Solution Overview

Problem

The high cost of installing a large-scale lifting mechanism for small-sized hydroelectric power generation apparatuses in water channels, which generates excessive costs relative to the power output, as conventional methods require heavy machinery for maintenance and emergency lifting.

Innovation Solution

A hydroelectric power generation apparatus design featuring a hydroelectric power generation module with a rotary blade, a supporting part, and bars that allow the module to be easily lifted out of the water channel by pivoting, eliminating the need for large-scale devices and enabling manual operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a large-scale lifting mechanism is installed for lifting the hydroelectric power generation apparatus, then the apparatus can be lifted out of the water current, but the installation cost becomes excessive relative to the power generated

Engineering Contradiction:

Improvelifting capabilityVSAvoidinstallation cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The lifting mechanism is segmented into a simple bar structure that can be easily installed and removed, rather than a complex large-scale mechanism. The bar is divided into a first bar and a second bar that can be selectively assembled, reducing installation cost while maintaining lifting capability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent uses a simple, inexpensive bar structure instead of expensive large-scale lifting mechanisms. The bar can be easily manufactured and replaced, providing an cost-effective solution for lifting the hydroelectric power generation apparatus.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

2Reliability

If a large-scale lifting mechanism is used, then the apparatus can be lifted out of the water current, but the device complexity increases

Engineering Contradiction:

Improvelifting capabilityVSAvoidlifting mechanism complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The lifting mechanism is divided into simple components (first bar, second bar, supporting part) that can be independently assembled and disassembled. This segmentation reduces the overall complexity while maintaining the functional capability to lift the apparatus.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Instead of using a complex mechanism to lift the apparatus, the patent inverts the approach by using a simple bar that leverages the water current itself and manual operation to achieve lifting, thereby reducing device complexity.

Inventive Principle:

Principle #13The other way round (Inversion)

3Ease of manufacture

If a simple bar structure is used for lifting, then the installation cost is reduced, but the lifting force may be insufficient

Engineering Contradiction:

Improveinstallation costVSAvoidlifting force

Core Design Contradiction:

Ease of manufactureVSForce

Solution Approach 1:

The bar structure is designed to leverage the weight distribution and positioning of the hydroelectric power generation apparatus, using the apparatus's own weight and the water current as counterbalancing forces to achieve lifting with a simple structure.

Inventive Principle:

Principle #8Anti-weight (Counterweight)

Solution Approach 2:

The lifting mechanism utilizes spatial positioning and angular arrangement of the bars to generate mechanical advantage. By positioning the bars at specific angles and locations, sufficient lifting force is achieved without increasing structural complexity or cost.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

A hydroelectric power generation apparatus includes a hydroelectric power generation module, a supporting part, and a bar. The hydroelectric power generation module includes a rotary blade and a power generator that generates power by rotation of the rotary blade. The supporting part supports the hydroelectric power generation module. The supporting part can be installed at a water channel. The bar is connected to the supporting part to protrude from the supporting part. With one end of the bar closer to the supporting part or a portion of the supporting part serving as a center, the other end of the bar opposite to one end of the bar can be pivoted to switch a first state to a second state and vice versa.
