Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for separating solid particles from running water are not efficient and consume excessive energy, necessitating an optimization of the operating cycle to enhance performance and reduce energy consumption.
Innovation Solution
A device with a separating unit inclined obliquely upwards, featuring fixed and movable grid bars, where the movable grid bars are actuated by a drive unit to draw solid particles out of the water and carry them upward along the fixed grid bars, with a method that includes detecting the position of the movable grid bars and adjusting the operation based on the water level to optimize the operating cycle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the movable grid bars continuously operate to transport solid particles, then the separation performance is maintained, but energy consumption increases
Solution Approach 1:
The drive unit operates intermittently with periodic cycles of upward movement (transport phase) and downward movement (return phase), rather than continuous operation. The controller activates the drive unit only when solid particles are detected on the grid bars, allowing the system to maintain separation performance while reducing energy consumption during periods when no particles need transport.
Solution Approach 2:
The system uses sensors to automatically detect the presence of solid particles on the grid bars and triggers the drive unit only when needed. This self-monitoring and self-activation mechanism eliminates the need for continuous operation, allowing the system to maintain reliability through automated detection and response while minimizing unnecessary energy consumption.
2Productivity
If the movable grid bars move upward continuously, then solid particles are transported efficiently, but the device complexity increases
Solution Approach 1:
The controller receives feedback from sensors that detect the position of the grid bars and the presence of solid particles. Based on this feedback, the controller intelligently controls the drive unit to activate only when particles are present and the grid bars are in the correct position, optimizing transport efficiency while managing system complexity through automated decision-making.
Solution Approach 2:
The system transitions from static continuous operation to dynamic intermittent operation, where the drive unit activates and deactivates based on real-time conditions. The grid bars alternate between upward transport movement and downward return movement, creating a dynamic operating cycle that adapts to the actual need for particle transport rather than maintaining constant motion.
3Productivity
If the grid bars move at high speed, then the processing capacity increases, but energy consumption increases
Solution Approach 1:
The drive unit operates in periodic cycles with high-speed upward movement for particle transport followed by lower-speed or idle return movement. This periodic high-speed operation maintains processing capacity when needed while reducing average energy consumption compared to sustained high-speed operation.
Solution Approach 2:
The system applies high-speed movement only partially - specifically during the upward transport phase when solid particles are present and need to be moved. During the downward return phase and when no particles are present, the drive unit operates at lower speed or remains idle, providing exactly the necessary action without excessive energy consumption.

AI summary
A separating grid includes a separating unit arranged, when in use, in a position of inclination obliquely upwards in the direction of flow of running water, fixed grid bars, movable grid bars, and a drive unit connected to the movable grid bars to actuate the movable grid bars to interact with the solid particles and to draw the solid particles out of the running water and to carry the solid particles upwards along the fixed grid bars. A position detection device detects the top position or the bottom position of the movable grid bars. A water level detection device detects the water level of the running water. A control device controls the drive unit according to information from the position detection device regarding the position of the movable grid bars and information from the water level detection device regarding the water level.
