Solution Overview

Problem

Existing floor drains require multiple spacers of different heights to accommodate various floor covering thicknesses, leading to increased construction costs and time-consuming adjustments, with spacers often being non-reusable and obstructive during installation and cleaning.

Innovation Solution

Incorporating infinitely height-adjustable spacers with threaded bore holes and adjusting screws that engage with the frame or channel body flanges, allowing for precise adjustment and removal after installation, eliminating the need for multiple spacer heights and simplifying the construction process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple spacers with different heights are provided to accommodate various floor covering thicknesses, then adaptability to different floor coverings is improved, but device complexity and construction cost increase

Engineering Contradiction:
Improveadaptability to different floor covering thicknessesVSAvoidnumber of different spacer types
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The spacer is designed with an adjustable height mechanism featuring a plate element with a threaded bore hole through which an adjusting screw extends. The adjusting screw can be rotated to change the vertical position of the plate element relative to the channel body, enabling the spacer height to be dynamically adjusted to match any floor covering thickness rather than being fixed at manufacturing.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention changes the fixed parameter of spacer height into a variable parameter that can be continuously adjusted. By incorporating the threaded bore hole and adjusting screw mechanism, the spacer's vertical dimension becomes可调 (adjustable), allowing the same spacer design to adapt to different floor covering thicknesses without requiring multiple spacer variants.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If multiple spacers with different heights are provided for different floor covering thicknesses, then adaptability is improved, but manufacturing cost increases

Engineering Contradiction:
Improveadaptability to different floor covering thicknessesVSAvoidconstruction cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The adjustable spacer design serves as a universal component that can accommodate all floor covering thicknesses through height adjustment. Instead of manufacturing multiple specialized spacer types for different thicknesses, a single universal spacer design with an adjusting screw mechanism replaces them all, simplifying the manufacturing process and reducing construction costs.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

By making the spacer height a variable parameter rather than a fixed manufacturing specification, the invention eliminates the need to produce multiple spacer variants. The adjusting screw mechanism allows the same spacer to be configured for any thickness requirement, significantly reducing manufacturing complexity and cost.

Inventive Principle:
Principle #35Parameter changes

3Ease of manufacture

If fixed-height spacers are used to adjust the distance between channel body and frame, then manufacturing simplicity is maintained, but adjustment precision and time efficiency deteriorate

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidadjustment precision
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

The spacer incorporates a dynamic adjustment mechanism where the plate element can be positioned at any height along the adjusting screw's thread. This dynamic capability allows for precise adjustment of the distance between the channel body and frame, far exceeding the fixed precision limits of pre-manufactured spacer heights.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention replaces the mechanical selection of fixed-height spacers with a threaded adjustment mechanism. Instead of choosing from discrete spacer heights, the adjusting screw provides continuous fine-adjustment capability, enabling precise positioning while maintaining manufacturing simplicity through a single spacer design.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

4Stability of the object's composition

If spacers remain in the structure after fitting the floor drain, then structural support is provided, but ease of operation deteriorates due to obstruction during installation and cleaning

Engineering Contradiction:
Improvestructural supportVSAvoidease of installation and cleaning
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The spacer is designed as a removable component that can be extracted from the structure after the floor drain is fitted and the floor covering is installed. The adjusting screw mechanism allows the spacer to be easily removed once its height-adjustment function is no longer needed, eliminating obstruction during subsequent installation and cleaning operations while providing structural support during the critical fitting phase.

Inventive Principle:
Principle #2Taking out (Extraction)
