Solution Overview

Problem

Existing raised floor systems for terraces and balconies lack flexibility in use, have inadequate load transfer capabilities without adjustable feet, and suffer from poor water drainage when not using adjustable feet.

Innovation Solution

A raised floor system with detachable connectors and recesses on each outer edge, featuring a pre-tensioned spring element for positive locking, allowing horizontal and vertical connections without additional fasteners, and incorporating recesses for water drainage, with optional adjustable feet for height adjustment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If floor panels are connected without adjustable feet, then installation is simpler and cost is reduced, but load-bearing capacity and stability are insufficient

Engineering Contradiction:
Improveinstallation simplicityVSAvoidload-bearing capacity
Core Design Contradiction:
Ease of manufactureVSStrength

Solution Approach 1:

The connection system is segmented into connectors on one panel and corresponding recesses on adjacent panels. This modular approach allows panels to be connected without adjustable feet while maintaining load-bearing capacity through the distributed connection points along panel edges.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connector and recess design merges horizontal and vertical connection functions into a single integrated system. The connector features a locking element that engages with the recess to provide both lateral alignment and vertical load transfer, eliminating the need for separate adjustable feet.

Inventive Principle:
Principle #5Merging (Combining)

2Strength

If floor panels use adjustable feet for support, then load distribution is improved, but water drainage capability is reduced when feet are not used

Engineering Contradiction:
Improveload distributionVSAvoidwater drainage
Core Design Contradiction:
StrengthVSObject-affected harmful factors

Solution Approach 1:

The connector system serves multiple functions: it provides structural connection between panels, enables load distribution across the floor system, and simultaneously creates drainage pathways. The same connector-recess arrangement that ensures stability also allows water to flow through the panel assembly without requiring adjustable feet.

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

Solution Approach 2:

The solution addresses water drainage by creating three-dimensional pathways through the panel structure. The connector and recess design incorporates vertical and diagonal openings that allow water to drain through the panel thickness, adding a drainage dimension independent of the adjustable feet height adjustment function.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Ease of manufacture

If floor panels are connected only in the horizontal plane, then manufacturing is simpler, but vertical load transfer between adjacent panels is insufficient

Engineering Contradiction:
Improveconnection simplicityVSAvoidvertical load transfer
Core Design Contradiction:
Ease of manufactureVSStability of the object's composition

Solution Approach 1:

The locking element in the connector is designed to engage dynamically with the recess, providing automatic mechanical interlocking when panels are assembled. This dynamic engagement ensures vertical load transfer capability while maintaining simple manufacturing processes, as the same connector structure provides both horizontal alignment and vertical stability.

Inventive Principle:
Principle #15Dynamics
