Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If discharge electrodes and dust collecting electrodes are disposed close to each other, then the dust collection efficiency is improved, but excessive vibration is generated causing damage to the structure
Solution Approach 1:
The electrode assembly is segmented into multiple independent electrode units, each with its own support structure and spacing mechanism. This allows the electrodes to be positioned close together for efficient dust collection while each unit independently absorbs vibration, preventing structural damage.
Solution Approach 2:
A spacer member is introduced as an intermediary element between the discharge electrode and dust collecting electrode. This spacer maintains the optimal close distance for dust collection efficiency while mechanically isolating the electrodes to prevent vibration transmission and structural damage.
2Reliability
If discharge electrodes and dust collecting electrodes are spaced apart to reduce vibration, then structural damage is prevented, but dust collection efficiency decreases
Solution Approach 1:
The electrode system is divided into modular segments with independent vibration isolation mechanisms. This segmentation allows the electrodes to be positioned at optimal distances for both efficiency and vibration control, as each segment can be independently tuned.
Solution Approach 2:
The support structure utilizes composite materials with different damping characteristics at different locations. This allows the structure to maintain electrode proximity for efficiency while specific composite sections absorb vibration to prevent structural damage.
3Productivity
If the number of discharge electrodes and dust collecting electrodes is increased, then dust collection capacity is improved, but vibration and structural complexity increase
Solution Approach 1:
The electrode array is organized into repeating modular units that can be scaled to increase capacity. Each module contains a standardized number of discharge and collecting electrodes with fixed spacing, making the overall system less complex while maintaining high dust collection capacity through parallel processing.
