Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If historical copper-salt based formulations (oxychlorides, hydroxides, Bordeaux mixture) are used to treat plant pathologies, then strong fungistatic and bactericide action is achieved, but the efficiency is greatly reduced due to loss of active principle and poor persistence requiring very frequent treatment

Engineering Contradiction:
Improvefungistatic and bactericide actionVSAvoidpersistence of copper on plants
Core Design Contradiction:
ReliabilityVSDuration of action of moving object

Solution Approach 1:

The patent combines copper salts with natural organic substances (plant extracts, humic substances, amino acids) to create composite formulations. This composite structure allows the organic components to act as carriers and protectors, reducing copper loss and extending its persistence on plant surfaces while maintaining the strong fungistatic and bactericide action.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The natural organic substances serve as intermediaries between the copper active principle and the plant environment. These organic carriers protect the copper ions from premature degradation and facilitate their controlled release, thereby extending the duration of action without compromising the initial efficacy.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If very frequent treatment is applied to maintain copper efficacy, then plant protection is maintained, but environmental and ecotoxicological risks increase due to accumulation of copper in the soil

Engineering Contradiction:
Improveplant protectionVSAvoidcopper accumulation in soil
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The formulation enables continuous protective action through controlled release mechanisms. The organic carriers gradually release copper ions over extended periods, maintaining effective protection levels without requiring frequent reapplication, thus preventing soil accumulation while ensuring continuous plant protection.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The patent changes the release parameters of copper by incorporating organic substances that modulate copper solubility and availability. This controlled parameter change allows maintaining effective copper concentrations at the plant surface for longer periods, reducing the frequency of applications and preventing environmental accumulation.

Inventive Principle:
Principle #35Parameter changes

3Quantity of substance

If complexed copper formulations (copper tribasic sulphate, copper tallate, copper chelates) are used to reduce copper dosages, then metal content is reduced, but accentuated phytotoxicity in plants and copper residues in vegetable tissues occur with health risks for consumers

Engineering Contradiction:
Improvecopper contentVSAvoidphytotoxicity and copper residues
Core Design Contradiction:
Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The patent extracts and utilizes specific natural organic components (humic substances, amino acids, plant extracts) that selectively bind copper in a manner that reduces its phytotoxicity while maintaining efficacy. These extracted organic substances act as selective protectors that allow lower copper dosages without causing harm to plants or leaving harmful residues.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The formulation changes the chemical parameters of copper by complexing it with natural organic substances, thereby modifying its bioavailability and toxicity profile. This parameter change allows reducing copper dosage while preventing phytotoxicity and minimizing residues in edible tissues through the protective effect of the organic carriers.

Inventive Principle:
Principle #35Parameter changes
