Solution Overview

Problem

Existing connection stations for wastewater storage tanks in railway vehicles do not effectively prevent the stagnation of odorous residues, which can damage and deteriorate the vehicle's interior.

Innovation Solution

A connection station with a gutter featuring an inclined ramp that moves angularly between a lowered and raised position, allowing residues to be evacuated outside the vehicle, and includes a retention basin to collect and store any drips, ensuring the interior is protected from residue accumulation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a removable collection basin is placed under the valve connection to collect drops, then the base of the valve is protected, but the odorous residues stagnate in the pool and give off unpleasant odor

Engineering Contradiction:
Improveprotection of valve baseVSAvoidodorous residues stagnation
Core Design Contradiction:
Object-affected harmful factorsVSObject-generated harmful factors

Solution Approach 1:

The gutter is made movable between a lowered position (extending outward to receive drops) and a raised position (retracted into the vehicle). This dynamic positioning allows the system to alternate between collecting residues and emptying them, preventing stagnation while maintaining protection functionality

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The gutter is positioned to extend outward before drops fall, proactively receiving and channeling residues away from the valve base. The preliminary positioning ensures drops are captured before they can cause damage or stagnate

Inventive Principle:
Principle #10Preliminary action

2Object-affected harmful factors

If the gutter extends outward to receive drops, then residue collection is effective, but the gutter projects onto the path of movement of the hatch

Engineering Contradiction:
Improveresidue collection effectivenessVSAvoidhatch movement
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The gutter's position is dynamically adjusted based on operational needs. It extends outward during drop reception and retracts when hatch movement is required, resolving the conflict between effective residue collection and ease of hatch operation

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The gutter alternates between extended and retracted positions in periodic cycles. It extends to collect drops during normal operation, then retracts to allow hatch movement, creating a rhythmic operation that satisfies both requirements

Inventive Principle:
Principle #19Periodic action

3Object-generated harmful factors

If the gutter is made angularly movable between lowered and raised positions, then residue stagnation is prevented, but the device complexity increases

Engineering Contradiction:
Improveresidue stagnation preventionVSAvoidgutter positioning mechanism
Core Design Contradiction:
Object-generated harmful factorsVSDevice complexity

Solution Approach 1:

A single angularly movable gutter component replaces static collection basins, preventing residue stagnation through its ability to change position. This dynamic element achieves the anti-stagnation goal without requiring multiple separate mechanisms

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The movable gutter performs multiple functions: it collects drops when extended, protects the valve base when retracted, and enables hatch movement when in the retracted position. This multi-functionality reduces overall device complexity despite the added mobility feature

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