Composite Plant Cage Locking Clips Frictional Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plant cages, particularly tomato cages, face issues with corrosion and rust in steel cages and instability in plastic cages due to loose connections between horizontal and vertical supports, leading to structural failure under load.
Innovation Solution
A plant cage constructed from fiber-reinforced composite materials with locking clips featuring orthogonal clamps that securely attach horizontal and vertical supports, utilizing resilient tabs to create a frictional lock that prevents movement and deterioration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If steel components are used for plant cage construction, then the cage provides strong structural support, but the steel is quickly subject to corrosion and rust when exposed to the elements
Solution Approach 1:
The patent uses fiber-reinforced composite materials (such as fiberglass) to replace traditional steel components. These composite materials provide comparable structural strength while being inherently resistant to corrosion and rust, eliminating the deterioration problems that plague metal cages exposed to outdoor elements.
2Ease of manufacture
If C-shaped clips are used to attach horizontal supports to vertical rods, then the cage assembly is simple, but the clips can be moved with relative ease along the vertical rod resulting in unwanted movement
Solution Approach 1:
The patent introduces an intermediary locking mechanism consisting of a locking tab and corresponding locking groove. The locking tab extends from the C-shaped clip and engages with a groove in the vertical rod, acting as a mediator that prevents the clip from sliding along the rod while maintaining the simplicity of the original C-clip attachment method.
3Ease of manufacture
If clips at each end of the horizontal support are similarly oriented, then the manufacturing is simplified, but when one clip moves it tends to move the entire support, pulling the clip at the opposite end along
Solution Approach 1:
The patent employs asymmetric orientation of the C-shaped clips at opposite ends of horizontal supports. By rotating one clip 180 degrees relative to the other, the clips interlock when engaged on the vertical rod, creating a rigid connection that prevents movement of either clip while maintaining manufacturing simplicity through the use of identical clip components.

AI summary
A plant cage for supporting growing plants includes horizontal and vertical support rods connected by locking clips to form a cage of a desired size and shape. The locking clip includes a clamp at each end of an elongated body, with each clamp formed of two tabs extending outwardly at oblique angles, with an aperture formed in each tab for receiving a horizontal or vertical support rod. The outwardly extending tabs are resilient and flexible such that the tabs can be moved towards each other to a deflected position so that the apertures align and a support rod can be inserted, the resiliency of the material then biases the tabs away from each other when released so that the apertures become unaligned so that the inserted rod is frictionally captured by the clamp.
