Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new hybrid corn varieties is a slow and costly process that requires expertise, and existing hybrid corn varieties lose commercial competitiveness over time, necessitating a continuous need for novel varieties with improved characteristics to enhance yield production and provide flexibility against insects, weeds, and diseases.
Innovation Solution
The hybrid corn variety 373014 is developed by crossing inbred varieties DO65125 and XHB03, with specific physiological and morphological characteristics, and treated seeds are used to enhance resistance to adverse conditions, incorporating seed treatments that provide additional crop flexibility and cost-effective control against pests and diseases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If hybrid corn varieties are developed through traditional breeding processes, then yield and performance are improved, but the development time and cost increase significantly
Solution Approach 1:
The patent applies preliminary action by pre-selecting and characterizing parent inbred lines with specific desirable traits before crossing them. The inbred lines are developed and evaluated in advance for characteristics such as disease resistance, yield potential, and adaptability, so that when crossed, they produce hybrids with predictable improved performance. This preliminary preparation of parental material accelerates the overall breeding process while maintaining yield improvements.
2Productivity
If hybrid corn varieties are developed through traditional breeding processes, then yield and performance are improved, but development cost increases significantly
Solution Approach 1:
The patent applies self-service by developing a systematic approach where the breeding program generates its own parental lines and evaluates their performance through standardized field testing. The method uses the performance data from field trials to automatically identify superior inbred lines for crossing, reducing the need for external expertise and consultant services. This self-sufficient breeding system reduces development costs while maintaining yield improvements.
3Reliability
If existing hybrid corn varieties are used over time, then established performance is maintained, but commercial competitiveness is lost
Solution Approach 1:
The patent applies dynamics by implementing a continuous cycle of inbred line development, hybrid creation, and performance evaluation. Rather than relying on static existing varieties, the system dynamically generates new hybrid combinations from freshly developed inbred lines that incorporate emerging disease resistances and yield potentials. This dynamic renewal process maintains both performance stability and commercial competitiveness by continuously introducing improved genetic material.
4Object-affected harmful factors
If protective chemicals are applied to control pests and diseases, then crop protection is achieved, but environmental impact and production costs increase
Solution Approach 1:
The patent applies blessing in disguise by converting the potential harm of pest and disease susceptibility into a benefit through genetic resistance. By selecting and crossing inbred lines with natural resistance traits, the resulting hybrids inherently resist pests and diseases without requiring chemical interventions. This converts what would be a harmful vulnerability into a beneficial protective characteristic, reducing both chemical usage and environmental impact while maintaining effective crop protection.
