Prim 41 Sweet Cherry Tree Fruit Quality and Ripening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new sweet cherry tree variety that produces large, dark red-black fruits with a reniform shape, medium firmness, and a pleasant flavor, which also exhibits a balanced ripening time and strong stem attachment for improved shelf-life and export market potential.
Innovation Solution
The development of the 'Prim 41' sweet cherry tree variety, characterized by its kidney-shaped fruits, medium firmness, and dark red-black color, which ripens in about 10 days after 'Burlat', with a strong stem attachment and medium vigor growth habit, suitable for asexual propagation and high-yielding qualities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the cherry variety produces large fruits, then the fruit size is improved, but the firmness may be reduced
Solution Approach 1:
The patent applies parameter changes by selecting and propagating specific genetic traits that simultaneously achieve large fruit size (30-35mm diameter) and medium firmness. The variety 'Prim 41' was developed through controlled breeding to optimize the balance between fruit size and firmness, resulting in fruits that are both large and sufficiently firm for shipping and storage.
2Loss of time
If the cherry variety has early ripening time, then the market availability is improved, but the shelf-life may be reduced
Solution Approach 1:
The patent optimizes the ripening time parameter to achieve a middle ripening period (approximately 10 days after 'Burlat'), which balances early market availability with extended shelf-life. The variety maintains medium firmness and strong stem attachment, enabling the fruits to remain fresh during storage and shipping while still providing timely market entry.
3Manufacturing precision
If the cherry variety has weak tree growth, then the fruit quality is improved, but the productivity may be reduced
Solution Approach 1:
The patent balances tree vigor and fruit quality by selecting for medium vigor growth habit rather than either weak or vigorous growth. This intermediate growth parameter allows the tree to produce high-quality fruits with good flavor and firmness while maintaining adequate productivity for commercial cultivation.
4Duration of action of stationary object
If the cherry variety has strong stem attachment, then the shelf-life is improved, but the fruit size may be reduced
Solution Approach 1:
The patent optimizes multiple parameters simultaneously, including stem attachment strength and fruit size. The variety 'Prim 41' was selected to have long stems with strong attachment that remain green during storage, while also achieving large fruit size (30-35mm diameter). This multi-parameter optimization allows both large fruit size and strong stem attachment to coexist.
