Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new cultivar of Acer palmatum that exhibits unique characteristics such as contorted stem arrangement, moderate growth rate, and distinct autumn coloration, which are not adequately represented in existing varieties.
Innovation Solution
The cultivar 'CHACER01' features a variable and contorted stem arrangement, moderate growth rate, and orange/red autumn coloration, distinguished by its stable reproduction through grafting and propagation, showcasing these traits in specific environmental conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If conventional Acer palmatum varieties are used, then uniform and straight stem arrangement is achieved, but visual distinctiveness and aesthetic variety are limited
Solution Approach 1:
The cultivar 'CHACER01' exhibits asymmetric and contorted stem arrangements with branches bending at 30 to 45° angles at informal intervals, creating visual interest and aesthetic variety while maintaining the structural integrity of the tree
Solution Approach 2:
The cultivar displays variable stem arrangement parameters including branch angles of 30 to 45° bends, irregular internode spacing, and contorted growth patterns that differ from conventional straight-stemmed varieties, providing aesthetic versatility
2Productivity
If fast-growing Acer palmatum varieties are selected, then quicker establishment is achieved, but control over final plant size and proportions becomes difficult
Solution Approach 1:
The cultivar 'CHACER01' exhibits localized growth characteristics with contorted stem sections interspersed with normal growth patterns, allowing moderate overall growth rate while maintaining control over final plant size and creating distinctive visual patterns
Solution Approach 2:
The cultivar displays dynamic growth patterns where stem arrangement varies along the length of the plant, with branches bending at different angles and intervals, allowing the plant to adapt its shape while maintaining moderate growth rate
3Ease of operation
If yellow/orange autumn foliage varieties are used, then traditional autumn coloration is achieved, but distinctiveness and visual impact are reduced
Solution Approach 1:
The cultivar 'CHACER01' exhibits distinctive orange/red autumn foliage coloration that differs from the traditional yellow/orange colors of other Acer palmatum varieties, providing enhanced visual impact and distinctiveness during the autumn season
4Shape
If large leaf size varieties are selected, then visual prominence is achieved, but space requirements and maintenance complexity increase
Solution Approach 1:
The cultivar 'CHACER01' exhibits medium leaf size parameters that are smaller than traditional large-leafed Acer palmatum varieties, reducing space requirements and maintenance complexity while maintaining visual prominence through the distinctive contorted stem arrangement and autumn coloration

AI summary
A new and distinct Acer palmatum tree named ‘CHACER01’ is disclosed, characterized by a unique stem arrangement giving the appearance of contortions by having branches with 30° to 45° bends at variable intervals. Plants are reasonably fast growing for a dwarf Acer palmatum with approximately 10 to 15 cm of growth per year with a maximum height of 1.2 meters. Fall color is orange/red autumn and leaf size of similar size and shape as the original common Acer palmatum. The new variety is a dwarf tree, typically used for outdoor garden or container use.
