Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing Vanda orchid varieties lack distinct and stable purple-violet colored flowers with heavily dotted and blotched sepals and petals, and ruffled margins, which are desirable for horticultural interest and uniqueness.
Innovation Solution
The development of the Vanda cultivar 'SPCDW1507' through planned breeding, which exhibits unique purple-violet colored sepals and petals with heavy dark violet dots and ruffled margins, achieved through asexual reproduction by mericloning, maintaining stability across generations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If existing Vanda orchid varieties are used, then the flowers may have simple color patterns, but they lack distinct and stable purple-violet colored flowers with heavily dotted and blotched sepals and petals
Solution Approach 1:
The patent applies parameter changes by selectively breeding Vanda orchids with specific genetic parameters to achieve stable purple-violet coloration with heavy dotting and blotching patterns. The breeding program controlled floral color genes to produce consistent phenotypic expressions across generations, transforming the simple color patterns of existing varieties into distinct, stable complex patterns.
Solution Approach 2:
The patent applies local quality by developing orchids with non-uniform color distribution, where specific regions of the sepals and petals exhibit heavy dotting and blotching while other areas maintain different coloration. This creates localized variations in color pattern that enhance horticultural interest while maintaining overall stability through controlled breeding.
2Stability of the object's composition
If asexual reproduction by mericloning is used, then the unique characteristics can be maintained stably across generations, but the process requires controlled environmental conditions and specialized techniques
Solution Approach 1:
The patent applies copying through mericloning, where tissue culture plantlets are produced from parent plants and propagated asexually to create genetically identical copies. This copying process maintains the unique purple-violet coloration and dotting patterns stable across multiple generations without the genetic variation that would occur in sexual reproduction.
Solution Approach 2:
The patent applies the intermediary principle by using tissue culture technology as a mediator between the parent plant and the propagated offspring. The tissue culture laboratory serves as an intermediary system that enables asexual reproduction while maintaining controlled environmental conditions, bridging the gap between genetic stability and propagation efficiency.
3Adaptability or versatility
If the phenotype is allowed to vary with environmental conditions, then the plant can adapt to different conditions, but the unique characteristics may change without genotype variance
Solution Approach 1:
The patent applies parameter changes by monitoring and controlling environmental parameters such as temperature, light intensity, and humidity to minimize phenotypic variations. The breeding program adjusted these parameters to maintain consistent expression of the unique color patterns while allowing the plant to adapt to different growing conditions through controlled environmental management.
