for leveling measurements during drain installation. The cover plate transfers the leveling function from external tools to an integrated component that remains with the drain system.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If the drain is left uncovered during installation, then access is provided for installation work, but debris may fall into the drain and the drain may be damaged

Engineering Contradiction:
Improveinstallation accessibilityVSAvoiddebris contamination and damage
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The cover plate is installed on the drain before the final flooring or surface covering is completed. This preliminary protective action prevents debris from falling into the drain during subsequent installation work, while still allowing access when needed.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The cover plate with damaged locking means serves as a temporary protective cover for the duration of installation work. After serving its protective purpose, it is removed and discarded, replaced by the permanent drain grating.

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

3Object-affected harmful factors

If a cover plate with intact locking means is used temporarily, then protection is provided during installation, but the cover plate may be incorrectly reattached after installation

Engineering Contradiction:
Improvedrain protectionVSAvoidcover plate positioning accuracy
Core Design Contradiction:
Object-affected harmful factorsVSManufacturing precision

Solution Approach 1:

The locking means is intentionally damaged upon removal of the temporary cover plate, ensuring the cover plate cannot be reattached. This prevents incorrect repositioning while allowing the cover plate to serve its temporary protective function during installation.

Inventive Principle:
Principle #34Discarding and recovering

Solution Approach 2:

The damage to the locking means, which initially appears harmful, is actually beneficial as it prevents incorrect reattachment of the cover plate. The destruction of the locking mechanism ensures the cover plate serves only its intended temporary purpose.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

4Object-affected harmful factors

If a permanent grating is used to cover the drain, then protection is provided, but the grating cannot be used for ensuring correct levelling during installation

Engineering Contradiction:
Improvedrain protectionVSAvoidleveling capability
Core Design Contradiction:
Object-affected harmful factorsVSMeasurement precision

Solution Approach 1:

The cover plate serves a dual dynamic function during installation: it provides protection when attached and enables leveling measurements when attached. After installation, it is removed to allow permanent grating installation, transitioning from a multi-functional temporary component to a single-functional permanent component.

Inventive Principle:
Principle #15Dynamics

AI summary

A combination of a cover plate and a drain, preferably a floor drain is described. The cover plate is provided with first locking means and the drain is provided with cooperating second locking means for releasable connection of the cover plate to the floor drain. The cover plate is a temporary cover plate for use during installation of the drain. The cover plate may be used for a temporary protection of a drain during installation of the drain and for installing and adjusting the inclination of the drain without the need of separate levelling tools. To obtain this the cover plate is provided with levelling means for determining the orientation of the cover plate and thereby also the drain in relation to a horizontal or a vertical plane. The first locking means or the second locking means comprises a weakening arranged such that at least a part of the locking means is preferably damaged when the cover plate is removed from the drain to ensure that the cover is not reused.
