Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Power

If dam construction is used to generate electrical power, then power generation capability is improved, but environmental pollution and ecological disruption worsen

Engineering Contradiction:
Improvepower generation capabilityVSAvoidenvironmental pollution and ecological disruption
Core Design Contradiction:
PowerVSObject-affected harmful factors

Solution Approach 1:

The invention extracts the power generation function from the dam structure itself, using a separate floating water wheel that can be deployed independently. This separates the energy harvesting function from the dam infrastructure, allowing power generation without the need for dam construction and its associated environmental harm.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The floating water wheel system is self-contained and can be deployed without requiring dam infrastructure. The system uses the natural water flow to rotate the paddles and generate electricity, serving itself by harnessing the kinetic energy already present in the flowing water.

Inventive Principle:
Principle #25Self-service

2Ease of manufacture

If fixed configuration water wheel is used, then manufacturing simplicity is improved, but adaptability to varying water flows worsens

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidadaptability to varying water flows
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The water wheel incorporates adjustable paddle configurations that can be dynamically modified based on water flow conditions. The paddles can be adjusted to different angles and positions to optimize performance across varying flow rates, transforming a static structure into an adaptive system.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system allows changes in operational parameters such as paddle angle, paddle immersion depth, and wheel rotation speed to adapt to different water flow conditions. By modifying these parameters, the water wheel maintains efficiency across a range of flow velocities without requiring complex manufacturing.

Inventive Principle:
Principle #35Parameter changes

3Device complexity

If constant speed connection between water wheel and generator is used, then mechanical simplicity is improved, but energy capture efficiency under varying flows worsens

Engineering Contradiction:
Improvemechanical simplicityVSAvoidenergy capture efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The system employs a variable speed drive mechanism that dynamically adjusts the connection between the water wheel and generator based on flow conditions. This allows the generator to operate at optimal speeds for electricity generation while the water wheel rotates at speeds determined by the natural water flow, decoupling the two speeds through a variable transmission system.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

A variable speed drive acts as an intermediary between the water wheel and the generator, mediating the speed mismatch between the two components. This intermediary mechanism allows the water wheel to rotate freely at flow-dependent speeds while the generator receives rotation at optimized speeds for maximum electrical output.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Stability of the object's composition

If traditional fixed power plants are used, then infrastructure stability is improved, but scalability and mobility worsen

Engineering Contradiction:
Improveinfrastructure stabilityVSAvoidscalability and mobility
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The power generation system is segmented into modular floating units that can be independently deployed and scaled. Each floating water wheel represents a discrete, self-contained module that can be added or removed based on power requirements, enabling scalable deployment from small streams to large rivers without requiring fixed infrastructure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The floating water wheel design serves multiple functions: it can be deployed in various water bodies (rivers, streams, channels), adjusted for different flow conditions, and scaled from single units to multiple units. This universal design replaces the need for location-specific fixed infrastructure with an adaptable floating platform.

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