Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for generating electricity from hydro energy in sewer lines are inefficient due to varying water flow rates, which affect the power generation capacity and can lead to clogging issues with debris, and lack effective mechanisms to maintain consistent water force on turbine blades.
Innovation Solution
A sewer line hydro power generator system featuring a flow control plate with a channel and a hydro turbine connected to an alternator, where the flow control plate pivots about an attachment hinge to maintain constant water force, and includes a pivot spring and pressure sensor to optimize power generation and prevent clogging, with the ability to raise and lower the hydro turbine using an actuator to adjust to varying flow rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a fixed hydro turbine is installed in the sewer line, then power generation is achieved, but the system cannot adapt to varying water flow rates and is prone to clogging
Solution Approach 1:
The flow control plate is designed to pivot dynamically about a hinge point in response to varying water flow rates. At low flow rates, the plate pivots to a closed position to prevent clogging, while at high flow rates it pivots to an open position to allow optimal water force on the turbine blades, enabling the system to adapt to changing conditions
Solution Approach 2:
The system uses the kinetic energy of the flowing water itself to automatically position the flow control plate through the hinge mechanism, eliminating the need for external actuators or control systems. The water flow self-regulates the plate position based on the flow rate
2Productivity
If the flow control plate is made fully open to maximize power generation, then power output increases, but clogging by debris becomes more likely
Solution Approach 1:
The flow control plate transitions between closed and open positions dynamically based on flow conditions. During low flow conditions when debris clogging is a risk, the plate remains closed. During high flow conditions when power generation is prioritized, the plate opens to allow maximum water force on the turbine
Solution Approach 2:
The hinge mechanism acts as an intermediary between the flow control plate and the water flow, allowing the plate to respond automatically to varying flow conditions by pivoting to appropriate positions that balance power generation and clogging prevention
3Productivity
If the hydro turbine is raised and lowered to optimize performance, then power generation efficiency improves, but the system complexity increases
Solution Approach 1:
The actuator is driven automatically by the kinetic energy of the water flow itself, eliminating the need for external power sources or complex control systems. The water flow self-regulates the turbine position based on flow conditions, maintaining simplicity while optimizing performance
Solution Approach 2:
The system replaces complex electrical or electronic control mechanisms with a simple mechanical actuator that is directly driven by water flow kinetic energy, reducing system complexity while achieving the desired turbine positioning
