Solution Overview

Problem

Existing adjustable support systems for raised floors are impractical due to their time-consuming adjustment process and lack of immediate height identification.

Innovation Solution

A support system comprising a lower rotor with a spiral profile and an upper rotor, allowing rapid height adjustment through relative rotation, with grip features and clear height markings for precise identification.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If adjustable support systems are used to vary floor height, then adaptability is improved, but adjustment time increases

Engineering Contradiction:

Improvefloor height adjustabilityVSAvoidadjustment time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent employs spiral (curved) profiles on both rotors that convert rotational motion into vertical displacement. The curved spiral surfaces enable continuous height adjustment through simple rotation, transforming a potentially complex linear adjustment mechanism into an efficient rotational system that rapidly achieves any desired height within the spiral's range.

Inventive Principle:

Principle #14Spheroidality (Curvature)

Solution Approach 2:

The support system uses two rotors capable of relative rotation to dynamically adjust the floor height. The upper rotor rotates relative to the lower rotor on the spiral profile, creating dynamic height variation. This dynamic mechanism allows continuous adjustment during installation rather than requiring static pre-set heights, significantly reducing adjustment time while maintaining full adaptability.

Inventive Principle:

Principle #15Dynamics

2Measurement precision

If height markings are added to identify adjustment level, then measurement precision is improved, but device complexity increases

Engineering Contradiction:

Improveheight identification accuracyVSAvoidmarking system complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent applies visual markings (contrasting colors or patterns) on the rotors to indicate height positions. These markings are strategically placed on the spiral surfaces so that during rotation, they provide clear visual feedback about the current height setting. The use of simple visual contrast rather than complex digital or mechanical indicators maintains low device complexity while achieving high measurement precision for height identification.

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Enables quick and practical height adjustment of raised floors with immediate identification of the set height, enhancing operational efficiency.

Implementation Method 1

The lower rotor comprises a spiral profile on which an upper inclined plane is defined, and the upper rotor comprises a spiral element on which a lower inclined plane is defined. The upper inclined plane rests on the lower inclined plane, so that as the upper rotor rotates relative to the lower rotor, the upper rotor is raised or lowered relative to the lower rotor depending on the direction of rotation.
