Solution Overview

Problem

Existing surface drainage devices face challenges with high construction site work requirements, inadequate drainage performance, low load capacity, and significant tightness issues due to water flow between segments, leading to leaks.

Innovation Solution

A surface drainage device featuring a unified, easily installable concrete body with integrated drainage openings and a drainage line, connected using concrete casting, which includes a spigot-end drainage pipe system and anti-slip tread strips for enhanced stability and hydraulic performance, eliminating the need for separate covers and reducing leakage risks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate attachments and drainage pipes are assembled on site, then installation flexibility is improved, but construction work requirements and installation complexity increase significantly

Engineering Contradiction:
Improveinstallation flexibilityVSAvoidconstruction work requirements
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The attachment and drainage pipe are merged into a single pre-assembled unit with integrated connection elements. The reception channel element includes a drain at its lowest point that can be connected watertight to the drain pipe element, forming a unified component that reduces on-site assembly complexity while maintaining installation flexibility.

Inventive Principle:
Principle #5Merging (Combining)

2Strength

If limited openings are used between attachments and drainage pipe, then structural integrity is improved, but drainage performance deteriorates

Engineering Contradiction:
Improvestructural integrityVSAvoiddrainage performance
Core Design Contradiction:
StrengthVSProductivity

Solution Approach 1:

The drainage pipe element is designed with multiple openings distributed along its length, allowing optimized drainage performance at different locations. The reception channel element features a basin design with a drain at the lowest point, creating local drainage zones that collectively improve overall drainage efficiency without compromising structural integrity.

Inventive Principle:
Principle #3Local quality

3Area of stationary object

If water flows from one attachment to another, then drainage coverage is improved, but tightness and leakage resistance deteriorate

Engineering Contradiction:
Improvedrainage coverageVSAvoidtightness
Core Design Contradiction:
Area of stationary objectVSReliability

Solution Approach 1:

The system extracts and eliminates the water flow path between attachments by providing direct drainage from each reception channel element to the drain pipe through integrated drains. The discharge pipe element receives wastewater from multiple reception channel elements independently, preventing water from flowing between attachments and eliminating sealing problems at joint locations.

Inventive Principle:
Principle #2Taking out (Extraction)

4Device complexity

If conventional channel walls without back supports are used, then device simplicity is improved, but load capacity and stability deteriorate

Engineering Contradiction:
Improvedevice simplicityVSAvoidload capacity
Core Design Contradiction:
Device complexityVSStrength

Solution Approach 1:

The reception channel element is pre-designed with a reinforced basin structure and integrated connection elements that provide inherent stability and load-bearing capacity. The watertight connection between the drain and drain pipe is pre-configured, eliminating the need for additional back supports while maintaining structural integrity and load resistance.

Inventive Principle:
Principle #10Preliminary action
