Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a conventional underwater structure such as a dam is used, then coastal protection is provided, but wave energy is not effectively dissipated leading to erosion and deposition of sediments

Engineering Contradiction:
Improvewave impactVSAvoidwave energy dissipation
Core Design Contradiction:
Object-affected harmful factorsVSLoss of energy

Solution Approach 1:

The underwater structure is divided into multiple separate modules arranged in a series configuration, creating a segmented barrier that forces waves to pass through multiple sections. This segmentation increases the path length and creates turbulence at each module interface, enhancing wave energy dissipation while maintaining coastal protection functionality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The structure extends in the horizontal dimension parallel to the coastline rather than vertically like a traditional dam. This dimensional change creates a labyrinthine path that forces waves to travel along the structure, increasing exposure to friction and turbulence, thereby dissipating wave energy more effectively while still providing coastal protection.

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

2Object-affected harmful factors

If a dam structure is used to protect the coast, then coastal protection is achieved, but erosion and deposition of sediments occurs

Engineering Contradiction:
Improvecoastal protectionVSAvoidsediment erosion
Core Design Contradiction:
Object-affected harmful factorsVSLoss of substance

Solution Approach 1:

The segmented modular design creates multiple small barriers rather than one large dam, which reduces the concentrated force on sediments. The gaps between modules allow controlled water flow that prevents excessive erosion while still providing protective barrier function against storm surges and high waves.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The structure utilizes hydraulic principles by allowing water to flow through and along the modules rather than completely blocking it. This controlled hydraulic flow reduces sediment erosion by maintaining natural water movement patterns while still providing coastal protection during extreme events.

Inventive Principle:
Principle #29Pneumatics and hydraulics

3Object-affected harmful factors

If a traditional underwater structure is used, then wave barrier function is provided, but turbulence and friction are insufficient to dissipate wave energy

Engineering Contradiction:
Improvewave barrier functionVSAvoidwave energy
Core Design Contradiction:
Object-affected harmful factorsVSLoss of energy

Solution Approach 1:

The structure extends horizontally along the coastline creating a three-dimensional labyrinthine path, forcing waves to travel parallel to the structure for extended distances. This dimensional approach maximizes the surface area contact between water and structure, enhancing friction-based energy dissipation while maintaining effective wave barrier functionality.

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

Solution Approach 2:

Multiple modular sections create repeated turbulence zones as waves pass through each module, increasing the cumulative effect of friction and turbulence. The segmented design ensures that wave energy is progressively dissipated across multiple interaction points rather than in a single location.

Inventive Principle:
Principle #1Segmentation
