Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If aeration cleaning method is used to remove contaminants from filtration membrane, then cleaning effectiveness is improved, but energy consumption increases significantly

Engineering Contradiction:
Improvecleaning effectivenessVSAvoidenergy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent replaces the pneumatic aeration system with a mechanical reciprocating motion system. The filtration membrane is moved back and forth mechanically along the feed water flow direction, substituting the need for high-energy air blowing while achieving similar contaminant removal through physical displacement and turbulence generation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The filtration membrane undergoes periodic reciprocating motion, moving forward and backward along the feed water flow. This periodic mechanical action generates turbulence and dislodges contaminants from the membrane surface, achieving cleaning effectiveness comparable to continuous aeration but with lower energy consumption.

Inventive Principle:
Principle #19Periodic action

2Reliability

If reciprocating frame is used to move multiple membrane support frames, then cleaning function is improved, but device complexity and manufacturing cost increase

Engineering Contradiction:
Improvecleaning functionVSAvoidstructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts and eliminates the complex reciprocating frame structure from the system. Instead of using a large frame to which multiple membrane support frames are coupled, the invention allows each membrane support frame to reciprocate independently or uses a simplified guiding mechanism, thereby reducing structural complexity and manufacturing costs while maintaining the cleaning function.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The system is segmented into independent membrane support frames that can reciprocate individually along guide rails, rather than being rigidly connected to a single large reciprocating frame. This segmentation simplifies the overall structure, reduces manufacturing complexity, and allows for easier maintenance of individual components.

Inventive Principle:
Principle #1Segmentation

3Reliability

If large reciprocating frame is used to accommodate multiple membrane modules, then cleaning coverage is improved, but ease of manufacture and maintenance deteriorates

Engineering Contradiction:
Improvecleaning coverageVSAvoidmanufacturing convenience
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The filtration system is divided into multiple independent membrane support frames that can be manufactured separately and then assembled. Each frame module is compact and can be produced using standard manufacturing processes, improving ease of manufacture compared to a single large reciprocating frame that would require custom fabrication and welding.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The standardized membrane support frame design serves multiple functions: it supports the filtration membrane, provides guiding surfaces for reciprocating motion, and can be easily assembled and disassembled for maintenance. This universal modular design simplifies manufacturing and enables easy replacement of individual modules without affecting the entire system.

Inventive Principle:
Principle #6Universality (Multi-functionality)

4Productivity

If multiple membrane support frames are coupled to single reciprocating frame, then cleaning efficiency is improved, but ease of operation and maintenance deteriorates

Engineering Contradiction:
Improvecleaning efficiencyVSAvoidoperational convenience
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

Instead of coupling multiple membrane support frames to a single reciprocating frame, the invention allows each frame to reciprocate independently along its own guide rails or uses a simplified common guiding structure. This segmentation improves operational convenience by allowing individual frames to be adjusted, removed, or maintained without affecting other frames, while still achieving coordinated cleaning action.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system transitions from a rigid coupled structure to a more dynamic configuration where membrane support frames can move independently or semi-independently. This dynamic arrangement allows for easier operation and maintenance, as individual components can be accessed and adjusted without requiring the entire assembly to be disassembled or stopped.

Inventive Principle:
Principle #15Dynamics
