Solution Overview

Problem

There is a need for an apple tree variety that matures for harvesting and shipment later than 'Honeycrisp' apples, with improved fruit characteristics such as shape, taste, texture, and storage life when grown under specific ecological conditions.

Innovation Solution

The development of the 'CN B110' apple tree variety, which is a late-mid season ripening tree with flatter fruit, excellent taste, firm crisp texture, and exceptional juiciness, and longer storage life compared to 'Honeycrisp', achieved through seed selection and propagation on EMLA 9 rootstock.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If apple trees are bred for early maturity like Honeycrisp, then harvesting time is earlier, but storage life is shorter and crispness is lost faster

Engineering Contradiction:

Improvestorage lifeVSAvoidmaturity timing

Core Design Contradiction:

Loss of timeVSDuration of action of stationary object

Solution Approach 1:

The patent changes the ripening parameter by breeding a new variety (CN B110) that matures 11 days later than Honeycrisp, thereby extending the storage life and maintaining crispness during prolonged storage while still achieving commercial harvestability

Inventive Principle:

Principle #35Parameter changes

2Shape

If apple fruit shape is bred for roundness, then traditional appearance is maintained, but market differentiation and consumer preference for unique shapes are reduced

Engineering Contradiction:

Improvefruit shapeVSAvoidmarket adaptability

Core Design Contradiction:

ShapeVSAdaptability or versatility

Solution Approach 1:

The patent applies asymmetry by breeding apple fruit with a distinctly flatter shape compared to the traditional round Honeycrisp, creating a unique marketable variety that differentiates itself while maintaining consumer appeal through excellent taste and texture

Inventive Principle:

Principle #4Asymmetry

3Reliability

If apple trees are propagated through traditional methods, then established varieties are maintained, but improvement in taste, texture, and juiciness is limited

Engineering Contradiction:

Improvevariety consistencyVSAvoidbreeding complexity

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent performs preliminary breeding actions by selecting and cross-breeding apple trees to produce a new variety with superior taste, firm crisp texture, and exceptional juiciness, then propagating this improved variety through controlled budding to ensure consistent quality while managing breeding complexity

Inventive Principle:

Principle #10Preliminary action
