Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elderberry cultivars face issues with inconsistent fruit ripening, low sugar content, susceptibility to diseases and insects, and poor cold tolerance, leading to lower quality products and increased post-harvest sorting challenges.
Innovation Solution
The introduction of the 'WCE' elderberry cultivar, which exhibits high chilling requirement, early ripening, uniform fruit ripening, resistance to phytophthora and stem blight, and cold tolerance, along with sweet berries and improved disease and insect resistance, allowing for easier harvesting and higher quality products.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional elderberry cultivars are used, then fruit ripening occurs, but ripening is inconsistent and only partial fruits ripen within clusters
Solution Approach 1:
The patent applies parameter changes by selecting and propagating plants with specific genetic traits that control fruit ripening behavior. The 'WCE' cultivar exhibits a genetic parameter change that enables synchronized ripening of 99% of fruits within clusters, transforming the ripening pattern from inconsistent to uniform through selective breeding and asexual propagation.
2Quantity of substance
If existing elderberry varieties are cultivated, then fruit production occurs, but sugar content is low (12 degrees Brix or lower)
Solution Approach 1:
The patent changes the chemical composition parameter of the fruit by developing a cultivar with elevated sugar content. The 'WCE' elderberry produces fruits with 16 degrees Brix or higher sugar content, representing a significant improvement in quantity of substance and product quality compared to conventional varieties.
3Reliability
If commercial elderberry cultivars are grown, then fruit yield is produced, but disease susceptibility increases (phytophthora, stem blight, stem blotch)
Solution Approach 1:
The patent applies self-service by developing a cultivar with inherent disease resistance traits. The 'WCE' elderberry naturally resists phytophthora, stem blight, and stem blotch without requiring external chemical interventions, enabling the plant to protect itself against diseases and maintain stable productivity.
4Temperature
If elderberry plants are exposed to cold temperatures, then survival is challenged, but most cultivars lack sufficient cold tolerance
Solution Approach 1:
The patent changes the physiological parameter of cold tolerance by selecting and propagating plants adapted to severe winter conditions. The 'WCE' cultivar demonstrates enhanced cold hardiness, surviving temperatures as low as -26°F (-31°C), which transforms the temperature tolerance parameter to ensure reliable winter survivability.
5Ease of operation
If elderberry clusters are harvested, then fruit collection occurs, but sorting is required due to inconsistent ripening
Solution Approach 1:
The patent changes the ripening uniformity parameter to eliminate the need for post-harvest sorting. The 'WCE' cultivar's genetic trait of synchronized fruit ripening ensures that 99% of fruits within clusters mature simultaneously, transforming the harvest operation from a complex sorting process to a simple collection task.

AI summary
A new and distinct variety of elderberry plant ‘WCE’ selected to provide a fruit which is firmer and sweeter in taste than the fruit of known cultivars and wild elderberry plants known to the Inventors. Compared to other wild and commercial cultivars known to the Inventors, the present invention yields clusters of berries which will consistently ripen 99% of the fruits within every fruit raceme.
