Solution Overview

Problem

There is a need for a distinct variety of apple tree that exhibits a more intense and diffused red skin surface color, which is not present in existing Fuji apple tree varieties, to differentiate it from others and enhance its market appeal.

Innovation Solution

The development of a new apple tree variety, 'FUJIKO', which features an intense red color on most of its skin surface, red coloration on the unexposed side, and good overcolor retention even under partial sunlight, achieved through asexual reproduction and grafting onto M9 rootstocks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If standard Fuji apple varieties are used, then the fruit produces adequate red coloration, but the red color intensity and diffusion on the skin surface is insufficient compared to the desired variety characteristics

Engineering Contradiction:

Improvered color intensity on skin surfaceVSAvoidcolor consistency under varying sunlight conditions

Core Design Contradiction:

Illumination intensityVSAdaptability or versatility

Solution Approach 1:

The patent applies parameter changes by selecting and propagating a specific mutant plant that exhibits altered pigmentation parameters compared to standard Fuji varieties. The 'FUJIKO' variety demonstrates intensified red coloration (parameter change in color intensity) while maintaining good overcolor under partial sunlight conditions, resolving the contradiction between color intensity and adaptability to varying sunlight conditions

Inventive Principle:

Principle #35Parameter changes

2Stability of the object's composition

If asexual reproduction through grafting is used to propagate the new variety, then the unique red color characteristics are firmly fixed and retained, but the process requires controlled environment and multiple generations of testing to ensure true-to-type reproduction

Engineering Contradiction:

Improveretention of red color characteristics through generationsVSAvoidcomplexity of propagation and testing process

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent employs copying through asexual reproduction methods, specifically grafting onto M9 rootstock, to propagate the new 'FUJIKO' variety. This copying process ensures that the unique red color characteristics are firmly fixed and retained through successive generations, achieving true-to-type reproduction. The controlled environment testing and multiple generations of verification ensure the stability of the copied characteristics

Inventive Principle:

Principle #26Copying
