Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If micro-scale hydroelectric power generation is conducted through natural hydraulic force, then ecological power generation is achieved, but the power generation amount is limited due to scale limitation
Solution Approach 1:
The patent combines multiple power generation units into a systematic array along the channel, merging individual micro-scale generators into a collective system that achieves macro-scale power generation while preserving the ecological benefits of natural hydraulic force utilization
2Ease of operation
If water is allowed to flow freely through the channel, then natural water flow is maintained, but water cannot be accumulated to reach predetermined water level for systematic power generation
Solution Approach 1:
The one-way gate employs dynamic control mechanisms that adaptively adjust between open and closed states based on water level conditions, allowing free flow during normal conditions while accumulating water when predetermined levels are not reached, and releasing water systematically when power generation is required
3Quantity of substance
If the one-way gate prevents water backflow, then water accumulation is improved, but the device complexity increases
Solution Approach 1:
The one-way gate is designed with self-regulating features that automatically respond to water level changes and flow conditions, enabling the gate to control water accumulation and release without requiring complex external control systems or continuous manual intervention
4Duration of action of moving object
If the siphon body is used for water discharge, then continuous water flow is achieved, but the rotation speed of the impeller is insufficient for efficient power generation
Solution Approach 1:
The system accumulates water in advance to reach a predetermined water level before initiating power generation, creating a reservoir of potential energy that drives the siphon body to discharge water continuously at sufficient pressure and flow rate to achieve efficient impeller rotation speeds
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively accumulates water and enhances power generation effectiveness by preventing backflow and increasing rotation speed, thereby improving overall hydroelectric power generation efficiency.
Implementation Method 1
The top end of the one-way gate is disposed on the water guidance unit along a horizontal axial direction and positioned in the channel, and switchable between an open position and a close position. When the one-way gate is at the close position, the one-way gate prevents the water from flowing back toward the entrance.
Implementation Method 2
The water in the tank body enters the drawing segment through the siphon effect and continuously passes through the connection segment and the dropping segment to be discharged from the outlet.
Implementation Method 3
The operation speeding mechanism comprises a plurality of rotation axles that are sequentially and transmittably connected, wherein the preceding rotation axle is combined with the dropping segment and driven by the continuously discharged water to have a first rotation speed, and the succeeding rotation axle combined thereto is driven by the preceding rotation axle to have a second rotation speed, and the second rotation speed is higher than the first rotation speed.
Implementation Method 4
The generator comprises an output axle which is transmittably combined with the second rotation axle, to as to be driven by the third rotation axle to have a third rotation speed which is higher than the second rotation speed. The generator is driven by the third rotation speed to generate power.

AI summary
A hydroelectric power generation system using channel for water supply includes a water guidance unit, a one-way gate, and a plurality of power generation units. The water guidance unit includes a channel for water input, with an entrance provided in front of the channel for connection with a water source. The water entering the channel passes through the one-way gate and is prevented from flowing back to toward the entrance, so as to be effectively accumulated. When the water in the water guidance unit reaches the predetermined water level, the power generation units around the water guidance unit conducts power generation with the water, thereby improving the power generation effectiveness.
