Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple plant growth regulators are applied simultaneously to improve stress tolerance and growth, then the potential benefit is enhanced plant performance, but the difficulty of predicting the effect increases and the device complexity increases
Solution Approach 1:
The patent combines (S)-abscisic acid and malic acid into a single formulation applied together, merging the functions of two plant growth regulators to achieve synergistic effects in improving stress tolerance and growth without requiring separate applications
Solution Approach 2:
The patent specifies optimal concentration ratios of (S)-abscisic acid to malic acid (from 1:10 to 10:1 by weight) to achieve the desired effect, changing the parameters of concentration and proportion to optimize the combined action of the two regulators
2Reliability
If higher concentrations of plant growth regulators are applied to improve stress tolerance, then the stress protection may be enhanced, but the loss of energy and potential harmful effects increase
Solution Approach 1:
The patent optimizes the concentration parameters by specifying effective ranges for (S)-abscisic acid (0.1-1000 ppm) and malic acid (10-1000 ppm), identifying the optimal dosage to achieve stress tolerance while minimizing harmful effects
Solution Approach 2:
The patent utilizes malic acid, which in high concentrations can be harmful, but at optimized lower concentrations it provides beneficial effects including improved stress tolerance and enhanced photosynthesis, converting a potentially harmful substance into a beneficial agent
3Productivity
If plant growth regulators are applied to improve growth under normal conditions, then growth may be enhanced, but the cost of application and potential harmful effects increase
Solution Approach 1:
The patent specifies lower concentration ranges for growth promotion applications compared to stress tolerance applications, optimizing the dosage to achieve growth enhancement while minimizing costs and harmful effects
Solution Approach 2:
The patent applies low concentrations of the regulator mixture that are sufficient to achieve the desired growth effect without excessive application, following the principle of using the minimum effective amount
