Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If conventional fat extraction methods are used on organic waste, then fat can be extracted, but the quality of extracted fat is insufficient for biofuel applications

Engineering Contradiction:
Improvefat qualityVSAvoidapplicability to all organic waste types
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The extraction process is divided into multiple sequential stages: initial fat extraction, filtration through various media (mesh filters, activated carbon, silica gel), and progressive purification steps. Each stage targets specific impurities, with the fat passing through increasingly refined separation media to remove contaminants of different sizes and types, ultimately achieving biofuel-grade quality

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention creates a universal extraction system that handles diverse organic waste types (food waste, agricultural residues, animal by-products) through a standardized multi-stage process. The same sequence of extraction, filtration, and purification steps applies regardless of the specific waste input, making the system adaptable to all organic materials while consistently producing high-quality fat

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

2Reliability

If waste is sorted and segregated by category, then each waste type can be treated appropriately, but the process complexity and collection requirements increase

Engineering Contradiction:
Improvetreatment effectivenessVSAvoidseparation and collection system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The extraction system is designed as a universal platform that accepts mixed organic waste categories without requiring pre-sorting. The multi-stage purification process automatically adapts to different waste types, using the same equipment and procedural sequence for food waste, agricultural residues, and animal by-products, thereby eliminating complex collection and segregation infrastructure

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

3Manufacturing precision

If multiple separation stages are implemented, then fat quality improves, but the processing time and operational complexity increase

Engineering Contradiction:
Improvefat purityVSAvoidprocessing duration
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The system implements continuous operation where fat extracted in one stage is immediately fed into the next purification stage without interruption. The multi-stage filtration process (mesh filters → activated carbon → silica gel) operates as a continuous flow system, eliminating idle time between stages and maintaining constant productive action throughout the entire purification sequence

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The extraction process begins with preliminary粗 extraction using less selective media that quickly remove bulk impurities, preparing the fat for subsequent finer purification steps. This preliminary separation reduces the burden on later stages, allowing them to focus on removing trace contaminants and achieving high purity more efficiently

Inventive Principle:
Principle #10Preliminary action
