Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional blade-based pump systems are used to transport fluid from lower to higher level, then pumping function is achieved, but fluid and its cargo (such as fish) are harmed and spillage occurs

Engineering Contradiction:

Improvesafety of fluid cargoVSAvoidharm to fish and spillage

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent removes the harmful blades from the pump system entirely, replacing them with a bladeless centrifugal design that uses rotating cylinders to generate centrifugal force for fluid transport, thereby eliminating the source of harm to fish and spillage

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces an air-water mixture as an intermediary medium that carries fish through the pump system without direct contact with mechanical blades, using aerated water flow to transport the fluid and its cargo safely from lower to higher levels

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If traditional pump systems are used to transport fluid quickly from lower to higher level, then pumping speed is improved, but energy consumption increases and efficiency decreases

Engineering Contradiction:

Improvepumping speedVSAvoidenergy consumption

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent employs periodic aeration and pulsating water flow to create efficient centrifugal motion, where intermittent air injection creates rhythmic expansion and contraction that enhances fluid transport efficiency while reducing continuous energy input requirements

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The patent changes the physical parameters of the fluid by introducing air bubbles to create an air-water mixture with different density and flow characteristics, enabling more efficient energy utilization and faster transport from lower to higher levels

Inventive Principle:

Principle #35Parameter changes
