Solution Overview

Problem

Existing wave power generating installations face energy loss due to friction from seawater flowing through openings and accumulation of barnacles and scales, which obstruct the movement of float bodies, reducing efficiency.

Innovation Solution

A sea wave power generating apparatus with a floating panel that oscillates within a frame, utilizing a level controlling device to maintain submersion under varying water levels and a power generating device with a rack and pinion mechanism to convert kinetic energy into electricity, eliminating friction losses and barnacle accumulation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If seawater flows through openings and walls of the chamber, then the wave energy can enter the chamber, but friction loss occurs reducing the output energy

Engineering Contradiction:
Improvefriction lossVSAvoidenergy output
Core Design Contradiction:
Loss of energyVSProductivity

Solution Approach 1:

The patent removes the chamber structure with openings and walls that cause friction loss. Instead of using a chamber, the invention employs a float body that moves reciprocally within the chamber, allowing wave energy to be captured without the harmful friction effects of water flowing through openings and along walls.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The float body acts as an intermediary element between the incoming waves and the power generation mechanism. It transfers the wave energy through reciprocative motion without requiring water to flow through restrictive openings, thereby eliminating friction loss while maintaining energy transfer efficiency.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If barnacles and organisms accumulate in the aperture, then the float body movement is obstructed, but the aperture is necessary for wave energy entry

Engineering Contradiction:
Improvemovement smoothnessVSAvoidbarnacle accumulation
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent eliminates the aperture structure that is susceptible to barnacle accumulation. By removing the traditional chamber opening and instead using a float body that moves within the chamber, the design eliminates the narrow passages where barnacles and organisms would accumulate and obstruct movement.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The float body design allows for easy maintenance and cleaning. The reciprocative movement mechanism can be accessed and maintained without disassembling complex aperture structures, and the smooth surfaces of the float body are less prone to barnacle attachment compared to the previous aperture design.

Inventive Principle:
Principle #25Self-service
