Solution Overview

Problem

Existing seepage block elements for underground water retention lack stability and efficient stacking capabilities, leading to asymmetrical load distribution and potential instability during transportation and underground installation.

Innovation Solution

The seepage block element features a square base with hollow columns that are mirror-symmetrical with respect to the base's center lines but not its 45-degree diagonals, allowing for symmetrical load distribution when stacked and rotated 90 degrees, enabling secure and stable underground arrangement and efficient transportation by allowing columns to interlock and distribute forces evenly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If seepage block elements are designed for stacking during transport, then transportation efficiency is improved, but stability and load distribution during underground installation deteriorate

Engineering Contradiction:
Improvetransportation efficiencyVSAvoidstability during underground installation
Core Design Contradiction:
ProductivityVSStability of the object's composition

Solution Approach 1:

The seepage block elements are designed with recesses and protrusions that allow one element to be nested within another during transportation, creating a compact stacked arrangement. The hollow columns of upper elements fit into the structural spaces of lower elements, enabling space-efficient transport while maintaining structural integrity.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The design incorporates asymmetric features where the stacking configuration differs from the underground installation configuration. During transport, elements stack vertically with columns aligned, while during installation, elements are arranged with 90-degree rotation to achieve symmetrical load distribution through the mirrored column patterns on opposite edges.

Inventive Principle:
Principle #4Asymmetry

2Stability of the object's composition

If columns are arranged for symmetrical load distribution, then stability during underground operation is improved, but stacking capability for transportation deteriorates

Engineering Contradiction:
Improvesymmetrical load distributionVSAvoidstacking capability
Core Design Contradiction:
Stability of the object's compositionVSProductivity

Solution Approach 1:

The base wall is segmented with columns arranged in specific patterns where opposite edges have mirrored column arrangements. This segmentation allows the structure to achieve symmetrical load distribution when rotated 90 degrees during underground installation, while the same segmented features provide alignment references for stacking during transportation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The design exploits rotational transformation between two operational dimensions: the transportation dimension where columns align vertically for stacking, and the installation dimension where 90-degree rotation creates symmetrical load paths. The mirrored column patterns on opposite edges enable this dimensional switching capability.

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

3Strength

If seepage block elements are designed with interlocking columns, then structural integrity is improved, but device complexity increases

Engineering Contradiction:
Improvestructural integrityVSAvoiddesign complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

Multiple functions are merged into the column structure: the columns serve as load-bearing elements, interlocking features for stacking during transport, and alignment references for rotational positioning during installation. The hollow columns integrate structural support with the interlocking mechanism, eliminating the need for separate components.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The column structure is designed as a universal element that performs multiple functions: providing structural strength, enabling vertical stacking through recess-protrusion interfaces, and facilitating 90-degree rotational alignment during installation. The mirrored column patterns on opposite edges create a multi-functional system that adapts to different operational requirements.

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

AI summary

A drainage block element (1, 26, 41, 45) with a base wall (2, 31, 42, 46) to which hollow columns (3, 28, 36, 37, 38, 39, 43, 47, 50, 51, 52) are connected. With two identical drainage block elements oriented in the same direction, the columns of the first drainage block element can be inserted into the columns of the second drainage block element, and a stack of the two identical and oriented drainage block elements can be formed. The drainage block element exhibits an axial symmetry of 180° or less when rotated about an axis of rotational symmetry (A1, A2, A4, A5).In the case of two identical drainage block elements arranged rotated relative to each other by 90° or less about an axis of rotation (A, A3, A4, A5) perpendicular to the base wall, the column tips of the first drainage block element can be inserted into the column tip receptacles (4, 29, 32, 33, 34, 35, 49, 53, 54, 55) of the second drainage block element, and an operating distance (D1) can be formed between the underside of a first base wall and the top side of a second base wall. A drainage block (16) comprises at least one drainage block element and a base plate (6, 27) with receptacles (7) for the column tips. A transport unit comprises a plurality of identical, uniformly oriented drainage block elements and a transport plate (10) or a base plate.
