Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bracket modules for tree pits are rectangular, leading to material waste and reduced root growth area due to mismatched shapes between the modules and round root balls.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If rectangular bracket modules are used, then the structure is simple and easy to manufacture, but material is wasted and root growth area is reduced due to shape mismatch with round root balls
Solution Approach 1:
The patent applies curvature by transitioning from rectangular bracket modules to hexagonal bracket elements with arc-shaped grooves. The hexagonal shape with curved grooves better approximates the circular shape of root balls, reducing material waste while maintaining manufacturing feasibility through standardized hexagonal geometry.
Solution Approach 2:
The bracket system is segmented into multiple hexagonal bracket elements that can be independently manufactured and then assembled together to form a complete circular bracket structure. This segmentation allows for easier manufacturing of individual components while achieving the optimal circular shape when assembled.
2Device complexity
If rectangular bracket modules are used, then the structure is simple, but the root growth area is reduced due to the mismatched shape
Solution Approach 1:
The patent replaces rectangular shapes with hexagonal shapes featuring arc-shaped grooves that collectively form a circular pattern. This curved geometry better matches the natural circular shape of root balls, maximizing the root growth area while the modular hexagonal design keeps the structural complexity manageable.
Solution Approach 2:
Multiple hexagonal bracket elements are merged and assembled together to form a complete circular bracket structure. This merging of standardized hexagonal units creates the optimal circular shape for root growth while maintaining the simplicity of using identical, easily manufactured components.
3Strength
If hexagonal bracket elements are used, then structural stability and strength are improved, but the device complexity increases
Solution Approach 1:
The hexagonal bracket elements with arc-shaped grooves provide enhanced structural strength and stability compared to rectangular modules. The curved geometry distributes loads more effectively and better approximates the circular root ball shape, while the standardized hexagonal form factor actually simplifies manufacturing and assembly.

AI summary
A bracket device for tree pit root management is provided, including at least three hexagonal bracket elements and a cover; wherein each hexagonal bracket element includes a center bracket, six side brackets, and six connecting brackets, a corner is formed between two adjacent side brackets, and an arc-shaped groove is formed at the top of each corner. The arc length of the top arc-shaped groove is one-third of the circumference of a circle. The connecting brackets connect the center bracket and the side brackets respectively. When three corners of the hexagonal bracket elements are connected, the top arc-shaped grooves of the three corners are connected to form a top circular groove. The cover comprises a convex ring inserted into the top circular groove. The bracket module formed by connecting multiple bracket devices supported by the columns to provide the overall structural strength and soil-supporting effect are better.
