Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of ornamental ground cover varieties with distinctive red and green coloration and robust propagation capabilities, limiting options for horticultural applications, particularly in shaded areas and ecological restoration.
Innovation Solution
The development of Tiarella cordifolia 'Delaware' with a compact mounding growth habit, red runners, and unique foliage coloration, which is well-suited for asexual propagation and maintains its characteristics across generations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If ornamental ground cover varieties are selected for distinctive coloration, then aesthetic appeal is improved, but propagation capabilities and reliability may be limited
Solution Approach 1:
The patent applies parameter changes by selecting and breeding plants with specific physiological and morphological parameters that ensure both aesthetic appeal and reliable propagation. The variety 'Delaware' exhibits stable parameters including distinctive red and green coloration, compact mounding growth habit, and robust runner formation, which are reliably transmitted across generations through asexual propagation methods.
2Productivity
If ground cover varieties are selected for dense stand formation, then productivity is improved, but adaptability to different horticultural applications may be reduced
Solution Approach 1:
The patent applies universality by developing a ground cover variety that performs multiple functions across diverse horticultural applications. Tiarella 'Delaware' is adapted for use in shaded areas, border plantings, ecological restoration projects, and general ground cover installations. The plant's combination of dense stand formation, distinctive coloration, and robust propagation capabilities enables it to successfully fulfill multiple horticultural roles.
3Reliability
If new ornamental varieties are discovered and preserved, then biodiversity is improved, but the risk of loss increases if not properly documented
Solution Approach 1:
The patent applies preliminary action by documenting the discovery, characteristics, and parentage of the new Tiarella variety before formal propagation and distribution. The detailed botanical description, growth habit documentation, and parentage recording were completed during the selection process in 2007, ensuring that all critical information is preserved before the variety enters commercial cultivation.
