Solution Overview

Problem

Existing Mandevilla plants lack compact growth and consistent flowering characteristics, with variations in flower color and size among different cultivars, limiting their use in horticultural applications.

Innovation Solution

Development of a new Mandevilla cultivar 'TVMD1027' through controlled cross-pollination, exhibiting upright growth, bright yellow flowers with orangish yellow throats, and stable flowering habits, suitable for container and garden use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If traditional Mandevilla cultivars are used, then large flowers can be achieved, but compact growth and consistent flowering are lacking

Engineering Contradiction:

Improveflower sizeVSAvoidgrowth habit consistency

Core Design Contradiction:

ShapeVSStability of the object's composition

Solution Approach 1:

The patent applies parameter changes by selecting and breeding for specific growth habit parameters (compactness, upright orientation) while maintaining flower size parameters. The new cultivar 'TVMD1027' exhibits modified growth parameters (more compact, upright habit) while preserving acceptable flower dimensions, resolving the contradiction between flower size and growth consistency.

Inventive Principle:

Principle #35Parameter changes

2Productivity

If Mandevilla plants are bred for vigorous growth, then productivity increases, but flowering consistency varies

Engineering Contradiction:

Improvegrowth vigorVSAvoidflowering consistency

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The breeding program employed feedback mechanisms by evaluating progeny for both growth vigor and flowering consistency, selecting only those individuals that met both criteria. The new cultivar 'TVMD1027' demonstrates this feedback-based selection, showing both vigorous growth and reliable, consistent flowering patterns across multiple observations.

Inventive Principle:

Principle #23Feedback

3Duration of action of moving object

If existing cultivars are used for container production, then early flowering can be achieved, but garden performance is limited

Engineering Contradiction:

Improveflowering timeVSAvoidgarden performance

Core Design Contradiction:

Duration of action of moving objectVSAdaptability or versatility

Solution Approach 1:

The patent applies universality by developing a cultivar suitable for multiple applications. The new Mandevilla 'TVMD1027' is bred to perform well in both container production (early flowering) and garden settings (vigorous growth, consistent performance), making it a multi-functional variety that addresses the limitations of cultivars specialized for single uses.

Inventive Principle:

Principle #6Universality (Multi-functionality)
