Solution Overview

Problem

Existing access floor systems lack an efficient method to adjust the distance between floor panels and the foundation floor, which is crucial in clean rooms and other precision environments, and often require complex threading processes for assembly.

Innovation Solution

A support structure featuring a height-adjustable pedestal and beam element bracket system, where the pedestal is seated on top of the beam element bracket and connected using pedestal connection portions that fit into slide grooves, allowing for easy adjustment and increased stability without the need for separate threads on the beam elements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional floor support systems are used without height-adjustable pedestals, then the structure is simpler, but the distance between floor panels and foundation floor cannot be efficiently adjusted

Engineering Contradiction:

Improveadjustability of distance between floor panel and foundation floorVSAvoidcomplexity of support structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The pedestal is designed with a height-adjustable mechanism that allows dynamic modification of its length. The adjustable pedestal includes a body portion with an through-hole and a fastening member that can be positioned at different heights, enabling the support structure to adapt to various floor panel distances from the foundation floor while maintaining structural integrity.

Inventive Principle:

Principle #15Dynamics

2Reliability

If separate threads are formed on beam elements for pedestal connection, then the connection is more secure, but the manufacturing process becomes more complex

Engineering Contradiction:

Improvestability of pedestal connection to beam elementsVSAvoidmanufacturing process complexity

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The threading operation is extracted from the beam elements and relocated to the pedestal itself. The pedestal incorporates the threaded fastening member as an integral part, eliminating the need to form separate threads on the beam elements. This maintains secure threaded connections while simplifying beam element manufacturing.

Inventive Principle:

Principle #2Taking out (Extraction)

3Ease of manufacture

If the pedestal connection portion is inserted into slide groove formed in beam elements, then separate threads on beam elements are eliminated, but connection stability may be reduced

Engineering Contradiction:

Improvesimplification of manufacturing processVSAvoidstability of pedestal connection

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The slide groove and threaded fastening member are merged into a unified connection system. The pedestal connection portion includes both a slide groove for inserting into the beam element groove and a threaded fastening member for securing the connection. This combination maintains manufacturing simplicity while ensuring connection stability through the integrated dual-mechanism approach.

Inventive Principle:

Principle #5Merging (Combining)
