Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If carrier-based biofertilisers are prepared using known techniques, then they can be produced and applied, but they exhibit low shelf-life and poor survival under adverse conditions

Engineering Contradiction:
Improveshelf-life and survival of microorganismsVSAvoidstorage duration
Core Design Contradiction:
ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The patent introduces a protective carrier material as an intermediary between the microorganisms and the external environment. This carrier acts as a mediator that protects microorganisms from adverse conditions during storage and application, thereby extending shelf-life and improving survival rates without requiring complex additional systems.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent modifies the physical and chemical parameters of the carrier material to optimize microorganism protection. By adjusting parameters such as porosity, moisture content, and chemical composition of the carrier, the system achieves extended storage duration and improved microorganism viability under varying environmental conditions.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If carrier-based biofertilisers are prepared using known techniques, then they can be produced, but they exhibit a high degree of contamination

Engineering Contradiction:
Improvepurity of biofertiliser compositionVSAvoidmanufacturing complexity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent implements preliminary sterilization and purification steps before the main biofertiliser formulation process. By pre-treating the carrier material and preparing sterile culture media in advance, the system prevents contamination during subsequent steps, achieving high purity without requiring overly complex continuous sterilization systems.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent replaces complex mechanical filtration and sterilization systems with biologically-based purification methods. By using selective microbial growth conditions and natural competitive exclusion principles, the system achieves contamination control through biochemical mechanisms rather than complex mechanical barriers.

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

3Reliability

Solution Approach 1:

The patent systematically controls and standardizes critical process parameters including incubation temperature, pH levels, moisture content, and carrier-to-microorganism ratios. By maintaining these parameters within optimized ranges throughout production, the system achieves consistent microorganism viability and activity, leading to reliable field performance without requiring excessively complex process control systems.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent develops a composite formulation combining specific carrier materials with selected microorganism strains in defined proportions. This composite approach ensures consistent interaction between components, providing reproducible performance characteristics across different production batches and field conditions while maintaining manageable process complexity.

Inventive Principle:
